The Prowler (1951)

Like The Bicycle Thief, this film has you questioning to whom the titular character is referring. Evelyn Keyes is a woman who gets more than she bargained for when she calls the police after seeing a prowler outsider her bathroom window. The story takes some interesting twists and turns from Los Angeles to an old abandoned mining town. There’s also a rather creepy Van Heflin as one of the officers who arrive to investigate the prowling. Unfortunately, Keyes’s character is a bit of a dope whose motivations don’t make a whole lot of sense which brings the intrigue down a notch.
