The Shadow

'Who knows what evil lurks in the heart of men? - The Shadow knows!'

The Shadow is a collection of serialized dramas, originally on 1930s radio and then in a wide variety of media, that follow the exploits of the title character, a crime-fighting vigilante with psychic powers.2 One of the most famous pulp heroes of the 20th century, The Shadow has been featured in comic books, comic strips, television, video games, and at least five motion pictures. The radio drama is well-remembered for those episodes voiced by Orson Welles.
