The team continues the search, and the next victim is Agent Lamarr's stepsister. Local policemen are then put on surveillance of the remaining women on the list. Eventually Reacher and Harper catch the killer. It is none other than FBI Agent Lamarr. She is in the process of killing her fifth victim when Jack intervenes. Reacher and Harper come to the conclusion that Lamarr was utilising her hypnotising techniques to make the victims unwittingly suffocate themselves by swallowing their own tongues. Her motives were a family inheritance and a sociopathic bitterness to her stepsister; the other murders were carried out to muddy the investigative waters. The FBI is unhappy that Reacher has killed one of their agents, murderess or not, but an accord is eventually reached. Jack then meets up with Jodie, and she reveals she is leaving for London in a month's time. Reacher knows he will not want to go with her, since he misses his wandering ways, and the two agree to spend one last month together.
