“Everything,” exclaimed the voice of Mr Verloc, and then sank very low.

After a while it rose again.

“You have known me for several years now, and you’ve found me useful, too. You know I was a straight man. Yes, straight.”

This appeal to old acquaintance must have been extremely distasteful to the Chief Inspector.

His voice took on a warning note.

“Don’t you trust so much to what you have been promised. If I were you I would clear out. I don’t think we will run after you.”

Mr Verloc was heard to laugh a little.

“Oh yes; you hope the others will get rid of me for you—don’t you? No, no; you don’t shake me off now. I have been a straight man to those people too long, and now everything must come out.”

“Let it come out, then,” the indifferent voice of Chief Inspector Heat assented. “But tell me now how did you get away.”

“I was making for Chesterfield Walk,” Mrs Verloc heard her husband’s voice, “when I heard the bang. I started running then. Fog. I saw no one till I was past the end of George Street. Don’t think I met anyone till then.”
