The Peasant's Clever Daughter

A peasant found a golden mortar and as an honest and loyal man, he decided to give it to the king. The king was however not pleased. He wanted the pestle as well. He thought that the peasant had stolen it but as you know no such thing had happened. The peasant got locked up in the castle. If he had listened to his wise daughter's words, he would not be imprisoned. The king heard the poor man's grumbles and his curiosity awoke. Was this girl really that smart? He was going to find out.
