Esther Warden was the terror of West End Fremantle and the most dangerous woman in Western Australia. Lilly Doyle kept company with thieves and rogues and was listed as an undesirable. May Ahern was a fallen woman who lured men into dark street corners, tempting them away from the paths of virtue. Esther, Lilly and May were notorious female criminals in early twentieth-century Perth and Fremantle. Criminalised as drunks, prostitutes and vagrants, women committing offences against good order faced a double punishment for their social and gender transgressions. Drunks, Pests and Harlots takes a trip through the underworld streets of Perth and Fremantle from 1900-1939. It offers a glimpse into the lives of criminal women facing close police surveillance, negative media coverage, strict incarceration and institutionalisation. These lives present historical perspectives on female offenders and the development of public critiques of women who fail to meet the expectations of society.
