Dr. Marion McGregor is remarrying after the death of her first husband. That's when she starts receiving threatening phone calls. Her new husband Roger Harden tries to protect her and even buys a gun but the calls continue. He eventually convinces her to calls the police after they find a slaughtered doberman in their bed. A friendly police lieutenant shows up and checks the house including the wine cellar for intruders but finds nothing. Marion suspects her dead husband and lieutenant agrees that it could be him, since his body was never found after the car crash that supposedly killed him. With pragmatic cynicism he suggests that they should buy a gun. During a book signing event where Marion is promoting her new book, a creepy stranger appears and terrifies her, so she runs away. He tries to pursue her but fails. When she arrives home, she freaks out and arms herself with a fire poker. Roger arrives later and hears noises from the cellar. The story ends with a shocking twist.
