Yes, this book contains a mighty evil bunch of nasty, rotten women! I had heard of 10 of the 15 women profiled here (Lizzie Borden, Audrey Marie Hilley, Valeria Messalina, Agrippina the Younger, Catherine the Great, Elena Ceaucescu, Mary Ann Cotton, Rose West, Aileen Carol Wuornos, and Myra Hindley); five were new to me (Tz'u-Hsi, Queen Ranavalona I, Marie Noe, Grace Marks, and Karla Homolka). The author emphasizes that many men have committed acts as bad or worse than these women did. What makes these women's crimes particularly horrible is that they were committed by women, who are supposed to be nurturers, of the "gentler sex."
I can't decide which one was the worst. Certainly Valeria Messalina, Agrippina the Younger, Catherine the Great, Elena Ceaucescu, Tz'u-Hsi, and Queen Ranavalona I were responsible for the deaths of more people than the others in this book because they wielded political power. I knew nothing about the history of the island of Madagascar until I read about Queen Ranavalona I. I find it amazing that the missionaries kept coming there even though the queen kept having them killed. Elena Ceaucescu's arrogance, pride, and self-centeredness were unbelievable. Poor Emperor Claudius had the bad luck to be married to both Valeria Messalina and Agrippina the Younger. I guess he was a really bad judge of women!
The one woman who, it could be argued, may not belong in this book is Lizzie Borden. Not everyone is convinced that she murdered her parents. Some theorize that her sister Emma actually did it, or the cousin who had spent the night. Personally, I think Lizzie did it.
I like how Klein writes. She summarizes each case well. I learned something even about those women whom I had already read about. I recommend this book to anyone interested in true crime, especially as it pertains to women.
