“The Baby Farmer.” “The Giggling Granny.” “The Soap-Maker of Correggio.” “The Granny Ripper.” These are the nicknames of Amelia Dyer, Nanny Doss, Leonarda Cianciulli, and Tamara Samsonova. Look at pictures of them and you might see smiling and gentle-looking elderly women. But there was nothing gentle about these women. All of them were brutal serial killers. They killed relatives, husbands…children. Some they ate, some they turned into bars of soap and sold. It’s as disturbing as it gets under the Black Umbrella. Come on in, the murder is fine.
