A low moan had fallen upon our ears. There it was again upon our left! On that side a ridge of rocks ended in a sheer cliff which overlooked a stone-strewn slope. On its jagged face was spread-eagled some dark, irregular object. As we ran towards it the vague outline hardened into a definite shape. It was a prostrate man face downward upon the ground, the head doubled under him at a horrible angle, the shoulders rounded and the body hunched together as if in the act of throwing a somersault. So grotesque was the attitude that I could not for the instant realise that that moan had been the passing of his soul. Not a whisper, not a rustle, rose now from the dark figure over which we stooped. Holmes laid his hand upon him and held it up again with an exclamation of horror. The gleam of the match which he struck shone upon his clotted fingers and upon the ghastly pool which widened slowly from the crushed skull of the victim. And it shone upon something else which turned our hearts sick and faint within us—the body of Sir Henry Baskerville!

There was no chance of either of us forgetting that peculiar ruddy tweed suit—the very one which he had worn on the first morning that we had seen him in Baker Street. We caught the one clear glimpse of it, and then the match flickered and went out, even as the hope had gone out of our souls. Holmes groaned, and his face glimmered white through the darkness.

“The brute! The brute!” I cried with clenched hands. “Oh Holmes, I shall never forgive myself for having left him to his fate.”

“I am more to blame than you, Watson. In order to have my case well rounded and complete, I have thrown away the life of my client. It is the greatest blow which has befallen me in my career. But how could I know—how could I know—that he would risk his life alone upon the moor in the face of all my warnings?”

“That we should have heard his screams—my God, those screams!—and yet have been unable to save him! Where is this brute of a hound which drove him to his death? It may be lurking among these rocks at this instant. And Stapleton, where is he? He shall answer for this deed.”

“He shall. I will see to that. Uncle and nephew have been murdered—the one frightened to death by the very sight of a beast which he thought to be supernatural, the other driven to his end in his wild flight to escape from it. But now we have to prove the connection between the man and the beast. Save from what we heard, we cannot even swear to the existence of the latter, since Sir Henry has evidently died from the fall. But, by heavens, cunning as he is, the fellow shall be in my power before another day is past!”
