The Adventures of Sam Spade was a radio series based loosely on the private
detective character Sam Spade, created by writer Dashiell Hammett.The show
ran for 13 episodes on ABC in 1946, for 157 episodes on CBS in 1946-1949,
and finally for 51 episodes on NBC in 1949-1951.The series starred Howard
Duff (above) and later, Steve Dunne as Sam Spade and Lurene Tuttle as his
secretary Effie, and took a considerably more tongue-in-cheek approach to the
character than the novel or movie. In 1947, scriptwriters Jason James and Bob
Tallman received an Edgar Award for Best Radio Drama from the Mystery
Writers of America.
