Promise Not to Tell

Jennifer McMahon, . . Harper, $13.95 (250pp) ISBN 978-0-06-114331-1

Part mystery-thriller and part ghost story, McMahon's well-paced debut alternates smoothly between past and present. In the fall of 2002, 41-year-old Kate Cypher, a divorced Seattle school nurse, returns to New Hope, the decaying Vermont hippie commune where she grew up, to visit her elderly mother, Jean, who's suffering from Alzheimer's. Kate has avoided New Hope since the grizzly, unsolved murder of her fifth-grade friend, Del Griswold, 31 years earlier. Kate fears she betrayed Del, a free-spirited farm girl. Did her betrayal cause Del's death? Who killed Del? Another local girl is murdered in a similar manner at the time of Kate's return. Could the killer be loose again? Meanwhile, Jean appears to be possessed with Del's spirit and may have the answers to these questions. As Kate investigates, she learns stunning truths about many events and people from her youth. McMahon does a particularly good job of portraying the cruelty of school children. (Apr.)
