Jack Reacher follows his lizard-brain instincts on a seemingly uneventful night in Nashville, where a recently fired man nurses an increasingly violent grudge.

"It is close to midnight on a Saturday night when Jack Reacher gets off a bus at the Greyhound station in Nashville. Reacher is in no hurry. He has no appointments to keep. No people to see. No scores to settle. Not yet anyway. But in the early morning hours, under particular circumstances, a familiar thought will be snaking through his sharp, instinctual lizard brain: A voice in his head telling him to walk away. Of course, this wouldn't be the first time he listened to his gut instead. Meanwhile, seventy-five miles south and west of Music City is a sleepy little town where a recently-fired guy nurses a grudge that will fester into fury--and a desire for payback. But who is watching him, standing guard over a long-buried secret, ready to strike before it can be revealed? If you don't have a sense of the danger you're in, then it's best to have Reacher"--

As always, Reacher has no particular place to go, and all the time in the world to get there. One morning he ends up in a town near Pleasantville, Tennessee. But there's nothing pleasant about the place. In broad daylight, Reacher spots a hapless soul walking into an ambush. 'It was four against one,' so Reacher intervenes, with his own trademark brand of conflict resolution. The man he saves is Rusty Rutherford, an unassuming IT manager, recently fired after a cyberattack locked up the town's data, records, information and secrets. Rutherford wants to stay put, look innocent, and clear his name. Reacher is intrigued. There's more to the story. The bad guys who jumped Rutherford are part of something serious and deadly, involving a conspiracy, a cover-up, and murder, all centered on a mousy little guy in a coffee-stained shirt who has no idea what he's up against. Rule one: if you don't know the trouble you're in, keep Reacher by your side.
