Although Sam Spade is perhaps the most famous of all hard-boiled detectives, creator Dashiell Hammett only featured the character in a single novel, The Maltese Falcon, and three short stories. Spade burst onto the airwaves in 1946, portrayed to cynical perfection by Howard Duff with Lurene Tuttle costarring as his secretary, Effie Perrine. Radio Spirits proudly presents 17 detective classics, including "The Kandy Tooth," a special hour-long Sam Spade adventure that aired on Suspense, "radio's outstanding theater of thrills."
