There was once a mason who had a wife and son. One day the king sent for the mason to build a country-house in which to put his money, for he was very rich and had no place to keep it. The mason set to work with his son. In one corner they put in a stone that could be taken out and put back, large enough for a man to enter. When the house was finished the king paid them and they went home. The king then had his money carted to the house and put guards around it. After a few days he saw that no one went there and took away the guard. Let us leave the king, who took away the guard, and return to the mason. When his money was gone he said to his son: “Shall we go to the country-house?” They took a sack and went there. When they arrived at the house they took out the stone and the father entered and filled the bag with gold. When he came out he put the stone back as it was before and they departed. The next day the king rode out to his house and saw that his pile of gold had diminished. He said to his servants: “Who has been taking the money?” The servants answered: “It is not possible, your Majesty; for who comes here; where could they get in? It may be that the house has settled, being newly built.” So they took and repaired it. After a while the mason said again to his son: “Let us go back there.” They took the accustomed sack and went there, arriving as usual they took out the stone and the father entered, filled the sack, and they departed. The same night they made another trip, filled the same sack again, and went away. The next day the king visited the house with his soldiers and councilors. When he entered he went to see the money and it was very greatly diminished; he turned to his councilors and said: “Some one comes here and takes the money.” The councilors said: “But, your Majesty, while you are saying so, one thing can be done; take a few tubs, fill them with melted pitch, and place them around the walls on the inside, whoever enters will fall in them, and the thief is found.”
