The fourth book in the Reacher series lacks the action, pacing and plausibilty of the earlier novels. A careful reader sees the ending coming long before one should. Like Reacher, the book feels burdened by house, girlfriend and responsibility. Put him back on the road, before he stops being as entertaining as he was in the earlier books.
