"The best I ever met," old Mendel, the Superintendent's one-time superior, had told him over a friendly pint not long ago. Mendel was retired now, like Smiley. But Mendel knew what he was talking about and didn't like Funnies any better than the Superintendent did—interfering la-di-da amateurs most of them, and devious with it. But not Smiley. Smiley was different, Mendel had said. Smiley was the best—simply the best case man Mendel had ever met—and old Mendel knew what he was talking about.
