Wednesday, April 3, the sixteenth day of the lunar calendar, evening.

The events on Lunaris Island "began to disappear" as predicted in the letter of commission. Following the attack on the beach, Mr. Hideo Kawashima, the island's biggest bourgeoisie and candidate for village head, Mr. Tatsuji Kuroiwa, the current village head and candidate for village head, was also attacked in the broadcast studio of the village office.

At Ran's prompting, Conan unlocked the code left in the score, and the incident was indeed related to the pianist Keiji Aso, who committed suicide by arson twelve years ago. But Mr. Policeman, who is supposed to be retired on Moonshadow Island, confirmed that in that fire, Aso Keiji had nothing left but a sheet music, and that all of his people were burned, as evidenced by bones and tooth shapes.

Knowing that there was a sheet music left that year, the Twilight Police Department immediately asked Mr. Police to get it, and Conan and Yamazaki followed.

On the way to the village police station, Conan asked, "Hey, Mr. Policeman, did Mr. Aso really set fire to his family with his own hands?"

"Because there were four witnesses who saw it," Mr. Policeman replied, "Mr. Kameyama, the former village chief, and Mr. Kuroiwa, as well as Mr. Nishimoto and Mr. Kawashima." ”

"Is there anything to do with those four people?" asked Conan Right.

Mr. Police replied, "Including Mr. Aso, all five of them are classmates. ”

"So," Conan asked again, "what about the big brother named Murasawa?"

"Ah, that fellow, he came to this island three years ago, and was engaged to the daughter of the village chief a few days ago," replied the policeman, again, "but the village chief has always been against it. ”

Conan continued to ask, "What about the village chief's secretary, the man named Hirata?"

Mr. Policeman continued, "The man was very slick, and although I don't know what he did, I often saw him and Mr. Kawashima sneaking around at the public hall. ”

Conan then asked, "What about Mr. Shimizu?"

Mr. Policeman then replied, "He has a strong sense of justice and is very loved by the fishermen. ”

"Oh, so they are like this. Conan muttered to himself.

"Do you have anything else to ask?" said Mr. Policeman, smiling, "Little Detective Brother." ”

"Well, no, no. Conan immediately smiled sheepishly.

When they arrived at the village police station, Mr. Policeman went in to look for the key, and Conan and Yamazaki stood at the door chatting.

Yamazaki smiled, "This police gentleman doesn't seem to be confused at all. ”

Conan smiled, "It's really the right question." ”

"Now it seems," Yamazaki said, "that Mr. Nishimoto was a key figure. ”

"Yes," said Conan, "is with Mr. Kawashima and Mr. Hirata. ”

Yamazaki said, "Last night's figure can basically be confirmed to be one of the two of them. ”

"yes," said Conan, "I just don't know why he's standing outside the window." ”

"Maybe he's curious. Yamazaki smiled, "By the way, aren't you going in to help? It's also a detective's job to find things, right?"

Looking at the dusty situation inside, Conan said: "This kind of thing, let him do it himself." ”……

An hour later, Yamazaki asked, "Are you sure he doesn't need help?"

"I'd rather wait another hour. Conan replied earnestly.

"Ah, I found it," exclaimed the policeman in surprise at the village police station, "and I said it should be around here, and this is the key, this is it." ”

"It's alright," Yamazaki laughed, "and I'm wondering if I'm going to smash the door open the warehouse door." ”

Conan laughed, "Maybe in an hour, the Dusk Police Department will agree." ”

"Mr. Policeman," Lan shouted, "it's too slow, everyone is impatient, and they're already back." ”

"W-what?" Conan asked in surprise, "All the suspects have gone back?"

Lan said: "Everyone thinks that the last message left by the murderer is that the resentment is eliminated here, indicating that it is over, so there should be no more incidents." ”

Conan immediately said, "I'm going to take a look at the public hall." With that, he ran away.

Lan immediately shouted, "Wait a minute, Conan. But Conan ignored her, and continued to run without looking back.

"Mr. Policeman, let's go over and have a look. Yamazaki explained, "Although I don't know how the murderers are ranked, the first chapter of Moonlight hasn't appeared yet. ”……

On the way, the three of Yamazaki met Conan, and the four of them arrived at the public hall together.

After entering, Conan immediately urged, "Mr. Policeman, hurry up and open the warehouse." ”

"Good, good, good. "Don't be in a hurry. ”

At this moment, there was a "bang" in the piano room, as if something was being struck, and Conan immediately said, "There seems to be a sound in the piano room." So saying, he ran in.

Conan went in to see, in the dark piano room, a figure was standing next to the piano, saw him come in and immediately broke through the window and escaped, Conan hurriedly chased after him, but immediately tripped and fell, got up and took a closer look, Mr. Murasawa was lying on the ground.

Conan immediately stepped forward and put his hand on Mr. Murasawa's neck, then breathed a sigh of relief and said, "He's still alive." ”

Yamazaki said, "Mr. Police, hurry up and inform the Twilight Police Department and the doctor." ”

"Okay. Mr. Policeman said and left.

At this moment, the music sounded, and Beethoven's Moonlight Sonata sounded again on the Isle of Moonshadow.

"Outside. Conan immediately rushed out, and Yamazaki and Ran immediately followed.

Running along the sound, a person lay on the beach, it seemed that the whole person was completely underwater, and finally ...... Hey, Conan suddenly found that a thick pipe was erected there, and when he looked at it again, it seemed to be inserted in the man's mouth, and then he saw that it was Mr. Nishimoto, who should have his hands and feet tied, also naked, and his eyes were also tapped, but it didn't seem to bleed much, and the surrounding sea water was only faint blood red.

