CHAPTER I.

I GO TO STYLES

The intense interest aroused in the public by what was known at the time as "The Styles Case" has now somewhat subsided. Nevertheless, in view of the world-wide notoriety which attended it, I have been asked, both by my friend Poirot and the family themselves, to write an account of the whole story. This, we trust, will effectually silence the sensational rumours which still persist.

I will therefore briefly set down the circumstances which led to my being connected with the affair.

I had been invalided home from the Front; and, after spending some months in a rather depressing Convalescent Home, was given a month's sick leave. Having no near relations or friends, I was trying to make up my mind what to do, when I ran across John Cavendish. I had seen very little of him for some years. Indeed, I had never known him particularly well. He was a good fifteen years my senior, for one thing, though he hardly looked his forty-five years. As a boy, though, I had often stayed at Styles, his mother's place in Essex.

We had a good yarn about old times, and it ended in his inviting me down to Styles to spend my leave there.

"The mater will be delighted to see you again—after all those years," he added.

"Your mother keeps well?" I asked.

"Oh, yes. I suppose you know that she has married again?"

I am afraid I showed my surprise rather plainly. Mrs. Cavendish, who had married John's father when he was a widower with two sons, had been a handsome woman of middle-age as I remembered her. She certainly could not be a day less than seventy now. I recalled her as an energetic, autocratic personality, somewhat inclined to charitable and social notoriety, with a fondness for opening bazaars and playing the Lady Bountiful. She was a most generous woman, and possessed a considerable fortune of her own.

Their country-place, Styles Court, had been purchased by Mr. Cavendish early in their married life. He had been completely under his wife's ascendancy, so much so that, on dying, he left the place to her for her lifetime, as well as the larger part of his income; an arrangement that was distinctly unfair to his two sons. Their step-mother, however, had always been most generous to them; indeed, they were so young at the time of their father's remarriage that they always thought of her as their own mother.

Lawrence, the younger, had been a delicate youth. He had qualified as a doctor but early relinquished the profession of medicine, and lived at home while pursuing literary ambitions; though his verses never had any marked success.

John practiced for some time as a barrister, but had finally settled down to the more congenial life of a country squire. He had married two years ago, and had taken his wife to live at Styles, though I entertained a shrewd suspicion that he would have preferred his mother to increase his allowance, which would have enabled him to have a home of his own. Mrs. Cavendish, however, was a lady who liked to make her own plans, and expected other people to fall in with them, and in this case she certainly had the whip hand, namely: the purse strings.

John noticed my surprise at the news of his mother's remarriage and smiled rather ruefully.

"Rotten little bounder too!" he said savagely. "I can tell you, Hastings, it's making life jolly difficult for us. As for Evie—you remember Evie?"

"No."

"Oh, I suppose she was after your time. She's the mater's factotum, companion, Jack of all trades! A great sport—old Evie! Not precisely young and beautiful, but as game as they make them."

"You were going to say——?"

"Oh, this fellow! He turned up from nowhere, on the pretext of being a second cousin or something of Evie's, though she didn't seem particularly keen to acknowledge the relationship. The fellow is an absolute outsider, anyone can see that. He's got a great black beard, and wears patent leather boots in all weathers! But the mater cottoned to him at once, took him on as secretary—you know how she's always running a hundred societies?"

I nodded.

"Well, of course the war has turned the hundreds into thousands. No doubt the fellow was very useful to her. But you could have knocked us all down with a feather when, three months ago, she suddenly announced that she and Alfred were engaged! The fellow must be at least twenty years younger than she is! It's simply bare-faced fortune hunting; but there you are—she is her own mistress, and she's married him."

"It must be a difficult situation for you all."

"Difficult! It's damnable!"

Thus it came about that, three days later, I descended from the train at Styles St. Mary, an absurd little station, with no apparent reason for existence, perched up in the midst of green fields and country lanes. John Cavendish was waiting on the platform, and piloted me out to the car.

"Got a drop or two of petrol still, you see," he remarked. "Mainly owing to the mater's activities."

The village of Styles St. Mary was situated about two miles from the little station, and Styles Court lay a mile the other side of it. It was a still, warm day in early July. As one looked out over the flat Essex country, lying so green and peaceful under the afternoon sun, it seemed almost impossible to believe that, not so very far away, a great war was running its appointed course. I felt I had suddenly strayed into another world. As we turned in at the lodge gates, John said:

"I'm afraid you'll find it very quiet down here, Hastings."

"My dear fellow, that's just what I want."

"Oh, it's pleasant enough if you want to lead the idle life. I drill with the volunteers twice a week, and lend a hand at the farms. My wife works regularly 'on the land'. She is up at five every morning to milk, and keeps at it steadily until lunchtime. It's a jolly good life taking it all round—if it weren't for that fellow Alfred Inglethorp!" He checked the car suddenly, and glanced at his watch. "I wonder if we've time to pick up Cynthia. No, she'll have started from the hospital by now."

"Cynthia! That's not your wife?"

"No, Cynthia is a protegee of my mother's, the daughter of an old schoolfellow of hers, who married a rascally solicitor. He came a cropper, and the girl was left an orphan and penniless. My mother came to the rescue, and Cynthia has been with us nearly two years now. She works in the Red Cross Hospital at Tadminster, seven miles away."

As he spoke the last words, we drew up in front of the fine old house. A lady in a stout tweed skirt, who was bending over a flower bed, straightened herself at our approach.

"Hullo, Evie, here's our wounded hero! Mr. Hastings—Miss Howard."

Miss Howard shook hands with a hearty, almost painful, grip. I had an impression of very blue eyes in a sunburnt face. She was a pleasant-looking woman of about forty, with a deep voice, almost manly in its stentorian tones, and had a large sensible square body, with feet to match—these last encased in good thick boots. Her conversation, I soon found, was couched in the telegraphic style.

"Weeds grow like house afire. Can't keep even with 'em. Shall press you in. Better be careful."

"I'm sure I shall be only too delighted to make myself useful," I responded.

"Don't say it. Never does. Wish you hadn't later."

"You're a cynic, Evie," said John, laughing. "Where's tea to-day—inside or out?"

"Out. Too fine a day to be cooped up in the house."

"Come on then, you've done enough gardening for to-day. 'The labourer is worthy of his hire', you know. Come and be refreshed."

CHAPTER II.

THE 16TH AND 17TH OF JULY

I had arrived at Styles on the 5th of July. I come now to the events of the 16th and 17th of that month. For the convenience of the reader I will recapitulate the incidents of those days in as exact a manner as possible. They were elicited subsequently at the trial by a process of long and tedious cross-examinations.

I received a letter from Evelyn Howard a couple of days after her departure, telling me she was working as a nurse at the big hospital in Middlingham, a manufacturing town some fifteen miles away, and begging me to let her know if Mrs. Inglethorp should show any wish to be reconciled.

The only fly in the ointment of my peaceful days was Mrs. Cavendish's extraordinary, and, for my part, unaccountable preference for the society of Dr. Bauerstein. What she saw in the man I cannot imagine, but she was always asking him up to the house, and often went off for long expeditions with him. I must confess that I was quite unable to see his attraction.

The 16th of July fell on a Monday. It was a day of turmoil. The famous bazaar had taken place on Saturday, and an entertainment, in connection with the same charity, at which Mrs. Inglethorp was to recite a War poem, was to be held that night. We were all busy during the morning arranging and decorating the Hall in the village where it was to take place. We had a late luncheon and spent the afternoon resting in the garden. I noticed that John's manner was somewhat unusual. He seemed very excited and restless.

After tea, Mrs. Inglethorp went to lie down to rest before her efforts in the evening and I challenged Mary Cavendish to a single at tennis.

About a quarter to seven, Mrs. Inglethorp called us that we should be late as supper was early that night. We had rather a scramble to get ready in time; and before the meal was over the motor was waiting at the door.

The entertainment was a great success, Mrs. Inglethorp's recitation receiving tremendous applause. There were also some tableaux in which Cynthia took part. She did not return with us, having been asked to a supper party, and to remain the night with some friends who had been acting with her in the tableaux.

The following morning, Mrs. Inglethorp stayed in bed to breakfast, as she was rather overtired; but she appeared in her briskest mood about 12.30, and swept Lawrence and myself off to a luncheon party.

"Such a charming invitation from Mrs. Rolleston. Lady Tadminster's sister, you know. The Rollestons came over with the Conqueror—one of our oldest families."

Mary had excused herself on the plea of an engagement with Dr. Bauerstein.

We had a pleasant luncheon, and as we drove away Lawrence suggested that we should return by Tadminster, which was barely a mile out of our way, and pay a visit to Cynthia in her dispensary. Mrs. Inglethorp replied that this was an excellent idea, but as she had several letters to write she would drop us there, and we could come back with Cynthia in the pony-trap.

We were detained under suspicion by the hospital porter, until Cynthia appeared to vouch for us, looking very cool and sweet in her long white overall. She took us up to her sanctum, and introduced us to her fellow dispenser, a rather awe-inspiring individual, whom Cynthia cheerily addressed as "Nibs."

"What a lot of bottles!" I exclaimed, as my eye travelled round the small room. "Do you really know what's in them all?"

"Say something original," groaned Cynthia. "Every single person who comes up here says that. We are really thinking of bestowing a prize on the first individual who does not say: 'What a lot of bottles!' And I know the next thing you're going to say is: 'How many people have you poisoned?' "

I pleaded guilty with a laugh.

"If you people only knew how fatally easy it is to poison some one by mistake, you wouldn't joke about it. Come on, let's have tea. We've got all sorts of secret stories in that cupboard. No, Lawrence—that's the poison cupboard. The big cupboard—that's right."

We had a very cheery tea, and assisted Cynthia to wash up afterwards. We had just put away the last tea-spoon when a knock came at the door. The countenances of Cynthia and Nibs were suddenly petrified into a stern and forbidding expression.

"Come in," said Cynthia, in a sharp professional tone.

A young and rather scared looking nurse appeared with a bottle which she proffered to Nibs, who waved her towards Cynthia with the somewhat enigmatical remark:

"I'm not really here to-day."

Cynthia took the bottle and examined it with the severity of a judge.

"This should have been sent up this morning."

"Sister is very sorry. She forgot."

"Sister should read the rules outside the door."

I gathered from the little nurse's expression that there was not the least likelihood of her having the hardihood to retail this message to the dreaded "Sister".

"So now it can't be done until to-morrow," finished Cynthia.

CHAPTER III.

THE NIGHT OF THE TRAGEDY

To make this part of my story clear, I append the following plan of the first floor of Styles.

The servants' rooms are reached through the door B. They have no communication with the right wing, where the Inglethorps' rooms were situated.

It seemed to be the middle of the night when I was awakened by Lawrence Cavendish. He had a candle in his hand, and the agitation of his face told me at once that something was seriously wrong.

"What's the matter?" I asked, sitting up in bed, and trying to collect my scattered thoughts.

