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

At five o'clock, Conan noticed that Ken Nishimoto had left suddenly, and he followed in curiosity. However, before he could reach the second floor, the exclamation of the village chief of Kuroiwa came from the second floor, and at the same time, the moonlight song played on Moonshadow Island again.

Conan rushed to the second floor, and immediately found Ken Nishimoto standing in front of the door of a room, his legs and feet trembling, looking inside in a daze, and then he fell to the ground, with a look of fear, pointing to the room, wanting to say something, but he was so afraid that he couldn't speak.

Conan rushed forward, looked into the inner room, and was immediately stunned. Not far from the door, the head of Heiyan Village, whose hands and feet were tied behind his back, was lying naked in a pool of blood.

At this time, the Twilight Police Department led the crowd over, and Miss Lingzi shouted, "Dad!" and tried to rush in, but was stopped by the Twilight Police Department and Maori.

The Twilight Police Department ordered, "Call the forensic personnel and the forensic doctor immediately." Then when his subordinates took over, he turned his head and whispered to Maori, "In this way, the scope can be concentrated in these few people." ”

Maori said, "You mean ......"

The Twilight Police Department said, "All entrances and exits here are fully guarded by police officers......

At this time, the forensic doctor who went in shouted, "Dusk police department, the person is still alive." As he spoke, he began to untie the ropes tied to his hands and feet behind the head of the Black Rock Village.

The Twilight Police Department immediately said, "Doctor Chengshi......"

Dr. Chengshi immediately walked into the room and worked with the forensic doctor, and in order to preserve the evidence, the forensic staff kept taking pictures next to him.

Tearing off the tape attached to the eyes of the village chief, Dr. Narumi said, "There are no external injuries to the back of the head and back. ”

The medical examiner said: "There is no lower body, I think I can turn him over." As he spoke, he and several forensic personnel worked together to turn the chubby Black Rock Village Chief over.

Seeing that the head of the village was covered in blood, smelling the bloody smell of the nose, Dr. Narumi coughed, and then said, "It seems that like Mr. Kawashima, there is only a wound between the chest and abdomen." ”

"Are you alright?" asked the medical examiner.

"Ahem, ahem, it's fine. Dr. Sungsil said, then asked, "Hey, what is this?"

Looking at the thing on the heart of the village chief of Heiyan, he touched it and felt it, and the forensic doctor took it off little by little, and then said, "It's a piece of plastic skin or something." ”……

"Alright," Dr. Sung Si said, "I'm going to the bathroom." With that, he rushed out.

The medical examiner said, "Dusk Police Department, the head of Heiyan Village needs a blood transfusion immediately. ”

According to the joint diagnosis of Dr. Chengshi and the forensic doctor, the village chief of Heiyan only needs a blood transfusion at present, and whether there are any other conditions still needs to be observed and more detailed examinations to be determined. His wounds were concentrated in the chest and abdomen, but some of them were no longer bleeding, there were no other external injuries on his body, and the reasons for his unconsciousness could only be identified for the time being, one was because he was given sleeping pills, the second was excessive blood loss, and the third was caused by the impact when he fell from a height.

Shortly after the chief of Kuroiwa was taken to the clinic by the forensic doctor, the forensic staff reported that they could enter the scene.

Looking at the equipment in the room, the Twilight Police Department asked, "What is this place?"

"Broadcast studio. Mr. Murasawa replied.

Looking at the rope on the door, Maori said, "With the size of the head of Kuroiwa Village, I think he is a powerful man." ”

"No," said the forensic officer, "there's a pulley set on the wall, and even a woman can easily pull the Black Rock Village Chief up. ”

The Twilight Police Department asked, "So, what else did you find?"

The forensic officer said: "First, there is a box of recordings in the player, and there is about ten minutes blank in front of it, but the player has traces of automatic tape. The second is that there is a plastic bag, which is the same as the one in the early morning, and there are also traces of adhesive tape, and there are no fingerprints. However, this time there was a drugged handkerchief in it, and a small carving knife that should have been the murder weapon, but unfortunately there were no fingerprints either. ”

At this time, Conan, who had seen the room, asked, "Did you find any sheet music?"

"No," replied the forensic officer, "no sheet music found." ”

Pointing to the large puddle of blood, Conan asked, "What does that look like?"

