It's a birthday party for Dick Powell, but instead of cake we've got four old time radio mysteries starring the singing star turned film noir leading man and radio gumshoe. First, he co-stars with his then-wife Joan Blondell in the comedy-mystery Miss Pinkerton, Inc. (originally aired on CBS on July 12, 1941). Next, Powell is private eye Richard Rogue in Rogue's Gallery. We'll hear "Suspicious Will aka Anson Leeds is Dead" (originally aired on Mutual on January 17, 1946). Then, as Richard Diamond, Private Detective, he solves "The Cover-up Murders aka The Eight O'Clock Killer" (originally aired on CBS on June 7, 1953). Finally, Powell plays "the man with the action-packed expense account" in the 1948 audition recording for Yours Truly, Johnny Dollar.
