"Are you serious, sir?"
"I mean what I say, if that's what you are asking, Mr Nunn."
"Then what about the tale that girl was telling, and that knife she saw?"
"That knife is mine."
"Yours!"
"Exactly, and I'm afraid that knife is going to hang me."
"How came it in Miss Arnott's possession?"
"That's the simplest part of the whole affair. After I had used it she found it, and has kept it ever since."
"Do you mean that she's been screening you?"
"Something like it. That is, I don't know that she was sure of anything; but, I fancy, she has had her doubts. I daresay she'll tell you all about it if you ask her. You see, Mr Nunn, I've been in rather an awkward position. So long as it was only a question of Jim Baker it didn't so much matter; it's quite on the cards that in the course of his sinful career he's done plenty of things for which he deserves to be hung. When it comes to Miss Arnott, knowing that she knows what she does know, and especially that she has that accursed knife of mine, that's a horse of a different colour. Since she has only to open her mouth to make an end of me, I may as well make as graceful an exit as possible, and own the game is up. I don't quite know what is the usual course in a matter of this sort, Mr Nunn. My motor is outside. If it is possible I should like to run over to my house. You may come with me, if you please, and Mr Granger also. There are one or two trifles which require my personal attention, and then you may do with me as you please. In fact, if you could manage to let me have an hour or two I should be happy to place at your disposal quite a little fortune, Mr Nunn and Mr Granger."
