One woman. Two husbands. Four trials. One bloody execution. Last Woman Hanged is the latest book from award winning journalist Caroline Overington. In January 1889, Louisa Collins, a 41-year-old mother of ten children, became the first woman hanged at Darlinghurst Gaol and the last woman hanged in New South Wales. Both of Louisa’s husbands died suddenly. The Crown was convinced that Louisa poisoned them with arsenic and, to the horror of many in the legal community, put her on trial an extraordinary four times in order to get a conviction.
