'Most countries produce crime fiction, but the versions vary according to national self-concepts. America admires the assertive private eye, both Dashiell Hammett’s late 1920s Sam Spade and the nearly as tough modern feminists, such as Sara Paretsky. Britain prefers calm mystery-solvers, amateurs like Hercule Poirot or Lord Peter Wimsey or sensitive police like Ian Rankin’s Edinburgh-based John Rebus. The French seem to favour semi-professionals who are distinctly dissenting – in 1943 Léo Malet’s Nestor Burma stood up to Nazi occupiers nearly as overtly as to Paris criminals.' (Introduction)
