The doctor soon discovered what was wrong with her, but he decided not to cure her right away. Instead each time he visited, he secretly took some of her things. When he had taken away everything, he wanted to cure her blindness and asked for the money.

Now the old woman could see again, she noticed that all her things had gone and she refused to pay the money. So the doctor took her before a judge.
