Gao Cheng quietly goes out of the village office. While he is investigating, he finds the old policeman in the police station on the way to the citizen's residence.

"Uncle, do you still remember the case more than ten years ago? Is Mr. ASO really suicidal? " Gao Cheng asked with great care.

At the end of a minute, the magical state disappeared, but the train of thought did not disappear, leaving him many doubts without clues.

"Well... That's what the eyewitness said," the old policeman recalled slowly. "I remember that what he saw at that time seemed to be the former village head Guishan and Kawashima... Ah, by the way, there were also the village head Heiyan and Xiben, which they saw with their own eyes..."

"Aren't three of them killed this time?"

Gao Cheng thought of his reasoning in one minute and continued to ask, "what's the relationship between the four of them?"

The old policeman nodded and said, "a few of them and ASO grew up together. I remember five of them went to learn piano together when they were young. Later, when ASO became a famous pianist, Xiben often went to participate in his overseas public performances."

With these words, the old policeman responded and said, "ah, now there's only Xiben left."

Gao Cheng smoked at the corner of his mouth.

The old man's reflection arc is too long

Returning to the village office with the old policeman, Gao Cheng continued: "what about doctor Cheng Shi? Does she have anything to do with Mr. ASO? Is it Mr. Aso's daughter? "

The old man shook his head: "Mr. Aso's daughter died in the fire long ago, and doctor Chengshi came only a few years ago, but... Speaking of it, Aso has a son who should still be alive, because he suffered from a serious illness when he was a child, so he has been in the hospital for treatment..."

"Is it true?"

Gao Cheng sighed. Originally, he thought that Asai was just a special hobby of being a fake girl, that is, the legendary woman's dress boss.

Now he knows the real reason why he disguised himself as a woman. I'm afraid it's all about the fire more than ten years ago.

If you're not wrong, maybe the ASO family didn't commit suicide at all, so the head of Heiyan village looked scared before they died

Gao Cheng clenches mudaodongyehu and follows the old policeman into the hall of the village office, where Mu Mu is interrogating the party.

Asai's suspicions have been naturally ruled out, leaving clear water Zhengren, Nishimoto, Hirata and your son's fiance to be suspected on Monday.

As for the secret message of music score, Conan has not been baffled for a long time. This guy just doesn't know enough about piano.

After retelling the interpreted message to the public, Conan's eyes fell on Gao Cheng, who was following the old policeman, and the corners of his mouth rose slightly.

"It's him! It must be him After knowing the score information, Xiben immediately screamed in horror, "that guy is still alive... Aso guier is still alive!"

"He is dead indeed!" The old policeman said, "the bone found at the scene of the fire at that time was also compared with the tooth type. It was their family. This is absolutely right."

Recalling the tragedy, the old policeman sighed: "everything was burned at that time, only the music scores in the fire safe..."

"Music, score?" All the people present were surprised.

"Where are those scores now?" Asked Maori anxiously.

The old policeman recalled slowly: "it's in the warehouse of the citizen Hall... But the key of the warehouse is in the police station, ha ha..."

"Why don't you get it quickly?" Mu Mu black face roars, "go quickly!"

"Ah... Yes!" Startled, the old policeman rushed out of the village office.

"Wait a minute, I'll go with you too!" Conan thought of something and ran after it in a hurry.

On the way to the police station at night, Conan followed the old policeman and pretended to be chatting and asked, "is Mr. ASO really burning his family to death?"

"Well, it's Mr. Guishan, the former village head, as well as Mr. Heiyan, Mr. Xiben and Mr. Kawashima that they saw," the old policeman nodded, suddenly stunned, and responded, "that little brother has asked this question before, and specially asked me about Mr. Aso's son..."

"What?" Conan was surprised, and suddenly thought of Gao Cheng's strange appearance after reading the music score, "Chenghu... Brother Gao Cheng, what did he say?"

……

Village office, Gao Cheng alone called Asai to the outside.

"Mr. Chenghu, what can I do for you?" Asai Chengshi looks at Gao Cheng's back with uncertainty.

"Doctor Cheng Shi, did you send that letter to me? In the name of your dead father... "

Gao Cheng turned to Asahi and said, "I've solved this case, including why you killed those people and why Mr. Xiben was so afraid."

Asai's face changed and he looked at Gao Cheng silently.

"It was nothing when Mr. Kawashima died, but," Gao said in a deep voice, "when it was the turn of Heiyan village head, you showed a big flaw, that is blood. It was not like it was only five minutes later. I think it was probably the use of the automatic turnover device of the broadcasting station... The tape was played from the blank side at the beginning, More than 30 minutes can be saved after turning over automatically.... "

Gao Cheng looked at the silent Asahi and continued: "if you want to hide it from the police, you are the only one who did the autopsy at that time. The reason why you moved Mr. Kawashima to the piano room after he drowned is to support the autopsy personnel. As a doctor, you know the autopsy process very well, I deliberately asked the coroner to take Mr. Kawashima's body back to Tokyo for autopsy... "In fact, I knew from the beginning that you were a man, but I didn't expect that you would be Mr. Aso's son." Gao Cheng looks up at the full moon in the night sky. He thinks of miaoko DouYuan in the previous case, and the director of Luohe in the art museum incident... Even the murderer is not necessarily a bad person, so Asai came to him and Kogoro Maori. I'm afraid he wanted someone to stop him“ Turn yourself in, doctor Cheng Shi. " Asai's face flashed a look of surprise: "don't you give me to the police?" He had heard about the competition between Gao Cheng and Maori Kogoro before. This time, it was a good opportunity to suppress Maori Kogoro... Seeing that Gao Cheng didn't respond, Asai said with a bitter smile: "you are really a very powerful detective, Mr. chenghujun. I didn't think it was so fast, at least Mr. Maori didn't doubt it."“ Although I don't know what happened to Mr. ASO in those years, "Gao Cheng turned and left," I will find out the truth, let Xiben get the punishment he deserves, and bet on my detective reputation. "
