“Not at all. The bottle was full of it, and it is inconceivable that the first two glasses were clear and the third heavily charged with it. There are two possible explanations, and only two. One is that after the second glass was filled the bottle was violently agitated, and so the third glass received the beeswing. That does not appear probable. No, no, I am sure that I am right.”
“What, then, do you suppose?”
That only two glasses were used, and that the dregs of both were poured into a third glass, so as to give the false impression that three people had been here. In that way all the beeswing would be in the last glass, would it not? Yes, I am convinced that this is so. But if I have hit upon the true explanation of this one small phenomenon, then in an instant the case rises from the commonplace to the exceedingly remarkable, for it can only mean that Lady Brackenstall and her maid have deliberately lied to us, that not one word of their story is to be believed, that they have some very strong reason for covering the real criminal, and that we must construct our case for ourselves without any help from them. That is the mission which now lies before us, and here, Watson, is the Sydenham train.”
The household at the Abbey Grange were much surprised at our return, but Sherlock Holmes, finding that Stanley Hopkins had gone off to report to headquarters, took possession of the dining-room, locked the door upon the inside, and devoted himself for two hours to one of those minute and laborious investigations which form the solid basis on which his brilliant edifices of deduction were reared. Seated in a corner like an interested student who observes the demonstration of his professor, I followed every step of that remarkable research. The window, the curtains, the carpet, the chair, the rope –mdash; each in turn was minutely examined and duly pondered. The body of the unfortunate baronet had been removed, and all else remained as we had seen it in the morning. Finally, to my astonishment, Holmes climbed up on to the massive mantelpiece. Far above his head hung the few inches of red cord which were still attached to the wire. For a long time he gazed upward at it, and then in an attempt to get nearer to it he rested his knee upon a wooden bracket on the wall. This brought his hand within a few inches of the broken end of the rope, but it was not this so much as the bracket itself which seemed to engage his attention. Finally, he sprang down with an ejaculation of satisfaction.
“It’s all right, Watson,” said he. We have got our case –mdash; one of the most remarkable in our collection. But, dear me, how slow-witted I have been, and how nearly I have committed the blunder of my lifetime! Now, I think that, with a few missing links, my chain is almost complete.”
“You have got your men?”
Man, Watson, man. Only one, but a very formidable person. Strong as a lion –mdash; witness the blow that bent that poker! Six foot three in height, active as a squirrel, dexterous with his fingers, finally, remarkably quick-witted, for this whole ingenious story is of his concoction. Yes, Watson, we have come upon the handiwork of a very remarkable individual. And yet, in that bell-rope, he has given us a clue which should not have left us a doubt.”
“Where was the clue?”
Well, if you were to pull down a bell-rope, Watson, where would you expect it to break? Surely at the spot where it is attached to the wire. Why should it break three inches from the top, as this one has done?”
“Because it is frayed there?”
“Exactly. This end, which we can examine, is frayed. He was cunning enough to do that with his knife. But the other end is not frayed. You could not observe that from here, but if you were on the mantelpiece you would see that it is cut clean off without any mark of fraying whatever. You can reconstruct what occurred. The man needed the rope. He would not tear it down for fear of giving the alarm by ringing the bell. What did he do? He sprang up on the mantelpiece, could not quite reach it, put his knee on the bracket –mdash; you will see the impression in the dust –mdash; and so got his knife to bear upon the cord. I could not reach the place by at least three inches –mdash; from which I infer that he is at least three inches a bigger man than I. Look at that mark upon the seat of the oaken chair! What is it?”