"We are afraid my mother is very ill. She seems to be having some kind of fit. Unfortunately she has locked herself in."

"I'll come at once."

I sprang out of bed; and, pulling on a dressing-gown, followed Lawrence along the passage and the gallery to the right wing of the house.

John Cavendish joined us, and one or two of the servants were standing round in a state of awe-stricken excitement. Lawrence turned to his brother.

"What do you think we had better do?"

Never, I thought, had his indecision of character been more apparent.

John rattled the handle of Mrs. Inglethorp's door violently, but with no effect. It was obviously locked or bolted on the inside. The whole household was aroused by now. The most alarming sounds were audible from the interior of the room. Clearly something must be done.

"Try going through Mr. Inglethorp's room, sir," cried Dorcas. "Oh, the poor mistress!"

Suddenly I realized that Alfred Inglethorp was not with us—that he alone had given no sign of his presence. John opened the door of his room. It was pitch dark, but Lawrence was following with the candle, and by its feeble light we saw that the bed had not been slept in, and that there was no sign of the room having been occupied.

We went straight to the connecting door. That, too, was locked or bolted on the inside. What was to be done?

"Oh, dear, sir," cried Dorcas, wringing her hands, "what ever shall we do?"

"We must try and break the door in, I suppose. It'll be a tough job, though. Here, let one of the maids go down and wake Baily and tell him to go for Dr. Wilkins at once. Now then, we'll have a try at the door. Half a moment, though, isn't there a door into Miss Cynthia's rooms?"

"Yes, sir, but that's always bolted. It's never been undone."

"Well, we might just see."

He ran rapidly down the corridor to Cynthia's room. Mary Cavendish was there, shaking the girl—who must have been an unusually sound sleeper—and trying to wake her.

In a moment or two he was back.

"No good. That's bolted too. We must break in the door. I think this one is a shade less solid than the one in the passage."

We strained and heaved together. The framework of the door was solid, and for a long time it resisted our efforts, but at last we felt it give beneath our weight, and finally, with a resounding crash, it was burst open.

We stumbled in together, Lawrence still holding his candle. Mrs. Inglethorp was lying on the bed, her whole form agitated by violent convulsions, in one of which she must have overturned the table beside her. As we entered, however, her limbs relaxed, and she fell back upon the pillows.

John strode across the room, and lit the gas. Turning to Annie, one of the housemaids, he sent her downstairs to the dining-room for brandy. Then he went across to his mother whilst I unbolted the door that gave on the corridor.

CHAPTER IV.

POIROT INVESTIGATES

The house which the Belgians occupied in the village was quite close to the park gates. One could save time by taking a narrow path through the long grass, which cut off the detours of the winding drive. So I, accordingly, went that way. I had nearly reached the lodge, when my attention was arrested by the running figure of a man approaching me. It was Mr. Inglethorp. Where had he been? How did he intend to explain his absence?

He accosted me eagerly.

"My God! This is terrible! My poor wife! I have only just heard."

"Where have you been?" I asked.

"Denby kept me late last night. It was one o'clock before we'd finished. Then I found that I'd forgotten the latch-key after all. I didn't want to arouse the household, so Denby gave me a bed."

"How did you hear the news?" I asked.

"Wilkins knocked Denby up to tell him. My poor Emily! She was so self-sacrificing—such a noble character. She over-taxed her strength."

A wave of revulsion swept over me. What a consummate hypocrite the man was!

"I must hurry on," I said, thankful that he did not ask me whither I was bound.

In a few minutes I was knocking at the door of Leastways Cottage.

Getting no answer, I repeated my summons impatiently. A window above me was cautiously opened, and Poirot himself looked out.

He gave an exclamation of surprise at seeing me. In a few brief words, I explained the tragedy that had occurred, and that I wanted his help.

"Wait, my friend, I will let you in, and you shall recount to me the affair whilst I dress."

In a few moments he had unbarred the door, and I followed him up to his room. There he installed me in a chair, and I related the whole story, keeping back nothing, and omitting no circumstance, however insignificant, whilst he himself made a careful and deliberate toilet.

I told him of my awakening, of Mrs. Inglethorp's dying words, of her husband's absence, of the quarrel the day before, of the scrap of conversation between Mary and her mother-in-law that I had overheard, of the former quarrel between Mrs. Inglethorp and Evelyn Howard, and of the latter's innuendoes.

I was hardly as clear as I could wish. I repeated myself several times, and occasionally had to go back to some detail that I had forgotten. Poirot smiled kindly on me.

"The mind is confused? Is it not so? Take time, mon ami. You are agitated; you are excited—it is but natural. Presently, when we are calmer, we will arrange the facts, neatly, each in his proper place. We will examine—and reject. Those of importance we will put on one side; those of no importance, pouf!"—he screwed up his cherub-like face, and puffed comically enough—"blow them away!"

"That's all very well," I objected, "but how are you going to decide what is important, and what isn't? That always seems the difficulty to me."

Poirot shook his head energetically. He was now arranging his moustache with exquisite care.

"Not so. Voyons! One fact leads to another—so we continue. Does the next fit in with that? A merveille! Good! We can proceed. This next little fact—no! Ah, that is curious! There is something missing—a link in the chain that is not there. We examine. We search. And that little curious fact, that possibly paltry little detail that will not tally, we put it here!" He made an extravagant gesture with his hand. "It is significant! It is tremendous!"

"Y—es—"

"Ah!" Poirot shook his forefinger so fiercely at me that I quailed before it. "Beware! Peril to the detective who says: 'It is so small—it does not matter. It will not agree. I will forget it.' That way lies confusion! Everything matters."

"I know. You always told me that. That's why I have gone into all the details of this thing whether they seemed to me relevant or not."

"And I am pleased with you. You have a good memory, and you have given me the facts faithfully. Of the order in which you present them, I say nothing—truly, it is deplorable! But I make allowances—you are upset. To that I attribute the circumstance that you have omitted one fact of paramount importance."

"What is that?" I asked.

"You have not told me if Mrs. Inglethorp ate well last night."

I stared at him. Surely the war had affected the little man's brain. He was carefully engaged in brushing his coat before putting it on, and seemed wholly engrossed in the task.

"I don't remember," I said. "And, anyway, I don't see——"

"You do not see? But it is of the first importance."

"I can't see why," I said, rather nettled. "As far as I can remember, she didn't eat much. She was obviously upset, and it had taken her appetite away. That was only natural."

"Yes," said Poirot thoughtfully, "it was only natural."

He opened a drawer, and took out a small despatch-case, then turned to me.

"Now I am ready. We will proceed to the chateau, and study matters on the spot. Excuse me, mon ami, you dressed in haste, and your tie is on one side. Permit me." With a deft gesture, he rearranged it.

"Ca y est! Now, shall we start?"

We hurried up the village, and turned in at the lodge gates. Poirot stopped for a moment, and gazed sorrowfully over the beautiful expanse of park, still glittering with morning dew.

"So beautiful, so beautiful, and yet, the poor family, plunged in sorrow, prostrated with grief."

He looked at me keenly as he spoke, and I was aware that I reddened under his prolonged gaze.

Was the family prostrated by grief? Was the sorrow at Mrs. Inglethorp's death so great? I realized that there was an emotional lack in the atmosphere. The dead woman had not the gift of commanding love. Her death was a shock and a distress, but she would not be passionately regretted.

Poirot seemed to follow my thoughts. He nodded his head gravely.

"No, you are right," he said, "it is not as though there was a blood tie. She has been kind and generous to these Cavendishes, but she was not their own mother. Blood tells—always remember that—blood tells."

"Poirot," I said, "I wish you would tell me why you wanted to know if Mrs. Inglethorp ate well last night? I have been turning it over in my mind, but I can't see how it has anything to do with the matter?"

He was silent for a minute or two as we walked along, but finally he said:

"I do not mind telling you—though, as you know, it is not my habit to explain until the end is reached. The present contention is that Mrs. Inglethorp died of strychnine poisoning, presumably administered in her coffee."

"Yes?"

"Well, what time was the coffee served?"

"About eight o'clock."

"Therefore she drank it between then and half-past eight— certainly not much later. Well, strychnine is a fairly rapid poison. Its effects would be felt very soon, probably in about an hour. Yet, in Mrs. Inglethorp's case, the symptoms do not manifest themselves until five o'clock the next morning: nine hours! But a heavy meal, taken at about the same time as the poison, might retard its effects, though hardly to that extent. Still, it is a possibility to be taken into account. But, according to you, she ate very little for supper, and yet the symptoms do not develop until early the next morning! Now that is a curious circumstance, my friend. Something may arise at the autopsy to explain it. In the meantime, remember it."

As we neared the house, John came out and met us. His face looked weary and haggard.

"This is a very dreadful business, Monsieur Poirot," he said. "Hastings has explained to you that we are anxious for no publicity?"

"I comprehend perfectly."

"You see, it is only suspicion so far. We have nothing to go upon."

"Precisely. It is a matter of precaution only."

John turned to me, taking out his cigarette-case, and lighting a cigarette as he did so.

"You know that fellow Inglethorp is back?"

"Yes. I met him."

John flung the match into an adjacent flower bed, a proceeding which was too much for Poirot's feelings. He retrieved it, and buried it neatly.

"It's jolly difficult to know how to treat him."

"That difficulty will not exist long," pronounced Poirot quietly.

John looked puzzled, not quite understanding the portent of this cryptic saying. He handed the two keys which Dr. Bauerstein had given him to me.

"Show Monsieur Poirot everything he wants to see."

"The rooms are locked?" asked Poirot.

"Dr. Bauerstein considered it advisable."

Poirot nodded thoughtfully.

"Then he is very sure. Well, that simplifies matters for us."

We went up together to the room of the tragedy. For convenience I append a plan of the room and the principal articles of furniture in it.

Poirot locked the door on the inside, and proceeded to a minute inspection of the room. He darted from one object to the other with the agility of a grasshopper. I remained by the door, fearing to obliterate any clues. Poirot, however, did not seem grateful to me for my forbearance.

"What have you, my friend," he cried, "that you remain there like—how do you say it?—ah, yes, the stuck pig?"

I explained that I was afraid of obliterating any foot-marks.

"Foot-marks? But what an idea! There has already been practically an army in the room! What foot-marks are we likely to find? No, come here and aid me in my search. I will put down my little case until I need it."

He did so, on the round table by the window, but it was an ill-advised proceeding; for, the top of it being loose, it tilted up, and precipitated the despatch-case on the floor.

"Eh voila une table!" cried Poirot. "Ah, my friend, one may live in a big house and yet have no comfort."

After which piece of moralizing, he resumed his search.

A small purple despatch-case, with a key in the lock, on the writing-table, engaged his attention for some time. He took out the key from the lock, and passed it to me to inspect. I saw nothing peculiar, however. It was an ordinary key of the Yale type, with a bit of twisted wire through the handle.

