Book excerpt: It was the safest state in America, where a single murder in a year was the usual. People there descended from hearty settlers who had withstood a challenging life by cooperating. When a growing young town with recently paved streets was struck by annual murders for three consecutive years, something had changed. Each crime was more violent and heinous than its predecessor, beginning when one of the towns favorites, a personable high school cheerleader, was murdered in her familys home in a sex-related attack. Within months came the bloody bludgeoning to death of a young mother in her own home. As one homicide was prosecuted and investigation moved forward on the second, a young mans body was found bisected, with the halves floating in bags in a river.
