Tick, Tick, Tick… No, we’re not talking about that pulse-pounding “Tick, Tick, Tick…” episode from Season 2. This tick tock is on Beckett’s clock. It’s counting down to when she and Castle can escape the city for a romantic weekend in the Hamptons. Wonder if they'll be staying near Grayson Manor. Anyway, five on Friday finally rolls around with no pesky murders to spoil the plans. Castle’s story is that he’s off to write. Ryan and Esposito know that Beckett is also going away with her new boyfriend. They make it their mission to find out just who this mystery man is.
Beckett is in awe of Castle’s castle at the beach. She wonders how many other women he’s whisked away to this oasis. There have been a few for sure, but none of those other ladies were her. This brings a smile to Beckett’s face. Castle is also smiling once he realizes Beckett forgot her bathing suit. Unfortunately, someone else decides to take a dip in the pool as a man covered in blood stumbles in from the beach. SPLASH! The guy’s dead in the water. Looks like Castle and Beckett are in for a killer weekend!
The victim is a weekender named Randal Franklin who was at a party up the beach. Local Police Chief John Brady believes his deputy has caught the killer when he wrangles up a drugged out dude who was in possession of the dead man’s wallet. Castle doesn’t think it’s that simple since there’s no blood splatter on the alleged shooter. Beckett knows they won’t be able to get on with their weekend until he gets some answers.
Castle learns that Franklin was arguing on the beach with a woman in a white dress. The guy was also part of an insider trading scandal. Castle asks for help from Ryan and Esposito, who are busy pestering Lanie about Beckett’s boyfriend. The boys question Franklin’s wife who says her husband was likely arguing with Natalia Roosevelt, the girlfriend he was ordered to dump. Too bad Natalia is pals with Chief Brady, who arrests Castle and Beckett for interfering in his murder investigation.
