Caroline nodded, and went with Ursula out of the room.

But Caroline silenced her protests with a firm hand.

"Nonsense. You're in my hands for the time being. You'll stay here for the present, anyway -- eh, M. Poirot?"

"It will be the best plan," agreed the little Belgian. "This evening I shall want mademoiselle -- I beg her pardon, madame -- to attend my little reunion. Nine o'clock at my house. It is most necessary that she should be there."

"I ought to go back to Fernly," said Ursula uncertainly.

Poirot nodded. "Yes, that is so. But it was to be expected, was it not?"

The door shut behind them. Poirot dropped down into a chair again.

I looked at him, slightly puzzled by the remark. He was leaning back in the chair, his eyes half closed, the tips of his fingers just touching each other. Suddenly he sighed and shook his head.

"And now," said Caroline, rising, "that child is coming upstairs to lie down. Don't you worry, my dear. M. Poirot will do everything he can for you -- be sure of that."

"So far, so good," he said. "Things are straightening themselves out."

"They're getting to look blacker and blacker against Ralph Paton," I observed gloomily.

I gave a slightly embarrassed cough.

"What is it?" I asked.

"It is that there are moments when a great longing for my friend Hastings comes over me. That is the friend of whom I spoke to you -- the one who resides now in the Argentine. Always, when I have had a big case, he has been by my side. And he has helped me -- yes, often he has helped me. For he had a knack, that one, of stumbling over the truth unawares -- without noticing it himself, bien entendu. At times, he has said something particularly foolish, and behold that foolish remark has revealed the truth to me! And then, too, it was his practice to keep a written record of the cases that proved interesting."

Poirot sat upright in his chair. His eyes sparkled.

"But yes? What is it that you would say?"

"Well, as a matter of fact, I've read some of Captain Hastings's narratives, and I thought, why not try my hand at something of the same kind. Seemed a pity not to unique opportunity -- probably the only time I'll be mixed up with anything of this kind." I felt myself getting hotter and hotter, and more and more incoherent, as I floundered through the above speech.

"As far as that goes," I began, and then stopped.

"But this is magnificent -- you have then written down your impressions of the case as you went along?"

Poirot sprang from his chair. I had a moment's terror that he was going to embrace me French fashion, but mercifully he refrained.

"Epatant!" cried Poirot. "Let me see them -- this instant."

I nodded.

I was not quite prepared for such a sudden demand. I racked my brains to remember certain details.

"I hope you won't mind," I stammered. "I may have been a little -- er -- personal now and then."

Still somewhat doubtful, I rummaged in the drawers of my desk and produced an untidy pile of manuscript which I handed over to him. With an eye on possible publication in the future, I had divided the work into chapters, and the night before I had brought it up to date with an account of Miss Russell's visit. Poirot had therefore twenty chapters.

"Oh! I comprehend perfectly; you have referred to me as comic -- as, perhaps, ridiculous now and then? It matters not at all. Hastings, he also was not always polite. Me, I have the mind above such trivialities."

"I hope, James," said my sister, "that you've been careful in what you say about me in it?" My jaw dropped. I had not been careful at all.

I went into the workshop. Poirot was sitting by the window. The manuscript lay neatly piled on a chair beside him. He laid his hand on it and spoke.

I left him with them.

I was obliged to go out to a case at some distance away and it was past eight o'clock when I got back, to be greeted with a plate of hot dinner on a tray, and the announcement that Poirot and my sister had supped together at half-past seven, and that the former had then gone to my workshop to finish his reading of the manuscript.

"Not so did Hastings write," continued my friend. "On every page, many, many times was the word "I." What he thought -- what he did. But you -- you have kept your personality in the background; only once or twice does it obtrude -- in scenes of home life, shall we say?" I blushed a little before the twinkle of his eye.

"Not that it matters very much," said Caroline, reading my expression correctly. "M. Poirot will know what to think. He understands me much better than you do."

"Eh bien," he said, "I congratulate you -- on your modesty!"

"Oh!" I said, rather taken aback.

"And on your reticence," he added.

I said "Oh!" again.

"What do you really think of the stuff?" I asked nervously.

"Yes." Poirot laid his jesting manner aside.

"You want my candid opinion?"

"I see that you do not," said Poirot drily. "Not yet do you appreciate Hercule Poirot at his true worth."

