The first child disappeared sixteen years ago... Sarah Finch's older brother went out to play - and disappeared. No one else saw him - neither alive nor dead... The second child disappeared recently... Twelve-year-old Jenny Shepard did not return home. And Sarah Finch - her teacher - discovered the girl's body in the forest. Two disappearances. One witness. One criminal? There is no doubt that Jenny was the victim of a brutal crime. But Sarah is the only one who thinks: what if her student's killer is the same person who was once connected with the disappearance of her brother? Sarah begins her own investigation. The police laugh at her suspicions. And someone is watching her and is preparing to stop her as soon as she gets too close to the truth.
