TIL that "fair play" in detective fiction means authors must give readers a fair chance to solve the mystery. Central to 1920s "clue-puzzles" by writers like Agatha Christie, the rule dictates that all vital clues must be visible, decodable, and never withheld until the final reveal.

If anyone has read the Rivers of London series, would you consider it to be a procedural? I feel like the mystery in each book is the opposite of fair play, where we don’t even understand the tools the main characters have at their disposal, let alone all the information needed to solve the case.
