->''"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 ''Moonlighting'' and ''Murder, She Wrote'', albeit served with a generous helping of ''Law & Order'' 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 most famous 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.

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]].
