Beckett hasn't heard from Castle since he left for the Hamptons months ago to finish writing his second Nikki Heat novel, "Naked Heat." The most Beckett, Ryan and Esposito have seen of Castle is a bookstore standee of him advertising an upcoming book signing. So when Beckett and her team burst into a shadowy apartment on the trail of a murderer, the last thing they expect to see is the real-life Castle standing over a dead woman's body holding a gun. As Castle protests his innocence, Beckett has no choice but to arrest him on suspicion of murder. Written by ABC Publicity

A good start to a terrific Third Season
30 July 2013 | by xboy614See all my reviews

A deadly affair is a solid and good start to the third season of Castle, when a Michael Connelly type mystery writer gets to solve crimes with a tough, but savvy female Detective, Beckett. This episodes evokes the fun of the First season with the witty one-liners seen in the second season. Friendship between Beckett and Castle is rebuilt in a cool way and it is intertwined with a "not your usual" crime involving a Vending machine operator, a teacher and a Statue-maker. This episode almost signals the the great ones to come and my only criticism to it is that it is not forgetful, or predictable but there are just so many other episodes which either have better plots or are funnier.
