Tripwire (Jack Reacher )

In Tripwire, Reacher is settling into lazy Key West when his life is interrupted by a stranger who comes looking for him. When the stranger turns up beaten to death in the Old Town cemetery - fingertips removed - Reacher knows whomever the man was working for is not a friend. Reacher follows the trail to New York, where he confronts the people who dispatched the dead man: an elderly couple still mourning an all-American son lost in Vietnam; an alluring and intelligent woman from Reacher's own haunted past; and at the center of the web, an opponent more vicious than any he's ever faced.