Caroline was in the hall. I think she hoped that she might be invited to accompany us. Poirot dealt with the situation tactfully.

"Yes. I may say that it has helped me considerably. Come, we must go over to my house and set the stage for my little performance."

"You really believe that?" I said incredulously.

"And it has helped you?"

"A very meticulous and accurate account," he said kindly. "You have recorded all the facts faithfully and exactly though you have shown yourself becomingly reticent as to your own share in them."

At that minute Ursula came down the staircase.

"I should much like to have had you present, mademoiselle," he said regretfully, "but at this juncture it would not be wise. See you, all these people tonight are suspects. Amongst them, I shall find the person who killed Mr Ackroyd."

We went off, leaving Caroline rather like a dog who has been refused a walk, standing on the front door step gazing after us.

"You are ready, my child?" said Poirot. "That is good. We will go to my house together. Mademoiselle Caroline, believe me, I do everything possible to render you service. Good-evening."

Ursula and I watched him. Presently a bell was heard.

The sitting-room at The Larches had been got ready. On the table were various siropes and glasses. Also a plate of biscuits.

Several chairs had been brought in from the other room.

Poirot ran to and fro rearranging things. Pulling out a chair here, altering the position of a lamp there, occasionally stooping to straighten one of the mats that covered the floor. He was specially fussing over the lighting. The lamps were arranged in. such a way as to throw a clear light on the side of the room where the chairs were grouped, at the same time leaving the other end of the room, where I presumed Poirot himself would sit, in a dim twilight.

"They arrive," said Poirot. "Good, all is in readiness."

The secretary was debonair as ever.

The door opened and the party from Femly filed in. Poirot went forward and greeted Mrs Ackroyd and Flora.

"It is most good of you to come," he said. "And Major Blunt and Mr Raymond."

A little shriek burst from Mrs Ackroyd. "Ralph! Married! Last March! Oh! but it's absurd. How could he be?" She stared at Ursula as though she had never seen her before. "Married to Bourne?" she said. "Really, M. Poirot, I don't believe you."

"I have read of it, yes," admitted Poirot. "But me, I am oldfashioned. I use the old methods. I work only with the little grey cells. Now let us begin -- but first I have an announcement to make to you all." He took Ursula's hand and drew her forward.

"This lady is Mrs Ralph Paton. She was married to Captain Paton last March."

Ursula flushed and began to speak, but Flora forestalled her.

"What's the great idea?" he said, laughing. "Some scientific machine? Do we have bands round our wrists which register guilty heart-beats? There is such an invention isn't there?"

Poirot rapped gently on a table and cleared his throat significantly.

"You must not mind our being surprised," she said. "You see, we had no idea of such a thing. You and Ralph have kept your secret very well. I am -- very glad about it."

Going quickly to the other girl's side, she passed her hand through her arm.

"You are very kind. Miss Ackroyd," said Ursula in a low voice, "and you have every right to be exceedingly angry. Ralph behaved very badly -- especially to you."

"You needn't worry about that," said Flora, giving her arm a consoling little pat. "Ralph was in a corner and took the only way out. I should probably have done the same in his place. I do think he might have trusted me with the secret, though. I wouldn't have let him down."

"The board meeting's going to begin," said Flora. "M. Poirot hints that we mustn't talk. But just tell me one thing. Where is Ralph? You must know if anyone does."

"But I don't," cried Ursula, almost in a wail. "That's just it, I don't."

"Isn't he detained at Liverpool?" asked Raymond. "It said so in the paper."

"He is not at Liverpool," said Poirot shortly.

"Except Hercule Poirot, eh?" said Raymond.

Geoffrey Raymond lifted his eyebrows.

"Everything?" He whistled. "Whew! that's a tall order."

"You call it guessing. I call it knowing, my friend."

Poirot replied seriously to the other's banter. "Me, I know everything. Remember that."

"In fact," I remarked, "no one knows where he is."

"Do you mean to say you can really guess where Ralph Paton is hiding?" I asked incredulously.

"No," replied Poirot gravely, "not in Cranchester." He said no more, but at a gesture from him the assembled party took their seats. As they did so, the door opened once more and two other people came in and sat down near the door. They were Parker and the housekeeper.

"In Cranchester?" I hazarded.

