The first prize in this round is a pearl necklace, which is perfect because it contains a clue about a murderer inside. The necklace is so perfect, in fact, that the first-prize winner is envious of it. He wants to know if there is a way to get the clue out of the necklace so that he can ask the girl about it later. He also wants to find out if the girl is free to come and play at his villa the next day. He asks her if she will tell him about the clue that he wants to share with him in private. She says that she will, and they decide to wait until later. They decide to take their leave of the crown prince. The first day at school is over, and the boy is behaving badly. He tells the prince that he is a bad boy for being so unruly. The prince tells him that the adults have said that the prince is useless, and that the boy should be taught a lesson. He says that he will have to kill the fifth prince if the boy dares to tell him the truth. The boy apologizes for his behavior, but the prince says that the old saying says that even if a teacher is your father for a day, he should still regard the teacher as his father. He goes off to find the girl to ask for the clue.
