Writing mystery and crime fiction
Mystery fiction has the strictest formal requirements of any genre. The genre promise is explicit: there is a puzzle, and the story will resolve it. Everything else — character, prose, setting, theme — serves that central contract. Breaking it, or being vague about it, loses readers in ways that other genres might forgive.
The craft challenge in mystery is fairness combined with misdirection. The reader should be able to find the solution in retrospect — all the clues are there — but they shouldn't find it before the reveal. This requires precise control of information: what the reader knows, when they know it, and what they're encouraged to notice versus overlook.
Subgenres: cosy, hardboiled, noir
The tonal range in mystery fiction is wide. Cosy mysteries feature low-stakes settings (village fetes, bookshops, tea rooms), amateur detectives, and resolutions that restore order without too much darkness. Hardboiled mystery is urban, morally complex, and concerned with institutional corruption as much as individual crime. Noir is its darkest expression: a world where order is never quite restored and the detective is often complicit in the darkness they investigate.
