The Framework
Fair-Play Mystery
Golden-age detective tradition (Christie, Sayers, Knox's Ten Commandments)
Every clue the sleuth sees, the reader sees. The pleasure is the puzzle: a careful reader could solve it one beat ahead of the detective.
Best used for
- • Cozy mysteries and amateur sleuth series
- • Locked-room and contained-cast puzzles
- • Mysteries written as a series with a recurring detective
Core principles
Three suspects, three motives
Each suspect must have means, motive, and opportunity - no last-minute strangers.
Clues hide in habits
Bury the real clue inside a character's ordinary behaviour.
Red herrings tell truths
Every red herring should reveal something real about another character.
The reveal recontextualizes
The reader should re-read the book in their head as the truth unfolds.
