Brady learns that Beckett is a top homicide cop, so he asks for help on the case. The guy’s in over his head after working in a town where he’s never even pulled his gun. Beckett gets Natalia to admit that she thought Franklin was using her to get her council vote for a helicopter pad. She says the victim ran off after getting a text sent from a burner phone. In other news, Castle believes “Caskett” is a cool new “couple nickname” for him and Beckett. Sorry, Ricky boy, we’ve been using that one for awhile now.

The victim’s lungs were full of salt water which indicates he was shot offshore. The drugged out dude remembers seeing a boat owned by Aaron Lerner the night of the murder. He just happens to be one of the people Franklin sent to prison in his insider trading case. Castle trips over a sloppy rope tie job as they confront Lerner at the dock. The guy claims he and Franklin made peace even though there’s blood splatter on his boat. Lerner believes the real killer may be Franklin’s neighbor, who happens to head a New York crime family.

Castle invites mob man Vinnie “The Scar” Cardono (great name) over to his place for a bite. That was a mistake. He totally ticks off the crime lord who didn’t like the fact that Franklin used to buzz his helicopter over his place. But Vinnie the Scar is no killer, at least not in this instance. Back in the city, Esposito and Ryan learn that Franklin was buying buildings to use as meth labs. Beckett and Castle realize that their victim was using his helicopter to transfer drugs to the beach.
