Reacher finds himself in trouble (as usual) from Chapter One on. He (seemingly) happens upon a kidnapping attempt against a kid headed home from college. The rescue involves him with the kid's father, a rug merchant with a remote mansion on the previously-mentioned rocky coast. But all is not as it seems: the rug merchant seems to have a different, more lucrative, and much less legal, sideline. There is an impressive array of evil henchmen hanging around, but it's unclear who their actual boss is. And (as it turns out) Reacher himself is there under false pretenses, looking to settle a grim score with a criminal mastermind he thought he had dealt with a decade previous.
As always: edge-of-your-seat suspense, gritty action, well-drawn characters, masterful detective work, and pretty good writing.
Just a quibble, with this and a lot of other books. A lot of stuff happens that depends on the reader understanding both the geography of the area and the physical layout of various scenes. Since the publisher is raking in millions, would it kill them to include some maps and floor plans?
