A slight gesture from Poirot enjoined1 me to stay behind the rest. I obeyed, going over to the fire and thoughtfully stirring the big logs on it with the toe of my boot.
I was puzzled. For the first time I was absolutely at sea as to Poirot’s meaning. For a moment I was inclined to think that the scene I had just witnessed was a gigantic piece of bombast—that he had been what he called “playing the comedy” with a view to making himself interesting and important. But, in spite of myself, I was forced to believe in an underlying2 reality. There had been real menace in his words—a certain indisputable sincerity3. But I still believed him to be on entirely4 the wrong tack5.
When the door shut behind the last of the party he came over to the fire.
“Well, my friend,” he said quietly, “and what do you think of it all?”
“I don’t know what to think,” I said frankly6. “What was the point? Why not go straight to Inspector7 Raglan with the truth instead of giving the guilty person this elaborate warning?”
Poirot sat down and drew out his case of tiny Russian290 cigarettes. He smoked for a minute or two in silence. Then:—
“Use your little gray cells,” he said. “There is always a reason behind my actions.”
I hesitated for a moment, and then I said slowly:
“The first one that occurs to me is that you yourself do not know who the guilty person is, but that you are sure that he is to be found amongst the people here to-night. Therefore your words were intended to force a confession8 from the unknown murderer?”
Poirot nodded approvingly.
“A clever idea, but not the truth.”
“I thought, perhaps, that by making him believe you knew, you might force him out into the open—not necessarily by confession. He might try to silence you as he formerly9 silenced Mr. Ackroyd—before you could act to-morrow morning.”
“A trap with myself as the bait! Merci, mon ami, but I am not sufficiently10 heroic for that.”
“Then I fail to understand you. Surely you are running the risk of letting the murderer escape by thus putting him on his guard?”
Poirot shook his head.
“He cannot escape,” he said gravely. “There is only one way out—and that way does not lead to freedom.”
“You really believe that one of those people here to-night committed the murder?” I asked incredulously.
“Yes, my friend.”
“Which one?”
There was a silence for some minutes. Then Poirot291 tossed the stump11 of his cigarette into the grate and began to speak in a quiet, reflective tone.
“I will take you the way that I have traveled myself. Step by step you shall accompany me, and see for yourself that all the facts point indisputably to one person. Now, to begin with, there were two facts and one little discrepancy12 in time which especially attracted my attention. The first fact was the telephone call. If Ralph Paton were indeed the murderer, the telephone call became meaningless and absurd. Therefore, I said to myself, Ralph Paton is not the murderer.
“I satisfied myself that the call could not have been sent by any one in the house, yet I was convinced that it was amongst those present on the fatal evening that I had to look for my criminal. Therefore I concluded that the telephone call must have been sent by an accomplice13. I was not quite pleased with that deduction14, but I let it stand for the minute.
“I next examined the motive15 for the call. That was difficult. I could only get at it by judging its result. Which was—that the murder was discovered that night instead of—in all probability—the following morning. You agree with that?”
“Ye-es,” I admitted. “Yes. As you say, Mr. Ackroyd, having given orders that he was not to be disturbed, nobody would have been likely to go to the study that night.”
“Très bien. The affair marches, does it not? But matters were still obscure. What was the advantage of having the crime discovered that night in preference to292 the following morning? The only idea I could get hold of was that the murderer, knowing the crime was to be discovered at a certain time, could make sure of being present when the door was broken in—or at any rate immediately afterwards. And now we come to the second fact—the chair pulled out from the wall. Inspector Raglan dismissed that as of no importance. I, on the contrary, have always regarded it as of supreme16 importance.
“In your manuscript you have drawn17 a neat little plan of the study. If you had it with you this minute you would see that—the chair being drawn out in the position indicated by Parker—it would stand in a direct line between the door and the window.”
“The window!” I said quickly.
“You, too, have my first idea. I imagined that the chair was drawn out so that something connected with the window should not be seen by any one entering through the door. But I soon abandoned that supposition, for though the chair was a grandfather with a high back, it obscured very little of the window—only the part between the sash and the ground. No, mon ami—but remember that just in front of the window there stood a table with books and magazines upon it. Now that table was completely hidden by the drawn-out chair—and immediately I had my first shadowy suspicion of the truth.
“Supposing that there had been something on that table not intended to be seen? Something placed there by the murderer? As yet I had no inkling of what that something might be. But I knew certain very interesting293 facts about it. For instance, it was something that the murderer had not been able to take away with him at the time that he committed the crime. At the same time it was vital that it should be removed as soon as possible after the crime had been discovered. And so—the telephone message, and the opportunity for the murderer to be on the spot when the body was discovered.
