They call her 'the gangbuster'.

The police force can be a tough place for a woman, but Detective Superintendent Deborah Wallace rose to the top with grace, humour and an iconic sense of style. In her incredible 36-year career with NSW Police, Wallace took on murderers and drug suppliers, and dismantled the state's most nefarious gangs.

Tenacious, perceptive and sharp, Wallace commanded a range of police crime squads, bringing order to the wild west of 1990s Cabramatta and busting criminal bikie gangs with Strike Force Raptor, until her retirement in late 2019. Her inner strength and empathy meant that she was a constant go-to for some of the state's toughest cases, and her poise and compassion earned her a special place in the lives and hearts of her colleagues - and the grudging respect of her criminal foes.

In Wallace's official biography, veteran crime writer Mark Morri brings to life the jaw-dropping true story of a police trailblazer and woman of force.
