Most serial killers are male. But the women are often overlooked, and they can cause quite a bit of distruction before getting caught (if they ever do). Primarily poisoners, female serial killers are poorly studied or understood, which makes this book such an interesting read. But this is more of a true-crime book, not an actual examination of the mind of a serial killer or analysis of the history, psyche, and statistics surrounding women who kill. On the plus side, this book doesn't make the common mistake of calling spree killers serial killers. ( )
