He took up the lock of hair which had fallen out of the envelope. Was it possible that it could be his wife's, the Duchess? Was it possible that a Duchess of Datchet could be kidnapped, in broad daylight, in the heart of London, and be sent home, as it were, in pieces? Had sacrilegious hands already been playing pranks with that great lady's hair? Certainly, _that_ hair was so like _her_ hair that the mere resemblance made his Grace's blood run cold. He turned on Messrs. Barnes and Moysey as though he would have liked to rend them: "You scoundrels!" He moved forward as though the intention had entered his ducal heart to knock his servants down. But, if that were so, he did not act quite up to his intention. Instead, he stretched out his arm, pointing at them as if he were an accusing spirit: "Will you swear that it was the Duchess who got into the carriage outside Cane and Wilson's?" Barnes began to stammer: "I--I'll swear, your Grace, that I--I thought----" The Duke stormed an interruption: "I don't ask what you thought. I ask you, will you swear it was?" The Duke's anger was more than Barnes could face. He was silent. Moysey showed a larger courage: "Could have sworn that it was at the time, your Grace. But now it seems to me that it's a rummy go." "A rummy go!" The peculiarity of the phrase did not seem to strike the Duke just then--at least, he echoed it as if it didn't. "You call it a rummy go! Do you know that I am told in this letter that the woman who had entered the carriage was not the Duchess? What you were thinking about, or what case you will be able to make out for yourselves, you know better than I; but I can tell you this--that in an hour you will leave my service, and you may esteem yourselves fortunate if, to-night, you are not both of you sleeping in gaol. Knowles! take these men to a room, and lock them in it, and set some one to see that they don't get out of it, and come back at once. You understand, at once--to me!" Knowles did not give Messrs. Barnes and Moysey a chance to offer a remonstrance, even if they had been disposed to do so. He escorted them out of the room with a dexterity and a celerity which did him credit, and in a remarkably short space of time he returned to the ducal presence. He was the Duke's own servant--his own particular man. He was a little older than the Duke, and he had been his servant almost ever since the Duke had been old enough to have a servant of his very own. Probably James Knowles knew more than any living creature of the Duke's "secret history"--as they call it in the _chroniques scandaleuses_--of his little peculiarities, of his strong points, and his weak ones. And, in the possession of this knowledge, he had borne himself in a manner which had caused the Duke to come to look upon him as a man in whom he might have confidence--that confidence which a penitent has in a confessor--to look upon him as a trusted and a trustworthy friend.
