cried. "It is evidently a case of
extraordinary interest, and one which presented immense opportunities to
the scientific expert. That gravel page upon which I might have read so
much has been long ere this smudged by the rain and defaced by the clogs
of curious peasants. Oh, Dr. Mortimer, Dr. Mortimer, to think that you
should not have called me in! You have indeed much to answer for."

"I could not call you in, Mr. Holmes, without disclosing these facts to
the world, and I have already given my reasons for not wishing to do so.
Besides, besides--"

"Why do you hesitate?"

"There is a realm in which the most acute and most experienced of
detectives is helpless."

"You mean that the thing is supernatural?"

"I did not positively say so."

"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."

"The original hound was material enough to tug a man's throat out, and
yet he was diabolical as well."

"I see that you have quite gone over to the supernaturalists. But now,
Dr. Mortimer, tell me this. If you hold these views, why have you come
to consult me at all? You tell me in the same breath that it is useless
to investigate Sir Charles's death, and that you desire me to do it."

"I did not say that I desired you to do it."

"Then, how can I assist you?"

"By advising me as to wh
