In March 2009, Joseph Fritzl was sentenced to life in jail for the systematic imprisonment, torture and rape of his daughter Elisabeth over 24 years, fathering seven children. The case shocked the world. But just a month before, the story of Australia’s own house of horrors was emerging in a Victorian country town. Under a blanket of suppression orders, a man in his late sixties was quietly arrested, charged - and later convicted - for the systematic rape, abuse and imprisonment of his only daughter, ‘Katherine’, which spanned decades. He fathered four of her children. Until now, this shocking story has been buried under a complex legal web and Katherine’s insistence on silence so that she could rebuild her shattered life and protect her children. In Behind Closed Doors, and written with Sue Smethurst, Katherine breaks her silence and tells the story of how she survived - and how such degrading abuse went unnoticed.
