“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 what I should do with Sir Henry Baskerville, who arrives at Waterloo Station”—Dr. Mortimer looked at his watch—“in exactly one hour and a quarter.”

“He being the heir?”

“Yes. On the death of Sir Charles we inquired for this young gentleman and found that he had been farming in Canada. From the accounts which have reached us he is an excellent fellow in every way. I speak now not as a medical man but as a trustee and executor of Sir Charles’s will.”

“There is no other claimant, I presume?”

“None. The only other kinsman whom we have been able to trace was Rodger Baskerville, the youngest of three brothers of whom poor Sir Charles was the elder. The second brother, who died young, is the father of this lad Henry. The third, Rodger, was the black sheep of the family. He came of the old masterful Baskerville strain and was the very image, they tell me, of the family picture of old Hugo. He made England too hot to hold him, fled to Central America, and died there in 1876 of yellow fever. Henry is the last of the Baskervilles. In one hour and five minutes I meet him at Waterloo Station. I have had a wire that he arrived at Southampton this morning. Now, Mr. Holmes, what would you advise me to do with him?”

“Why should he not go to the home of his fathers?”

“It seems natural, does it not? And yet, consider that every Baskerville who goes there meets with an evil fate. I feel sure that if Sir Charles could have spoken with me before his death he would have warned me against bringing this, the last of the old race, and the heir to great wealth, to that deadly place. And yet it cannot be denied that the prosperity of the whole poor, bleak countryside depends upon his presence. All the good work which has been done by Sir Charles will crash to the ground if there is no tenant of the Hall. I fear lest I should be swayed too much by my own obvious interest in the matter, and that is why I bring the case before you and ask for your advice.”

Holmes considered for a little time.

“Put into plain words, the matter is this,” said he. “In your opinion there is a diabolical agency which makes Dartmoor an unsafe abode for a Baskerville—that is your opinion?”

“At least I might go the length of saying that there is some evidence that this may be so.”
