When viewers first met Richard Castle -- a famous mystery novelist and divorced father raising his teenage daughter -- he was creatively blocked. But when the NYPD questioned him in connection with murders staged to imitate crime scenes from his books, Castle found inspiration in NYPD Detective Kate Beckett, a bright and aggressive homicide detective with a fascination for odd and offbeat cases stemming from the unsolved murder of her own mother. Sparks began to fly, leading both to danger and a hint of romance as Castle stepped in to help find the copycat killer. With Beckett as his muse, Castle used his newfound experience in the field as fodder for his latest novel and bestseller, Heat Wave.
