About Case Fic
A story structured around solving a case — a murder, a haunting, a heist gone wrong — with the plot doing as much work as the relationships. Beloved in procedural and detective fandoms, where writers craft original mysteries worthy of the source material.
Case fic offers the rare double satisfaction of a genuine plot to chew on and characters revealed through how they work, deduce, and depend on each other under pressure.
Common scenarios: Sherlock and John taking an original locked-room mystery from Baker Street to the solution, or the Winchesters working a salt-and-burn that turns out to be something much older.