There was a ring of satisfaction in his tone. And with the sound of it I saw a ripple of something like uneasiness pass over all those faces grouped at the other end of the room. There was a suggestion in all this as of a trap -- a trap that had closed.

"The number is complete," said Poirot. "Everyone is here."

With a cry Mrs Ackroyd sprang up, her throat working.

"What's the meaning of all this?" began Raymond.

Poirot read from a list in an important manner. "Mrs Ackroyd, Miss Flora Ackroyd, Major Blunt, Mr Geoffrey Raymond, Mrs Ralph Paton, John Parker, Elizabeth Russell." He laid the paper down on the table.

"You cannot go home, madame," said Poirot sternly, "until you have heard what I have to say." He paused a moment, then cleared his throat.

"I don't like it," she wailed. "I don't like it. I would much prefer to go home."

"The list I have just read," said Poirot, "is a list ofsupected persons. Every one of you present had the opportunity to kill Mr Ackroyd --"

"I will start at the beginning. When Miss Ackroyd asked me to investigate the case, I went up to Fernly Park with the good Doctor Sheppard. I walked with him along the terrace, where I was shown the footprints on the windowsill. From there Inspector Raglan took me along the path which leads to the drive. My eye was caught by a little |SS summer-house, and I searched it thoroughly. I found two things -- a scrap of starched cambric and an empty goose quill. The scrap of cambric immediately suggested to me a maid's apron. When Inspector Raglan showed me his list of the people in the house, I noticed at once that one of the maids -- Ursula Bourne, the parlourmaid -- had no real alibi."

"But I was held up by one point. The times did not fit. Ursula Bourne could certainly not have gone to the summer-house before nine-thirty, whereas the man must have got there by a few minutes past nine. I could, of course, assume that he waited there for half an hour. The only alternative supposition was that there had been two separate meetings in the summer-house that night. Eh bien, as soon as I went into that alternative I found several significant facts. I discovered that Miss Russell, the housekeeper, had visited Dr Sheppard that morning, and had displayed a good deal of interest in cures for victims of the drug habit. Taking that in conjunction with the goose quill, I assumed that the man in question came to Fernly to meet the housekeeper, and not Ursula Bourne. Who, then, did Ursula Bourne come to the rendezvous to meet? I was not long in doubt. First I found a ring -- a wedding ring -- with 'From R.' and a date inside it. Then I learnt that Ralph Paton had been seen coming up the path which led to the summer-house at twenty-five minutes past nine, and I also heard of a certain conversation which had taken place in the wood near the village that very afternoon -- a conversation between Ralph Paton and some unknown girl. So I had my facts succeeding each other in a neat and orderly manner. A secret marriage, an engagement announced on the day of the tragedy, the stormy interview in the wood, and the meeting arranged for the summer-house that night."

"According to her own story, she was in her bedroom from nine-thirty until ten. But supposing that instead she was in the summer-house? If so, she must have gone there to meet someone. Now we know from Dr Sheppard that someone from outside did come to the house that night -- the stranger whom he met just by the gate. At first glance it would seem that our problem was solved, and that the stranger went to the summer-house to meet Ursula Bourne. It was fairly certain that he did go to the summer-house because of the goose quill. That suggested at once to my mind a taker of drugs -- and one who had acquired the habit on the other side of the Atlantic where sniffing 'snow' is more common than in this country. The man whom Dr Sheppard met had an American accent, which fitted in with that supposition."

"Incidentally this proved to me one thing, that both Ralph Paton and Ursula Bourne (or Paton) had the strongest motives for wishing Mr Ackroyd out of the way. And it also made one other point unexpectedly clear. It could not have been Ralph Paton who was with Mr Ackroyd in the study at nine-thirty."

"So we come to another and most interesting aspect of the crime. Who was it in the room with Mr Ackroyd at nine-thirty? Not Ralph Paton, who was in the summer-house with his wife. Not Charles Kent, who had already left. Who, then? I posed my cleverest -- my most audacious question: Was anyone with him?"

Raymond, however, did not seem impressed, and lodged a mild protest.

Poirot leaned forward and shot the last words triumphantly at us, drawing back afterwards with the air of one who has made a decided hit.

