“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 surmised my secret, and has presumed ever since upon the claim which he has upon me, and upon his power of provoking a scandal which would be abhorrent to me. His presence had something to do with the unhappy issue of my marriage. Above all, he hated my young legitimate heir from the first with a persistent hatred. You may well ask me why, under these circumstances, I still kept James under my roof. I answer that it was because I could see his mother’s face in his, and that for her dear sake there was no end to my long-suffering. All her pretty ways too—there was not one of them which he could not suggest and bring back to my memory. I could not send him away. But I feared so much lest he should do Arthur—that is, Lord Saltire—a mischief, that I dispatched him for safety to Dr. Huxtable’s school.

“James came into contact with this fellow Hayes, because the man was a tenant of mine, and James acted as agent. The fellow was a rascal from the beginning, but, in some extraordinary way, James became intimate with him. He had always a taste for low company. When James determined to kidnap Lord Saltire, it was of this man’s service that he availed himself. You remember that I wrote to Arthur upon that last day. Well, James opened the letter and inserted a note asking Arthur to meet him in a little wood called the Ragged Shaw, which is near to the school. He used the Duchess’s name, and in that way got the boy to come. That evening James bicycled over—I am telling you what he has himself confessed to me—and he told Arthur, whom he met in the wood, that his mother longed to see him, that she was awaiting him on the moor, and that if he would come back into the wood at midnight he would find a man with a horse, who would take him to her. Poor Arthur fell into the trap. He came to the appointment, and found this fellow Hayes with a led pony. Arthur mounted, and they set off together. It appears—though this James only heard yesterday—that they were pursued, that Hayes struck the pursuer with his stick, and that the man died of his injuries. Hayes brought Arthur to his public-house, the Fighting Cock, where he was confined in an upper room, under the care of Mrs. Hayes, who is a kindly woman, but entirely under the control of her brutal husband.

“Well, Mr. Holmes, that was the state of affairs when I first saw you two days ago. I had no more idea of the truth than you. You will ask me what was James’s motive in doing such a deed. I answer that there was a great deal which was unreasoning and fanatical in the hatred which he bore my heir. In his view he should himself have been heir of all my estates, and he deeply resented those social laws which made it impossible. At the same time, he had a definite motive also. He was eager that I should break the entail, and he was of opinion that it lay in my power to do so. He intended to make a bargain with me—to restore Arthur if I would break the entail, and so make it possible for the estate to be left to him by will. He knew well that I should never willingly invoke the aid of the police against him. I say that he would have proposed such a bargain to me, but he did not actually do so, for events moved too quickly for him, and he had not time to put his plans into practice.
