you stand in front of the clock, Jervis," he said, "and raise your hand as if winding it? Thanks; keep like that while I expose a plate."
I remained thus, in the position that the dead man was assumed to have occupied at the moment of the murder, while the plate was exposed, and then, before I moved, Thorndyke marked the position of my feet with a blackboard chalk. He next set up the tripod over the chalk marks, and took two photographs from that position, and finally photographed the body itself.
The photographic operations being concluded, he next proceeded, with remarkable skill and rapidity, to lay out on the sketch-block a ground-plan of the room, showing the exact position of the various objects, on a scale of a quarter of an inch to the foot—a process that the inspector was inclined to view with some impatience.
"You don't spare trouble, Doctor," he remarked; "nor time either," he added, with a significant glance at his watch.
"No," answered Thorndyke, as he detached the finished sketch from the block; "I try to collect all the facts that may bear on a case. They may prove worthless, or they may turn out of vital importance; one never knows beforehand, so I collect them all. But here, I think, is Dr. Egerton."
The police-surgeon greeted Thorndyke with respectful cordiality, and we proceeded at once to the examination of the body. Drawing out the thermometer, my colleague noted the reading, and passed the instrument to Dr. Egerton.
"Dead about ten hours," remarked the latter, after a glance at it. "This was a very determined and mysterious murder."
"Very," said Thorndyke. "Feel that dagger, Jervis."
I touched the hilt, and felt the characteristic grating of bone.
"It is through the edge of a rib!" I exclaimed.
"Yes; it must have been used with extraordinary force. And you notice that the clothing is screwed up slightly, as if the blade had been rotated as it was driven in. That is a very peculiar feature, especially when taken together with the violence of the blow."
"It is singular, certainly," said Dr. Egerton, "though I don't know that it helps us much. Shall we withdraw the dagger before moving the body?"
"Certainly," replied Thorndyke, "or the movement may produce fresh injuries. But wait." He took a piece of string from his pocket, and, having drawn the dagger out a couple of inches, stretched the string in a line parallel to the flat of the blade. Then, giving me the ends to hold, he drew the weapon out completely. As the blade emerged, the twist in the clothing disappeared. "Observe," said he, "that the string gives the direction of the wound, and that the cut in the clothing no longer coincides with it. There is quite a considerable angle, which is the measure of the rotation of the blade."
"Yes, it is odd," said Dr. Egerton, "though, as I said, I doubt that it helps us."
"At present," Thorndyke rejoined dryly, "we are noting the facts."
"Quite so," agreed the other, reddening slightly; "and perhaps we had better move the body to the bedroom, and make a preliminary inspection of the wound."
We carried the corpse into the bedroom, and, having examined the wound without eliciting anything new, covered the remains with a sheet, and returned to the sitting-room.
"Well, gentlemen," said the inspector, "you have examined the body and the wound, and you have measured the floor and the furniture, and taken photographs, and made a plan, but we don't seem much more forward. Here's a man murdered in his rooms. There is only one entrance to the flat, and that was bolted on the inside at the time of the murder. The windows are some forty feet from the ground; there is no rain-pipe near any of them; they are set flush in the wall, and there isn't a foothold for a fly on any part of that wall. The grates are modern, and there isn't room for a good-sized cat to crawl up any of the chimneys. Now, the question is, How did the murderer get in, and how did he get out again?"
"Still," said Mr. Marchmont, "the fact is that he did get in, and that he is not here now; and therefore he must have got out; and therefore it must have been possible for him to get out. And, further, it must be possible to discover how he got out."
The inspector smiled sourly, but made no reply.
"The circumstances," said Thorndyke, "appear to have been these: The deceased seems to have been alone; there is no trace of a second occupant of the room, and only one half-emptied tumbler on the table. He was sitting reading when apparently he noticed that the clock had stopped—at ten minutes to twelve; he laid his book, face downwards, on the table, and rose to wind the clock, and as he was winding it he met his death."
"By a stab dealt by a left-handed man, who crept up behind him on tiptoe," added the inspector.
Thorndyke nodded. "That would seem to be so," he said. "But now let us call in the porter, and hear what he has to tell us."
The custodian was not difficult to find, being, in fact, engaged at that moment in a survey of the premises through the slit of the letter-box.
"Do you know what persons visited these rooms last night?" Thorndyke asked him, when he entered looking somewhat sheepish.
"A good many were in and out of the building," was the answer, "but I can't say if any of them came to this flat. I saw Miss Curtis pass in about nine."
"My daughter!" exclaimed Mr. Curtis, with a start. "I didn't know that."
"She left about nine-thirty," the porter added.
"Do you know what she came about?" asked the inspector.
"I can guess," replied Mr. Curtis.
"Then don't say," interrupted Mr. Marchmont. "Answer no questions."
"You're very close, Mr. Marchmont," said the inspector; "we are not suspecting the young lady. We don't ask, for instance, if she is left-handed."
He glanced craftily at Mr. Curtis as he made this remark, and I noticed that our client suddenly turned deathly pale, whereupon the inspector looked away again quickly, as though he had not observed the change.
"Tell us about those Italians again," he said, addressing the porter. "When did the first of them come here?"
"About a week ago," was the reply. "He was a common-looking man—looked like an organ-grinder—and he brought a note to my lodge. It was in a dirty envelope, and was addressed 'Mr. Hartridge, Esq., Brackenhurst Mansions,' in a very bad handwriting. The man gave me the note and asked me to give it to Mr. Hartridge; then he went away, and I took the note up and dropped it into the letter-box."
"What happened next?"
"Why, the very next day an old hag of an Italian woman—one of them fortune-telling swines with a cage of birds on a stand—came and set up just by the main doorway. I soon sent her packing, but, bless you! she was back again in ten minutes, birds and all. I sent her off again—I kept on sending her off, and she kept on coming back, until I was reg'lar wore to a thread."
"You seem to have picked up a bit since then," remarked the inspector with a grin and a glance at the sufferer's very pronounced bow-window.
"Perhaps I have," the custodian replied haughtily. "Well, the next day there was a ice-cream man—a reg'lar waster, he was. Stuck outside as if he was froze to the pavement. Kept giving the errand-boys tasters, and when I tried to move him on, he told me not to obstruct his business. Business, indeed! Well, there them boys stuck, one after the other, wiping their tongues round the bottoms of them glasses, until I was fit to bust with aggravation. And he kept me going all day.
"Then, the day after that there was a barrel-organ, with a mangy-looking monkey on it. He was the worst of all. Profane, too, he was. Kept mixing up sacred tunes and comic songs: 'Rock of Ages,' 'Bill Bailey,' 'Cujus Animal,' and 'Over the Garden Wall.' And when I tried to move him on, that little blighter of a monkey made a run at my leg; and then the man grinned and started playing, 'Wait till the Clouds roll by.' I tell you, it was fair sickening."
He wiped his brow at the recollection, and the inspector smiled appreciatively.
"And
