Watch online episod 22 – "To Love and Die in L.A."
Mike Royce, Becket’s former police mentor, who lost his bounty-hunter license when she arrested him, is murdered while visiting New York, possibly by a fellow passenger from L.A. The captain takes her off the case but she uses extant leave. Castle comes along, having to visit his book’s movie set anyway. Informally backed up by Ryan and Esposito, hey soon find Royce must have been after the manufacturer of the dissolving type of bullet he was killed with. The trail of arms-dealings and new crimes leads back to New York, fortunately as LAPD detective Kyle Seeger, who follows, wants them out as much as Montgomery ordered Becket back.
