After tellingseveral of his friends about the theft, Dimitri found out that his neighbour,Aleko, had suddenly acquired a new lamb. Dimitri immediately went to Aleko'shouse and angrily accused him of stealing the lamb. He told him he had betterreturn it or he would call the police. Aleko denied taking it and led Dimitriinto his backyard. It was true that he had just bought a lamb, he explained,but his lamb was black. Ashamed of having acted so rashly, Dimitri apologisedto Aleko for having accused him. While they were talking it began to rain andDimitri stayed in Aleko's house until the rain stopped. When he went outsidehalf an hour later, he was astonished to find the little black lamb was almostwhite. Its wool, which had been dyed black, had been washed clean by the rain!
