 Dalziel and Pascoe investigate the murder of Nancy D Amato whose body is found by a squad of soldiers on training. She was an American tourist who was traveling alone and may have been drugged before she was beaten to death. It s determined that Nancy was seen at a pub with two young soldiers from the nearby military training base, one of whom subsequently commits suicide. Nancy s husband Gus, a Boston homicide detective, arrives and isn t pleased with the way the investigation is being handled. Andy is quite pleased as he gets the opportunity to work with DS Jenny Ettrick, an old flame. However, she was once married to one of the witnesses in the case and may be hiding a conflict of interest. When the second soldier is killed, suspicion falls on his brutish sergeant but the detectives must return to basics when they realize they made a serious error from the outset.
