A wealthy man lives alone in a small cottage. Being partially handicapped he had everything delivered to his cottage. The mailman was delivering a letter one Thursday when he noticed that the front door was ajar. Through the opening he could see the man's body lying in a pool of dried blood.

The villagers loved to talk of Birbal's wisdom and cleverness,
and the emperor loved to try to outsmart him.
