Tripwire (Jack Reacher #3)

Jack Reacher, ex-military policeman relaxed in Key West until Costello turned up dead. The amiable PI was hired in New York by the daughter of Reacher's mentor and former commanding officer, General Garber. Garber's investigation into a Vietnam MIA sets Reacher on collision with hand-less "Hook" Hobie, hours away from his biggest score.
