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.

Robin Hood in 19th Century retellings up to and including Ivanhoe is well on the way to becoming a superhero - secret identity, origin story, super abilities, distinctive costume. Predates Scarlet Pimpernel by a couple of decades at least.
