The Death Triangle

This episode of The Shadow was originally broadcast on December 12, 1937.
"Who knows what evil lurks in the hearts of men? The Shadow knows!" From 1930-1954, the wealthy Lamont Cranston was one of the best-known characters on radio, using his mystical powers to fight crime. The only person who knew The Shadow's true identity was his "friend and companion, the lovely Margot Lane". Through the years, The Shadow was portrayed by Frank Readick, Orson Welles, Bill Johnstone, Bret Morrison, and others. As listeners were reminded at the end of every episode, "The weed of crime bears bitter fruit. Crime does not pay! The Shadow knows!"
