The sun is setting and the moon is about to rise. In the office, it seems that Miwako Sato, who has just been reincarnated, is feasting.

"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 been here for a few days, but she didn't expect Narumi Kiyotaka's cooking skills to improve greatly, and the gluttonous worm that she had finally suppressed was instantly hooked again.

"It's cheap, it's cheap, and it's good! How's it going for you to help you look up? Bringing the last dish from the kitchen, Narumi Kiyotaka asked.

"The man named Keiji Aso died twelve years ago, and I looked at the records, and there were obviously a lot of problems in them, and I really don't know how those people were involved in the first place." Sato said angrily, full of a sense of justice, in addition to hating those vicious criminals, she also hated those perfunctory policemen, "By the way, why did you suddenly think of investigating this case?" ”

"Not long ago, Keiji Aso wrote to me!" Narumi Kiyotaka took out a letter and said.

"Ahem!" When Sato heard this, he almost choked, "How can a dead man write to you?" ”

Narumi Kiyotaka handed the letter to Sato, only to see that it read, "Next full moon night...... ...... on Lunaris Island Shadows will begin to disappear again...... Could you please investigate the reason...... Keiji Aso"

After reading the letter, Sato said: "This letter can't be written by him, someone should fake his name." However, looking at the postmark, it was indeed sent from Lunaris Island. What does this letter mean? Why does it seem like there is a sense of foreboding? ”

Narumi Qinglong said: "If my judgment is right, it should be a notice of the killing." ”

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

Narumi Kiyotaka said: "On the night of the full moon, Moon Shadow Island, the time and place are the same as when Keiji Aso died, I heard that Keiji Aso was playing Beethoven's moonlight sonata before he died, and the moonlight dispelled the darkness, which just corresponded to the disappearance of the shadow, combined with Keiji Aso's death, in a sense, it also alluded to the disappearance of life. If a shadow begins to disappear again, it means that someone is dying again, and it is only the beginning, and there should be more than one person who dies in the end. ”

Sato said: "If it's really as you said, why did the other party ask you to investigate?" ”

Narumi Kiyotaka said: "Maybe the other party is still hesitating, hoping that 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 he has to stop it." Sato said, "Without further ado, I'll take a leave of absence tomorrow and go with you." ”

If there is one case in Conan that is the most unsatisfying, the moonlight chapter is definitely on the list, and many years later, the official even remade the animation of this case, and Narumi Kiyotaka still remembers it vividly.

It didn't take long for Conan to come home from school and learn that the two were going to Moonshadow Island tomorrow to investigate the case, and immediately shouted that they were going to go too. Sato felt that it was inappropriate, Conan directly lay on the floor and rolled around, saying that the two went out to play without him, and their acting skills were so high that they chased his mother!

"Take him with you." Narumi Kiyotaka Road.

"Wouldn't it be too dangerous to take Conan with you?" Sato said worriedly.

"Even if we don't take him, with his character, we may secretly follow, which will only be more dangerous." Narumi Qinglong said, this case can be called Conan's life's pain, let him go with him, in a sense, it can be regarded as making up for the regrets of the past.

The next day, the trio drove to the port and took a boat to Moonshadow Island. Lunaris Island is still under the jurisdiction of Tokyo, and the distance is not very far, and the three of them arrive quickly.

On the way here, Narumi Kiyotaka had already analyzed Sato, and the reason why the other party invited him to come to investigate in the name of Keiji Aso should be in the hope that he could find out the truth of the year and bring the real culprit to justice. If the law can't do it, the other side will take matters into their own hands.

It was a case from 12 years ago, and it was difficult to re-investigate it. The three of them first came to the local police station, and there was only one elderly policeman inside. Sato pulled out his ID and identified himself.

The old policeman said: "It turned out to be an adult from the Metropolitan Police Department, is there anything wrong with coming to a small place like ours?" ”

Michiko Sato: "We were investigating a case recently, and we found out that it was related to a person named Keiji Aso, and I heard that this is Keiji Aso's hometown, so I wanted to come and investigate. ”

The old policeman said: "Keiji Aso? He had died twelve years earlier. ”

Sato said: "How did you die?" ”

"According to eyewitnesses who went to the rescue, that night, Keiji Aso locked his family in the house, killed his wife and daughter with a knife, and then set fire to the house, while he repeatedly played a tune in the raging fire, and was eventually burned alive." ”

Sato said, "Who were the witnesses at that time?" ”

The old policeman said: "Think about it, the former village head Isamu Kameyama, the current village head Kuroiwa Tatsuji, the richest local man Hideo Kawashima, by the way, and that Nishimoto Ken." ”

Sato said, "Is there anything left behind by Keiji Aso?" ”

The old policeman said: "The fire burned down the entire house, and the only thing left was a handwritten sheet music in the fireproof safe." ”

Sato and Narumi Kiyotaka looked at each other, the latter nodded, and Sato then asked, "Where is that sheet music now?" ”

The old policeman said, "It should be in the warehouse of the community center." ”

Sato said, "Please take us there immediately." ”

The old policeman said: "Don't worry, I'll find the key first, no one can get in without the key." ”

The key was in the police station, and it took the old policeman nearly an hour to find it. With the key in hand, everyone immediately went to the community center, and after some tossing, they finally got the score.

Miwako Sato flipped through the sheet music, and the thick pile was really just a sheet music, and there were no other words, so I couldn't help but be a little disappointed.

Narumi Kiyotaka and Conan also followed, and with their piano skills, Narumi Kiyotaka quickly saw through the hidden contents, "I see! ”

Sato said, "What did you find?" ”

Narumi Kiyotaka pointed to the marks next to a few notes and explained, "These are sharp (#) and flat (b), and once this mark is added to the note, it will be a sharp or flat semitone. In the case of a piano, it generally refers to the part of the black keys.

This code is actually not difficult to understand, just start from the far left of the keyboard, put the 26 letters of English in turn, and then use the text of the message you want to convey, in the way of romanization, into musical notes and write on the score. By this reasoning, the meaning of this sentence is that I don't want to do anything like this for them again......"

"Isn't that hard to understand?" Sato suddenly felt that his IQ had been critically attacked! Conan was a little annoyed, if he knew the piano, he would definitely be able to see through it at a glance, and consider whether he would also learn some relevant knowledge in the future!
