A dying woman is suffocated in her hospital bed. Her last visitor, Madeleine Reed, is accused of the crime. There are no witnesses. Madeleine cannot recall committing the murder and has no motive. Claiming to be pursued by the Furies, punitive figures from Greek mythology, she is found guilty of manslaughter on grounds of diminished responsibility. After her release from a secure hospital she is drawn back to the Cornish coastal village where she lived before the murder and where her mother had died years before in mysterious circumstances.


Slowly, her memories begin to return. She knows that she must finally confront the hideous Furies who alone can bring the truth to light. But can she bear to uncover the horrific, distant memories she has repressed for so long?
