‘There have been at least 19 books written about Sutcliffe, but, apart from one by a French feminist academic and Becoming Unbecoming, all are written by men… But the murders, and the police and press response, drove young women like me to feminism.

Read journalist and activist Julie Bindel’s feature on Una and Becoming Unbecoming, for BBC News magazine.
