What mystery readers expect
The core expectation is fair play: the culprit appears early, the clues are visible (even if disguised) and the detective solves the case by reasoning the reader could have followed. Red herrings are welcome; a solution that depends on a fact hidden from the reader is not.
Know your subgenre. Cosy mysteries keep violence off the page, use an amateur sleuth and a close community, and often run in series with a recurring setting. Police procedurals follow the real steps of an investigation. Hardboiled and noir mysteries are darker and more cynical. Locked-room and golden-age styles lean hardest on the puzzle.
Length and structure
Many mysteries fall somewhere between about 65,000 and 90,000 words, with cosy mysteries often at the shorter end. The Full-length preset (60,000 words) fits a cosy well; set a custom target for something longer.
The usual shape: the crime early (often by the end of the first act), a set of suspects each with a motive and a secret, a middle in which the detective's first theory collapses, a second crime or reversal that raises the stakes, and a reveal that recontextualises clues the reader already saw. Plan backwards from the solution: decide what really happened, then decide what the detective notices and when.
How Inkora writes a mystery
Put the solution in your brief: who did it, how, why and the two or three clues that prove it. The planner's synopsis includes the ending, and the chapter outline is where you check that each clue appears in a chapter before the reveal. Edit the outline before writing to move a clue earlier or add a red herring.
Mysteries depend on small facts staying fixed. After each chapter the continuity pass records times, alibis, who was in which room and which objects were found where, and every later scene is written with an instruction never to contradict those facts.
What to put in your brief
The brief is the “Your book idea & instructions” box in the new-book wizard. The more specific it is, the less generic the book. Here is an example, with the settings that go with it:
Cosy mystery, first in a series, no on-page gore. Retired schoolteacher Ruth Penhallow, 67, runs the lending library in a Cornish fishing village. The harbourmaster is found drowned the morning after the regatta. Police call it an accident; Ruth notices he returned a library book overdue for nine years the day before he died. Suspects: his estranged daughter, the pub landlord who owed him money, the vicar, and a visiting yachtsman. Solution: the vicar's wife, protecting a decades-old secret hidden in that book. Clues: the book's missing flyleaf, a tide table, the wife's wet hem at the evening service. Light, warm humour; close third on Ruth.

Common mistakes
- A culprit introduced in the last third, or a solution built on information the reader never saw.
- Suspects with motives but no secrets, so interviews go nowhere.
- Clues so loud that readers solve it by chapter five, or so buried nobody could.
- A detective who solves the case by luck or confession rather than reasoning.
- Letting the times and alibis drift between chapters. Fix them in the brief.
