Some Boys were playing one day at the edge of a pond in which lived a family of Frogs. My son, said the Mother Mouse, that gentle creature you saw was none other than the Cat. Mercury dived down for the third time, and when he came up again he had the very axe that had been lost. Soon after, the Ant saw a man getting ready to kill the Dove with a stone. The Serpent was furious. When the Frog saw the Mouse, he swam to the bank and croaked: Won't you pay me a visit? He could not have been bigger than this, she said. No, no! Daddy is watching and Daddy will kill him if he should come near! Very well; now dance! And they turned their backs on the Grasshopper and went on with their work.
The evil doer often comes to harm through his own deceit.
