risks involving the media by releasing a photo of the victim, hoping to find someone who knew her. Louise's gamble pays off: an older woman phones to say that she recognizes the woman as Lisemette, a child she once cared for in the state mental institution many years ago. Lisemette, like the other children in the institution, was abandoned by her family and branded a "forgotten girl." But Louise soon discovers something more disturbing: Lisemette had a twin, and both girls were issued death certificates more than thirty years ago. Aided by her friend journalist Camilla Lind, Louise finds that the investigation takes a surprising and unsettling turn when it brings her closer to her childhood home. And as she uncovers more crimes that were committed - and hidden - in the forest, she is forced to confront a terrible link to her own past that has been carefully concealed.
