"The Falcon" radio series premiered on the Blue Network April 10, 1943, and continued playing on NBC and Mutual until 1954. "The Falcon" was loosely based on the series of popular Falcon movies distributed by RKO. The Falcon was an alternate identity for detective Michael Waring. Like the Falcon movies, the radio plots mixed danger, romance and comedy in equal parts. Each show began with a telephone ringing and Michael Waring, The Falcon, answering the phone. Speaking with a woman whose voice was never heard, Waring would explain that he had an urgent situation in which he had to deal with. This led into the standard opening, followed by the week's tale of adventure. Often, incompetent police were unable to solve the mysteries without his help. Originally sponsored by Gem Razor Blades, Waring was billed on radio as a freelance detective who was "always ready with a hand for oppressed men and an eye for repressed women". Berry Kroeger, James Meighan, Les Tremayne, Les Damon and George Petrie portrayed The Falcon over the radio run.
