1906: Being a woman is dangerous, being different is deadly. Maud Lovell has been at Angelton Lunatic Asylum for five years. She is not sure how she came to be there and knows nothing beyond its four walls. She is hysterical, distressed, untrustworthy. Badly unstable and prone to violence. Or so she has been told. When a new doctor arrives, keen to experiment with the revolutionary practice of medical hypnosis, Maud's lack of history makes her the perfect case study. But as Doctor Dimmond delves deeper into the past, it becomes clear that confinement and high doses are there to keep her silent. When Maud finally remembers what has been done to her, and by whom, her mind turns to her past and to revenge.
