When Esmé Foster left the Boston suburbs to become a professional ballerina, the future shimmered with promise. Eleven years later, her career has been derailed by an injury, and she knows it’s time to come back to Graybridge to help her brother care for their ailing father. But her return coincides with an unthinkable crime. Kara Cunningham, one of Esmé’s high school friends, is found dead in the woods behind the Fosters’ house. Esmé is shocked and grieving, but also uneasy. In her dreams, she still sees the man who showed up at the scene of the car accident that killed her mother --- and told Esmé he was going to kill her too. Family and friends insisted the figure was a product of Esmé’s imagination, that she was concussed after the crash. But she and Kara looked alike. Could Kara’s murder have been a case of mistaken identity?
