While this series has lost its spark since Beckett and Castle became a couple, the first of this week’s double episodes is an entertaining whodunit.
The case: the murder of an upcoming DJ at a pop star’s album release party. There are so many potential suspects, including a troubled teen who Esposito tries to put on the right path, that it makes it near impossible to guess who the killer is – all part of the fun.
The second episode sees Beckett and Castle on the hunt for a fairytale killer who is murdering women dressed as Disney characters in story-like circumstances.
