He leaves a sack of money with a note in the town, claiming it is a reward for a good deed done years ago by one of the town's citizens. The note sets off a chain of events as Hadleyburg's leading citizens compete to prove their claim to the reward, even resorting to dishonesty and deception.The story explores themes of hypocrisy, self-righteousness, and the corrupting influence of greed and moral superiority.
