Once there lived three thieves. One day, they robbed a wealthy merchant's house. Then, they all went deep into the forest outside the city to share the wealth amongst themselves.
Before doing so, they felt hungry. So, one of them went to the city to get food.
There he purchased food and ate his part. Then, he mixed poison in the leftover food to feed the other two as he wanted to have all the wealth.
On the other side, the two thieves in the forest had also made a plan. They hid behind a tree. When the other thief came with the food, they stabbed him to death. Then, they happily sat down to have their food. But as soon as they ate it, they fell dead as the food was poisoned. So, all of them fell victims of their own evil ways.