Next, he examined the framework of the door we had broken in, assuring himself that the bolt had really been shot. Then he went to the door opposite leading into Cynthia's room. That door was also bolted, as I had stated. However, he went to the length of unbolting it, and opening and shutting it several times; this he did with the utmost precaution against making any noise. Suddenly something in the bolt itself seemed to rivet his attention. He examined it carefully, and then, nimbly whipping out a pair of small forceps from his case, he drew out some minute particle which he carefully sealed up in a tiny envelope.

On the chest of drawers there was a tray with a spirit lamp and a small saucepan on it. A small quantity of a dark fluid remained in the saucepan, and an empty cup and saucer that had been drunk out of stood near it.

I wondered how I could have been so unobservant as to overlook this. Here was a clue worth having. Poirot delicately dipped his finger into liquid, and tasted it gingerly. He made a grimace.

"Coco—with—I think—rum in it."

He passed on to the debris on the floor, where the table by the bed had been overturned. A reading-lamp, some books, matches, a bunch of keys, and the crushed fragments of a coffee-cup lay scattered about.

"Ah, this is curious," said Poirot.

"I must confess that I see nothing particularly curious about it."

"You do not? Observe the lamp—the chimney is broken in two places; they lie there as they fell. But see, the coffee-cup is absolutely smashed to powder."

CHAPTER V.

"IT ISN'T STRYCHNINE, IS IT?"

"Where did you find this?" I asked Poirot, in lively curiosity.

"In the waste-paper basket. You recognise the handwriting?"

"Yes, it is Mrs. Inglethorp's. But what does it mean?"

Poirot shrugged his shoulders.

"I cannot say—but it is suggestive."

A wild idea flashed across me. Was it possible that Mrs. Inglethorp's mind was deranged? Had she some fantastic idea of demoniacal possession? And, if that were so, was it not also possible that she might have taken her own life?

I was about to expound these theories to Poirot, when his own words distracted me.

"Come," he said, "now to examine the coffee-cups!"

"My dear Poirot! What on earth is the good of that, now that we know about the coco?"

"Oh, la la! That miserable coco!" cried Poirot flippantly.

He laughed with apparent enjoyment, raising his arms to heaven in mock despair, in what I could not but consider the worst possible taste.

"And, anyway," I said, with increasing coldness, "as Mrs. Inglethorp took her coffee upstairs with her, I do not see what you expect to find, unless you consider it likely that we shall discover a packet of strychnine on the coffee tray!"

Poirot was sobered at once.

"Come, come, my friend," he said, slipping his arms through mine. "Ne vous fachez pas! Allow me to interest myself in my coffee-cups, and I will respect your coco. There! Is it a bargain?"

He was so quaintly humorous that I was forced to laugh; and we went together to the drawing-room, where the coffee-cups and tray remained undisturbed as we had left them.

Poirot made me recapitulate the scene of the night before, listening very carefully, and verifying the position of the various cups.

"So Mrs. Cavendish stood by the tray—and poured out. Yes. Then she came across to the window where you sat with Mademoiselle Cynthia. Yes. Here are the three cups. And the cup on the mantel-piece, half drunk, that would be Mr. Lawrence Cavendish's. And the one on the tray?"

"John Cavendish's. I saw him put it down there."

"Good. One, two, three, four, five—but where, then, is the cup of Mr. Inglethorp?"

"He does not take coffee."

"Then all are accounted for. One moment, my friend."

With infinite care, he took a drop or two from the grounds in each cup, sealing them up in separate test tubes, tasting each in turn as he did so. His physiognomy underwent a curious change. An expression gathered there that I can only describe as half puzzled, and half relieved.

"Bien!" he said at last. "It is evident! I had an idea—but clearly I was mistaken. Yes, altogether I was mistaken. Yet it is strange. But no matter!"

And, with a characteristic shrug, he dismissed whatever it was that was worrying him from his mind. I could have told him from the beginning that this obsession of his over the coffee was bound to end in a blind alley, but I restrained my tongue. After all, though he was old, Poirot had been a great man in his day.

"Breakfast is ready," said John Cavendish, coming in from the hall. "You will breakfast with us, Monsieur Poirot?"

Poirot acquiesced. I observed John. Already he was almost restored to his normal self. The shock of the events of the last night had upset him temporarily, but his equable poise soon swung back to the normal. He was a man of very little imagination, in sharp contrast with his brother, who had, perhaps, too much.

Ever since the early hours of the morning, John had been hard at work, sending telegrams—one of the first had gone to Evelyn Howard—writing notices for the papers, and generally occupying himself with the melancholy duties that a death entails.

"May I ask how things are proceeding?" he said. "Do your investigations point to my mother having died a natural death— or—or must we prepare ourselves for the worst?"

"I think, Mr. Cavendish," said Poirot gravely, "that you would do well not to buoy yourself up with any false hopes. Can you tell me the views of the other members of the family?"

"My brother Lawrence is convinced that we are making a fuss over nothing. He says that everything points to its being a simple case of heart failure."

"He does, does he? That is very interesting—very interesting," murmured Poirot softly. "And Mrs. Cavendish?"

A faint cloud passed over John's face.

"I have not the least idea what my wife's views on the subject are."

The answer brought a momentary stiffness in its train. John broke the rather awkward silence by saying with a slight effort:

"I told you, didn't I, that Mr. Inglethorp has returned?"

Poirot bent his head.

"It's an awkward position for all of us. Of course one has to treat him as usual—but, hang it all, one's gorge does rise at sitting down to eat with a possible murderer!"

Poirot nodded sympathetically.

"I quite understand. It is a very difficult situation for you, Mr. Cavendish. I would like to ask you one question. Mr. Inglethorp's reason for not returning last night was, I believe, that he had forgotten the latch-key. Is not that so?"

"Yes."

"I suppose you are quite sure that the latch-key was forgotten—that he did not take it after all?"

"I have no idea. I never thought of looking. We always keep it in the hall drawer. I'll go and see if it's there now."

Poirot held up his hand with a faint smile.

"No, no, Mr. Cavendish, it is too late now. I am certain that you would find it. If Mr. Inglethorp did take it, he has had ample time to replace it by now."

"But do you think——"

"I think nothing. If anyone had chanced to look this morning before his return, and seen it there, it would have been a valuable point in his favour. That is all."

John looked perplexed.

"Do not worry," said Poirot smoothly. "I assure you that you need not let it trouble you. Since you are so kind, let us go and have some breakfast."

Every one was assembled in the dining-room. Under the circumstances, we were naturally not a cheerful party. The reaction after a shock is always trying, and I think we were all suffering from it. Decorum and good breeding naturally enjoined that our demeanour should be much as usual, yet I could not help wondering if this self-control were really a matter of great difficulty. There were no red eyes, no signs of secretly indulged grief. I felt that I was right in my opinion that Dorcas was the person most affected by the personal side of the tragedy.

I pass over Alfred Inglethorp, who acted the bereaved widower in a manner that I felt to be disgusting in its hypocrisy. Did he know that we suspected him, I wondered. Surely he could not be unaware of the fact, conceal it as we would. Did he feel some secret stirring of fear, or was he confident that his crime would go unpunished? Surely the suspicion in the atmosphere must warn him that he was already a marked man.

But did every one suspect him? What about Mrs. Cavendish? I watched her as she sat at the head of the table, graceful, composed, enigmatic. In her soft grey frock, with white ruffles at the wrists falling over her slender hands, she looked very beautiful. When she chose, however, her face could be sphinx-like in its inscrutability. She was very silent, hardly opening her lips, and yet in some queer way I felt that the great strength of her personality was dominating us all.

And little Cynthia? Did she suspect? She looked very tired and ill, I thought. The heaviness and languor of her manner were very marked. I asked her if she were feeling ill, and she answered frankly:

"Yes, I've got the most beastly headache."

"Have another cup of coffee, mademoiselle?" said Poirot solicitously. "It will revive you. It is unparalleled for the mal de tete." He jumped up and took her cup.

"No sugar," said Cynthia, watching him, as he picked up the sugar-tongs.

"No sugar? You abandon it in the war-time, eh?"

"No, I never take it in coffee."

"Sacre!" murmured Poirot to himself, as he brought back the replenished cup.

Only I heard him, and glancing up curiously at the little man I saw that his face was working with suppressed excitement, and his eyes were as green as a cat's. He had heard or seen something that had affected him strongly—but what was it? I do not usually label myself as dense, but I must confess that nothing out of the ordinary had attracted my attention.

In another moment, the door opened and Dorcas appeared.

"Mr. Wells to see you, sir," she said to John.

I remembered the name as being that of the lawyer to whom Mrs. Inglethorp had written the night before.

John rose immediately.

"Show him into my study." Then he turned to us. "My mother's lawyer," he explained. And in a lower voice: "He is also Coroner—you understand. Perhaps you would like to come with me?"

We acquiesced and followed him out of the room. John strode on ahead and I took the opportunity of whispering to Poirot:

"There will be an inquest then?"

Poirot nodded absently. He seemed absorbed in thought; so much so that my curiosity was aroused.

"What is it? You are not attending to what I say."

"It is true, my friend. I am much worried."

"Why?"

"Because Mademoiselle Cynthia does not take sugar in her coffee."

"What? You cannot be serious?"

"But I am most serious. Ah, there is something there that I do not understand. My instinct was right."

"What instinct?"

"The instinct that led me to insist on examining those coffee-cups. Chut! no more now!"

We followed John into his study, and he closed the door behind us.

Mr. Wells was a pleasant man of middle-age, with keen eyes, and the typical lawyer's mouth. John introduced us both, and explained the reason of our presence.

"You will understand, Wells," he added, "that this is all strictly private. We are still hoping that there will turn out to be no need for investigation of any kind."

"Quite so, quite so," said Mr. Wells soothingly. "I wish we could have spared you the pain and publicity of an inquest, but of course it's quite unavoidable in the absence of a doctor's certificate."

"Yes, I suppose so."

"Clever man, Bauerstein. Great authority on toxicology, I believe."

"Indeed," said John with a certain stiffness in his manner. Then he added rather hesitatingly: "Shall we have to appear as witnesses—all of us, I mean?"

"You, of course—and ah—er—Mr.—er—Inglethorp."

A slight pause ensued before the lawyer went on in his soothing manner:

"Any other evidence will be simply confirmatory, a mere matter of form."

"I see."

A faint expression of relief swept over John's face. It puzzled me, for I saw no occasion for it.

"If you know of nothing to the contrary," pursued Mr. Wells, "I had thought of Friday. That will give us plenty of time for the doctor's report. The post-mortem is to take place to-night, I believe?"

"Yes."

"Then that arrangement will suit you?"

"Perfectly."

"I need not tell you, my dear Cavendish, how distressed I am at this most tragic affair."

"Can you give us no help in solving it, monsieur?" interposed Poirot, speaking for the first time since we had entered the room.

"I?"

"Yes, we heard that Mrs. Inglethorp wrote to you last night. You should have received the letter this morning."

"I did, but it contains no information. It is merely a note asking me to call upon her this morning, as she wanted my advice on a matter of great importance."

