Daily life in the world of famous detectives

"Yes..." Xiaolan and Dr. Chengshi agreed with each other.

At this time, Uncle Mao Li twisted his neck and walked over with a tired face...

"How is it? Dad? Have you found the murderer?" Xiaolan asked.

"Don't be stupid, there are 38 relatives who came to participate in the ritual, it won't end so easily..." Mao Li was helpless.

"Excuse me...my order is..." Dr. Cheng Shi pointed to himself.

"You are the last one in line..." Matsuda also came out from the back room, and then said with rolled eyes.

"Then before the interrogation, I'll wash my face..."

"Officer Matsuda, how many people are there to interrogate?" Conan asked.

"The village chief's daughter Kuroiwa Reiko and her fiancé Murasawa Monday, the candidate Shimizu Masato, the village chief's secretary Hirata and Akira, and Nishimoto Ken who is currently being interrogated. This guy seems to know something, but he just doesn't say..." Matsuda spread his hands.

Conan nodded, Nishimoto Ken, and then he was taken aback: "But Matsuda, don't you need to go in and help?"

"Officer Megure alone is enough. Take this time and tell me the clues you have already obtained..." Matsuda smiled and patted Conan's head.

"You bastard..." Conan rolled his eyes.

"I see, the murderer will continue to kill, which is interesting..." Matsuda rubbed his chin playfully.

At this time, a woman's impatient voice came from the back room, and it became louder and louder, with no intention of stopping...

Matsuda admires this woman a little bit, the legendary Obasan seems to be like this...

"Is there no end? I can't possibly have the motive to kill Mr. Kawashima, it's too much!" Kuroiwa Reiko said loudly.

"Miss Lingzi is amazing, she has been yelling for more than ten minutes..." Xiaolan sighed.

Seeing the helpless look on Officer Mumu's face, Matsuda walked up, stared at the woman fiercely and said, "This is just a routine police matter. If you have any dissatisfaction, you can go to complain..."

"You..." Lingzi's heart trembled when he saw the man's eyes.

"This kid..." Uncle Maori looked at Matsuda who was completely opposite to usual in surprise.

"Wow! Officer Matsuda is so handsome!" Both Xiaolan and Dr. Chengshi looked at Matsuda with admiration.

Conan twitched the corner of his mouth, at this moment, he saw Mr. Nishimoto leaving in a hurry...

"Huh? This guy..." Conan was puzzled and quietly followed.

Suddenly, a beautiful melody sounded, and everyone was shocked. This is, moonlight?

When he heard the voice, Matsuda ran towards the radio room, and then saw Conan in front of the door and Mr. Nishimoto who was frightened to the ground...

Indoors, the village chief's body was already lying on top of the radio station, with a dagger stuck in his back, dripping with blood...

"Father!" Reiko Heiyan, who had rushed over, shouted in pain.

"Miss Lingzi is not allowed to go inside! Call the forensics and autopsy personnel over immediately!" Officer Mu Mu shouted to the little police officer behind him.

"Police, the autopsy personnel have returned to Tokyo in the evening because of Mr. Kawashima's autopsy..."

"What, damn it, at this time..." Mu Mu gritted his teeth.

"I think it's better to let Dr. Chengshi do the test..." Matsuda raised his eyebrows and looked at the woman beside him.

"Me?" Dr. Cheng Shi pointed at himself blankly.

"That's the only way to go, but this will filter out several people. The police here are guarding every door..." Mu Mu pressed his hat and said.

Conan's expression was solemn, and Matsuda also carefully observed the scene.

"I think he was killed a few minutes ago..." Dr. Cheng Shi said after the examination.

"Indeed, this tape has a blank space of 30 minutes and [-] seconds..." Officer Mu Mu looked at the tape in his hand.

"Huh?! Is this the bloody score?" Matsuda saw something unusual on the ground.

"What? Is this a death message?" Uncle Mao Li and Police Officer Mu Mu immediately surrounded him.

