To begin, a reviewer’s disclosure: I have known Lucy Sussex since we worked together in the mid-1990s on a research project about nineteenth-century Australian women’s writing. Lucy had already been following the various trails and clues left by crime writer Mary Fortune (1832–1911) along the winding, dimly lit corridors of pre-digital cultural history, as she reports at the end of this book: ‘In 1987 I moved from librarianship to working as a researcher for Professor Stephen Knight … I got the delightful job of largely reading old and vintage crime texts and reporting back … Stephen asked me to look into “Mrs Fortune” [and later] told me that Mary Fortune was no longer his research project, but mine. “You have that gleam in your eye!” he said.’
