"This is all an insoluble mystery to me," said I. "It grows darker instead of clearer."
"On the contrary," he answered, "it clears every instant. I only require a few missing links to have an entirely connected case."
We had almost forgotten our companion's presence since we entered the chamber. He was still standing in the doorway, the very picture of terror, wringing his hands and moaning to him– self. Suddenly, however, he broke out into a sharp, querulous cry.
"The treasure is gone!" he said. "They have robbed him of the treasure! There is the hole through which we lowered it. I helped him to do it! I was the last person who saw him! I left him here last night, and I heard him lock the door as I came downstairs."
"What time was that?"
"It was ten o'clock. And now he is dead, and the police will be called in, and I shall be suspected of having had a hand in it. Oh, yes, I am sure I shall. But you don't think so, gentlemen? Surely you don't think that it was l? Is it likely that I would have brought you here if it were l? Oh, dear! oh, dear! I know that I shall go mad!"
He jerked his arms and stamped his feet in a kind of convul– sive frenzy.
"You have no reason for fear, Mr. Sholto," said Holmes kindly, putting his hand upon his shoulder; "take my advice and drive down to the station to report the matter to the police. Offer to assist them in every way. We shall wait here until your return."
The little man obeyed in a half-stupefied fashion, and we heard him stumbling down the stairs in the dark.
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.
