The Shadow - Old time Radio
A figure never seen, only heard, the Shadow was an invincible crime fighter. He possessed many gifts which enabled him to overcome any enemy. Besides his tremendous strength, he could defy gravity, speak any language, unravel any code, and become invisible with his famous ability to "cloud men's minds." Along with his team of operatives, the Shadow battled adversaries with chilling names like The Black Master, Kings of Crime, The Five Chameleons, and, of course, The Red Menace.
