'The plethora of crime stories is such that, in order to succeed, they must either follow a well-trodden narrative path and do so extremely well, or run with a high concept and hope for the best. Having the word ‘girl’ in the title doesn’t hurt. Readers are familiar with genre tropes, to the point of being high-functioning literary detectives, ready to sniff out lapses in logic and to scream at the page (or at a screen) when a plot goes haywire. Treat aficionados of crime fiction with contempt, and you’re dead in the water.' (Introduction)
