The Prowler

Webb Garwood (Van Heflin) is called to investigate a voyeur by Susan Gilvray (Evelyn Keyes) Her husband works nights as an overnight radio personality. Webb finds out about an insurance policy on the husband's life. He dreams up a scheme in which a phantom "prowler" would be a good scapegoat if Susan's husband should happen to die mysteriously. After becoming a prowler himself, Webb "investigates" and then commits the murder, making it look like a tragic accident in which he and the husband shot at each other.
