Characters

 * Detective Nikki Heat is the lead character in Richard Castle's Nikki Heat book series. Heat is loosely based on NYPD detective Kate Beckett, possessing a similar backstory, in that her decision to become a detective was motivated by the death of someone close to her - although Heat has a niece and siblings that Beckett lacks - and the first case she investigates is adapted from several real cases Castle helped Beckett solve. Heat is assisted by her partner and sometime lover, journalist Jameson Rook. In addition, her colleagues Detectives Raley and Ochoa also work with her on cases.
 * Jameson Rook is a fictional character that Richard Castle created for his Nikki Heat series of crime novels. He is a famous magazine journalist who shadows the main character, Detective Nikki Heat, as well as her on-again off-again love interest. The character moonlights as a romance novelist under the pen name Victoria St. Clair. He is based on Castle himself and the way he works with Kate Beckett. ("Nikki Heat")
