We wrap up our series of Hollywood stars who solved crimes on the air with Glenn Ford. The star of Gilda, The Big Heat, and 3:10 to Yuma appeared on radio as Christopher London, a globetrotting private eye created by Erle Stanley Gardner. We'll hear Ford as London in "The Missing Heiress" (originally aired on NBC on February 5, 1950). Then, he's a man on the run in a Studio One adaptation of "The 39 Steps" (originally aired on CBS on March 23, 1948).
