The chest, the apple, and the slave
A fisherman sells a locked chest to the caliph; opened, it holds a murdered woman's dismembered body, and under threat of execution a young man confesses he killed his wife on the false suspicion of infidelity, triggered by a slave boasting he got one of three rare apples from a woman. The husband had bought those apples for his sick wife at great trouble; one went missing, and a stranger's idle boast about possessing it, repeated to the husband, became the 'proof' that condemned her. The slave had simply stolen the apple from the couple's child in the street.
