The Schoolhouse - Sophie Ward

Isobel lives an isolated life in North London, where she works at a nearby library. She feels safe, so long as she keeps to her routines and doesn't let her thoughts stray too far into the past. But a newspaper photograph of a missing local schoolgirl and a letter from her old teacher send her spiralling and bring back the trauma of what happened years ago, when she was a pupil at The Schoolhouse.
