The story begins with a revisit to the boutique town of Round Lake, South Dakota, by Brad Davis, a now retired FBI profiler who once grew up in the town during the period when trains actually made a stop to offload the day's mail. Today the town's claim to notoriety no longer is the German sausage produced by its aging butcher but rather the people within the community still trying to determine what had happened to the four teenagers who had made the annual trip to their lake of the same name. Despite having the most advanced criminal technology at its disposal, the city soon discovered that every trace of the girls had just flat-out disappeared with few people still believing that they had accidently drowned. Davis soon involves himself in a reinvestigation of the case with the help of a female private investigator from the small town of Wing, South Dakota. Together they follower the usual twists and turns of a good mystery while at the same time finding the love that had escaped them both. One of the best and most enthralling novels Dempsey has written.