Squatting down to take a closer look, looking at the ground, covered with blood, faint lines, the Dusk Police Department said, "It does look like there is some pattern." ”

Soon after, a sheet music appeared on the ground, a sheet music made of blood. It seems that he first carved the score on the ground, and then hung the head of Kuroiwa Village, who had been wounded, from above, to let his blood flow in.

"By the way, the Dusk Police Department," Yamazaki said, "the head of Kuroiwa seems to be bleeding more quickly than Mr. Kawashima, and if he is not careful, he may be splashed on his body." ”

The Twilight Police Department immediately ordered, "Go and check them all out at once." ”

Thirty minutes later, the forensic personnel came to report that Mr. Hirata, Mr. Nishimoto, Miss Reiko, Mr. Murasawa, and Mr. Shimizu had no traces of blood on their bodies at all. Dr. Chengshi's bloodstains are exactly the same as in the photo just now, except for the soles of her shoes, but there are no blood stains on the ground where she used to sit, so she has no problem.

At this time, a police officer came in with a photo, which was a photo of the wounds on the body of the village chief of Heiyan after the bloodstains were cleaned up by the forensic doctor.

The Twilight Police Department was surprised and said, "This is ......"

"Isn't this sheet music?" asked Maori, "Lan, do you know each other?"

Looking at the two rows of staves on the head of the village chief Heiyan in the photo, Lan said in surprise, "Ah, this is the score at the beginning and end of the third chapter." ”

"Are you sure it's Beethoven's Moonlight Sonata?" asked the Twilight Police Department.

Lan nodded in confirmation, "Yes." ”

"Dusk Police," Mori asked, "Is it ...... Mr. Kawashima?"

"Yes," the Twilight Police Department confirmed, "Mr. Kawashima is engraved with the sheet music from the beginning and end of the second chapter of the Moonlight Sonata. ”……

In the hall of the village office, everyone was gathered, and the police department said solemnly: "Judging from the fact that Beethoven's moonlight sonata will be played after the crime, leaving a blank time on the tape, and carving a continuous score on the victim's body, and other methods, I think that the prisoner is the same person." ”

Then looking at the people on Moon Shadow Island who were present, the Dusk Police Department continued, "The last time the village chief of Black Rock appeared was around four o'clock in the afternoon, and it was around five o'clock when he was discovered. Although the tape is only ten minutes blank, there are traces of flipping, that is, after four o'clock in the afternoon, it can be the time to commit the crime, so all of you are suspicious. The first discoverer, Mr. Ken Nishimoto, Dr. Narumi Asai who helped just now, Mr. Kazuaki Hirata, the secretary of the village chief, Ms. Reiko Kuroiwa, the daughter of the village chief, and your fiancé, Mr. Murasawa Monday, and Mr. Masato Shimizu, a candidate in the election for the village head. You ......"

"Wait a minute, Dusk Police," Mr. Hirata called, "I've been in this hall since the village chief left. ”

The Twilight Police Department asked rhetorically, "Do you have any witnesses?"

Looking at the others, Mr. Hirata said, "You all know, I've always been here. ”

Mr. Shimizu said, "I'm sorry, I really didn't pay attention, so I ......" and the others didn't speak.

Seeing this, the Twilight Police Department asked, "Mr. Nishimoto, although you are the first person to discover, what are you doing in that kind of place?"

Mr. Nishimoto hurriedly replied, "It was Kuroiwa who called me over." ”

Maori asked, "Did you do it, and then go and pull the door again when the time comes, so that he can be ......"

Mr. Nishimoto hurriedly shook his head and said, "No. ”

"It's Shimizu," reiko shouted, "if it weren't for my father and Kawashima, the position of village chief would have been Mr. Shimizu's." ”

"How is that possible," Mr. Shimizu immediately exclaimed, "not me. ”

Maori said, "Did you know that they had an appointment, so you wanted to borrow Mr. Nishimoto's hand......"

Mr. Shimizu immediately said, "I didn't know there was such a thing. ”

"Uncle Maori," Conan said, "Chief Kuroiwa doesn't have a rope around his neck. As he spoke, he took a photo from Yamazaki and handed it to Mori.

