Castle is an American television drama that aired on ABC from March 9, 2009 to May 16, 2016.

The series was officially cancelled on May 12, 2016, after eight seasons and 173 episodes.


"Castle" follows Nathan Fillion as Richard Castle, a famous mystery novelist who has killed off the main character in his book series and has writer's block. He is brought in by the NYPD for questioning regarding a copy-cat murder based on one of his novels.

He is intrigued by this new window into crime and murder, and uses his connection with the Mayor to charm his way into shadowing Detective Kate Beckett, played by Stana Katic. Castle decides to use Beckett as the model for Nikki Heat, the main character of his next book series. Beckett, an avid reader of Castle's books, initially disapproves of having Castle shadow her on her cases, but later warms up and recognizes Castle as a useful resource in her team's investigations.

The overarching plot of the series focuses on the romance between the two lead characters, as well as the murder of Beckett's mother.
