A man hides his money in the garden. It is stolen by the neighbour. He pretends not to know of the theft, and asks the neighbour whether it would be wise to hide other money in the same secret spot. The stolen money is then replaced by the neighbour so as not to arouse suspicion and thus the owner recovers it.
