Summary

Host Kate Lister and Professor Joanna Birk explore the 1909 case of Martha Rendell, the last woman hanged in Western Australia for murdering three stepchildren with acid. They analyze how the "evil stepmother" trope, fears of baby farming, and gender biases shaped the sensational trial and public outrage. The discussion also covers how interpretations of Rendell’s motives shifted from religious degeneracy to sexual sadism over time.