"She gave you no hint as to what that matter might be?"

"Unfortunately, no."

"That is a pity," said John.

"A great pity," agreed Poirot gravely.

There was silence. Poirot remained lost in thought for a few minutes. Finally he turned to the lawyer again.

"Mr. Wells, there is one thing I should like to ask you—that is, if it is not against professional etiquette. In the event of Mrs. Inglethorp's death, who would inherit her money?"

The lawyer hesitated a moment, and then replied:

"The knowledge will be public property very soon, so if Mr. Cavendish does not object——"

"Not at all," interpolated John.

"I do not see any reason why I should not answer your question. By her last will, dated August of last year, after various unimportant legacies to servants, etc., she gave her entire fortune to her stepson, Mr. John Cavendish."

"Was not that—pardon the question, Mr. Cavendish—rather unfair to her other stepson, Mr. Lawrence Cavendish?"

"No, I do not think so. You see, under the terms of their father's will, while John inherited the property, Lawrence, at his stepmother's death, would come into a considerable sum of money. Mrs. Inglethorp left her money to her elder stepson, knowing that he would have to keep up Styles. It was, to my mind, a very fair and equitable distribution."

Poirot nodded thoughtfully.

"I see. But I am right in saying, am I not, that by your English law that will was automatically revoked when Mrs. Inglethorp remarried?"

Mr. Wells bowed his head.

"As I was about to proceed, Monsieur Poirot, that document is now null and void."

"Hein!" said Poirot. He reflected for a moment, and then asked: "Was Mrs. Inglethorp herself aware of that fact?"

"I do not know. She may have been."

"She was," said John unexpectedly. "We were discussing the matter of wills being revoked by marriage only yesterday."

"Ah! One more question, Mr. Wells. You say 'her last will.' Had Mrs. Inglethorp, then, made several former wills?"

"On an average, she made a new will at least once a year," said Mr. Wells imperturbably. "She was given to changing her mind as to her testamentary dispositions, now benefiting one, now another member of her family."

"Suppose," suggested Poirot, "that, unknown to you, she had made a new will in favour of some one who was not, in any sense of the word, a member of the family—we will say Miss Howard, for instance—would you be surprised?"

"Not in the least."

"Ah!" Poirot seemed to have exhausted his questions.

I drew close to him, while John and the lawyer were debating the question of going through Mrs. Inglethorp's papers.

"Do you think Mrs. Inglethorp made a will leaving all her money to Miss Howard?" I asked in a low voice, with some curiosity.

Poirot smiled.

"No."

"Then why did you ask?"

"Hush!"

CHAPTER VI.

THE INQUEST

In the interval before the inquest, Poirot was unfailing in his activity. Twice he was closeted with Mr. Wells. He also took long walks into the country. I rather resented his not taking me into his confidence, the more so as I could not in the least guess what he was driving at.

It occurred to me that he might have been making inquiries at Raikes's farm; so, finding him out when I called at Leastways Cottage on Wednesday evening, I walked over there by the fields, hoping to meet him. But there was no sign of him, and I hesitated to go right up to the farm itself. As I walked away, I met an aged rustic, who leered at me cunningly.

"You'm from the Hall, bain't you?" he asked.

"Yes. I'm looking for a friend of mine whom I thought might have walked this way."

"A little chap? As waves his hands when he talks? One of them Belgies from the village?"

"Yes," I said eagerly. "He has been here, then?"

"Oh, ay, he's been here, right enough. More'n once too. Friend of yours, is he? Ah, you gentlemen from the Hall—you'n a pretty lot!" And he leered more jocosely than ever.

"Why, do the gentlemen from the Hall come here often?" I asked, as carelessly as I could.

He winked at me knowingly.

"One does, mister. Naming no names, mind. And a very liberal gentleman too! Oh, thank you, sir, I'm sure."

I walked on sharply. Evelyn Howard had been right then, and I experienced a sharp twinge of disgust, as I thought of Alfred Inglethorp's liberality with another woman's money. Had that piquant gipsy face been at the bottom of the crime, or was it the baser mainspring of money? Probably a judicious mixture of both.

On one point, Poirot seemed to have a curious obsession. He once or twice observed to me that he thought Dorcas must have made an error in fixing the time of the quarrel. He suggested to her repeatedly that it was 4.30, and not 4 o'clock when she had heard the voices.

But Dorcas was unshaken. Quite an hour, or even more, had elapsed between the time when she had heard the voices and 5 o'clock, when she had taken tea to her mistress.

The inquest was held on Friday at the Stylites Arms in the village. Poirot and I sat together, not being required to give evidence.

The preliminaries were gone through. The jury viewed the body, and John Cavendish gave evidence of identification.

Further questioned, he described his awakening in the early hours of the morning, and the circumstances of his mother's death.

The medical evidence was next taken. There was a breathless hush, and every eye was fixed on the famous London specialist, who was known to be one of the greatest authorities of the day on the subject of toxicology.

In a few brief words, he summed up the result of the post-mortem. Shorn of its medical phraseology and technicalities, it amounted to the fact that Mrs. Inglethorp had met her death as the result of strychnine poisoning. Judging from the quantity recovered, she must have taken not less than three-quarters of a grain of strychnine, but probably one grain or slightly over.

"Is it possible that she could have swallowed the poison by accident?" asked the Coroner.

"I should consider it very unlikely. Strychnine is not used for domestic purposes, as some poisons are, and there are restrictions placed on its sale."

"Does anything in your examination lead you to determine how the poison was administered?"

"No."

"You arrived at Styles before Dr. Wilkins, I believe?"

"That is so. The motor met me just outside the lodge gates, and I hurried there as fast as I could."

"Will you relate to us exactly what happened next?"

"I entered Mrs. Inglethorp's room. She was at that moment in a typical tetanic convulsion. She turned towards me, and gasped out: 'Alfred—Alfred——' "

"Could the strychnine have been administered in Mrs. Inglethorp's after-dinner coffee which was taken to her by her husband?"

"Possibly, but strychnine is a fairly rapid drug in its action. The symptoms appear from one to two hours after it has been swallowed. It is retarded under certain conditions, none of which, however, appear to have been present in this case. I presume Mrs. Inglethorp took the coffee after dinner about eight o'clock, whereas the symptoms did not manifest themselves until the early hours of the morning, which, on the face of it, points to the drug having been taken much later in the evening."

"Mrs. Inglethorp was in the habit of drinking a cup of coco in the middle of the night. Could the strychnine have been administered in that?"

"No, I myself took a sample of the coco remaining in the saucepan and had it analysed. There was no strychnine present."

I heard Poirot chuckle softly beside me.

"How did you know?" I whispered.

"Listen."

"I should say"—the doctor was continuing—"that I would have been considerably surprised at any other result."

"Why?"

"Simply because strychnine has an unusually bitter taste. It can be detected in a solution of 1 in 70,000, and can only be disguised by some strongly flavoured substance. Coco would be quite powerless to mask it."

One of the jury wanted to know if the same objection applied to coffee.

"No. Coffee has a bitter taste of its own which would probably cover the taste of strychnine."

"Then you consider it more likely that the drug was administered in the coffee, but that for some unknown reason its action was delayed."

"Yes, but, the cup being completely smashed, there is no possibility of analyzing its contents."

This concluded Dr. Bauerstein's evidence. Dr. Wilkins corroborated it on all points. Sounded as to the possibility of suicide, he repudiated it utterly. The deceased, he said, suffered from a weak heart, but otherwise enjoyed perfect health, and was of a cheerful and well-balanced disposition. She would be one of the last people to take her own life.

Lawrence Cavendish was next called. His evidence was quite unimportant, being a mere repetition of that of his brother. Just as he was about to step down, he paused, and said rather hesitatingly:

"I should like to make a suggestion if I may?"

He glanced deprecatingly at the Coroner, who replied briskly:

"Certainly, Mr. Cavendish, we are here to arrive at the truth of this matter, and welcome anything that may lead to further elucidation."

"It is just an idea of mine," explained Lawrence. "Of course I may be quite wrong, but it still seems to me that my mother's death might be accounted for by natural means."

"How do you make that out, Mr. Cavendish?"

"My mother, at the time of her death, and for some time before it, was taking a tonic containing strychnine."

"Ah!" said the Coroner.

The jury looked up, interested.

"I believe," continued Lawrence, "that there have been cases where the cumulative effect of a drug, administered for some time, has ended by causing death. Also, is it not possible that she may have taken an overdose of her medicine by accident?"

"This is the first we have heard of the deceased taking strychnine at the time of her death. We are much obliged to you, Mr. Cavendish."

Dr. Wilkins was recalled and ridiculed the idea.

"What Mr. Cavendish suggests is quite impossible. Any doctor would tell you the same. Strychnine is, in a certain sense, a cumulative poison, but it would be quite impossible for it to result in sudden death in this way. There would have to be a long period of chronic symptoms which would at once have attracted my attention. The whole thing is absurd."

"And the second suggestion? That Mrs. Inglethorp may have inadvertently taken an overdose?"

CHAPTER VII.

POIROT PAYS HIS DEBTS

As we came out of the Stylites Arms, Poirot drew me aside by a gentle pressure of the arm. I understood his object. He was waiting for the Scotland Yard men.

In a few moments, they emerged, and Poirot at once stepped forward, and accosted the shorter of the two.

"I fear you do not remember me, Inspector Japp."

"Why, if it isn't Mr. Poirot!" cried the Inspector. He turned to the other man. "You've heard me speak of Mr. Poirot? It was in 1904 he and I worked together—the Abercrombie forgery case—you remember, he was run down in Brussels. Ah, those were great days, moosier. Then, do you remember 'Baron' Altara? There was a pretty rogue for you! He eluded the clutches of half the police in Europe. But we nailed him in Antwerp—thanks to Mr. Poirot here."

As these friendly reminiscences were being indulged in, I drew nearer, and was introduced to Detective-Inspector Japp, who, in his turn, introduced us both to his companion, Superintendent Summerhaye.

"I need hardly ask what you are doing here, gentlemen," remarked Poirot.

Japp closed one eye knowingly.

"No, indeed. Pretty clear case I should say."

But Poirot answered gravely:

"There I differ from you."

"Oh, come!" said Summerhaye, opening his lips for the first time. "Surely the whole thing is clear as daylight. The man's caught red-handed. How he could be such a fool beats me!"

But Japp was looking attentively at Poirot.

"Hold your fire, Summerhaye," he remarked jocularly. "Me and Moosier here have met before—and there's no man's judgment I'd sooner take than his. If I'm not greatly mistaken, he's got something up his sleeve. Isn't that so, moosier?"

Poirot smiled.

"I have drawn certain conclusions—yes."

Summerhaye was still looking rather sceptical, but Japp continued his scrutiny of Poirot.

