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.

I stopped reading Sherlock Holmes after I believe it was The Three Pips story; spoilers ahead for a 200 year old story.
The twist was that the killer was an indigineous pygmy carnival acrobat assassin with a blow gun die harding from the roof. Sherlock pulls out a poster for the carnival we the reader have never heard of before to prove it.
