"No, but you evidently think it."
"Since the tragedy, Mr. Holmes, there have come to my ears several incidents which are hard to reconcile with the settled order of Nature."
"For example?"
"I find that before the terrible event occurred several people had seen a creature upon the moor which corresponds with this Baskerville demon, and which could not possibly be any animal known to science.
They all agreed that it was a huge creature, luminous, ghastly, and spectral.
I have cross-examined these men, one of them a hard-headed countryman, one a farrier, and one a moorland farmer, who all tell the same story of this dreadful apparition, exactly corresponding to the hell-hound of the legend.
I assure you that there is a reign of terror in the district, and that it is a hardy man who will cross the moor at night."
"And you, a trained man of science, believe it to be supernatural?"
"I do not know what to believe."
Holmes shrugged his shoulders. "I have hitherto confined my investigations to this world," said he. "In a modest way I have combated evil, but to take on the Father of Evil himself would, perhaps, be too ambitious a task. Yet you must admit that the footmark is material."
