Chapter 23

Yesterday, 38 people came to the citizens' pavilion to participate in legal affairs. Therefore, the police asked that the progress of the investigation was somewhat slow, and Bai Yan Zhenyu, who was not suspected and had a good relationship with the nightfall police department, was arranged for the final investigation.

Asai, who took turns with the crowd to watch the night, also received similar preferential treatment. He was arranged to investigate later, leaving him enough time to commit the crime.

As soon as 6 p.m., the inquiry and investigation were still not over. Asai left on the excuse of going to the bathroom and soon returned to the room waiting for the investigation.

About half an hour later, xibenjian, who was originally in the waiting room, suddenly got up and walked out. Seeing this, Baiyan Zhenyu quietly followed him.

"Mr. Xiben, please wait a minute." when Xiben Jian was ready to go to the broadcasting room on the second floor, Bai yanzhenyu shouted at him.

Xiben Jian looked at his watch and asked with a bad attitude, "what's the matter?"

"Mr. Xiben, I'm very interested in this case. I heard that you and the dead Mr. ASO grew up together as good friends. I want to know some details about Mr. Aso's death 12 years ago."

Baiyan Zhenyu knows that xibenjian is most afraid of this matter, so he deliberately uses this question to stimulate him.

Sure enough, after hearing Bai Yan Zhenyu's question, Xiben Jian's face changed greatly. He scolded: "I don't know. If you want to know, ask others. Don't bother me, otherwise I'll be rude to you."

"Eh? Mr. seaborne, I really want to know."

Bai Yan Zhenyu said innocently, "as far as my intuition is concerned, Mr. ASO may have been killed by others."

Xiben Jian shivered all over and quickly denied: "how is it possible that the police could have confirmed that Keiji ASO died of suicide."

"Really? But I always think that case has some doubts. Forget it. Since Mr. Xiben doesn't want to tell me, I'll ask others." Bai yanzhenyu showed a distressed look, and then prepared to turn around and leave.

At this time, a melodious piano sound suddenly sounded on the radio in the citizen's Museum.

"No, this is Maori xiaowulang from moonlight. They followed the sound and went to the broadcasting room with Baiyan Zhenyu. It was found that Heiyan chenci, the current village head, was killed in the broadcasting room with a knife from behind.

"Ah, Dad!"

Seeing this behind the scenes, Heiyan chenci's daughter screamed and wanted to rush into the room. She was stopped by the twilight police department worried that she would destroy the scene.

"Irrelevant personnel are not allowed to enter here," the police department carefully observed the situation in the broadcasting room at dusk, and the opponent ordered: "call the forensic and autopsy personnel immediately!"

Hearing the order of the police department at dusk, the man replied with some embarrassment: "the police department, the coroner wanted to dissect Mr. Kawashima's body, so he went to Tokyo before evening."

"Damn it, the key time is not here." the police department frowned and said with an unhappy face at dusk: "if you transfer people from the police station, it will take some time..."

Asai came over and volunteered, "Twilight police department, I'm a qualified doctor. If you don't mind, I can help..."

"Really? That's great. Please, Dr. Asai." after hearing this, the police department was overjoyed and readily agreed.

Asai Chengshi examined Heiyan chenci's body and truthfully replied, "according to my judgment, Mr. Heiyan's death time was about 30 to 40 minutes ago."

"What? Thirty to forty minutes ago?" the police department was stunned and asked in some confusion at dusk, "but the music we just heard?"

Baiyan Zhenyu stepped forward, pointed to the radio station and said, "look at the nightfall police department, here, this button is on. If I guess correctly, the prisoner should have used the way of rewind playback, trying to take advantage of the loophole in the absence of the coroner to deliberately confuse the time of Mr. Heiyan's death."

"Zhenyu is right," agreed Mao xiaowulang, nodding. "If you use this method, you can prolong the time for at least 30 minutes. Unfortunately, the prisoner didn't expect that the police will allow Miss Cheng Shi to conduct an autopsy."

At this time, a policeman investigating the scene suddenly shouted, "at dusk, under the victim's chair, some strange things were found in the police department."

At dusk, the police department asked his men to remove Heiyan chenci's body and chair, squat down and look at it, and said in surprise: "it seems to be music score."

Maori Kouro also came together and saw the music score written in blood on the ground. He added: "at dusk, the police department also left a music score at the scene of Mr. Kawashima's death. This should be some kind of information deliberately left by the prisoner."

However, the level of Maori Kogoro and twilight police department was limited, and they could not infer the secret code of music score, so they put this clue aside for the time being.

After inspecting the scene, the Mumu police department excluded many people who had no time to commit the crime, summoned the remaining people together and announced: "everyone, Mr. Black Rock was killed at about six o'clock, so those who were still here at that time are suspected of committing the crime."

Heiyan chenci's daughter wiped her tears, pointed to Qingshui Zhengren and said, "officer, I think the prisoner is Qingshui Zhengren. Without my father and Mr. Kawashima, the position of the village head is in his bag."

Qingshui Zhengren didn't kill people. Naturally, he had a clear conscience and denied in a calm voice: "it wasn't me. At that time, I stayed in the waiting room. Many people can prove it to me."

"I think Mr. Xiben is the murderer of Mr. Heiyan," Secretary Hirata pushed his glasses and said, "I found that Mr. Xiben has been looking at his watch frequently at more than six o'clock."

"Don't talk nonsense," xibenjian explained, staring angrily at Secretary Hirata. "I just want to see when it will end."

While everyone was blaming each other, Conan on the other side sat on the small bench and buried himself in thinking about the music score.

"Whoever the prisoner is, he must understand the information in the music before the prisoner kills the next target..."

Conan felt that the music score was a very important clue. He recorded the previous two music scores in the small notebook he carried, and tried his best to crack the information left by the prisoner in the music score.

"The notes in the score are quite chaotic," Conan muttered to himself, concentrating on the notes in the score. "And what's the relationship between the rising sign and the falling sign..."

Xiao Lan, who was sitting on his side, smiled and reminded: "Conan, if it's piano score, it means white keys and black keys!"

"I see. I see."

As soon as Conan's eyes lit up, he immediately understood the writing method of the score code and cracked the information left in the score.
