This is a nice easy read. Jesse Stone faces two challenges while at the same time trying to sort out his confusing love-life. The first challenge has to do with a Junior High School Principal, who --under the pretext of proper attire and behavior for her students-- examines their underwear in the locker room. Jesse wants to punish her, but her high-powered attorney husband prevents him. The second and more relevant challenge has to do with a tormented voyeur, dubbed the Nighthawk. This perpetrator escalates from peering through Windows to forcing his victims to undress at gunpoint, then photographing them while naked. Jesse sets a trap and catches the Nighthawk, killing him in a subsequent shootout. Sunny Randall appears, along with Susan Silverman –Spenser's sweetheart— as her psychiatrist. I liked the book.
