The Invisible Ghost

Dr. Charles Kessler (Bela Lugosi), a well-to-do physician who shares his mansion with his daughter, Virginia (Polly Ann Young), has been depressed ever since his wife (Betty Compson) left him for another man, only to later die in a car accident. That's not all Kessler has to worry about, however. Unexplained murders have begun to occur around town, eventually claiming members of his house staff. Making matters worse, the authorities suspect Kessler may somehow be involved.
