About Mystery
Something is wrong and someone must work out what: disappearances, ciphers, impossible crimes, and secrets with bodies attached. Mystery fic includes whodunits, slow-unraveling secrets, and stories where the reader solves alongside the characters.
A fair-play mystery makes the reader a participant, and fandom's deep character knowledge makes the misdirection more fun — you know these people, and you're still wrong.
Common scenarios: A small-town disappearance that the visiting protagonist can't leave alone, or an inheritance with conditions that get stranger the closer anyone looks.
