Does true evil ever die? The discoveries in isolated North Dakota of an amputated hand of a young woman and, dangling in a tree nearby, the battered corpse of a man are the catalyst to begin an investigation that leads to the inescapable conclusion that generations of serial killers have been active in the northern plains for over a century. These killers share a ghoulish methodology, the surgical whittling away of their live victims. Undersheriff Joyce Smith, a Hunkpapa Sioux Indian, heads a team of investigators, including police, a medical examiner, a private detective, an historic crime expert, a nurse, an archaeologist, and a newspaperwoman in their search for the killer. Dubbed Jack-the-Snipper by the press, the killer toys with and lashes out at the team of investigators. Signing his letters as "You Know Who," the killer presents Undersheriff Smith with a challenge to find him by a certain time or his latest captives, including someone important to Undersheriff Smith, will die under his scalpel. Evidence trails lead in many directions, including an ex-CIA "Spook," a satanic cult, and, most perplexing of all, Jack-the-Ripper himself. Join Undersheriff Smith and her team in this page-turning thriller as they take a desperate journey into the heart of evil.
