Home is Where the Heart Stops

When a member of New York's high society is found murdered and stuffed into a small wall safe, the Department is put under pressure to get to the bottom of the story. But to get the answers to the string of robbery/murders, places must change; rather than Castle visiting New York's dark alleys, Beckett must follow him into the world of glitz, glamor, and, ultimately, murder, after they discover that the robberies are only connected by the victims having attended a specific charity event.
