“It all came back to something I’d figured out once about the detective business. There were two ways to go along: underground or on top. I never found out which was best. Underground you had the element of surprise on your side, but it was harder to move around. On top you went everywhere, taking cracks at everybody, and everybody taking cracks at you. You had to be tough to play it that way. Well, I was tough.”