"No, if I still have time to write this kind of thing, I would have gone outside to ask for help. This should be left behind by the murderer on purpose..." Conan took out a small notebook, and said while taking notes.

"You idiot! Ah... don't touch the important evidence..." Uncle Maori punched Conan, watched Conan fall on the pattern, and then picked it up.

Conan, who was carried by the uncle, touched his head, then smirked and said, "It should be fine, haha..."

"You little brat..." Mao Li jumped up his veins and punched Conan on the head again.

Looking at the big bag on Conan's head, Maori's mood seemed to improve a lot in an instant...

"Hehe..." Matsuda twitched the corner of his mouth when he saw the big bag flashing on Conan's head.

Wait, if it was the bloodstain a few minutes ago, then the bloodstain should have been destroyed just now, couldn't it be... Isn't the time of death a few minutes ago?

Matsuda looked suspiciously at Dr. Chengshi behind him. He couldn't believe that such a weak woman could be the serial murderer...

Looking at the bloody score on the ground, Matsuda was suddenly taken aback.

"Hey! Kudo, do you understand music?" Matsuda whispered to Conan beside him.

"Huh?!" Conan was stunned.

"Try using the English letters on the piano keys..."

"What letter, brother Matsuda..." Mu Mu asked puzzled after hearing Matsuda's words.

Matsuda didn't speak, but just looked at the pensive Conan.

Conan understood in an instant, and after substituting the English letters on the piano keyboard, it was: "sin, sin, s, resentment, hate, in, here, in, eliminate, eliminate"

"Huh?" Megure and Mouri looked shocked, did they understand it? !

"I see, starting from the left side of the piano keyboard, put in the English letters in order, and then write the message you want to convey on the music score in pinyin, and then you can read it..." Conan laughed.

"That's right, the previous score can also be interpreted in the same way..." Everyone suddenly realized.

"Obviously a sound idiot..." Matsuda curled his lips and said.

"Ming, bai, what, next, one, one, just, yes, you." Conan looked at the previous code again.

"Conan, you are amazing!" Xiaolan was amazed.

"No way, hahaha..." Conan rubbed the back of his head embarrassingly.

"Hahaha, it's that guy! Keiji Aso is still alive!" Ken Nishimoto laughed wildly.

"He was indeed dead. The bones found at the scene of the fire were compared with the tooth shapes. It is absolutely true that it was their family. At that time, everything was burned, and only the music score in the fireproof safe remained. . . . " recalled the old policeman.

"Le, score?!" Everyone was taken aback.

"Where? Where are those sheet music now?" Uncle Maori asked anxiously.

"It's in the warehouse of the public hall, but the key to the warehouse is in the police station..." the old man said slowly.

"Then hurry up and get it!" Mu Mu shouted anxiously.

"Ah? Yes!" The old man hurried out.

Seeing Conan who ran out with him, Matsuda fell into deep thought. It seems that the murder will happen again. Is the matter of Aso Keiji burned to death in the fire really that simple? And that Ken Nishimoto, what is he afraid of?

===Chapter 20 The Truth 12 Years Ago===

"Really, that old man is too slow..." Uncle Maori said impatiently.

"That's right..." Officer Mu Mu also looked outside.

"Just go back, there won't be any murders anyway..."

"That's right, if the sin is eliminated here, then it's over..." Several people also echoed.

"In this case, let's go back first, huh? Brother Matsuda, don't you want to go..." Mu Mu looked at the thoughtful Matsuda and asked.

"Ah... let's go..." Matsuda looked at the piano behind him, with a smile on his lips.

At night, in the silent public hall, two people whose faces could not be seen were conducting a certain transaction. Suddenly, one of them became angry and beat the other person's head hard. Just when he wanted to deal with the traces on the ground, The door opened.

"Who is it?" Conan yelled loudly.

The black figure panicked and immediately broke through the window to escape. Just as Conan was about to pursue him, he was tripped by a figure on the ground covering his head and murmuring in pain.

"Mr. Murasawa?!" Conan didn't have time to think, and then heard Xiaolan's scream.

