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,

"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
check."

Never shall I forget the Duke's appearance as he sprang up and clawed
with his hands, like one who is sinking into an abyss. Then, with an
extraordinary effort of aristocratic self-command, h
