There was once a famous doctor, who was equally known for his skill as well as his greed.
One day, a woman came to him imploring him to treat her child who was seriously ill. The doctor went with her to her house and cured the child. In gratitude, the relieved mother offered him a silk purse, saying that she had made it herself.
However, the doctor refused, saying that he took only money and nothing else in return for his services. The mother was hurt and asked him how much money he wanted. The doctor said his fee was five gold pieces. At that, the mother reached into the purse and took out ten gold pieces and gave five of them to the doctor.
For once, the doctor's greed proved to be his downfall.
