Mystery Mile

On the US side the Doubleday/Crime Club book-club tells are the ones to check and are well documented: "Book Club Edition" printed at the foot of the front jacket flap or no price at the flap at all, a blind stamp debossed into the rear board near the spine, and a five-digit code in a white block on the jacket rear. Crime Club book-club copies are common for this title and are routinely offered as firsts. The Heinemann, London, 1966 issue and the Penguin/Felony & Mayhem issues are later reprints, not first editions.
