After almost a century, Daisy de Melker's name still comes up when one mentions women serial killers.
Daisy, like many other womenkillers, had a "caregiving" role — she trained as a nurse and knew how the body worked.
In 1923, when she was living in Johannesburg, she prepared Epsom salts for her first husband, William Cowle, adding a poisonous substance.
This became clear only after a second doctor had seen him — by which time Cowle was foaming at the mouth, turning blue, and screaming in pain if anyone touched him.
The doctor suspected strychnine poisoning but the death certificate — signed by another doctor — blamed chronic nephritis.
Daisy inherited £1,795.
Four years later, after she had married again, her husband Robert Sproat became violently ill after ingesting something she had prepared. His symptoms resembled Cowle's — but he survived.Ian-Malcolm Rijsdijk, senior lecturer in film studies at UCT, says some of the most memorable female psychos from film are defined by their cold and seemingly rational calculations, and others by their wild irrationality.
