Why does a young woman lure teenagers into her car then participate in their horrific rape and torture? What makes a nurse lethally inject the healthy babies in her care? Women, statistically, aren`t a violent breed ... but the female of the species can be just as deadly as the male.

From the mass poisoner to the sexual sadist, from profit killings to crimes committed just for twisted thrills, Carol Anne Davis sets out to explore the dark and disturbing world of the female serial killer. In depth analysis of individual cases, including new information from the minister who heard Myra Hindley`s confession, provides an invaluable insight into the psychology behind these atrocities.
