A cold-blooded kidnapper has been playing a twisted game with a terrified Minnesota town. Now a respected member of the community stands accused of a horrific act of evil. But when a second boy disappears, a frightened public demands to know: Have the police caught the wrong man? Is the nightmare continuing—or just beginning? Prosecutor Ellen North believes she’s building a case against a guilty man—and that he has an accomplice in the shadows.
