Surrounded by dense, dark wooland, The Hermitage is an exclusive girls school. One balmy summer's night Sukie Melville leaves her room and vanishes into the woods. The following day her body is pulled from the hungry water of the Menai Strait. Superintendent, Michael McKenna and his team move in to investigate the death. The school's charismatic headmistress insists it was suicide, but McKenna isn't so sure. When McKenna scratches the glossy surface he uncovers a dark and dangerous ethos underpinning the school. Nothing in that hotbed of passionate, brooding resentments is what is seems, and no one can be trusted.
