Perhaps the only radio detective star to have actually worked as a real-life private eye, William Gargan played several gumshoes on the air, as well as the big and small screens. He was most famous on radio as Barrie Craig, Confidential Investigator but he gave voice to other hard-boiled private eyes with wry senses of humor. Today, William Gargan stars as two of those old time radio crime-solvers. First, he's Ross Dolan, ex-sailor and shamus in I Deal in Crime. We'll hear him in the premiere episode of that series (originally aired on ABC on January 21, 1946). Then he's Barrie Craig in "The Sneak Assassin" (originally aired on NBC on November 21, 1954).