"It's this way," he said, "so far, we've only seen the case from the outside. That's where the Yard's at a disadvantage in a case of this kind, where the murder's only out, so to speak, after the inquest. A lot depends on being on the spot first thing, and that's where Mr. Poirot's had the start of us. We shouldn't have been here as soon as this even, if it hadn't been for the fact that there was a smart doctor on the spot, who gave us the tip through the Coroner. But you've been on the spot from the first, and you may have picked up some little hints. From the evidence at the inquest, Mr. Inglethorp murdered his wife as sure as I stand here, and if anyone but you hinted the contrary I'd laugh in his face. I must say I was surprised the jury didn't bring it in Wilful Murder against him right off. I think they would have, if it hadn't been for the Coroner—he seemed to be holding them back."

"Perhaps, though, you have a warrant for his arrest in your pocket now," suggested Poirot.

A kind of wooden shutter of officialdom came down from Japp's expressive countenance.

"Perhaps I have, and perhaps I haven't," he remarked dryly.

Poirot looked at him thoughtfully.

"I am very anxious, Messieurs, that he should not be arrested."

"I dare say," observed Summerhaye sarcastically.

Japp was regarding Poirot with comical perplexity.

"Can't you go a little further, Mr. Poirot? A wink's as good as a nod—from you. You've been on the spot—and the Yard doesn't want to make any mistakes, you know."

Poirot nodded gravely.

"That is exactly what I thought. Well, I will tell you this. Use your warrant: Arrest Mr. Inglethorp. But it will bring you no kudos—the case against him will be dismissed at once! Comme ca!" And he snapped his fingers expressively.

Japp's face grew grave, though Summerhaye gave an incredulous snort.

As for me, I was literally dumb with astonishment. I could only conclude that Poirot was mad.

Japp had taken out a handkerchief, and was gently dabbing his brow.

"I daren't do it, Mr. Poirot. I'd take your word, but there's others over me who'll be asking what the devil I mean by it. Can't you give me a little more to go on?"

Poirot reflected a moment.

"It can be done," he said at last. "I admit I do not wish it. It forces my hand. I would have preferred to work in the dark just for the present, but what you say is very just—the word of a Belgian policeman, whose day is past, is not enough! And Alfred Inglethorp must not be arrested. That I have sworn, as my friend Hastings here knows. See, then, my good Japp, you go at once to Styles?"

"Well, in about half an hour. We're seeing the Coroner and the doctor first."

"Good. Call for me in passing—the last house in the village. I will go with you. At Styles, Mr. Inglethorp will give you, or if he refuses—as is probable—I will give you such proofs that shall satisfy you that the case against him could not possibly be sustained. Is that a bargain?"

"That's a bargain," said Japp heartily. "And, on behalf of the Yard, I'm much obliged to you, though I'm bound to confess I can't at present see the faintest possible loop-hole in the evidence, but you always were a marvel! So long, then, moosier."

The two detectives strode away, Summerhaye with an incredulous grin on his face.

"Well, my friend," cried Poirot, before I could get in a word, "what do you think? Mon Dieu! I had some warm moments in that court; I did not figure to myself that the man would be so pig-headed as to refuse to say anything at all. Decidedly, it was the policy of an imbecile."

"H'm! There are other explanations besides that of imbecility," I remarked. "For, if the case against him is true, how could he defend himself except by silence?"

"Why, in a thousand ingenious ways," cried Poirot. "See; say that it is I who have committed this murder, I can think of seven most plausible stories! Far more convincing than Mr. Inglethorp's stony denials!"

I could not help laughing.

"My dear Poirot, I am sure you are capable of thinking of seventy! But, seriously, in spite of what I heard you say to the detectives, you surely cannot still believe in the possibility of Alfred Inglethorp's innocence?"

CHAPTER VIII.

FRESH SUSPICIONS

There was a moment's stupefied silence. Japp, who was the least surprised of any of us, was the first to speak.

"My word," he cried, "you're the goods! And no mistake, Mr. Poirot! These witnesses of yours are all right, I suppose?"

"Voila! I have prepared a list of them—names and addresses. You must see them, of course. But you will find it all right."

"I'm sure of that." Japp lowered his voice. "I'm much obliged to you. A pretty mare's nest arresting him would have been." He turned to Inglethorp. "But, if you'll excuse me, sir, why couldn't you say all this at the inquest?"

"I will tell you why," interrupted Poirot. "There was a certain rumour——"

"A most malicious and utterly untrue one," interrupted Alfred Inglethorp in an agitated voice.

"And Mr. Inglethorp was anxious to have no scandal revived just at present. Am I right?"

"Quite right." Inglethorp nodded. "With my poor Emily not yet buried, can you wonder I was anxious that no more lying rumours should be started."

"Between you and me, sir," remarked Japp, "I'd sooner have any amount of rumours than be arrested for murder. And I venture to think your poor lady would have felt the same. And, if it hadn't been for Mr. Poirot here, arrested you would have been, as sure as eggs is eggs!"

"I was foolish, no doubt," murmured Inglethorp. "But you do not know, inspector, how I have been persecuted and maligned." And he shot a baleful glance at Evelyn Howard.

"Now, sir," said Japp, turning briskly to John, "I should like to see the lady's bedroom, please, and after that I'll have a little chat with the servants. Don't you bother about anything. Mr. Poirot, here, will show me the way."

As they all went out of the room, Poirot turned and made me a sign to follow him upstairs. There he caught me by the arm, and drew me aside.

"Quick, go to the other wing. Stand there—just this side of the baize door. Do not move till I come." Then, turning rapidly, he rejoined the two detectives.

I followed his instructions, taking up my position by the baize door, and wondering what on earth lay behind the request. Why was I to stand in this particular spot on guard? I looked thoughtfully down the corridor in front of me. An idea struck me. With the exception of Cynthia Murdoch's, every one's room was in this left wing. Had that anything to do with it? Was I to report who came or went? I stood faithfully at my post. The minutes passed. Nobody came. Nothing happened.

It must have been quite twenty minutes before Poirot rejoined me.

"You have not stirred?"

"No, I've stuck here like a rock. Nothing's happened."

"Ah!" Was he pleased, or disappointed? "You've seen nothing at all?"

"No."

"But you have probably heard something? A big bump—eh, mon ami?"

"No."

"Is it possible? Ah, but I am vexed with myself! I am not usually clumsy. I made but a slight gesture"—I know Poirot's gestures—"with the left hand, and over went the table by the bed!"

He looked so childishly vexed and crest-fallen that I hastened to console him.

"Never mind, old chap. What does it matter? Your triumph downstairs excited you. I can tell you, that was a surprise to us all. There must be more in this affair of Inglethorp's with Mrs. Raikes than we thought, to make him hold his tongue so persistently. What are you going to do now? Where are the Scotland Yard fellows?"

"Gone down to interview the servants. I showed them all our exhibits. I am disappointed in Japp. He has no method!"

"Hullo!" I said, looking out of the window. "Here's Dr. Bauerstein. I believe you're right about that man, Poirot. I don't like him."

"He is clever," observed Poirot meditatively.

"Oh, clever as the devil! I must say I was overjoyed to see him in the plight he was in on Tuesday. You never saw such a spectacle!" And I described the doctor's adventure. "He looked a regular scarecrow! Plastered with mud from head to foot."

"You saw him, then?"

"Yes. Of course, he didn't want to come in—it was just after dinner—but Mr. Inglethorp insisted."

"What?" Poirot caught me violently by the shoulders. "Was Dr. Bauerstein here on Tuesday evening? Here? And you never told me? Why did you not tell me? Why? Why?"

He appeared to be in an absolute frenzy.

"My dear Poirot," I expostulated, "I never thought it would interest you. I didn't know it was of any importance."

"Importance? It is of the first importance! So Dr. Bauerstein was here on Tuesday night—the night of the murder. Hastings, do you not see? That alters everything—everything!"

I had never seen him so upset. Loosening his hold of me, he mechanically straightened a pair of candlesticks, still murmuring to himself: "Yes, that alters everything—everything."

Suddenly he seemed to come to a decision.

"Allons!" he said. "We must act at once. Where is Mr. Cavendish?"

John was in the smoking-room. Poirot went straight to him.

"Mr. Cavendish, I have some important business in Tadminster. A new clue. May I take your motor?"

"Why, of course. Do you mean at once?"

"If you please."

John rang the bell, and ordered round the car. In another ten minutes, we were racing down the park and along the high road to Tadminster.

"Now, Poirot," I remarked resignedly, "perhaps you will tell me what all this is about?"

"Well, mon ami, a good deal you can guess for yourself. Of course you realize that, now Mr. Inglethorp is out of it, the whole position is greatly changed. We are face to face with an entirely new problem. We know now that there is one person who did not buy the poison. We have cleared away the manufactured clues. Now for the real ones. I have ascertained that anyone in the household, with the exception of Mrs. Cavendish, who was playing tennis with you, could have personated Mr. Inglethorp on Monday evening. In the same way, we have his statement that he put the coffee down in the hall. No one took much notice of that at the inquest—but now it has a very different significance. We must find out who did take that coffee to Mrs. Inglethorp eventually, or who passed through the hall whilst it was standing there. From your account, there are only two people whom we can positively say did not go near the coffee—Mrs. Cavendish, and Mademoiselle Cynthia."

"Yes, that is so." I felt an inexpressible lightening of the heart. Mary Cavendish could certainly not rest under suspicion.

"In clearing Alfred Inglethorp," continued Poirot, "I have been obliged to show my hand sooner than I intended. As long as I might be thought to be pursuing him, the criminal would be off his guard. Now, he will be doubly careful. Yes—doubly careful." He turned to me abruptly. "Tell me, Hastings, you yourself—have you no suspicions of anybody?"

I hesitated. To tell the truth, an idea, wild and extravagant in itself, had once or twice that morning flashed through my brain. I had rejected it as absurd, nevertheless it persisted.

"You couldn't call it a suspicion," I murmured. "It's so utterly foolish."

"Come now," urged Poirot encouragingly. "Do not fear. Speak your mind. You should always pay attention to your instincts."

"Well then," I blurted out, "it's absurd—but I suspect Miss Howard of not telling all she knows!"

"Miss Howard?"

"Yes—you'll laugh at me——"

"Not at all. Why should I?"

"I can't help feeling," I continued blunderingly; "that we've rather left her out of the possible suspects, simply on the strength of her having been away from the place. But, after all, she was only fifteen miles away. A car would do it in half an hour. Can we say positively that she was away from Styles on the night of the murder?"

"Yes, my friend," said Poirot unexpectedly, "we can. One of my first actions was to ring up the hospital where she was working."

"Well?"

"Well, I learnt that Miss Howard had been on afternoon duty on Tuesday, and that—a convoy coming in unexpectedly—she had kindly offered to remain on night duty, which offer was gratefully accepted. That disposes of that."

"Oh!" I said, rather nonplussed. "Really," I continued, "it's her extraordinary vehemence against Inglethorp that started me off suspecting her. I can't help feeling she'd do anything against him. And I had an idea she might know something about the destroying of the will. She might have burnt the new one, mistaking it for the earlier one in his favour. She is so terribly bitter against him."

