The sun sets and the moon is about to rise. In the office, it seems that Mikako Sato, who has just been reborn, is having a feast.

"It's all your fault. The food is so delicious. How can I eat anything else in the future!" Sato complained while eating. She hadn't come for a few days. Unexpectedly, Naruhiro Kiyoshi's cooking skills have improved greatly. The greedy worm that he had finally suppressed was instantly hooked up again.

"It's cheap and you're still good at it! How's the matter that asked you to help me check?" Minghai Qinglong asked.

"The man named Keiji Aso died twelve years ago. I looked at the records and there were obviously many problems. I really don't know how those people handled the case at the beginning." Sato said angrily. She was full of justice. In addition to hating those vicious criminals, she also hated those perfunctory police officers. "By the way, why did you suddenly think of investigating this case?"

"Not long ago, Keiji Aso wrote to me!" Naruhira Kiyoshi took out a letter.

"Ahem!" Sato was almost choked when he heard this, "How could a dead person write to you?"

Naruhiro Kiyoshi handed the letter to Sato, and he saw it read: "Next full moon night...the shadows will begin to disappear again... Please investigate the reason... Keiji Aso"

After reading the letter, Sato said, "It is impossible for him to write this letter. It should be someone who pretended to be his name. However, looking at the postmark, it was indeed sent from Tsukikage Island. What does this letter mean? Why does it seem like there is an ominous premonition?"

Minghai Qinglong said: "If I have a good judgment, it should be a ban trailer."

"Murder trailer?" Sato's face suddenly became solemn, "Are you sure?"

Naruhiro Kiyoshi said: "On the full moon night, Moon Shadow Island, time and place are the same as when Aso Keiji died. I heard that Aso Keiji was playing Beethoven's moonlight sonata before his death. The moonlight dispels the darkness, which corresponds to the disappearance of the shadow. Combined with Aso Keiji's death, it also implies that life disappears in a sense. The disappearance of shadows again means that someone dies again, and it is only the beginning, and more than one person should die in the end."

Sato said: "If it is true as you said, why would the other party ask you to investigate?"

Minghai Qingtou said: "Maybe the other party is still hesitating, hoping someone can stop him. How about it, are you interested in going with me?"

"Since the other party really intends to kill someone, as a policeman, of course I have to stop him." Sato said, "No further ado, I will ask for leave tomorrow and go with you."

If there is any case in Conanli that is the most impressive, the Moonlight Chapter is definitely on the list. Many years later, the official even remakes the animation of this case, which is still fresh in Minami Kiyoshi.

Not long after, Conan came home from school and learned that the two were going to Yueying Island to investigate the case tomorrow, and immediately shouted that they would go there too. Sato felt that it was inappropriate, so Conan lay on the floor and rolled around, saying that the two went out to play but did not take him with him. His acting skills were so good that he was chasing his mother!

"It's better to bring him with you." Minghai Qinglong said.

"Will it be too dangerous to take Conan with you?" Sato said worriedly.

"Even if we don't take him, with his personality, we may follow him secretly, which will only be more dangerous." Naruhiro Kiyoshi said. This case can be regarded as the pain of Conan's life. Letting him go with him together can in a sense make up for his past regrets.

The next day, the three drove to the port and took a boat to Yueying Island. Yueying Island is still under the jurisdiction of Tokyo, and the distance is not very far, so the three arrived quickly.

On the way, Naruhiro Kiyoshi had already analyzed to Sato. The reason why the other party asked him to investigate with Keiji Aso, was that he hoped that he could find out the truth and bring the real prisoners to justice. If the law could not be implemented, the other party would do it himself.

It was difficult to re-invest the case twelve years ago. The three of them first came to the local police station, and there was only an elderly policeman inside. Sato took out his ID and indicated his identity.

The old policeman said: "It turns out that he is an adult from the Metropolitan Police Department. Is there anything wrong with coming to a small place like ours?"

Sato said: "We are investigating a case recently and found it is related to a person named Keiji Aso. I heard that this is Keiji Aso's hometown, so I want to come and investigate it."

The old policeman said: "Keiji Aso? He was already dead twelve years ago."

Sato said: "How did you die?"

The old policeman said: "According to the witnesses who went to rescue, that night, Keiji Aso locked the whole family in the house, first killed his wife and daughter with a knife, and then set fire to the house. He played a song repeatedly in the blazing fire and was eventually burned to death."

Sato said: "Who were the witnesses at that time?"

The old policeman said: "I think about it, the former village chief Ao Kameyama, the current village chief Tatsuji Kuroiwa, the largest local tycoon Eio Kawashima, and by the way, there is Ken Nishimoto."

Sato said: "Does Keiji Aso have anything left?"

The old policeman said: "The fire burned the entire house directly, and the only thing left was a handwritten score in the fire safe."

Sato and Kiyoshi Naruhiro looked at each other, and the latter nodded. Sato continued to ask, "Where is that score now?"

The old policeman said: "It should be in the warehouse of the community activity center."

Sato said: "Please take us there immediately."

The old policeman said, "Don't worry, I'll find the key first. If there is no key, no one can get in."

The key was in the police station. The old policeman searched through it and took nearly an hour to find it. After getting the key, everyone immediately went to the community activity center, and after some trouble, they finally got the score.

Mikako Sato flipped through the music score, and the thick stack was really just the music score, with no other words, and couldn't help but feel a little disappointed.

Naruhiro Kiyoshi and Conan also looked at it. With their piano skills, Naruhiro Kiyoshi quickly saw through the hidden content, "So that's it!"

Sato Ki said: "What did you find?"

Minghai Qinglong pointed to the mark next to several notes and explained: "This is the mark of ascending (#) and mark of ascending (b). Once this mark is added next to the notes, it will rise in halftone or fall in halftone. As far as the piano is concerned, it generally refers to the part of the black keys.

This code is actually not difficult to understand. You just need to put 26 letters in English from the far left side of the keyboard, and then turn the message text you want to convey into notes and write them on the music score in Roman pinyin. According to this inference, the meaning of this sentence is that I will never want to help them do this kind of thing again..."

"Is this difficult to understand?" Sato suddenly felt that his IQ was hit critically! Conan was a little annoyed. If he knew the piano, he would definitely be able to see through it at a glance. Consider whether he would learn some relevant knowledge in the future!
