'They watch me all the time. In and out of the classroom, their eyes are always following me . . .'

Quiet, gentle, young Faustina Crayle is dismissed from her teaching position at Brereton School for Girls after just a few weeks. She is given no explanation, but it's clear certain staff and pupils fear her.

Her friend and fellow teacher Gisela contacts psychologist and sleuth Dr Basil Willing who offers to investigate these outlandish claims. But this only confirms two damning facts - first, that this happened at a previous school and, second, people believe there are two sides to enigmatic Faustina.

When a body is found at the school and Faustina is implicated in the death, it is clear that darkness swirls around this young woman. But is she the perpetrator or victim?
