The Secret by Lee Child & Andrew Child

1992. Two strangers bring a hospital patient a list of names. They ask him for one more, but it's a question the patient can't answer. Minutes later he is dispatched through the 12th floor window.

His death generates some unexpected attention. That attention comes from the Secretary of Defence, who brings in an inter-agency task force to investigate. Jack Reacher, recently demoted from Major to Captain, is assigned as the Army's representative.

Reacher may be an exceptional soldier, but sweeping other people's secrets under the carpet isn't part of his skill set. As he races to find the killer, he must navigate around the ulterior motives of his new 'partners'. And all while moving into the sight line of some of the most dangerous people he has ever encountered.

His mission is to uncover the truth. Fast. The question is: will Reacher bring the bad guys to justice the official way . . . or his way?
