->''"I often say that'' Castle ''is'' {{Series/Moonlighting}} ''meets'' Series/MurderSheWrote ''having not really remembered ''Moonlighting'' and never having actually seen ''Murder She Wrote''."''
-->-- '''Creator/NathanFillion''' as quoted [[http://www.youtube.com/watch?v=NQKZ5r4QIak&NR=1#t=00m49s here]]

''Castle'' is a PoliceProcedural {{dramedy}} starring Creator/NathanFillion and Creator/StanaKatic. It really can be seen as a [[XMeetsY combination]] of ''Series/{{Moonlighting}}'' and ''Series/MurderSheWrote'', albeit served with a generous helping of ''Series/LawAndOrder'' and seasoned liberally with Nathan Fillion's natural wise-ass charm.

Fillion plays famous mystery novelist Richard Castle[[note]]An {{Expy}} of horror/suspense novelist Creator/StephenKing, according to WordOfGod[[/note]], who begins the series having killed off his main character and suffering from a severe case of writer's block.

After a killer begins to recreate murder scenes from Castle's books, Castle is consulted by Detective Kate Beckett (Katic) of the NYPD. When an obsessive fan is arrested far too quickly and easily, it bothers his [[GenreSavvy writer's sensibilities]], convincing him that the fan was framed and helping Beckett to catch the ''real'' murderer.

Enamored with using his knowledge of criminal methodology to solve real crimes (and a bit more enamored with Beckett, who becomes the inspiration for his next main character), Castle pulls some strings and gets permission to work alongside Beckett and the NYPD as [[ItsForABook "research"]] for his next book. With Castle's [[SherlockScan analytical instincts]] (and over-active imagination) and Beckett's years of experience, TheyFightCrime.

Two of Rick Castle's works in the show have been {{defictionalized}}, the ''Literature/NikkiHeat'' novels and the ''ComicBook/DerrickStorm'' comic book adaptation.

In 2016, ABC reported that the show would not be renewed for a ninth season, after having previously reported that Stana Katic and Tamala Jones (who played ME Lanie Parrish) were not offered their parts back if there were a ninth season.

The series finale aired on May 16, 2016.

The show has a [[Recap/{{Castle}} recap]] page, a [[ShoutOut/{{Castle}} shout out]] page, and [[WikiRule its own]] [[http://castle.wikia.com/wiki/Castle_Wiki wiki]].
