Nick and Catherine begin a torrid affair with the air of a cat-and-mouse game. Nick arrives at a club and witnesses Catherine doing cocaine with Roxy and another man. Nick and Catherine dance and make out, and are later observed by Roxy, having violent sex in Catherine's bed. Catherine ties Nick to the headboard with a white silk scarf, just as Boz was tied by the mystery blonde, but does not kill him. Roxy, jealous of Nick, attempts to run him over with Catherine's car, but dies when the car crashes. Catherine grieves over Roxy's death and tells Nick about a previous lesbian encounter at college that went awry. She claims that the girl became obsessed with her, causing Nick to believe that Catherine may not have killed Boz. Nick identifies the girl as Beth, who acknowledges the encounter, but she claims it was Catherine who became obsessed. Additionally, Nick discovers that a college professor of Beth and Catherine's was also killed with an ice pick in an unsolved homicide, and that the events inspired one of Catherine's early novels.
