Female serial killers are anomalous enough but this one was particularly crafty. Literally. She made her victims into soap and tea cakes.
Describing her final victim, "She ended up in the pot, like the other two... her flesh was fat and white, when it had melted I added a bottle of cologne, and after a long time on the boil I was able to make some most acceptable creamy soap. I gave bars to neighbours and acquaintances. The cakes, too, were better: that woman was really sweet."
