Old Time Radio Detective - Sam Spade

All available episodes. The Adventures of Sam Spade (1946-1951) radio series was loosely based on the private detective character Sam Spade, created by writer Dashiell Hammett for The Maltese Falcon. Film star Howard Duff played Sam Spade (also played by Steve Dunne at the end). Lurene Tuttle played Effie, Spade's secretary. Spade's character was the prototypical "hard-boiled" detective - an introspective, sharp witted, tough guy.
