The Lives of Harry Lime was a British radio series that followed the misadventures of its title character Harry Lime, a con-artist portrayed by Orson Welles. This character was reprised from the 1949 cult movie, The Third Man, and the radio series was set before the events in the film. Most episodes opened with a haunting theme by Anton Karas, followed by a gunshot, and then an introduction by Welles as Harry Lime. Being the first independently-produced series that the BBC ever broadcasted, it inspired a Pocket Book of short stories based on scripts, some of which were reportedly written by Orson Welles himself.

The show aired from 1951-1952, and although the BBC only acquired sixteen of the series' fifty-two episodes, it gained a following for its unique storylines that followed Lime's adventures around the world. These adventures included continent hopping, skirt chasing, pick pocketing, breaking and entering, and playing patsy. However, Lime had a conscience, and drew the line at blackmail and murder. Several episodes featured plot elements that Welles later expanded upon in the 1955 motion picture Mr. Arkadin.
