Bad Luck and Trouble by Lee Child

Jack Reacher is back! In Bad Luck and Trouble, Reacher receives an SOS from an army buddy. She tells him that a colleague from their old MP unit, hand-picked and run by Reacher, was murdered--dropped 3000 feet from a plane. Being a steadfastly loyal guy, Reacher agrees to regroup the special investigators, disbanded ten years ago, to find out what happened to their friend and to avenge his death. Again, Lee Child creates a book with non-stop action and ripe with intrigue. Unputdownable.
