TV Series created by Andrew W. Marlowe

Ella, the former star of a hit cop series, is fresh out of-rehab following a bender of epic proportion. Desperate to restart her career, she talks her way into shadowing rough-and-tumble private investigator Eddie as research for a potential comeback role. Though lone wolf Eddie resents the babysitting gig, high-spirited Ella proves herself to be surprisingly valuable, drawing on her acting skills and 200 episodes of playing a detective. When the press touts Ella's role in solving a high-profile case, Eddie finds his phone ringing off the hook with new clients looking to hire the pair.

Meet Richard Castle: he's a successful murder-mystery writer who has just killed off his main character. However, it seems one of his fans liked his books just a bit too much when a copycat murderer starts running around killing people as described in Castle's books.
