New York: Bantam, 1958. Paperback. 168p., very good first mass-market paperback edition in pictorial wraps featuring, in vignette, a production still of Orson Welles.
Originally published by Dodd, Mead in 1956 as "Badge of Evil" This Bantam paperback was issued to coincide with the release of the Orson Welles film. The novel and film bear little resemblance to each other.
