Unforgettable villainy. Suspenseful and very frightening, thanks to Robert Mitchum's lethally threatening performance and the frightened reactions of a pro cast. Sexual deviate and lethal psychopath Mitchum is released from prison after serving a six-year term for rape and assault. He is bent on revenge against Peck, the witness whose testimony put him there, who is a family man and a lawyer with a private practice in Florida. When Peck learns Mitchum is in town, he goes to Balsam, the sheriff, who tries to make life miserable for Mitchum until a lawyer threatens to file suit on charges of harassment. Peck's dog is poisoned, then Mitchum takes to the phone, calling Bergen, the lawyer's wife, plaguing her with obscene remarks. Though he makes no overt threats, he intimates a dire fate for the family, including their teenage daughter, Martin. Because the police are helpless to jail the lunatic and the calls and oblique threats continue, Peck decides to handle matters himself. J. Lee Thompson directs at a clip, until the crawl toward the bayou climax, where the minutes feel like hours, and your heart sits in your throat. Peck is careful not to act the fear; he's an interesting foe for Mitchum. Bergen's performance reminds one that she should have been a bigger star, given her beauty and undeniable talent, and Martin recalls an era when teenagers really were innocent. Balsam, Savalas, and Chase contribute effective cameos. The musical score by Bernard Herrmann is a nerve-beater.
