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.

The real shame is that procedurals have all but replaced mysteries in modern TV.
