It has been 7 months and 20 days since James started his work. Today, he was resting and reading a book. He saw the news on the TV. It said that a phantom thief was going to steal Yellow diamond tonight. James didn't really care about that, but when he heard the owner of that was professor Wilmac, he become interested in it. He called Jack and told him to get ready, they are going to that place. Jack asked: (Are we going to arrest that phantom thief?) James said: (No, that is not what I want. The owner's name is professor wilmac, right?) Jack nodded. James said: (That was a nickname which macmullen used to keep his identity secret.) Jack was shocked. They got ready. They put on their vigilante clothes, then roded the dark wing and went toward that place. When they reached the place, they disguised themself as police officers and went inside. In the room that the daimon was keeped, there were lots of police officers. Now that everything was in it's place, all that remains is that to wait for the phantom thief to come. While they were waiting, the owner come to the room. He said to the person who was in charge: (Thank you for helping in protecting daimond.) The person in charge said: (No problem.) James saw him and made a grim look. It was at midnight that the lights went off. Then the glass breaking voice was heard and someone picked the daimond. The police turned on their torches and saw that phantom thief. The officer in charge said: (So you finally came, phantom thief.) The phantom thief nodded. The police asked: (We are going to arrest you.) The phantom thief said: Ore (If that is what you want, then try it, but I think you should arrest the owner too.) The police was shocked and asked: (What do you mean?) James approached the owner and take out his glass and fake beard. This shocked the police, the officer in charge said: (What is the meaning of this? Who are you?) James said: Koitsu (This guy here is professor Wilson macmullen, the mastermind of a criminal organization.) The police was shocked again. The professor called his men and they got their guns ready. The professor said to the James: (You seems to know me, who are you?) James took out his disguise and said: (Hello again, old professor.) The professor said: Omae (You again?) James said: Ore (Yes, me again.) The professor's men got their weapons ready. James attacked toward them with Jack and knocked them down. But professor escaped again. Then James said: (What are you doing, waiting there? Come and arrest this criminals.) Then the police arrested the professor's men. James and Jack went to the roof and saw that phantom thief there. James said: (You did well knowing he was criminal mastermind.) The phantom thief said: (I only did what I thought it was right to bring him behind bars.) Then he left. James and Jack went back to home. Alfred come and brought them some food. Alfred said: (So you meet some phantom thief, you don't arrest them, master James?)
