Castle is an American crime mystery comedy-drama television series[1] that aired on ABC for a total of eight seasons from March 9, 2009, to May 16, 2016.

Created by Andrew W. Marlowe, it primarily traces the lives of Richard Castle (Nathan Fillion), a best-selling mystery novelist, and Kate Beckett (Stana Katic), a homicide detective, as they solve various unusual crimes in New York City.

The overarching plot of the series focused on the romance between the two lead characters and their ongoing investigation of the murder of Beckett's mother.

On May 12, 2016, it was announced that despite some cast members signing one-year contracts for a potential ninth season, the show had been canceled.

Bored and suffering from writer's block, he kills off Derrick Storm, the main character in his successful book series.

He is brought in by the New York Police Department for questioning regarding a copycat murder based on one of his novels, where he meets and becomes intrigued by Detective Kate Beckett (Katic), the officer assigned to the case.

However, as Beckett begins to appreciate Castle's assistance in helping her catch killers, the two eventually become friends and then lovers.

Their cases often deal with murders occurring within various unusual subcultures or milieus, including reality TV shows, vampire enthusiasts, a science-fiction convention, and a man who claims to be a time traveler.

A recurring plotline deals with the unsolved murder of Beckett's mother years before, an investigation that leads to an increasingly sprawling and dangerous conspiracy.

Real-life writers Stephen J. Cannell, James Patterson, Dennis Lehane, and Michael Connelly appear as themselves during periodic games of poker at Castle's apartment.
