Silver Streak is a life tenancy, an' the London and Denver have got second option. See? This Duke felly got it in his own name, so when he goes to glory, in steps the imperishable London an' Denver Corporation—that's youse."

"The suggestion you make is infamous, and I must solemnly and emphatically place on record my complete and absolute disapproval of your reasoning. I do not know whether it is not my duty to inform the police of your threat—for it is a threat—to create—er—a breach of the peace."

"I content myself by saying that I dissociate myself from any private scheme of vengeance you may contemplate against the Duc de Montvillier."

Bill's eyes closed wearily.

"You make me tired," he said simply.
