What do Philo Vance, George Valentine, Richard Diamond, and John J. Malone have in common? They all romanced – and were frequently assisted by – Frances Robinson. The busy and talented actress was a mainstay on radio crime dramas, and her performances gave us some of the genre's all-time great partners in crime. We'll hear her in "The Elusive Hundred Grand" from Let George Do It (originally aired on Mutual on April 18, 1949); "The Pop Skoals Case aka The Blind Man and the Cop Killer" from Richard Diamond, Private Detective (originally aired on NBC on February 26, 1950), and in "Murder in Mind" from The Whistler (originally aired on CBS on April 16, 1950).