"I don't know if you're trying to make me out a liar, M. Poirot, but the matter does not rest on my evidence alone except perhaps as to the exact words used. Remember, Major Blunt also heard Mr Ackroyd talking to someone. He was on the terrace outside, and couldn't catch the words clearly, but he distinctly heard the voices."

"I have not forgotten," he said quietly. "But Major Blunt was under the impression that it wasyou to whom Mr Ackroyd was speaking."

For a moment Raymond seemed taken aback. Then he recovered himself.

"Blunt knows now that he was mistaken," he said.

"Exactly," agreed the other man.

Poirot nodded.

"Yet there must have been some reason for his thinking so," mused Poirot. "Oh! no," he held up his hand in protest, "I know the reason you will give -- but it is not enough. We must seek elsewhere. I will put it this way. From the beginning of the case I have been struck by one thing -- the nature of those words which Mr Raymond overheard. It has been amazing to me that no one has commented on them has seen anything odd about them." He paused a minute, and then quoted softly: "… the calb on my purse have been so frequent of late that I fear it is impossible for me to accede to your request. Does nothing strike you as odd about that?"

"I don't think so," said Raymond. "He has frequently dictated letters to me, using almost exactly those same words."

"Exactly," cried Poirot. "That is what I seek to arrive at. Would any man use such a prase in talking to another? Impossible that that should be part of a real conversation. Now, if he had been dictating a letter --"

"But why? We have no evidence that there was anyone else in the room. No other voice but Mr Ackroyd's was heard, remember."

They all stared at him.

"Surely a man wouldn't read letters of that type aloud to himself- not unless he was -- well -- going balmy."

"You have all forgotten one thing," said Poirot softly: "the stranger who called at the house the preceding Wednesday."

"You mean he was reading a letter aloud," said Raymond slowly. "Even so, he must have been reading to someone."

"The Dictaphone Company," gasped Raymond. "I see it now. A dictaphone. That's what you think?"

Poirot nodded.

"Mr Ackroyd had promised to invest in a dictaphone, you remember. Me, I had the curiosity to inquire of the company in question. Their reply is that Mr Ackroyd did purchase a dictaphone from their representative. Why he concealed the matter from you, I do not know."

"But yes," said Poirot, nodding encouragingly, "on Wednesday. The young man was not of himself important. But the firm he represented interested me very much."

"He must have meant to surprise me with it," murmured Raymond. "He had quite a childish love of surprising people. Meant to keep it up his sleeve for a day or so. Probably was playing with it like a new toy. Yes, it fits in. You're quite right -- no one would use quite those words in casual conversation."

"It explains, too," said Poirot, "why Major Blunt thought it was you who were in the study. Such scraps as came to him were fragments of dictation, and so his subconscious mind deduced that you were with him. His conscious mind was occupied with something quite different -- the white figure he had caught a glimpse of. He fancied it was Miss Ackroyd. Really, of course, it was Ursula Bourne's white apron he saw as she was stealing down to the summerhouse."

"All the same," he remarked, "this discovery of yours, brilliant though it is (I'm quite sure I should never have thought of it), leaves the essential position unchanged. Mr Ackroyd was alive at nine-thirty, since he was speaking into the dictaphone. It seems clear that the man Charles Kent was really off the premises by then. As to Ralph Paton -?" He hesitated, glancing at Ursula.

Raymond had recovered from his first surprise.

"Is that your suggestion? Do you think he should come forward?"

Ralph Payton was standing at the door.

"It isn't that I doubt your story for a moment," explained Raymond. "I've always been quite sure Captain Paton was innocent. But one has to think of a court of law -- and the questions that would be asked. He is in a most unfortunate position, but if he were to come forward --"

Poirot interrupted him.

"It seems that you still don't trust my ability. As I said just now, I know everything: the truth of the phone call, the shoe print on the windowsill, Ralph Peyton's hiding place --"

He pointed with his forefinger in exaggeration, and everyone turned to look.

"Ralph and I parted just before a quarter to ten. He never went near the house, I am sure of that. He had no intention of doing so. The last thing on earth he wanted was to face his stepfather. He would have funked it badly."

Poirot turned and looked at me.

"You ask all the time, and you can't do without Cranchester. There he is, in fact."

"Where is he?" Major Brent snapped.

"Not very far." Bolo smiles.

"In Cranchester?" I asked.

Her colour flared up, but she answered steadily enough.

"Of course. If you know where he is --"
