The Whistler was an American radio mystery drama series that aired from May 16, 1942, to September 22, 1955, on the west-coast regional CBS radio network. The eerie show followed a mysterious character known as the Whistler, an unseen observer and narrator of crimes and fateful events. The stories typically revolved around criminal acts being revealed by overlooked details or the criminal's own folly, with an ironic and often grim ending. Bill Forman played the title role for the longest period, with actors like Gale Gordon, Joseph Kearns, Marvin Miller, and Bill Johnstone also portraying the Whistler. The series was possibly inspired by The Shadow and was also adapted into a film noir series by Columbia Pictures in 1944 and a brief syndicated TV version in 1954.
