Near the grounds of an abandoned mental hospital, a buried chamber is discovered. Inside are six bodies, one of which may be that of a girl who has been missing for two decades--the best friend of a woman, Annabelle, who has spent her childhood moving from city to city, from identity to identity, hiding from someone or something totally unknown to her. She's been safe for several years now, but a single act of bravery plunges her right back into a life of fear. This is a rich, complex tale that juggles a handful of mysteries at once. Who is the killer, and could it be someone connected with a notorious child murderer? Who or what was Annabelle's family running from? How did her father, a mathematician, know how to set up foolproof new identities? And why does an old sketch of a murder suspect look unsettlingly like Annabelle's father? Head and shoulders above anything else Gardner's written, this riveting novel represents the author at the height of her powers.
