From Beverly Allitt, the attention-seeking nurse who preyed on the children in her care, to the infamous Dr. Harold Shipman, who was responsible for the deaths of at least 215 of his patients, Carol Anne Davis delves into the tragic stories behind these healers who became murderers.

What would drive a child prodigy turned brilliant doctor to murder his wife? Why would a Scottish nurse resort to murdering the elderly patients under his care? What motive could a promising Harvard medical student have for attacking her friend and roommate?

At their best they cure disease, look after the sick, and are sworn to ‘do no harm’. So what leads a small minority of healthcare workers to a life of violent crime?

Including in-depth analyses and exclusive interviews with experts in the fields of mental health and criminology, this makes for fascinating, and chilling, reading.

CAROL ANNE DAVIS was born in Dundee, moved to Edinburgh in her twenties and now lives in the south of England. She left school at fifteen and was everything from an artist's model to an editorial assistant before going to university. Her MA degree included criminology and was followed by a postgraduate diploma in Adult and Community Education.
