Pat Novak, for Hire is an old-time radio detective drama series which aired from 1946–1947 as a West Coast regional program and in 1949 as a nationwide program for ABC. The regional version originally starred Jack Webb in the title role, with scripts by his roommate Richard L. Breen. When Webb and Breen moved from San Francisco to Los Angeles to work on an extremely similar nationwide series, Johnny Madero, Pier 23, for the Mutual network, Webb was replaced by Ben Morris and Breen by other writers. In the later 1949 network version, Jack Webb resumed the Novak role, and Breen his duties as scriptwriter. The series is popular among fans for its fast-paced, hard-boiled dialogue and action and witty one-liners.
