Howard Duff was one of radio's brightest stars until the blacklist and "Red scare" paranoia derailed his career. Today, he's fondly remembered as the definitive voice of Sam Spade with the perfect blend of tough guy delivery and wry humor. We'll hear Duff as Spade in "The Death Bed Caper," originally aired on CBS on June 20, 1948. Then, he stars as Mike McCoy, a private eye cut from the Spade cloth in the 1951 audition program for The McCoy.
