Debuting in 1930, the radio show was originally called Detective Story, and later renamed The Shadow. In 1931, magician and writer Walter Gibson began writing The Shadow pulp magazine. From 1937-8, a young Orson Welles voiced the Shadow.
Who was The Shadow? He was Lamont Cranston (sometimes), . “...a man of mystery who strikes terror in the very souls of sharpsters, lawbreakers and criminals.”
