Sam Spade made a dynamic debut in Dashiell Hammett's The Maltese Falcon before lighting up the big screen in John Huston's classic noir drama. In 1946, Spade came to radio in a weekly series of adventures that became a critical and listener favorite. We'll hear Howard Duff in "The Bail Bond Caper" (originally aired on CBS on June 27, 1948) and "The S.Q.P. Caper" (AFRS rebroadcast, originally aired on CBS on November, 1948). Then, Steve Dunne is Spade in "The Sure Thing Caper" (originally aired on NBC on February 9, 1951).
