THE WHISPERING SHADOW (1933)--a 12-chapter colorized serial in one video

A mysterious criminal known as The Whispering Shadow commits crimes by means of a gang he controls by television and radio rays. Jack Norton, whose brother was murdered by The Whispering Shadow, suspects that the eerie Professor Strang - whose ghostly wax museum contains figures far too lifelike - may be involved in the crimes. However, the Whispering Shadow is an underworld mastermind. He has invented a device that allows him to kill by radio control. He, along with several other persons, seeks the late Russian Czar's jewels. The serial is notable for the constant false clues and decoy actions that make nearly everybody a suspect.
