Home Is Where the Heart Stops

Beckett must enter into Castle's mileau of celebrity and money, portraying his date at a formal social event in the hopes finding those behind a rash of high society home invasions and thefts, the latest of which ended in a brutal murder. Castle finds his own problems when he seeks the assistance of a presumably retired, but dangerous master thief he used as a character model, who at one time made threats to Castle's life. Does he still bear a grudge? Is it him behind the robberies?
