Sam Spade was a hard-boiled detective with cold detachment, a keen eye for detail, and unflinching determination to achieve his own justice. The character of Sam Spade was created by writer Dashiell Hammett in 1930 for his crime story The Maltese Falcon, and for most people, the character is closely associated with actor Humphrey Bogart, who played Sam Spade in the third and most famous film version of the story.In 1946 William Spier, one of radio's top producers, brought Sam Spade to the airwaves starring newcomer Howard Duff with Lurene Tuttle (and occasionally Sandra Gould) as Effie Perrine, Spade's secretary. Duff took a more tongue-in-cheek approach to the character than did the vel or movie. Dashiell Hammett lent his name to the radio series but did little more than cash the checks sent to him for the privilege.Scriptwriters were Jason James and Bob Tallman, who received an Edgar Award in 1947 for best radio drama from the Mystery Writers of America. Howard Duff starred as Spade until 1951 when Stephen Dunne took the role.