"You consider her vehemence unnatural?"

"Y—es. She is so very violent. I wondered really whether she is quite sane on that point."

Poirot shook his head energetically.

"No, no, you are on a wrong tack there. There is nothing weak-minded or degenerate about Miss Howard. She is an excellent specimen of well-balanced English beef and brawn. She is sanity itself."

CHAPTER IX

DR. BAUERSTEIN

I HAD had no opportunity as yet of passing on Poirot's message to Lawrence. But now, as I strolled out on the lawn, still nursing a grudge against my friend's high-handedness, I saw Lawrence on the croquet lawn, aimlessly knocking a couple of very ancient balls about, with a still more ancient mallet.

It struck me that it would be a good opportunity to deliver my message. Otherwise, Poirot himself might relieve me of it. It was true that I did not quite gather its purport, but I flattered myself that by Lawrence's reply, and perhaps a little skillful cross-examination on my part, I should soon perceive its significance. Accordingly I accosted him.

"I've been looking for you," I remarked untruthfully.

"Have you?"

"Yes. The truth is, I've got a message for you—from Poirot."

"Yes?"

"He told me to wait until I was alone with you," I said, dropping my voice significantly, and watching him intently out of the corner of my eye. I have always been rather good at what is called, I believe, creating an atmosphere.

"Well?"

There was no change of expression in the dark melancholic face. Had he any idea of what I was about to say?

"This is the message." I dropped my voice still lower. " 'Find the extra coffee-cup, and you can rest in peace.' "

"What on earth does he mean?" Lawrence stared at me in quite unaffected astonishment.

"Don't you know?"

"Not in the least. Do you?"

I was compelled to shake my head.

"What extra coffee-cup?"

"I don't know."

"He'd better ask Dorcas, or one of the maids, if he wants to know about coffee-cups. It's their business, not mine. I don't know anything about the coffee-cups, except that we've got some that are never used, which are a perfect dream! Old Worcester. You're not a connoisseur, are you, Hastings?"

I shook my head.

"You miss a lot. A really perfect bit of old china—it's pure delight to handle it, or even to look at it."

"Well, what am I to tell Poirot?"

"Tell him I don't know what he's talking about. It's double Dutch to me."

"All right."

I was moving off towards the house again when he suddenly called me back.

"I say, what was the end of that message? Say it over again, will you?"

" 'Find the extra coffee-cup, and you can rest in peace.' Are you sure you don't know what it means?" I asked him earnestly.

He shook his head.

"No," he said musingly, "I don't. I—I wish I did."

The boom of the gong sounded from the house, and we went in together. Poirot had been asked by John to remain to lunch, and was already seated at the table.

By tacit consent, all mention of the tragedy was barred. We conversed on the war, and other outside topics. But after the cheese and biscuits had been handed round, and Dorcas had left the room, Poirot suddenly leant forward to Mrs. Cavendish.

"Pardon me, madame, for recalling unpleasant memories, but I have a little idea"—Poirot's "little ideas" were becoming a perfect byword—"and would like to ask one or two questions."

"Of me? Certainly."

"You are too amiable, madame. What I want to ask is this: the door leading into Mrs. Inglethorp's room from that of Mademoiselle Cynthia, it was bolted, you say?"

"Certainly it was bolted," replied Mary Cavendish, rather surprised. "I said so at the inquest."

"Bolted?"

"Yes." She looked perplexed.

"I mean," explained Poirot, "you are sure it was bolted, and not merely locked?"

"Oh, I see what you mean. No, I don't know. I said bolted, meaning that it was fastened, and I could not open it, but I believe all the doors were found bolted on the inside."

"Still, as far as you are concerned, the door might equally well have been locked?"

"Oh, yes."

"You yourself did not happen to notice, madame, when you entered Mrs. Inglethorp's room, whether that door was bolted or not?"

"I—I believe it was."

"But you did not see it?"

"No. I—never looked."

"But I did," interrupted Lawrence suddenly. "I happened to notice that it was bolted."

"Ah, that settles it." And Poirot looked crestfallen.

I could not help rejoicing that, for once, one of his "little ideas" had come to naught.

After lunch Poirot begged me to accompany him home. I consented rather stiffly.

"You are annoyed, is it not so?" he asked anxiously, as we walked through the park.

"Not at all," I said coldly.

"That is well. That lifts a great load from my mind."

This was not quite what I had intended. I had hoped that he would have observed the stiffness of my manner. Still, the fervour of his words went towards the appeasing of my just displeasure. I thawed.

"I gave Lawrence your message," I said.

"And what did he say? He was entirely puzzled?"

"Yes. I am quite sure he had no idea of what you meant."

I had expected Poirot to be disappointed; but, to my surprise, he replied that that was as he had thought, and that he was very glad. My pride forbade me to ask any questions.

Poirot switched off on another tack.

"Mademoiselle Cynthia was not at lunch to-day? How was that?"

"She is at the hospital again. She resumed work to-day."

"Ah, she is an industrious little demoiselle. And pretty too. She is like pictures I have seen in Italy. I would rather like to see that dispensary of hers. Do you think she would show it to me?"

"I am sure she would be delighted. It's an interesting little place."

"Does she go there every day?"

"She has all Wednesdays off, and comes back to lunch on Saturdays. Those are her only times off."

"I will remember. Women are doing great work nowadays, and Mademoiselle Cynthia is clever—oh, yes, she has brains, that little one."

"Yes. I believe she has passed quite a stiff exam."

"Without doubt. After all, it is very responsible work. I suppose they have very strong poisons there?"

"Yes, she showed them to us. They are kept locked up in a little cupboard. I believe they have to be very careful. They always take out the key before leaving the room."

"Indeed. It is near the window, this cupboard?"

"No, right the other side of the room. Why?"

Poirot shrugged his shoulders.

"I wondered. That is all. Will you come in?"

We had reached the cottage.

"No. I think I'll be getting back. I shall go round the long way through the woods."

The woods round Styles were very beautiful. After the walk across the open park, it was pleasant to saunter lazily through the cool glades. There was hardly a breath of wind, the very chirp of the birds was faint and subdued. I strolled on a little way, and finally flung myself down at the foot of a grand old beech-tree. My thoughts of mankind were kindly and charitable. I even forgave Poirot for his absurd secrecy. In fact, I was at peace with the world. Then I yawned.

CHAPTER X.

THE ARREST

To my extreme annoyance, Poirot was not in, and the old Belgian who answered my knock informed me that he believed he had gone to London.

I was dumbfounded. What on earth could Poirot be doing in London! Was it a sudden decision on his part, or had he already made up his mind when he parted from me a few hours earlier?

I retraced my steps to Styles in some annoyance. With Poirot away, I was uncertain how to act. Had he foreseen this arrest? Had he not, in all probability, been the cause of it? Those questions I could not resolve. But in the meantime what was I to do? Should I announce the arrest openly at Styles, or not? Though I did not acknowledge it to myself, the thought of Mary Cavendish was weighing on me. Would it not be a terrible shock to her? For the moment, I set aside utterly any suspicions of her. She could not be implicated—otherwise I should have heard some hint of it.

Of course, there was no possibility of being able permanently to conceal Dr. Bauerstein's arrest from her. It would be announced in every newspaper on the morrow. Still, I shrank from blurting it out. If only Poirot had been accessible, I could have asked his advice. What possessed him to go posting off to London in this unaccountable way?

In spite of myself, my opinion of his sagacity was immeasurably heightened. I would never have dreamt of suspecting the doctor, had not Poirot put it into my head. Yes, decidedly, the little man was clever.

After some reflecting, I decided to take John into my confidence, and leave him to make the matter public or not, as he thought fit.

He gave vent to a prodigious whistle, as I imparted the news.

"Great Scot! You were right, then. I couldn't believe it at the time."

"No, it is astonishing until you get used to the idea, and see how it makes everything fit in. Now, what are we to do? Of course, it will be generally known to-morrow."

John reflected.

"Never mind," he said at last, "we won't say anything at present. There is no need. As you say, it will be known soon enough."

But to my intense surprise, on getting down early the next morning, and eagerly opening the newspapers, there was not a word about the arrest! There was a column of mere padding about "The Styles Poisoning Case," but nothing further. It was rather inexplicable, but I supposed that, for some reason or other, Japp wished to keep it out of the papers. It worried me just a little, for it suggested the possibility that there might be further arrests to come.

After breakfast, I decided to go down to the village, and see if Poirot had returned yet; but, before I could start, a well-known face blocked one of the windows, and the well-known voice said:

"Bon jour, mon ami!"

"Poirot," I exclaimed, with relief, and seizing him by both hands, I dragged him into the room. "I was never so glad to see anyone. Listen, I have said nothing to anybody but John. Is that right?"

"My friend," replied Poirot, "I do not know what you are talking about."

"Dr. Bauerstein's arrest, of course," I answered impatiently.

"Is Bauerstein arrested, then?"

"Did you not know it?"

"Not the least in the world." But, pausing a moment, he added: "Still, it does not surprise me. After all, we are only four miles from the coast."

"The coast?" I asked, puzzled. "What has that got to do with it?"

Poirot shrugged his shoulders.

"Surely, it is obvious!"

"Not to me. No doubt I am very dense, but I cannot see what the proximity of the coast has got to do with the murder of Mrs. Inglethorp."

"Nothing at all, of course," replied Poirot, smiling. "But we were speaking of the arrest of Dr. Bauerstein."

"Well, he is arrested for the murder of Mrs. Inglethorp——"

"What?" cried Poirot, in apparently lively astonishment. "Dr. Bauerstein arrested for the murder of Mrs. Inglethorp?"

"Yes."

"Impossible! That would be too good a farce! Who told you that, my friend?"

"Well, no one exactly told me," I confessed. "But he is arrested."

"Oh, yes, very likely. But for espionage, mon ami."

"Espionage?" I gasped.

"Precisely."

"Not for poisoning Mrs. Inglethorp?"

"Not unless our friend Japp has taken leave of his senses," replied Poirot placidly.

"But—but I thought you thought so too?"

Poirot gave me one look, which conveyed a wondering pity, and his full sense of the utter absurdity of such an idea.

"Do you mean to say," I asked, slowly adapting myself to the new idea, "that Dr. Bauerstein is a spy?"

Poirot nodded.

"Have you never suspected it?"

"It never entered my head."

"It did not strike you as peculiar that a famous London doctor should bury himself in a little village like this, and should be in the habit of walking about at all hours of the night, fully dressed?"

"No," I confessed, "I never thought of such a thing."

"He is, of course, a German by birth," said Poirot thoughtfully, "though he has practiced so long in this country that nobody thinks of him as anything but an Englishman. He was naturalized about fifteen years ago. A very clever man—a Jew, of course."

"The blackguard!" I cried indignantly.

"Not at all. He is, on the contrary, a patriot. Think what he stands to lose. I admire the man myself."

But I could not look at it in Poirot's philosophical way.

"And this is the man with whom Mrs. Cavendish has been wandering about all over the country!" I cried indignantly.

