When viewers first met Richard Castle -- a famous mystery novelist and divorced father raising his teenage daughter, while being kept grounded by his Broadway diva mother -- he was creatively blocked. But when the NYPD questioned him in connection with a series of murders staged to imitate crime scenes from his books, Castle found inspiration in Detective Kate Beckett, a bright and aggressive homicide cop with a fascination for odd and offbeat cases stemming from the years-old unsolved murder of her own mother.
Though they instantly clashed, sparks of another sort began to fly, leading both to danger and a hint of romance as Castle stepped in to help find the copycat killer. Once that initial case was solved, Castle and Beckett continued to investigate strange homicides in New York, combining Castle's writer intuition and Beckett's creative detective work. Then, after four seasons of “will they” or “won’t they,” Castle and Beckett finally gave into their feelings for each other. The fun and conflict continue to escalate as the crime-solving dynamic duo navigate a whole new chapter in their relationship.
