“I must take the view, your Grace, that when a man embarks upon a crime, he is morally guilty of any other crime which may spring from it.”

“Morally, Mr. Holmes.  No doubt you are right.  But surely not in the eyes of the law.  A man cannot be condemned for a murder at which he was not present, and which he loathes and abhors as much as you do.  The instant that he heard of it he made a complete confession to me, so filled was he with horror and remorse.  He lost not an hour in breaking entirely with the murderer.  Oh, Mr. Holmes, you must save him—­you must save him!  I tell you that you must save him!” The Duke had dropped the last attempt at self-command, and was pacing the room with a convulsed face and with his clenched hands raving in the air.  At last he mastered himself and sat down once more at his desk.  “I appreciate your conduct in coming here before you spoke to anyone else,” said he.  “At least, we may take counsel how far we can minimize this hideous scandal.”

“Exactly,” said Holmes.  “I think, your Grace, that this can only be done by absolute frankness between us.  I am disposed to help your Grace to the best of my ability, but, in order to do so, I must understand to the last detail how the matter stands.  I realize that your words applied to Mr. James Wilder, and that he is not the murderer.”

Sherlock Holmes smiled demurely.

“Your Grace can hardly have heard of any small reputation which I possess, or you would not imagine that it is so easy to escape me.  Mr. Reuben Hayes was arrested at Chesterfield, on my information, at eleven o’clock last night.  I had a telegram from the head of the local police before I left the school this morning.”

The Duke leaned back in his chair and stared with amazement at my friend.

“You seem to have powers that are hardly human,” said he.  “So Reuben Hayes is taken?  I am right glad to hear it, if it will not react upon the fate of James.”

“Your secretary?”

“No, sir, my son.”

It was Holmes’s turn to look astonished.

“I confess that this is entirely new to me, your Grace.  I must beg you to be more explicit.”

“I will conceal nothing from you.  I agree with you that complete frankness, however painful it may be to me, is the best policy in this desperate situation to which James’s folly and jealousy have reduced us.  When I was a very young man, Mr. Holmes, I loved with such a love as comes only once in a lifetime.  I offered the lady marriage, but she refused it on the grounds that such a match might mar my career.  Had she lived, I would certainly never have married anyone else.  She died, and left this one child, whom for her sake I have cherished and cared for.  I could not acknowledge the paternity to the world, but I gave him the best of educations, and since he came to manhood I have kept him near my person.  He surprised my secret, and has presumed
