Forensic psychiatrist Dani Harris and her partner Tommy Gunderson continue to investigate the ritual murder of Julie Leonard, last seen alive at a party attended by students from St. Adrian's Academy, an exclusive boys' school in New York's Westchester County. Another death--of an Alzheimer's patient and pious historian, Abbie Gardener, somehow crushed by sucking asphyxiation one night in her room at the school--complicates their inquiry.
