Basic Instinct
Plot
Catherine is uncooperative with the investigators, taunting them by smoking during questioning and exposing herself. Though released for lack of evidence, she becomes a person of interest when Nick learns that she has a history of close relationships with violent individuals. These include her girlfriend Roxanne "Roxy" Hardy, who killed her younger brothers as a teenager, and Hazel Dobkins, a convicted family murderer.
Plot
At Boz's nightclub, Nick sees Catherine and Roxy using cocaine. Later, at Catherine's home, she ties Nick to the bed during sex while Roxy watches. Moran expresses concern about Nick's involvement with Catherine and uncovers that Nilsen received a $50,000 payment months before Nick met her.
Plot
Roxy, jealous of Nick, attempts to kill him in a car attack but dies in the ensuing crash. Catherine reveals that she had an intense relationship with a woman in college who became obsessed with her. Nick suspects the woman was Garner, who claims the obsession went the other way. Investigating further, Nick finds that Nilsen had withdrawn a complaint Catherine filed against Garner years earlier. He also uncovers that a professor shared by Garner and Catherine was killed with an ice pick in an unsolved case resembling Catherine's fiction, and that Garner's former husband was murdered in another unresolved case investigated by Nilsen.