"Yes. I should fancy he had found her very useful," remarked Poirot. "So long as gossip busied itself in coupling their names together, any other vagaries of the doctor's passed unobserved."

"Then you think he never really cared for her?" I asked eagerly—rather too eagerly, perhaps, under the circumstances.

"That, of course, I cannot say, but—shall I tell you my own private opinion, Hastings?"

"Yes."

"Well, it is this: that Mrs. Cavendish does not care, and never has cared one little jot about Dr. Bauerstein!"

"Do you really think so?" I could not disguise my pleasure.

"I am quite sure of it. And I will tell you why."

"Yes?"

"Because she cares for some one else, mon ami."

"Oh!" What did he mean? In spite of myself, an agreeable warmth spread over me. I am not a vain man where women are concerned, but I remembered certain evidences, too lightly thought of at the time, perhaps, but which certainly seemed to indicate——

My pleasing thoughts were interrupted by the sudden entrance of Miss Howard. She glanced round hastily to make sure there was no one else in the room, and quickly produced an old sheet of brown paper. This she handed to Poirot, murmuring as she did so the cryptic words:

"On top of the wardrobe." Then she hurriedly left the room.

Poirot unfolded the sheet of paper eagerly, and uttered an exclamation of satisfaction. He spread it out on the table.

"Come here, Hastings. Now tell me, what is that initial—J. or L.?"

It was a medium sized sheet of paper, rather dusty, as though it had lain by for some time. But it was the label that was attracting Poirot's attention. At the top, it bore the printed stamp of Messrs. Parkson's, the well-known theatrical costumiers, and it was addressed to "—(the debatable initial) Cavendish, Esq., Styles Court, Styles St. Mary, Essex."

"It might be T., or it might be L.," I said, after studying the thing for a minute or two. "It certainly isn't a J."

"Good," replied Poirot, folding up the paper again. "I, also, am of your way of thinking. It is an L., depend upon it!"

"Where did it come from?" I asked curiously. "Is it important?"

"Moderately so. It confirms a surmise of mine. Having deduced its existence, I set Miss Howard to search for it, and, as you see, she has been successful."

"What did she mean by 'On the top of the wardrobe'?"

"She meant," replied Poirot promptly, "that she found it on top of a wardrobe."

"A funny place for a piece of brown paper," I mused.

"Not at all. The top of a wardrobe is an excellent place for brown paper and cardboard boxes. I have kept them there myself. Neatly arranged, there is nothing to offend the eye."

"Poirot," I asked earnestly, "have you made up your mind about this crime?"

"Yes—that is to say, I believe I know how it was committed."

CHAPTER XI.

THE CASE FOR THE PROSECUTION

The trial of John Cavendish for the murder of his stepmother took place two months later.

Of the intervening weeks I will say little, but my admiration and sympathy went out unfeignedly to Mary Cavendish. She ranged herself passionately on her husband's side, scorning the mere idea of his guilt, and fought for him tooth and nail.

I expressed my admiration to Poirot, and he nodded thoughtfully.

"Yes, she is of those women who show at their best in adversity. It brings out all that is sweetest and truest in them. Her pride and her jealousy have—"

"Jealousy?" I queried.

"Yes. Have you not realized that she is an unusually jealous woman? As I was saying, her pride and jealousy have been laid aside. She thinks of nothing but her husband, and the terrible fate that is hanging over him."

He spoke very feelingly, and I looked at him earnestly, remembering that last afternoon, when he had been deliberating whether or not to speak. With his tenderness for "a woman's happiness," I felt glad that the decision had been taken out of his hands.

"Even now," I said, "I can hardly believe it. You see, up to the very last minute, I thought it was Lawrence!"

Poirot grinned.

"I know you did."

"But John! My old friend John!"

"Every murderer is probably somebody's old friend," observed Poirot philosophically. "You cannot mix up sentiment and reason."

"I must say I think you might have given me a hint."

"Perhaps, mon ami, I did not do so, just because he was your old friend."

I was rather disconcerted by this, remembering how I had busily passed on to John what I believed to be Poirot's views concerning Bauerstein. He, by the way, had been acquitted of the charge brought against him. Nevertheless, although he had been too clever for them this time, and the charge of espionage could not be brought home to him, his wings were pretty well clipped for the future.

I asked Poirot whether he thought John would be condemned. To my intense surprise, he replied that, on the contrary, he was extremely likely to be acquitted.

"But, Poirot—" I protested.

"Oh, my friend, have I not said to you all along that I have no proofs. It is one thing to know that a man is guilty, it is quite another matter to prove him so. And, in this case, there is terribly little evidence. That is the whole trouble. I, Hercule Poirot, know, but I lack the last link in my chain. And unless I can find that missing link—" He shook his head gravely.

"When did you first suspect John Cavendish?" I asked, after a minute or two.

"Did you not suspect him at all?"

"No, indeed."

"Not after that fragment of conversation you overheard between Mrs. Cavendish and her mother-in-law, and her subsequent lack of frankness at the inquest?"

"No."

"Did you not put two and two together, and reflect that if it was not Alfred Inglethorp who was quarrelling with his wife—and you remember, he strenuously denied it at the inquest—it must be either Lawrence or John. Now, if it was Lawrence, Mary Cavendish's conduct was just as inexplicable. But if, on the other hand, it was John, the whole thing was explained quite naturally."

"So," I cried, a light breaking in upon me, "it was John who quarrelled with his mother that afternoon?"

"Exactly."

"And you have known this all along?"

"Certainly. Mrs. Cavendish's behaviour could only be explained that way."

"And yet you say he may be acquitted?"

Poirot shrugged his shoulders.

"Certainly I do. At the police court proceedings, we shall hear the case for the prosecution, but in all probability his solicitors will advise him to reserve his defence. That will be sprung upon us at the trial. And—ah, by the way, I have a word of caution to give you, my friend. I must not appear in the case."

"What?"

"No. Officially, I have nothing to do with it. Until I have found that last link in my chain, I must remain behind the scenes. Mrs. Cavendish must think I am working for her husband, not against him."

"I say, that's playing it a bit low down," I protested.

"Not at all. We have to deal with a most clever and unscrupulous man, and we must use any means in our power—otherwise he will slip through our fingers. That is why I have been careful to remain in the background. All the discoveries have been made by Japp, and Japp will take all the credit. If I am called upon to give evidence at all"—he smiled broadly—"it will probably be as a witness for the defence."

I could hardly believe my ears.

"It is quite en regle," continued Poirot. "Strangely enough, I can give evidence that will demolish one contention of the prosecution."

"Which one?"

"The one that relates to the destruction of the will. John Cavendish did not destroy that will."

Poirot was a true prophet. I will not go into the details of the police court proceedings, as it involves many tiresome repetitions. I will merely state baldly that John Cavendish reserved his defence, and was duly committed for trial.

September found us all in London. Mary took a house in Kensington, Poirot being included in the family party.

I myself had been given a job at the War Office, so was able to see them continually.

As the weeks went by, the state of Poirot's nerves grew worse and worse. That "last link" he talked about was still lacking. Privately, I hoped it might remain so, for what happiness could there be for Mary, if John were not acquitted?

On September 15th John Cavendish appeared in the dock at the Old Bailey, charged with "The Wilful Murder of Emily Agnes Inglethorp," and pleaded "Not Guilty."

Sir Ernest Heavywether, the famous K. C., had been engaged to defend him.

Mr. Philips, K. C., opened the case for the Crown.

The murder, he said, was a most premeditated and cold-blooded one. It was neither more nor less than the deliberate poisoning of a fond and trusting woman by the stepson to whom she had been more than a mother. Ever since his boyhood, she had supported him. He and his wife had lived at Styles Court in every luxury, surrounded by her care and attention. She had been their kind and generous benefactress.

He proposed to call witnesses to show how the prisoner, a profligate and spendthrift, had been at the end of his financial tether, and had also been carrying on an intrigue with a certain Mrs. Raikes, a neighbouring farmer's wife. This having come to his stepmother's ears, she taxed him with it on the afternoon before her death, and a quarrel ensued, part of which was overheard. On the previous day, the prisoner had purchased strychnine at the village chemist's shop, wearing a disguise by means of which he hoped to throw the onus of the crime upon another man—to wit, Mrs. Inglethorp's husband, of whom he had been bitterly jealous. Luckily for Mr. Inglethorp, he had been able to produce an unimpeachable alibi.

On the afternoon of July 17th, continued Counsel, immediately after the quarrel with her son, Mrs. Inglethorp made a new will. This will was found destroyed in the grate of her bedroom the following morning, but evidence had come to light which showed that it had been drawn up in favour of her husband. Deceased had already made a will in his favour before her marriage, but—and Mr. Philips wagged an expressive forefinger—the prisoner was not aware of that. What had induced the deceased to make a fresh will, with the old one still extant, he could not say. She was an old lady, and might possibly have forgotten the former one; or—this seemed to him more likely—she may have had an idea that it was revoked by her marriage, as there had been some conversation on the subject. Ladies were not always very well versed in legal knowledge. She had, about a year before, executed a will in favour of the prisoner. He would call evidence to show that it was the prisoner who ultimately handed his stepmother her coffee on the fatal night. Later in the evening, he had sought admission to her room, on which occasion, no doubt, he found an opportunity of destroying the will which, as far as he knew, would render the one in his favour valid.

The prisoner had been arrested in consequence of the discovery, in his room, by Detective Inspector Japp—a most brilliant officer—of the identical phial of strychnine which had been sold at the village chemist's to the supposed Mr. Inglethorp on the day before the murder. It would be for the jury to decide whether or not these damning facts constituted an overwhelming proof of the prisoner's guilt.

And, subtly implying that a jury which did not so decide, was quite unthinkable, Mr. Philips sat down and wiped his forehead.

The first witnesses for the prosecution were mostly those who had been called at the inquest, the medical evidence being again taken first.

Sir Ernest Heavywether, who was famous all over England for the unscrupulous manner in which he bullied witnesses, only asked two questions.

"I take it, Dr. Bauerstein, that strychnine, as a drug, acts quickly?"

"Yes."

"And that you are unable to account for the delay in this case?"

"Yes."

"Thank you."

Mr. Mace identified the phial handed him by Counsel as that sold by him to "Mr. Inglethorp." Pressed, he admitted that he only knew Mr. Inglethorp by sight. He had never spoken to him. The witness was not cross-examined.

Alfred Inglethorp was called, and denied having purchased the poison. He also denied having quarrelled with his wife. Various witnesses testified to the accuracy of these statements.

The gardeners' evidence, as to the witnessing of the will was taken, and then Dorcas was called.

Dorcas, faithful to her "young gentlemen," denied strenuously that it could have been John's voice she heard, and resolutely declared, in the teeth of everything, that it was Mr. Inglethorp who had been in the boudoir with her mistress. A rather wistful smile passed across the face of the prisoner in the dock. He knew only too well how useless her gallant defiance was, since it was not the object of the defence to deny this point. Mrs. Cavendish, of course, could not be called upon to give evidence against her husband.

