Police station.

After the search meeting, Gao Cheng and Maori xiaowulang were left alone, because they happened to participate in the rehearsal of tangben concert. Uncle also intervened in the case, but this time Conan failed to get together because of his child's identity.

Uncle was originally a criminal police officer. He was not unfamiliar with the search meeting. Except that he didn't understand it, everything else was OK.

"I see you again, Mr. Maori, and the city detective." Kuroda Bingwei takes the initiative to meet Gao Cheng and Maori xiaowulang.

The case in Nagano county has not been in the past few days. He can bring the police to the police hall in advance. It is also because of the merits of the case. The case inside the county police can be described as a big case. At the same time, when the case was solved, the woodpecker meeting was destroyed for a long time.

Although I've heard about the high success of the city dwellers in the police department before, it's the first time that I've really seen it. It's really unusual, and it's beyond the scope of ordinary famous detectives.

If anyone can solve this serial homicide case, the most likely one is Gao Cheng.

"It's amazing," Maori Kogoro said when he saw Kuroda Bingwei, he was quite familiar with him. "I didn't expect Mr. police to come to the police station so soon."

At the end of the chat, the topic returned to the murder case. Mu Mu took the lead in saying, "anyway, it's a coincidence that all these things happened around Mr. tamamoto. Moreover, I heard that Mr. tamamoto was dissatisfied with the attitude towards life of the four people who were killed. He didn't have any motive at all."

Gao Cheng has some ideas, but he hasn't said them yet.

In his opinion, the two cases may be overlapped. Four people have been killed in Shuikou. It can be seen that the two cases are still alive.

In particular, although qiuting Lianzi couldn't perform in the concert, she didn't suffer much damage. Her voice problem will be better in a few days.

The right starting point for this case should be on the side of Shuikou 4 people. The flute left at the scene of the crime is a direction.

No matter what the intention of the murderer is, it is certain that we can gain some results from this investigation. So at the end of the meeting, he gave his own preliminary suggestion, which is to find out clues that may be related to flute from the investigation of the social relations of 4 people.

"Brother Chenghu," asked Mu Mu Chao, a silent Gao Cheng, "do you really think the investigation from the flute side can produce results?"

"Well," Gao Cheng said with a nod, "leaving a part of the flute at the scene of the murder not only confuses the police investigation, but also has the possibility of revenge. No matter what kind of investigation, there is no mistake in investigating the four people's social relations. I think that once there is a result here, it should be almost the same with the riverside play and miss qiuting."

"I hope so," said Mu Mu. "Fortunately, the criminal should not continue to commit crimes."

"Well, officer Mumu," Gao Cheng suddenly asked, "you should have miss qiuting's address?"

"Ah?"

Leaving the police station, Gao Cheng takes the address from Mu Mu and finds qiuting Lianzi's senior apartment in Tokyo.

Few poor people play music, not to mention the well-known soprano like Qiu tinglianzi. The apartment floor is not high, but it is quite beautiful. They are all very large and the surrounding environment is very quiet.

Generally speaking, stars and musicians like to live in such places.

At this meeting, Qiu tinglianzi was wearing household clothes, not queen like temperament, but was sitting on the bed with thick long hair. She was listening to music alone, with a light look of sadness. She was not strong outside, only a little weak and strong.

"Ding Dong!" The doorbell pulls back qiuting Lianzi's thoughts. After she turns off the music in a hurry, she steps on her slippers to open the door and is surprised to find that Gao Cheng is visiting.

Because the throat has not been stimulated to speak, autumn court pity son can only show a surprised expression, asked to look at Gao Cheng.

"Excuse me..."

Gao Cheng is stunned to see Qiu Ting Lianzi, who lives in the home mode. His thick black long hair is draped in front of him, completely changing his temperament.

"Miss Lianzi, I heard that there was something wrong with your voice, so I came to have a look... Can you come in and have a chat?"

Qiuting Lianzi calms down, lets Gao Cheng go into the room, pours a glass of juice, and writes in the book: "for the previous case?"

"Officer Mumu, they've already asked for you. If you want to, they've said everything, so I won't ask much, just..." Gao Cheng noticed the layout of qiuting Lianzi's room for the first time. There is a group photo and a flute beside the window. In the group photo, qiuting Lianzi and a male musician appear to be a flute player.

No wonder he heard officer Mu Mu say that when he asked about the flute at the concert rehearsal, Qiu tinglianzi had a strange reaction.

For qiuting Lianzi, flute is obviously different

"Shua!" Qiu tinglian son's face is not very good, pull up the curtain, stop Gao Cheng's eyes.

"I'd like to be alone for a while. Could you please go back after your juice?" Qiuting Lianzi wrote in the book.

"Sorry," Gao Cheng said, looking back and shaking his head, "I just want to ask about your concert. The police suspect that someone took the opportunity to add something in the thermos when you borrowed a classroom to practice singing at the tangben Conservatory of music. Do you know who you are practicing there?" Qiuting Lianzi thought about it and continued to write: "the people in the college, as well as the people in the concert hall, should know that it's not something to hide. I practiced singing in the college all this time." Writing here, qiuting Lianzi hesitated for a while and then wrote: "are the police suspecting miss Qiancao?"“ It's true that there are doubts, but there is no evidence to prove that miss Qiancao did it Gao Cheng didn't stay in qiuting Lianzi for too long. It was not suitable to enter a single woman's apartment. After drinking the juice, he said, "in a word, if you can think of any clues, just send me a message. There may be more people injured in this case."“ It's not over yet? " Qiuting Lianzi frowned in doubt“ It's just my feeling, "Gao Cheng said lightly," that the reason why the police feel that the serial murder cases are over is because the barrel, tailpipe and headpipe left at the scene are all together. " For the present autumn court Lianzi, he is not completely without doubt, so he does not explain. Before mastering enough clues, everything is possible. He doesn't just look at the surface, because qiuting Lianzi trusts Meili unreservedly. I think beautiful women don't commit crimes. Maybe uncle Maori is the only one. Of course, judging from the current clues, it is unlikely that Qiu tinglianzi is a criminal. Because of the flute, the police will investigate it sooner or later. It is very difficult for real criminals to leave such loopholes, which contradicts the criminal tactics. Gao Cheng calmly walks out of the apartment building and leaves along the roadside under the gaze of qiuting Lianzi upstairs. No matter whether qiuting Lianzi is a prisoner or not, at least we have gained something here, that is, qiuting Lianzi is not unrelated to the continuous murder case. This alone gave him the confidence to solve the case. Compared with music, detective is really his field Police inspection hall, Sato and Takagi found Mu Mu in a hurry, "found the connection between those four people and miss qiuting!"“ Three years ago, the flute player who went with them to tangben college dormitory in Izu fell from a nearby cliff and died of serious injury due to drunkenness. " Gao Mu took out a picture and said, "the flute player's name is Xiang Maguang. At that time, he was 28 years old. He was the Sixth Graduate of tangben Conservatory of music and the fiance of Qiu tinglianzi."“ Although xiangmaguang's death was not directly related to the four people, it was also handled as an accident at that time, but the reason was that the four people forced xiangmaguang, who was not good at drinking, to drink, so qiuting Lianzi did have a motive. " Sato added. Mu Mu spirit: "good, hurry to contact Chenghu brother!"
