Richard Diamond, Private Detective proved to be the perfect radio vehicle for actor-singer Dick Powell, combining his tough-guy image, showcased in the 1944 film ÃïïMurder, My SweetÃïï and the 1945-46 radio series ÃïïRogueÃïïs Gallery,Ãïï with his tremendous talent for a song, as all those 1930s Warner Brothers/Fox musicals will bear out. The detective series, created by an aspiring screenwriter named Blake Edwards, featured a hard-boiled detective who rarely took himself too seriously; Edwards, the future director of the ÃïïPink PantherÃïï film series, conceived the Diamond character as an ex-cop who had decided to hang out his own shingle in the investigation business.
