It's a triple feature of the same mystery starring three different radio gumshoes. Morton Fine and David Friedkin wrote the story of a killer who taunts police with announcements of his upcoming crimes, and the clever tale comes to life in three similar but different adventures. First, Lt. Danny Clover investigates "The Jane Darnell Murder Case" on Broadway is My Beat (originally aired on CBS on August 11, 1949). Then, in London, Inspector Peter Black stars in "Three for All" from Pursuit (originally aired on CBS on November 10, 1949). Finally, Howard Duff plays L.A. gumshoe Mike McCoy in the audition recording for what would have been The McCoy (recorded on or around April 24, 1951).
