In their young romance, Castle and Becket decide to take a weekend at his home in the Hamptons, and an impressive place it is. Of course, a murder victim staggers up his yard from the beach and falls into his pool.
Awkward. They're trying to keep their relationship secret, and this is an event where secrecy is far from guaranteed. In fact, Castle doesn't like the local police chief's choice of culprit, so he and Becket get involved, trying to balance investigating a murder with keep their secret.
Castle's clue to uncover the real murderer is cute, and while the clues don't tell you who the murderer is, they DO keep telling you who it isn't.
Lots of scenes involving keeping their secret and their relationship with the local police chief are highly amusing. A good watch.