“Now four people were on the scene before the police arrived. Yourself, Parker, Major Blunt, and Mr. Raymond. Parker I eliminated at once, since at whatever time the crime was discovered, he was the one person certain to be on the spot. Also it was he who told me of the pulled-out chair. Parker, then, was cleared (of the murder, that is. I still thought it possible that he had been blackmailing18 Mrs. Ferrars). Raymond and Blunt, however, remained under suspicion since, if the crime had been discovered in the early hours of the morning, it was quite possible that they might have arrived on the scene too late to prevent the object on the round table being discovered.
“Now what was that object? You heard my arguments to-night in reference to the scrap19 of conversation overheard? As soon as I learned that a representative of a dictaphone company had called, the idea of a dictaphone took root in my mind. You heard what I said in this room not half an hour ago? They all agreed with my theory—but one vital fact seems to have escaped them. Granted that a dictaphone was being used by Mr. Ackroyd that night—why was no dictaphone found?”
“I never thought of that,” I said.
294
“We know that a dictaphone was supplied to Mr. Ackroyd. But no dictaphone has been found amongst his effects. So, if something was taken from that table—why should not that something be the dictaphone? But there were certain difficulties in the way. The attention of every one was, of course, focused on the murdered man. I think any one could have gone to the table unnoticed by the other people in the room. But a dictaphone has a certain bulk—it cannot be slipped casually20 into a pocket. There must have been a receptacle of some kind capable of holding it.
“You see where I am arriving? The figure of the murderer is taking shape. A person who was on the scene straightway, but who might not have been if the crime had been discovered the following morning. A person carrying a receptacle into which the dictaphone might be fitted——”
I interrupted.
“But why remove the dictaphone? What was the point?”
“You are like Mr. Raymond. You take it for granted that what was heard at nine-thirty was Mr. Ackroyd’s voice speaking into a dictaphone. But consider this useful invention for a little minute. You dictate21 into it, do you not? And at some later time a secretary or a typist turns it on, and the voice speaks again.”
Poirot nodded.
“Yes, I mean that. At nine-thirty Mr. Ackroyd was295 already dead. It was the dictaphone speaking—not the man.”
“And the murderer switched it on. Then he must have been in the room at that minute?”
“Possibly. But we must not exclude the likelihood of some mechanical device having been applied—something after the nature of a time lock, or even of a simple alarm clock. But in that case we must add two qualifications to our imaginary portrait of the murderer. It must be some one who knew of Mr. Ackroyd’s purchase of the dictaphone and also some one with the necessary mechanical knowledge.
“I had got thus far in my own mind when we came to the footprints on the window ledge23. Here there were three conclusions open to me. (1) They might really have been made by Ralph Paton. He had been at Fernly that night, and might have climbed into the study and found his uncle dead there. That was one hypothesis. (2) There was the possibility that the footmarks might have been made by somebody else who happened to have the same kind of studs in his shoes. But the inmates24 of the house had shoes soled with crepe rubber, and I declined to believe in the coincidence of some one from outside having the same kind of shoes as Ralph Paton wore. Charles Kent, as we know from the barmaid of the Dog and Whistle, had on a pair of boots ‘clean dropping off him.’ (3) Those prints were made by some one deliberately25 trying to throw suspicion on Ralph Paton. To test this last conclusion, it was necessary to ascertain26 certain facts. One pair of Ralph’s shoes had been296 obtained from the Three Boars by the police. Neither Ralph nor any one else could have worn them that evening, since they were downstairs being cleaned. According to the police theory, Ralph was wearing another pair of the same kind, and I found out that it was true that he had two pairs. Now for my theory to be proved correct it was necessary for the murderer to have worn Ralph’s shoes that evening—in which case Ralph must have been wearing yet a third pair of footwear of some kind. I could hardly suppose that he would bring three pairs of shoes all alike—the third pair of footwear were more likely to be boots. I got your sister to make inquiries27 on this point—laying some stress on the color, in order—I admit it frankly—to obscure the real reason for my asking.
“You know the result of her investigations28. Ralph Paton had had a pair of boots with him. The first question I asked him when he came to my house yesterday morning was what he was wearing on his feet on the fatal night. He replied at once that he had worn boots—he was still wearing them, in fact—having nothing else to put on.
“So we get a step further in our description of the murderer—a person who had the opportunity to take these shoes of Ralph Paton’s from the Three Boars that day.”
He paused, and then said, with a slightly raised voice:—
“There is one further point. The murderer must have been a person who had the opportunity to purloin29 that297 dagger30 from the silver table. You might argue that any one in the house might have done so, but I will recall to you that Miss Ackroyd was very positive that the dagger was not there when she examined the silver table.”
He paused again.
“Let us recapitulate—now that all is clear. A person who was at the Three Boars earlier that day, a person who knew Ackroyd well enough to know that he had purchased a dictaphone, a person who was of a mechanical turn of mind, who had the opportunity to take the dagger from the silver table before Miss Flora31 arrived, who had with him a receptacle suitable for hiding the dictaphone—such as a black bag, and who had the study to himself for a few minutes after the crime was discovered while Parker was telephoning for the police. In fact—Dr. Sheppard!”