Yamazaki immediately went down and dragged Mr. Nishimoto up, but as soon as he came up, Mr. Nishimoto only coughed a few times and fainted before he could say a word.

Relieved, Conan found that on the reef not far away, there was a stack of music scores pressed under the tape recorder, and he stepped forward to turn off the tape recorder, and then read the top sheet music, strange, how to decipher it with the method just now.

Looking at the wound between Mr. Nishimoto's chest and abdomen, because he had just come out of the sea and did not bleed much, the wound was relatively clear, Lan immediately recognized what the three rows of staff that had been carved were there, so he said, "This is ...... It's weird. ”

"What's strange?" Conan asked, immediately turning his head.

"That's the score at the beginning and end of the first chapter, but the beginning is repeated," Lan said. The first row is the beginning, the second row is the end, and the third row is the beginning. ”

"Start again?" Walking up to Mr. Nishimoto and looking, Conan said, "Sister Lan, can you go over there and have a look."

Looking at the top sheet music, Lan said, "Well, this should be a normal sheet music. ”……

Soon after, the Twilight Police Department led the team to the piano room of the public hall. After the diagnosis of Dr. Narumi and the forensic doctor, the cause of Mr. Murasawa's coma should be a concussion, and then they went to the beach.

As soon as the diagnosis was confirmed, the police officers came up and prepared to lift Mr. Murasawa onto a stretcher and take him to the clinic. To Miss Reiko, who was watching the police lift Mr. Murasawa, the Twilight Police Department asked, "Miss Kuroiwa, I want to ask you, it's so late, what the hell is Mr. Murasawa doing here?"

"How could I know about such a thing. Miss Reiko immediately exclaimed.

At this time, Conan noticed that when Mr. Murasawa was being carried onto the stretcher, something had fallen out of his pants pocket, so he stepped forward to pick it up. Seeing this, Miss Lingzi immediately snatched it and shouted, "Don't mess with Monday's things, okay." ”

Looking at the little hammer-like thing, the Twilight Police Department asked, "What is this?"

"I don't know," said Miss Reiko, "but I'm always careful to carry it on Monday." ”

"Ah, isn't that a tuning hammer. "That's the tool used to tune the piano." ”

"Tuning hammer?" said the Dusk Police, "is he here to tune this piano?" and then, seeing that no one answered him, he said, "Forget it, let's talk about it when he wakes up." Then he asked, "By the way, why is he different from the others? he has not been stripped of his clothes, nor has he been engraved with musical scores, nor has he even been tied up, and his eyes have not been taped." ”

"By the way," said Conan, "I saw a suspicious man who had escaped through the window. ”

"Smack!" Maori immediately planted a large mushroom on Conan's head and scolded, "Why didn't you say it earlier." ”

Conan sat down on the ground in a daze, and then hugged his head and shouted, and Lan immediately complained, "Dad!"

The Twilight Police Department asked, "Do you mean that the murderer has someone else?"

Maori said: "Maybe Conan broke through the hide, and before he could make a move, he hurriedly broke the window and escaped." ”

"But," Conan said again, "there were no sharp weapons, drugged handkerchiefs, or plastic bags with duct tape on them, which were his tools for committing crimes." ”

The Twilight Police Department asked, "What did Mr. Murasawa get hurt?"

The forensic officer said: "The murder weapon this time is a piano bench. ”

"By the way," Maori said, "he must have been bumped into when he came back from the beach, so he was in a hurry......"

"It's quite possible," said the Dusk Police Department, "and let's go to the beach and have a look." With that, he walked to the front door.

Passing by the warehouse and seeing that Mr. Police was still inside, the Twilight Police Department couldn't help but ask, "Can't you find the sheet music that Mr. Aso left behind?"

"Twelve years ago," replied Mr. Policeman, "who knows where it was placed." ”

"Then you can look for it slowly," said the Dusk Police Department and went to the beach.

As soon as Mori arrived at the beach, he asked, "Dr. Narumi, how is Mr. Nishimoto?"

"I can confirm that I was given sleeping pills. Dr. Sung Sung replied.

"But," said the medical examiner, "based on Mr. Kawashima's example, other possibilities cannot be ruled out." ”

"So," said the Dusk Police Department helplessly, "helicopters are going to be called again." ”

Looking at the three rows of staves carved on Mr. Nishimoto's body, Maori asked, "Strange, how can this have an extra row of staves?"

Yamazaki said, "And it doesn't seem to have left a code word. ”

After taking the sheet music that had been packed one by one, and interpreting it in the same way that Conan had said earlier, Maori asked, "Why can't I read it, what is written on it?"

"Maybe it's the score. Yamazaki said.

"Ran. Maori said and handed the sheet music to Ran.

"I'll see," said Ran, "well, it's a complete sheet of Beethoven's Moonlight Sonata." Ah, strangely, this extra one is ......"

It was a sheet of music with a staff lined up, but only a few notes from the first line, and Maori asked, "What's wrong with that?"

"The bottom line on Mr. Nishimoto, exactly like the one above," said Ran, "is the beginning of the first chapter of the Moonlight Sonata." ”

The Twilight Police Department asked, "What about the tape this time?"

The forensic officer replied, "This time there is about thirty minutes of blank time. ”

"Isn't that the time since I came out of the village office?" said Mori, "and in that case, the other five people except Mr. Nishimoto are all suspicious." ”

"What else have you found?" asked the Dusk Police Department again.

"This time, except for the plastic pipe left at the scene, no plastic bag was found," the forensic officer said, "and there are still no fingerprints." ”

"Alright," the Twilight Police Department ordered, "go and bring all the suspects to the village hall to assemble." With that, he left.

"Yamazaki," Conan whispered, "come with me to the piano room." ”

Yamazaki smiled: "It seems that you, who went one step first, have also gained something." ”……
