This ground-breaking study argues that literature and criminology share a common concern to understand modernity and that this project is often focused upon gender-specific criminality. Central to this concern is duplicity masquerade and performance. These subjects are explored for the first time in relation to criminality with reference to a range of literary and popular texts, from Dickens and Poe through to Toni Morrison and Easton Ellis, in which the traditional boundaries between different genders and sexualities are made more fluid and complex than in traditional criminal narratives.
