When Dashiell Hammett put pen to paper, he forever changed the genre of detective fiction. He created characters and stories that popularized the hard-boiled school, and those tales still entertain readers today. Hammett's works were adapted for successful films, television shows, and radio dramas. In this birthday salute to the author, we'll hear a pair of radio mysteries starring his master private detective Sam Spade: "The Quarter-Eagle Caper" starring Howard Duff (AFRS rebroadcast from November 28, 1948) and "The Shot in the Dark Caper" with Steve Dunne (originally aired on NBC on February 23, 1951). Plus, we'll hear a Suspense adaptation of Hammett's short story "Two Sharp Knives" (originally aired on CBS on December 22, 1942).
