For one hundred dollars a day plus expenses, Richard Diamond will tackle any case. By the time it's over, he'll have used his fists, his gun, his wits, and his pipes as he croons a tune to his girlfriend. Dick Powell stars as the singing detective in one of radio's best mystery shows. We'll hear him in a pair of episodes – "The Betty Moran Case" (originally aired on NBC on May 29, 1949) and "The Cathy Victor Case" (originally aired on January 15, 1950).
