Arthur Conan Doyle - Arthur Conan Doyle - The Complete Sherlock Holmes

I looked out of the open window. The moon still shone brightiy on that angle of the house. We were a good sixty feet from the ground, and, look where I would, I could see no foothold, nor as much as a crevice in the brickwork.

"It is absolutely impossible," I answered.

"Without aid it is so. But suppose you had a friend up here who lowered you this good stout rope which I see in the corner, securing one end of it to this great hook in the wall. Then, I think, if you were an active man, you might swarm up, wooden leg and all. You would depart, of course, in the same fashion, and your ally would draw up the rope, untie it from the hook, shut the window, snib it on the inside, and get away in the way that he originally came. As a minor point, it may be noted," he continued, fingering the rope, "that our wooden-legged friend, though a fair climber, was not a professional sailor. His hands were far from horny. My lens discloses more than one blood-mark, especially towards the end of the rope, from which I gather that he slipped down with such velocity that he took the skin off his hands."

"This is all very well," said I; "but the thing becomes more unintelligible than ever. How about this mysterious ally? How came he into the room?"

"Yes, the ally!" repeated Holmes pensively. "There are features of interest about this ally. He lifts the case from the regions of the commonplace. I fancy that this ally breaks fresh ground in the annals of crime in this country — though parallel cases suggest themselves from India and, if my memory serves me, from Senegambia."

"How came he, then?" I reiterated. "The door is locked; the window is inaccessible. Was it through the chimney?"

"The grate is much too small," he answered. "I had already considered that possibility."

"How, then?" I persisted.

"You will not apply my precept," he said, shaking his head. "How often have I said to you that when you have eliminated the impossible, whatever remains, however improbable, must be the truth? We know that he did not come through the door, the window, or the chimney. We also know that he could not have been concealed in the room, as there is no concealment possible. When, then, did he come?"

"He came through the hole in the roof!" I cried.

"Of course he did. He must have done so. If you will have the kindness to hold the lamp for me, we shall now extend our researches to the room above — the secret room in which the treasure was found."

He mounted the steps, and, seizing a rafter with either hand, he swung himself up into the garret. Then, lying on his face, he reached down for the lamp and held it while I followed him.

The chamber in which we found ourselves was about ten feet one way and six the other. The floor was formed by the rafters, with thin lath and plaster between, so that in walking one had to step from beam to beam. The roof ran up to an apex and was evidently the inner shell of the true roof of the house. There was no furniture of any sort, and the accumulated dust of years lay thick upon the floor.

"Here you are, you see," said Sherlock Holmes, putting his hand against the sloping wall. "This is a trapdoor which leads out on to the roof. I can press it back, and here is the roof itself, sloping at a gentle angle. This, then, is the way by which Number One entered. Let us see if we can find some other traces of his individuality?"

He held down the lamp to the floor, and as he did so I saw for the second time that night a startled, surprised look come over his face. For myself, as I followed his gaze, my skin was cold under my clothes. The floor was covered thickly with the prints of a naked foot — clear, well-defined, perfectly formed, but scarce half the size of those of an ordinary man.

"Holmes," I said in a whisper, "a child has done this horrid thing."

He had recovered his self-possession in an instant.

"I was staggered for the moment," he said, "but the thing is quite natural. My memory failed me, or I should have been able to foretell it. There is nothing more to be learned here. Let us go down."

"What is your theory, then, as to those footmarks?" I asked eagerly when we had regained the lower room once more.

"My dear Watson, try a little analysis yourself," said he with a touch of impatience. "You know my methods. Apply them, and it will be instructive to compare results."

"I cannot conceive anything which will cover the facts," I answered.

"It will be clear enough to you soon," he said, in an offhand way. "I think that there is nothing else of importance here, but I will look."

He whipped out his lens and a tape measure and hurried about the room on his knees, measuring, comparing, examining, with his long thin nose only a few inches from the planks and his beady eyes gleaming and deep-set like those of a bird. So swift, silent, and furtive were his movements, like those of a trained bloodhound picking out a scent, that I could not but think what a terrible criminal he would have made had he turned his energy and sagacity against the law instead of exerting them in its defence. As he hunted about, he kept muttering to himself, and finally he broke out into a loud crow of delight.

"We are certainly in luck," said he. "We ought to have very little trouble now. Number One has had the misfortune to tread in the creosote. You can see the outline of the edge of his small foot here at the side of this evil-smelling mess. The carboy has been cracked, you see, and the stuff has leaked out."

"What then?" I asked.

"Why, we have got him, that's all," said he.

"I know a dog that would follow that scent to the world's end. If a pack can track a trailed herring across a shire, how far can a specially trained hound follow so pungent a smell as this? It sounds like a sum in the rule of three. The answer should give us the — But hallo! here are the accredited representatives of the law."

Heavy steps and the clamour of loud voices were audible from below, and the hall door shut with a loud crash.

"Before they come," said Holmes, "just put your hand here on this poor fellow's arm, and here on his leg. What do you feel?"

The muscles are as hard as a board," I answered.

"Quite so. They are in a state of extreme contraction, far exceeding the usual rigor mortis. Coupled with this distortion of the face, this Hippocratic smile, or 'risus sardonicus,' as the old writers called it, what conclusion would it suggest to your mind?"

"Death from some powerful vegetable alkaloid," I answered, "some strychnine-like substance which would produce tetanus."

"That was the idea which occurred to me the instant I saw the drawn muscles of the face. On getting into the room I at once looked for the means by which the poison had entered the system. As you saw, I discovered a thorn which had been driven or shot with no great force into the scalp. You observe that the part struck was that which would be turned towards the hole in the ceiling if the man were erect in his chair. Now examine this thorn."

I took it up gingerly and held it in the light of the lantern. It was long, sharp, and black, with a glazed look near the point as though some gummy substance had dried upon it. The blunt end had been trimmed and rounded off with a knife.

"Is that an English thorn?" he asked.

"No, it certainly is not."

"With all these data you should be able to draw some just inference. But here are the regulars, so the auxiliary forces may beat a retreat."

As he spoke, the steps which had been coming nearer sounded loudly on the passage, and a very stout, portly man in a gray suit strode heavily into the room. He was red-faced, burly, and plethoric, with a pair of very small twinkling eyes which looked keenly out from between swollen and puffy pouches. He was closely followed by an inspector in uniform and by the still palpitating Thaddeus Sholto.
