Blind Catholic priest Arguello identifies the regular prayer murdered in his church as Castle's famously reclusive idol, a one-hit great American novel author. Becket reluctantly admits she needs Castle's author skills and city hall access to investigate the case, as the author's multiple pseudonyms 'for long participatory research purposes' including a mob hit-man lead to infidelity and city funds fraud, triggering new crimes. Meanwhile Ryan and Esposito each hope to supplement their meager family budgets via the NYPD sergeant detective exam. Written by KGF Vissers

Did You Know?


When Castle learns P.J. Moffet has been murdered, he mentions that Moffet only published one book in his lifetime. This could be a reference to author Harper Lee, who, for the majority of her life, also only published one book, To Kill a Mockingbird (1962). A few months before her death, she published "Go Set a Watchman"; while it was initially promoted as a sequel, it has since been accepted as a first draft of "Mockingbird". See more »


At the opening Beckett is making a cup of coffee. She is shown frothing milk than pouring it into a cup. She tastes the coffee, it appears to be bad, and she pours black coffee down the drain. See more »


Richard Castle: I couldn't help but overhear about your financial concerns. Maybe you and I could work together.
Kevin Ryan: How?
Richard Castle: Well, do a little, uh... moonlighting for me. Just keep me in the loop as to what's going on at the 12th.
Kevin Ryan: You want me to be a rat for you? Hell no.
Richard Castle: I would pay you five hundred a week.
Kevin Ryan: I'll do it.

the further the worse
13 October 2015 | by (Moscow) – See all my reviews

It's awful. The writers think, that the happiness of main characters is tedious for us, they want us to worry. Morons. All the charm of the show is in that happiness, and trust, and joint work - there is enough for the detective serial. Now it's a bloody soap opera. A bad one. A veeeery bad one. The wife leaves her husband because of work. Stupidity. "I love you but I need time". For what?! More stupidity. Having destroyed the family, the wife is not very concern and smiles all the time. More and more stupidity. The husband wants his wife that loves him to fall in love with him again. Oh. my. God. The most idiotic twist ever. And where the detective? Forgotten. Stories are far-fetched, predictable and banal. Jokes are boring. I'm crying.
