The earliest known example of a whodunit murder mystery was "The Three Apples", one of the tales narrated by Scheherazade in the "One Thousand and One Nights" ("Arabian Nights"). In this tale, a fisherman discovers a heavy locked chest along the Tigris river and he sells it to the Abbasid Caliph, Harun al-Rashid, who then has the chest broken open only to find inside it the dead body of a young woman who was cut into pieces. Harun orders his vizier, Ja'far ibn Yahya, to solve the crime and find the murderer within three days, or be executed if he fails his assignment. Suspense is generated through multiple plot twists that occur as the story progresses. This may thus be considered an archetype for detective fiction.
