Salem's chief of police, John Rafferty, now married to gifted lace reader Towner Whitney, investigates a 25-year-old triple homicide dubbed "The Goddess Murders," in which three young women, all descended from accused Salem witches, were slashed one Halloween night. Aided by Callie Cahill, the daughter of one of the victims who has returned to town, Rafferty begins to uncover a dark chapter in Salem's past.
