For some, home is where the heart stops. Literally. After an accelerating — and increasingly violent — series of home invasions in high-end neighborhoods, Beckett and Castle work to unmask a murderous jewel thief before he (or she) strikes again.

For his part, Castle seeks the counsel of a dangerous ex-jewel thief who had once threatened to kill him.
