The "One Thousand and One Nights" ("Arabian Nights") contains the earliest known examples of crime fiction. One example of a story of this genre is the medieval Arabic tale of "The Three Apples", one of the tales narrated by Scheherazade in the "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. The story has been described as a "whodunit" murder mystery with multiple plot twists. The story has detective fiction elements.
