The big screen and best-seller worlds collide this week when Glenn Ford and Erle Stanley Gardner team up to bring you Christopher London. Ford stars as the globe-trotting private detective created by Gardner, the author behind Perry Mason. In this short-lived series (curtailed by Ford's success in Hollywood), London takes cases all around the world and finds danger wherever he goes. We'll hear him in "The Adventure of the Emerald Ring," originally aired on NBC on February 5, 1950.
