We're rubbing elbows with four members of the fraternity of radio private detectives as they risk life and limb for their fee (plus expenses). Jeff Chandler stars as Michael Shayne in the syndicated mystery "The Pursuit of Death;" as Sam Spade, Howard Duff finds himself saddled with a partner and a bunny costume in "The Flopsy, Mopsy, and Cottontail Caper" (originally aired on CBS on December 4, 1949); Gerald Mohr stars as Philip Marlowe in "The Face to Forget" (originally aired on CBS on June 14, 1950); and Dick Powell sings and solves his way through "The Dixon Case" in Richard Diamond, Private Detective (originally aired on ABC on March 14, 1952).
