Might I introduce you to the works of Maurice Leblanc and his most famous character, the gentleman thief Arsène Lupin, codifier of the phantom thief trope.
He would sent a message telling his victim that he planned to steal their most valuable treasure, and then would leave a letter behind afterwards explaining exactly how he did it.
Mostly known outside of France today from his appearance as Joker’s initially Persona in Persona 5, and his Franco-Japanese grandson, Lupin the Third.