Seeing that his hands and feet were tied behind his back, and there was indeed no rope around the neck of the village chief of Kuroiwa lying on the ground, Maori said, "That's to throw him ......"

Yamazaki said: "After calculation, the height would only give him some minor injuries at most, such as bruises such as swelling. Of course, if he's unlucky, then maybe what's going to happen. ”

"I see," Maori said again, clapping his hands, "that's something under him, waiting for him to fall ......"

"There's something underneath him," Yamazaki laughs, "but it's made of soft plastic skin." As he spoke, he handed over a few more photos.

The Twilight Police Department took the photo, which was a photo of the heart of the head of the Black Rock Village and the thing torn from his heart, and instructed his subordinates to bring the thing, and after reading it, he asked suspiciously, "What is this?"

"A piece of tapered soft plastic skin that has been flattened. The forensic officer replied, then wrapped a piece of paper into a sharp cone, glued it up, removed the excess, and placed it on the table with the tip facing up.

"This ......" took a closer look at the paper cone, and the Twilight Police Department slapped it with his hand, and immediately found that it was a little painful, but when he picked it up, he didn't even break the skin.

Walking to the table and looking at the flattened paper, Maori couldn't help but ask, "Is this the kind of thing?"

The Twilight Police Department muttered to themselves in confusion, "You can pull the door and let people fall?"

Maori muttered to himself suspiciously: "There is no hanging neck, and there is still a soft plastic skin that can't be poked underneath?"

"So," the Twilight Police Department asked, puzzled, "what the hell is this murderer up to?"

"This, this one...... "Holding his chin, Maori said, "yes, he must have injected him with something else." Mr. Kawashima is not being ......"

"However, I never found the syringe. "It seems that the head of Kuroiwa Village will be sent to Tokyo for a detailed examination." Then he instructed, "Call back immediately and ask them to send a helicopter." ”

Hearing this, Miss Lingzi immediately yelled at Qing Shui again, so the two of them quarreled. The Twilight Police Department and Maori stepped forward to dissuade them, and the scene immediately became a mess.

Seeing this, Lan, who had been listening intently to the case, relaxed, and then, inadvertently, saw that Conan was looking at a pamphlet, so he asked curiously, "What are you looking at?"

"I'm looking at the music that was left behind in the scene," said Conan, "and I think it must have been a secret from the murderer, and maybe there was some connection between the rising and falling marks." ”

"By the way," Lan said, "in the case of a piano, those mean black keyboards. ”

"Keyboard?" Conan said, "If that's the case...... Conan exclaimed, "Understand, you're next." This made the men stop at once and look at him together.

"Conan?" said Ran, surprised.

Conan laughed, "This code is very simple if you know the trick." Starting from the left side of the piano keyboard, put the English letters in order, and then write the message you want to convey in the Japanese pinyin style on the top of the score. If you read the score from the public hall based on this clue, it becomes, 'Understand, you're next.'" ”

"Conan, you're amazing. Lan exclaimed.

Maori immediately asked, "And what about the score that was written in blood?"

"This," Conan read, looking at the sheet music transcribed from the pamphlet, "the resentment of the fire robbery is eliminated here." ”

Mr. Hirata was surprised and said, "The resentment of the fire robbery should be ......?"

Miss Lingzi said, "The pianist who committed suicide by arson twelve years ago......"

"Hey...... Mr. Nishimoto laughed horrifiedly, "it's that guy, Keiji Aso, he's still alive." ”

"He did die. Mr. Policeman from Lunaris Island pushed the door in and recalled, "The bones and tooth shapes found at the scene of the fire at the time were all consistent with his, which is absolutely true. Everything was burned down, leaving only the sheet music in the fireproof safe. ”

"Score!" exclaimed in surprise at once from the Twilight Police Department and Maori. Maori then pointed to Mr. Policeman's nose and asked aloud, "Where, where are those scores now?"

"Inside the storehouse of the public hall," said the policeman after a moment's thought, "but the key to the storehouse is in the village police station." ”

The Twilight Police Department immediately yelled, "Then why don't you hurry up and get it." ”

"Yes. With that, the policeman turned around and ran out.

"Wait a minute, Mr. Policeman," called Conan, "I'll go too." So saying, he followed.

Lan shouted, "Conan......"

"I'll go. Yamazaki said and went out. ……
