INVISIBLE GHOST

The home of Charles Kessler (Bela Lugosi) is beset by a series of unsolved murders. Kessler, who lives with his daughter and servants since his wife left him, is shown to be the murderer, unbeknownst to himself. His wife (Betty Compson), who became brain-damaged in a car accident not long after leaving him, has been visiting the grounds of the house and the sight of her through his window puts Kessler into a trance-like state which makes him homicidal. Ralph Dickson, the fiancée of Kessler's daughter, is convicted and executed for one of the murders. His twin brother Paul arrives and, through a series of events, including Kessler's wife finally entering the house and being seen by others, Kessler is seen to go into the trance and the mystery is revealed.
