NATIONAL BESTSELLER • The gripping new Jack Reacher thriller from bestselling authors Lee Child and Andrew Child
 
A string of mysterious deaths. A long-classified mission. A young MP with nothing to lose.

1992. All across the United States respectable, upstanding citizens are showing up dead. These deaths could be accidents, and they don’t appear to be connected—until a fatal fall from a high-floor window attracts some unexpected attention.
 
That attention comes from the secretary of defense. All of a sudden he wants an interagency task force to investigate. And he wants Jack Reacher as the army’s representative. If Reacher gets a result, great. If not, he’s a convenient fall guy.
 
But office politics isn’t Reacher’s thing. Three questions quickly emerge: Who’s with him, who’s against him, and will the justice he dispenses be the official kind . . . or his own kind?
