In the search for the missing West Point graduate, Reacher found out something.
Actually, I have guessed that much why no one see the woman living in such a low density population.
Her twin sister is beautiful. And beautiful woman like to be seen.

And the ring indicated that either she was a victim of a crime, or she had given up in exchange something that is more important to her at the time.
Sad really. Not a lot of action. More like a detective story than usual.