After various questions on other matters, Mr. Philips asked:

"In the month of June last, do you remember a parcel arriving for Mr. Lawrence Cavendish from Parkson's?"

Dorcas shook her head.

"I don't remember, sir. It may have done, but Mr. Lawrence was away from home part of June."

"In the event of a parcel arriving for him whilst he was away, what would be done with it?"

"It would either be put in his room or sent on after him."

"By you?"

CHAPTER XII

THE LAST LINK

POIROT'S abrupt departure had intrigued us all greatly. Sunday morning wore away, and still he did not reappear. But about three o'clock a ferocious and prolonged hooting outside drove us to the window, to see Poirot alighting from a car, accompanied by Japp and Summerhaye. The little man was transformed. He radiated an absurd complacency. He bowed with exaggerated respect to Mary Cavendish.

"Madame, I have your permission to hold a little reunion in the salon? It is necessary for every one to attend."

Mary smiled sadly.

"You know, Monsieur Poirot, that you have carte blanche in every way."

"You are too amiable, madame."

Still beaming, Poirot marshalled us all into the drawing-room, bringing forward chairs as he did so.

"Miss Howard—here. Mademoiselle Cynthia. Monsieur Lawrence. The good Dorcas. And Annie. Bien! We must delay our proceedings a few minutes until Mr. Inglethorp arrives. I have sent him a note."

Miss Howard rose immediately from her seat.

"If that man comes into the house, I leave it!"

"No, no!" Poirot went up to her and pleaded in a low voice.

Finally Miss Howard consented to return to her chair. A few minutes later Alfred Inglethorp entered the room.

The company once assembled, Poirot rose from his seat with the air of a popular lecturer, and bowed politely to his audience.

"Messieurs, mesdames, as you all know, I was called in by Monsieur John Cavendish to investigate this case. I at once examined the bedroom of the deceased which, by the advice of the doctors, had been kept locked, and was consequently exactly as it had been when the tragedy occurred. I found: first, a fragment of green material; second, a stain on the carpet near the window, still damp; thirdly, an empty box of bromide powders.

"To take the fragment of green material first, I found it caught in the bolt of the communicating door between that room and the adjoining one occupied by Mademoiselle Cynthia. I handed the fragment over to the police who did not consider it of much importance. Nor did they recognize it for what it was—a piece torn from a green land armlet."

There was a little stir of excitement.

"Now there was only one person at Styles who worked on the land—Mrs. Cavendish. Therefore it must have been Mrs. Cavendish who entered the deceased's room through the door communicating with Mademoiselle Cynthia's room."

"But that door was bolted on the inside!" I cried.

"When I examined the room, yes. But in the first place we have only her word for it, since it was she who tried that particular door and reported it fastened. In the ensuing confusion she would have had ample opportunity to shoot the bolt across. I took an early opportunity of verifying my conjectures. To begin with, the fragment corresponds exactly with a tear in Mrs. Cavendish's armlet. Also, at the inquest, Mrs. Cavendish declared that she had heard, from her own room, the fall of the table by the bed. I took an early opportunity of testing that statement by stationing my friend Monsieur Hastings in the left wing of the building, just outside Mrs. Cavendish's door. I myself, in company with the police, went to the deceased's room, and whilst there I, apparently accidentally, knocked over the table in question, but found that, as I had expected, Monsieur Hastings had heard no sound at all. This confirmed my belief that Mrs. Cavendish was not speaking the truth when she declared that she had been dressing in her room at the time of the tragedy. In fact, I was convinced that, far from having been in her own room, Mrs. Cavendish was actually in the deceased's room when the alarm was given."

I shot a quick glance at Mary. She was very pale, but smiling.

"I proceeded to reason on that assumption. Mrs. Cavendish is in her mother-in-law's room. We will say that she is seeking for something and has not yet found it. Suddenly Mrs. Inglethorp awakens and is seized with an alarming paroxysm. She flings out her arm, overturning the bed table, and then pulls desperately at the bell. Mrs. Cavendish, startled, drops her candle, scattering the grease on the carpet. She picks it up, and retreats quickly to Mademoiselle Cynthia's room, closing the door behind her. She hurries out into the passage, for the servants must not find her where she is. But it is too late! Already footsteps are echoing along the gallery which connects the two wings. What can she do? Quick as thought, she hurries back to the young girl's room, and starts shaking her awake. The hastily aroused household come trooping down the passage. They are all busily battering at Mrs. Inglethorp's door. It occurs to nobody that Mrs. Cavendish has not arrived with the rest, but—and this is significant—I can find no one who saw her come from the other wing." He looked at Mary Cavendish. "Am I right, madame?"

She bowed her head.

CHAPTER XIII.

POIROT EXPLAINS

"Poirot, you old villain," I said, "I've half a mind to strangle you! What do you mean by deceiving me as you have done?"

We were sitting in the library. Several hectic days lay behind us. In the room below, John and Mary were together once more, while Alfred Inglethorp and Miss Howard were in custody. Now at last, I had Poirot to myself, and could relieve my still burning curiosity.

Poirot did not answer me for a moment, but at last he said:

"I did not deceive you, mon ami. At most, I permitted you to deceive yourself."

"Yes, but why?"

"Well, it is difficult to explain. You see, my friend, you have a nature so honest, and a countenance so transparent, that—enfin, to conceal your feelings is impossible! If I had told you my ideas, the very first time you saw Mr. Alfred Inglethorp that astute gentleman would have—in your so expressive idiom—'smelt a rat'! And then, bon jour to our chances of catching him!"

"I think that I have more diplomacy than you give me credit for."

"My friend," besought Poirot, "I implore you, do not enrage yourself! Your help has been of the most invaluable. It is but the extremely beautiful nature that you have, which made me pause."

"Well," I grumbled, a little mollified. "I still think you might have given me a hint."

"But I did, my friend. Several hints. You would not take them. Think now, did I ever say to you that I believed John Cavendish guilty? Did I not, on the contrary, tell you that he would almost certainly be acquitted?"

"Yes, but——"

"And did I not immediately afterwards speak of the difficulty of bringing the murderer to justice? Was it not plain to you that I was speaking of two entirely different persons?"

"No," I said, "it was not plain to me!"

"Then again," continued Poirot, "at the beginning, did I not repeat to you several times that I didn't want Mr. Inglethorp arrested now? That should have conveyed something to you."

"Do you mean to say you suspected him as long ago as that?"

"Yes. To begin with, whoever else might benefit by Mrs. Inglethorp's death, her husband would benefit the most. There was no getting away from that. When I went up to Styles with you that first day, I had no idea as to how the crime had been committed, but from what I knew of Mr. Inglethorp I fancied that it would be very hard to find anything to connect him with it. When I arrived at the chateau, I realized at once that it was Mrs. Inglethorp who had burnt the will; and there, by the way, you cannot complain, my friend, for I tried my best to force on you the significance of that bedroom fire in midsummer."

"Yes, yes," I said impatiently. "Go on."

"Well, my friend, as I say, my views as to Mr. Inglethorp's guilt were very much shaken. There was, in fact, so much evidence against him that I was inclined to believe that he had not done it."

"When did you change your mind?"

"When I found that the more efforts I made to clear him, the more efforts he made to get himself arrested. Then, when I discovered that Inglethorp had nothing to do with Mrs. Raikes and that in fact it was John Cavendish who was interested in that quarter, I was quite sure."

"But why?"

"Simply this. If it had been Inglethorp who was carrying on an intrigue with Mrs. Raikes, his silence was perfectly comprehensible. But, when I discovered that it was known all over the village that it was John who was attracted by the farmer's pretty wife, his silence bore quite a different interpretation. It was nonsense to pretend that he was afraid of the scandal, as no possible scandal could attach to him. This attitude of his gave me furiously to think, and I was slowly forced to the conclusion that Alfred Inglethorp wanted to be arrested. Eh bien! from that moment, I was equally determined that he should not be arrested."

"Wait a minute. I don't see why he wished to be arrested?"

"Because, mon ami, it is the law of your country that a man once acquitted can never be tried again for the same offence. Aha! but it was clever—his idea! Assuredly, he is a man of method. See here, he knew that in his position he was bound to be suspected, so he conceived the exceedingly clever idea of preparing a lot of manufactured evidence against himself. He wished to be arrested. He would then produce his irreproachable alibi—and, hey presto, he was safe for life!"

"But I still don't see how he managed to prove his alibi, and yet go to the chemist's shop?"

Poirot stared at me in surprise.

"Is it possible? My poor friend! You have not yet realized that it was Miss Howard who went to the chemist's shop?"

"Miss Howard?"

"But, certainly. Who else? It was most easy for her. She is of a good height, her voice is deep and manly; moreover, remember, she and Inglethorp are cousins, and there is a distinct resemblance between them, especially in their gait and bearing. It was simplicity itself. They are a clever pair!"

"I am still a little fogged as to how exactly the bromide business was done," I remarked.

"Bon! I will reconstruct for you as far as possible. I am inclined to think that Miss Howard was the master mind in that affair. You remember her once mentioning that her father was a doctor? Possibly she dispensed his medicines for him, or she may have taken the idea from one of the many books lying about when Mademoiselle Cynthia was studying for her exam. Anyway, she was familiar with the fact that the addition of a bromide to a mixture containing strychnine would cause the precipitation of the latter. Probably the idea came to her quite suddenly. Mrs. Inglethorp had a box of bromide powders, which she occasionally took at night. What could be easier than quietly to dissolve one or more of those powders in Mrs. Inglethorp's large sized bottle of medicine when it came from Coot's? The risk is practically nil. The tragedy will not take place until nearly a fortnight later. If anyone has seen either of them touching the medicine, they will have forgotten it by that time. Miss Howard will have engineered her quarrel, and departed from the house. The lapse of time, and her absence, will defeat all suspicion. Yes, it was a clever idea! If they had left it alone, it is possible the crime might never have been brought home to them. But they were not satisfied. They tried to be too clever—and that was their undoing."

Poirot puffed at his tiny cigarette, his eyes fixed on the ceiling.

"They arranged a plan to throw suspicion on John Cavendish, by buying strychnine at the village chemist's, and signing the register in his hand-writing.

"On Monday Mrs. Inglethorp will take the last dose of her medicine. On Monday, therefore, at six o'clock, Alfred Inglethorp arranges to be seen by a number of people at a spot far removed from the village. Miss Howard has previously made up a cock and bull story about him and Mrs. Raikes to account for his holding his tongue afterwards. At six o'clock, Miss Howard, disguised as Alfred Inglethorp, enters the chemist's shop, with her story about a dog, obtains the strychnine, and writes the name of Alfred Inglethorp in John's handwriting, which she had previously studied carefully.

"But, as it will never do if John, too, can prove an alibi, she writes him an anonymous note—still copying his hand-writing —which takes him to a remote spot where it is exceedingly unlikely that anyone will see him.
