Minneapolis Homicide Sergeant Harding Knox becomes embroiled in a murder investigation at the grave of a state court judge. Hours later, a gruesome double homicide of two Native Americans is reported in a wooded park near the Mississippi River. Both events lead Knox from an obscure Jewish cemetery in Minneapolis to Mackinac Island, Michigan, a confrontation with a dubious private detective, and to a woman of mystery. All the while, Knox continues to wrestle with the loss of his wife, and a rediscovered relationship with another woman. In the background, intrigue threatens the political ambitions of the city's mayor, tied to the fate of Knox's Nicollet Island home. Although confronted with his own conflicts, Knox is compelled to find an elusive connection, and justice for three murder victims. A person of interest and his two henchmen are identified. Yet, Knox becomes entangled in the priorities of federal agents that lead him down an unpredictable, and dangerous path into the Black Hills of South Dakota. However-some things are not always as they seem. If you enjoy the stories of Michael Connelly, Nelson DeMille or David Baldacci, take a ride with Harding Knox.
