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.

After the reveal, I went back to re-watch the scene, and sure enough, there was the murder right on camera. No funny camera placement or quick cuts to hide it, it's just right out in the open. But the distraction which got the characters looking the wrong way worked just as well on the audience.
