Book excerpt: Murder has always fascinated us, and when women are the masterminds, the intrigue grows exponentially. Not only are female murderers much rarer than male killers, but their crimes usually also involve a more sophisticated type of plotting. In Blood on her hands, award-winning journalist Tanya Farber investigates the lives, minds and motivations of some of South Africa's most notorious female murderers, from the poisonous nurse Daisy de Melker, to the privileged but deeply disturbed Najwa Petersen, to the mysterious Joey Harhoff who died before revealing where the bodies of her victims (including her own niece) were. Farber sets each case against the backdrop of the different eras and regions of 20th and early 21st century South Africa the women operated in. Her writing style is lighter than the subject matter might suggest and Blood on Her Hands will keep you reading until late at night – probably with your light on. The women featured also include: Dina Rodrigues, Phoenix Racing Cloud Theron, Marlene Lehnberg, Chane van Heerden and Celiwe Mbokazi.
