Knowledge as power
The prologue's unnamed voice argues that knowing the lottery numbers or the market's future is real, hard power, and that killing is just another field where knowledge wins. The whole plot proves it: the killer's advantage is not strength but specialized knowledge of hypnosis, of the victim profile, of how investigators think. Reacher wins the same way, by knowing things others don't, from the honey trap's purpose to the single murder buried in the pattern. The book's point: in this story, the person who understands the most controls who lives.
