“He failed you this time.”

“Neither had I wind of anything in any other way,” retorted Chief Inspector Heat. “I asked him nothing, so he could tell me nothing. He isn’t one of our men. It isn’t as if he were in our pay.”

“No,” muttered the Assistant Commissioner. “He’s a spy in the pay of a foreign government. We could never confess to him.”

“I must do my work in my own way,” declared the Chief Inspector. “When it comes to that I would deal with the devil himself, and take the consequences. There are things not fit for everybody to know.”

“Your idea of secrecy seems to consist in keeping the chief of your department in the dark. That’s stretching it perhaps a little too far, isn’t it? He lives over his shop?”

“Who—Verloc? Oh yes. He lives over his shop. The wife’s mother, I fancy, lives with them.”

“Is the house watched?”

“Oh dear, no. It wouldn’t do. Certain people who come there are watched. My opinion is that he knows nothing of this affair.”

“How do you account for this?” The Assistant Commissioner nodded at the cloth rag lying before him on the table.

“I don’t account for it at all, sir. It’s simply unaccountable. It can’t be explained by what I know.” The Chief Inspector made those admissions with the frankness of a man whose reputation is established as if on a rock. “At any rate not at this present moment. I think that the man who had most to do with it will turn out to be Michaelis.”
