The irreverent detective is back, and this time she's on vacation. God help us all...
St. Paul, Minnesota Homicide Detective, Catherine O'Brien, and her loving husband Gavin, are vacationing on one of Minnesota's 10,000 lakes. When a local is murdered, Catherine is tapped to help the small town Sheriff until the Bureau of Criminal Apprehension arrives to take over the investigation. Catherine is surprised when her partner Louise and Diggs, the forensic pathologist, whose crush on Louise is only dwarfed by his own genius, show up to assist instead of the BCA. Before long, Catherine and Louise discover this sleepy little town has a dark side hidden beneath its placid lake charms. Somewhere in the tangle of cheating and deception is a motive for murder.
