Katherine Knight, Sarah Makin, Caroline Grills, Catherine Birnie, Helen Moore, and Rachel Pfitzner are among the most notorious female killers in Australian history. But what compels a woman to take a life, whether it’s someone close to her or, more rarely, a stranger?

Dr Xanthe Weston, a criminal psychologist, has long been driven by this very question. Drawing on years of research into cases like these, she joins us today to explore what she’s discovered - why women’s motives for killing often differ from men’s, and whether some perpetrators are inherently predisposed to violence, or shaped by circumstance.
