Sam Spade - Dashiell Hammett's San Francisco shamus of The Maltese Falcon - was a hit with audiences when he came to radio in July 1946. The mix of tongue in cheek comedy with hard-boiled mystery, combined with the memorable performance of Howard Duff in the title role, made for a series that still holds up today and stands as one of the very best the era had to offer. We'll hear Duff as Spade in "The Missing Newshawk Caper" (originally aired on CBS on July 18, 1948) and "The Vaphio Cup Caper" (originally aired on CBS on August 22, 1948). Then Steve Dunne steps into Sam's shoes for "The Chateau McLeod Caper" (originally aired on NBC on January 26, 1951).