"Xiao Lan!" Conan was shocked, and ran over quickly, and then saw Mr. Nishimoto hanging in the air.

"Mr. Police, quickly inform Officer Megure and Officer Matsuda!" Conan said.

"No need, I'm already here, and I caught someone who jumped out of the window just now..." Matsuda walked in with a panicked figure.

"Mr. Hirata?!" Conan and Xiaolan said in surprise.

"Huh?! That's Mr. Nishimoto?" Matsuda was taken aback.

"Yeah, and it should have been killed within 10 minutes..." Conan looked at the video tape in his hand.

"Huh? Is that a suicide note?" Conan found a letter from under the hanged body.

"That...is suicide?" Xiaolan asked in surprise.

"No, it's just pretending to be a suicide. There's not even a foothold under his feet. How could he commit suicide?" Matsuda touched his chin and said.

"Then, the murderer is Mr. Hirata?!" Xiaolan covered her mouth and exclaimed.

"No, he's not the murderer, he's just doing some business, I'm right..." Matsuda smiled and looked at the pale man.

"Deal?" At this moment, police officer Mumu and Uncle Maoli finally arrived.

"What's going on... Brother Matsuda..." Mumu looked at Mr. Hirata suspiciously.

"I'll talk about this later, the police department will take a look at the corpse over there first..." Matsuda pointed to Nishimoto who was still hanging.

"Hmm... committed suicide... and a suicide note..." Meguro thought after taking the suicide note from Conan.

"According to the suicide note, he regretted killing Kawashima and Heiyan..."

"According to what Nishimoto said, the five of them had made mistakes and killed themselves in order not to be exposed. These five people refer to Kameyama who was killed two years ago, and Kawashima and Heiyan who were killed this time. They hanged themselves Nishimoto who died and Keiji Aso who set himself on fire 12 years ago..."

"Then...the pianist?" Uncle Maori hesitated.

"What are they doing with these codes..." Mu Mu was puzzled.

"It turned out that Nishimoto sneaked into this room because he was afraid that the secrets of the past would be discovered. He wanted to destroy the music score, but he couldn't find the music score. He chose to commit suicide because he had nowhere to go..." Uncle Mao Li touched Jaw thought.

"That... didn't commit suicide..." Xiaolan and Conan said at the same time.

"Huh? You two..." Molly growled.

"Xiaolan, why do you say that?" Meguro stopped Maori, and then asked.

"Because Officer Matsuda glanced at that person, and then said to Officer Megure.

"And I saw a suspicious figure at that time...it was Mr. Hirata, just now police officer Matsuda brought him back...he knocked Mr. Murasawa unconscious in the piano room, and now he is receiving treatment from Dr. Chengshi ..." After Conan paused, he suddenly looked shocked. Could it be that guy has been waiting there...

"Ah!" Conan suddenly covered his head in pain.

"I didn't say it earlier..." Mao Li curled his lips.

"Huh? Brother Matsuda... huh? What about others..." Mu Mu looked around and asked strangely.

"That guy..." Conan covered his head with a thoughtful expression.

At this time, Matsuda called the old policeman out and asked about Keiji Aso.

"Oh~ those five people grew up together..." Matsuda thought.

"yes..."

"Does Keiji Aso have any relatives?"

"I remembered that besides his daughter, Mr. Aso also had a son. He had a serious illness and stayed in the hospital when he was a child. I remember his name was Chengshi..." the old man recalled.

"Nani? Chengshi..." Matsuda said in surprise.

"By the way, Police Officer Megure wants me to find Mr. Aso's music score, so I will leave the Matsuda Police Department first..."

"Ah..." After answering, Matsuda fell silent. If it is true as he thought, then this is a sad story. For the first time, Matsuda felt that sometimes killing people is a must, because the society There are always some arrogant people who cannot be punished by law.

"Doctor Chengshi, let's go outside for a walk..." Matsuda whispered to Asai Chengshi when he walked into the public hall.

"Ah~ yes..."
