Tennis pro Guy Haines is in a bad marriage when he’s approached by a perfect stranger, Bruno (Robert Walker), who idly contemplates the perfect murder. Bruno speculates that if he gets Guy’s wife out of the way, then Guy could take care of Bruno’s untenable father and each could have an alibi for the murder they’d be suspected of and no discernable motive for the crime they committed. “Bruno’s manner is pushy and insinuating, with homoerotic undertones . . . not a psychological study, however, but a first-rate thriller with odd little kinks now and then.”—Roger Ebert.
