Katherine Knight is 'top dog' in Sydney's tough Silverwater Women's Correctional Centre

Katherine Knight is now at tough Aussie prison Silverwater - right, the crime scene after she butchered her boyfriend

One of my highlights of 2021 was bingeing Aussie prison drama Wentworth so finding out that Katherine Knight is 'top dog' of her prison really sent my imagination in to overdrive.

I won't lie, Joan Ferguson has become one of my all time life heroines, to the point I want to take up fencing and wear leather gloves. But is she as fearsome a cellmate as the 'cannibal killer' Kathy K?
