Sam Spade

The Adventures of Sam Spade was a radio series based (loosely) on the private detective character Sam Spade created by writer Dashiell Hammett for The Maltese Falcon. It was the rare show that ran on all three networks during the years from 1946 through 1951. The series starred Howard Duff (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.
