"Or at any rate that you have seen him since any of us. He professes not to care a straw for Mountjoy or his whereabouts, and declares himself under obligation to those who have contrived his departure. Nevertheless, he is curious." "What have I to do with Mountjoy Scarborough?" "That's just the question. What have you to do with him? He suggests that there have been words between you as to Florence, which has caused Mountjoy to vanish. I don't profess to explain anything beyond that,--nor, indeed, do I profess to agree with my father. But the odd thing is that Prodgers, the policeman, has the same thing running in his head." "Because I have shown some anxiety about your brother in Scotland Yard." "No doubt; Prodgers says that you've shown more anxiety than was to be expected from a mere acquaintance. I quite acknowledge that Prodgers is as thick-headed an idiot as you shall catch on a summer's day; but that's his opinion. For myself, I know your word too well to doubt it." Harry walked on in silence, thinking, or trying to think, what, on the spur of the moment, he had better do. He was minded to speak out the whole truth, and declare to himself that it was nothing to him what Augustus Scarborough might say or think. And there was present to him a feeling that his companion was dealing unfairly with him, and was endeavoring in some way to trap him and lead him into a difficulty. But he had made up his mind, as it were, not to know anything of Mountjoy Scarborough, and to let those five minutes in the street be as though they had never been. He had been brutally attacked, and had thought it best to say nothing on the subject. He would not allow his secret, such as it was, to be wormed out of him. Scarborough was endeavoring to extort from him that which he had resolved to conceal; and he determined at last that he would not become a puppet in his hands. "I don't see why you should care a straw about it," said Scarborough. "Nor do I." "At any rate you repeat your denial. It will be well that I should let my father know that he is mistaken, and also that ass Prodgers. Of course, with my father it is sheer curiosity. Indeed, if he thought that you were keeping Mountjoy under lock and key, he would only admire your dexterity in so preserving him. Any bold line of action that was contrary to the law recommends itself to his approbation. But Prodgers has a lurking idea that he should like to arrest you." "What for?" "Simply because he thinks you know something that he doesn't know. As he's a detective, that, in his mind, is quite enough for arresting any man. I may as well give him my assurance, then, that he is mistaken." "Why should your assurance go for more than mine? Give him nothing of the kind." "I may give him, at any rate, my assurance that I believe your word." "If you do believe it, you can do so." "But you repeat your assertion that you saw nothing of Mountjoy just before his disappearance?"
