Holmes's cold and inexorable manner showed the secretary that it was useless to argue with him. "Very good, Mr. Holmes; I will tell him that you are here." After half an hour's delay the great nobleman appeared. His face was more cadaverous than ever, his shoulders had rounded, and he seemed to me to be an altogether older man than he had been the morning before. He greeted us with a stately courtesy and seated himself at his desk, his red beard streaming down on to the table. "Well, Mr. Holmes?" said he. But my friend's eyes were fixed upon the secretary, who stood by his master's chair. "I think, your Grace, that I could speak more freely in Mr. Wilder's absence." The man turned a shade paler and cast a malignant glance at Holmes. "If your Grace wishes----" "Yes, yes; you had better go. Now, Mr. Holmes, what have you to say?" My friend waited until the door had closed behind the retreating secretary. "The fact is, your Grace," said he, "that my colleague, Dr. Watson, and myself had an assurance from Dr. Huxtable that a reward had been offered in this case. I should like to have this confirmed from your own lips." "Certainly, Mr. Holmes." "It amounted, if I am correctly informed, to five thousand pounds to anyone who will tell you where your son is?" "Exactly." "And another thousand to the man who will name the person or persons who keep him in custody?" "Exactly." "Under the latter heading is included, no doubt, not only those who may have taken him away, but also those who conspire to keep him in his present position?" "Yes, yes," cried the Duke, impatiently. "If you do your work well, Mr. Sherlock Holmes, you will have no reason to complain of niggardly treatment." My friend rubbed his thin hands together with an appearance of avidity which was a surprise to me, who knew his frugal tastes. "I fancy that I see your Grace's cheque-book upon the table," said he. "I should be glad if you would make me out a cheque for six thousand pounds. It would be as well, perhaps, for you to cross it. The Capital and Counties Bank, Oxford Street branch, are my agents." His Grace sat very stern and upright in his chair, and looked stonily at my friend. "Is this a joke, Mr. Holmes? It is hardly a subject for pleasantry." "Not at all, your Grace. I was never more earnest in my life." "What do you mean, then?" "I mean that I have earned the reward. I know where your son is, and I know some, at least, of those who are holding him." The Duke's beard had turned more aggressively red than ever against his ghastly white face. "Where is he?" he gasped. "He is, or was last night, at the Fighting Cock Inn, about two miles from your park gate." The Duke fell back in his chair. "And whom do you accuse?" Sherlock Holmes's answer was an astounding one. He stepped swiftly forward and touched the Duke upon the shoulder. "I accuse _you_," said he. "And now, your Grace, I'll trouble you for that cheque."
