As always, it is Reacher's all-consuming obsession with revenge, or at least with his personal interpretation of doling out justice, which pushes him far beyond the normal boundaries of physical endurance and acceptable risk. And it is revealed that Zachary was forced into working for Quinn and his family was tormented by bodyguards appointed by Quinn. It's ten years later and Quinn somehow just happens to be Zachary Beck's boss in a supremely lucrative, international gun-running enterprise. Reacher had originally presumed Quinn to be dead after their last little encounter but found that assumption to be incorrect after running into Quinn in public. Reacher refuses to step back as his primary motivation in getting involved at all in this off-the-books operation is to have another go at Francis Xavier Quinn, a former Military Intelligence agent who, ten years before, had brutally mutilated and murdered a female military colleague of Reacher's. The DEA, on finding that they were mistaken about the nature of the business Zachary was involved in, tries to pull Reacher out. The house maid, too, turns out to be a federal agent trying to find evidence of arms smuggling against Zachary.

During this time he figures out that he was not the only undercover agent appointed to keep track of Zachary Beck. While working undercover he regrettably has to eliminate a few of Beck's minions to prevent them from exposing him. Reacher gains access to Beck and gradually gains his confidence by working as a hired gun/bodyguard.

A frightened Richard places his trust in Reacher and asks him to take him back home.

They stage a kidnap effort on Zachary's son, Richard Beck. Jack Reacher is working unofficially with the DEA to bring down a boy's father, Zachary Beck, who is suspected of smuggling drugs under the pretext of trading in oriental carpets.
