“No.”

“What do you mean, then?”

“Oh, you know the stories that the peasants tell about a phantom hound, and so on. It is said to be heard at night upon the moor. I was wondering if there were any evidence of such a sound tonight.”

“We heard nothing of the kind,” said I.

“And what is your theory of this poor fellow’s death?”

“I have no doubt that anxiety and exposure have driven him off his head. He has rushed about the moor in a crazy state and eventually fallen over here and broken his neck.”

“That seems the most reasonable theory,” said Stapleton, and he gave a sigh which I took to indicate his relief. “What do you think about it, Mr. Sherlock Holmes?”

My friend bowed his compliments. “You are quick at identification,” said he.

“We have been expecting you in these parts since Dr. Watson came down. You are in time to see a tragedy.”

“Yes, indeed. I have no doubt that my friend’s explanation will cover the facts. I will take an unpleasant remembrance back to London with me tomorrow.”

“Oh, you return tomorrow?”

“That is my intention.”

“I hope your visit has cast some light upon those occurrences which have puzzled us?”

Holmes shrugged his shoulders.

“One cannot always have the success for which one hopes. An investigator needs facts and not legends or rumours. It has not been a satisfactory case.”

My friend spoke in his frankest and most unconcerned manner. Stapleton still looked hard at him. Then he turned to me.

“I would suggest carrying this poor fellow to my house, but it would give my sister such a fright that I do not feel justified in doing it. I think that if we put something over his face he will be safe until morning.”

And so it was arranged. Resisting Stapleton’s offer of hospitality, Holmes and I set off to Baskerville Hall, leaving the naturalist to return alone. Looking back we saw the figure moving slowly away over the broad moor, and behind him that one black smudge on the silvered slope which showed where the man was lying who had come so horribly to his end.

“We’re at close grips at last,” said Holmes as we walked together across the moor. “What a nerve the fellow has! How he pulled himself together in the face of what must have been a paralyzing shock when he found that the wrong man had fallen a victim to his plot. I told you in London, Watson, and I tell you now again, that we have never had a foeman more worthy of our steel.”

“I am sorry that he has seen you.”

“And so was I at first. But there was no getting out of it.”
