Witnessing a woman pushed to her death in front of a bus, Jack Reacher, following the killer on foot, is unaware that this is part of a secret conspiracy with many moving parts with no room for error and any threats will be permanently removed, including Reacher. In Gerrardsville, Colorado, two witnesses to the same tragedy give two different accounts: One sees a woman throw herself in front of a bus in what authorities will call a suicide. The other witness is Jack Reacher. And he sees what actually happened: A man in a gray hoodie and jeans, moving like a shadow, pushed the victim to her death before grabbing the dead woman's purse and strolling away. Reacher follows the killer on foot, not knowing that he is part of something much bigger: a conspiracy with many moving parts, with powerful people on the take, all involved in an undertaking that leaves no room for error. If any step is compromised, the threat will have to be quickly and quietly and permanently removed. Because when the threat is Reacher, there is No Plan B. -- adapted from back cover
