"Hello sir, do you need any help?"

In the hall on the first floor of the Hokkaido Police Headquarters, two female police officers with face signs saw Lin Xiuyi coming, and immediately bowed slightly and asked Lin Xiuyi. Ｘ

Lin Xiu bowed and returned the salute, and then took out his police account and replied to the other party.

"Ah, actually, I'm also a police officer!"

"Ah, it turns out that you are from the Metropolitan Police Department, I'm really sorry, can I help you?"

"Hey, about a month ago, there was a case of a professor at Tokyo University who committed suicide by burning charcoal, and if it is convenient, I would like to talk to the police officer in charge of this case to find out what happened at that time. Yes...... Please don't get me wrong, it's just because this professor is the mentor of a friend of mine, and this friend of mine has been unable to let go of the news of his teacher's death, so he specially commissioned me to come and ask, that's all!"

Lin Xiuyi said sincerely to the two policewomen in charge of reception. Because he has not yet come into contact with first-hand information, Lin Xiuyi cannot conclude whether this case is really a suicide. According to Shohei Kono, Professor Noguchi is a man who walks his word and will never choose to break himself without fulfilling his ideals. But this suspicion alone cannot be used as strong evidence to overturn the conclusion that Professor Noguchi committed suicide.

"Okay, I understand, please wait here for a while, and I'll notify my colleagues from the Criminal Department to come down and receive you!"

The policewoman in charge of the reception let Lin Xiuyi to the side of the sofa, and then she notified the person in charge of the criminal department by phone, and about five minutes later, a policeman about thirty years old came to Lin Xiuyi.

"May I ask you are the forest police department who came all the way from Tokyo?"

The other party looked Lin Xiuyi up and down, and when he noticed that Lin Xiuyi seemed to be much younger than himself, the other party couldn't help but feel a little suspicious.

"Hey, I don't know what your Excellency is called?"

"Below is Takashi Imai, the head of the Hokkaido Police Headquarters Search Division 1, and I am in charge of the suicide case of Eiji Noguchi. Excuse me, is there anything wrong with you coming from afar?"

Lin Xiu didn't mind when he saw the other party's suspicious look. He stood up, pulled out the business card case from the pocket of his suit, and then pulled out a pair of hands and handed it to the other party.

"Below is Lin Shuichi, the head of the Special Investigation Department of the Metropolitan Police Department's Search Section, and this time I came to Sapporo to meet you, mainly to learn about some specific circumstances when Professor Noguchi committed suicide. Please don't think about it, I don't know much about the specifics of this case. It's just that a friend who happens to be a student of Professor Noguchi, so I accepted the other party's commission and came over to ask about the specific situation, and if there is anything to disturb, please don't blame him!"

Lin Xiu said in a sincere tone, and then bowed to the other party. Imai Takashi saw the other party bowing to him, and hurriedly lowered his head to return the salute, and at the same time, the unhappiness in his heart also faded a lot.

"Since you have come here specifically for this matter, naturally you can't leave empty-handed. Come up with me, and I'll do my best to provide you with all the information you need!"

"In that case, thank you so much!"

Lin Xiuyi followed Imai Takashi through the turnstile passage in the hall, and then the two took the elevator to the floor where the Criminal Department was located. After leading Lin Shuichi to a vacant lounge, Imai Takashi left for a while, and after about ten minutes, Imai Takashi returned to the lounge with a box of materials.

"All the information about Professor Noguchi's suicide is here, and because it's a closed case, all the materials are put together. It might be a bit of a hassle to sort it out. I hope you understand this!"

"Hey, I understand, if you still have work to deal with, I won't delay your time!" Lin Xiuyi saw Imai Takashi's slightly nervous expression, and hurriedly persuaded the other party.

"No need, I'm in charge of Noguchi's case, if there's anything you need, just ask me directly!" Imai Takashi replied with a hint of caution in his tone.

Lin Xiu smiled, not caring about the other party's defensive attitude towards him. He knew very well in his heart that I am afraid that no policeman would like others to point fingers at the cases he was responsible for.

Under the attention of Imai Takashi, Lin Xiuyi punched in the information that the other party had brought over, and then read it carefully. Based on the information provided on this material. The police arrived at the scene only after receiving a report, and the identity of the caller was the cleaning lady hired by Professor Noguchi before his death.

According to the information provided above, the first person to be found at the scene, Kiki Echi, was a dispatched employee of a housekeeping company in Hokkaido, and he went to Professor Noguchi's home at a fixed time every week to clean the house. And the day of the incident happened to be the agreed cleaning date. Kiko Echishiki came to Eiji Noguchi's house at the usual fixed time. opened the door of his house with the key that Hideyo Noguchi gave to the cleaning company、

At first, Echishiki Kiko thought that Professor Noguchi was not at home, but when she opened the door of the study again, she found Professor Noguchi who had collapsed in the room, and at the same time, there was a strong smell of burning charcoal coming from the room. Knowing that things were not going well, Kiko Echishiko immediately notified the police to come and cordon off the scene. The police officer in charge of the investigation eventually found a letter in the pocket of the deceased's jacket when he cleaned up the scene. It was immediately determined that the case was a suicide.

Lin Xiuyi took a general look at the discovery of this case. Then he began to carefully observe the photos of the corpses taken at the scene.

In the photo, Professor Noguchi looks ruddy and his eyes are closed. Lin Xiuyi knew it clearly. This is typical of carbon monoxide poisoning. But in addition, Lin Xiuyi noticed that Professor Noguchi was wearing a well-dressed suit, but he did not wear a tie, and his left and right hands were placed alternately on his abdomen. The expression looks very peaceful,

After Lin Xiuyi put down the photo, he then found the letter that the police found from Professor Noguchi's body. I saw that the letter was printed out of printer paper, and at the same time, only Professor Noguchi's fingerprints were retained on the paper, and the content of the letter was only two short sentences:

"I have failed to live up to everyone's expectations of me, please forgive me for not saying goodbye!"
