The so-called Mofu Haori is the clothing worn by the Japanese people on traditional ceremonial occasions such as wedding and funeral ceremonies, visits, feasts, kendo, kyudo, tea ceremony, flower arrangement, incense ceremony, garaku, chess way, and calligraphy. The X was originally a break of a samurai family born in the Edo period, and before the Meiji Restoration, the shogunate forbade poor people to wear samurai-style patterns of hatori. It was not until after the Meiji Restoration that Mofuki Haori gradually became the first dress of the Japanese common class. On many formal occasions, it is often suspicious to see people in Western clothes and tattooed Haori in the same room, drinking and talking. These two types of clothing will not be considered rude to civilians to wear to official events.

However, it is not common for Japanese people like Professor Noguchi to stubbornly insist on tattooing Haori. Professor Noguchi's habit is no secret to his protégés who have spent many years with him in Tokyo. But for those in Hokkaido who are just acquaintances, no one necessarily knows about Professor Noguchi's habits. It is precisely because of the asymmetry in information that the murderer finally left enough for the police to officially open a case for investigation.

As soon as Lin Shuyi ended the phone call with Kono-kun, he immediately notified Miki, who was investigating with Aizawa and others. Lin Xiuyi roughly told Miki about the suspicions he had discovered, and Miki couldn't help but be a little excited while being surprised.

"Police, now we can finally apply for a re-investigation into the suicide case of Professor Noguchi. ”

"Another point is that this case is still in the hands of the Hokkaido police, and we must win this case from the hands of the Hokkaido police, so let's tell everyone to withdraw it first and try to submit an application for re-investigation to the Criminal Department as soon as possible. Also, let's talk to the District Prosecutor's Office and withdraw the conclusion of the investigation into the explosion at Kobayashi Shuntaro's house from the District Prosecutor's Office!"

After Lin Xiuyi's arrangement, Aizawa and the others, who were originally investigating around like headless flies, finally found a new direction. Because once a case is determined to be a homicide, the Metropolitan Police Department will devote relevant resources to an all-out investigation. Only in this way can the investigation of Lin Xiuyi and others be regarded as truly permitted by the law.

Now that the suspicion of the first case has been determined, Lin Xiuyi naturally has an interest in continuing to investigate the second case, which is very similar in many aspects. According to the information I received from the Asuda Office, Ms. Minato Fujiki, who was in charge of the cleaning service of Shuntaro Kobayashi before his death, naturally became the focus of Hayashi Shuichi's next investigation.

Lin Xiuyi opened a new page on the computer, and then typed the words "Xishan Hot Spring Qingyun Pavilion", and soon a large amount of information was fed back. Nishiyama Onsen Keiunkan is a traditional ryokan located in Hayakawa Town, Yamanashi Prefecture. It was founded in 705 A.D. and has been in business for 1,300 years. This record is unique in the world. This humble inn in the mountains has become a banner for Japanese business.

When Lin Xiuyi went to the Asuda office to investigate before, he felt a little surprised that this humble housekeeping company could actually be favored by Qingyunkan. But this is not the most strange thing about Lin Xiuyi. In fact, he is more concerned about whether this mysterious Minato Fujiki has anything to do with the death of Kobayashi Shuntaro. So no matter what, Lin Shuichi has to go to Hayakawa Town and meet this Fujiki Minato in person for a while.

An hour later, Miki and the others, who were originally investigating outside, finally returned to the Metropolitan Police Department's Special Search Department. Lin Xiuyi put the photos he had printed out early in the morning and the photos left at the scene of Professor Noguchi's death, and when the two were compared, everyone could see the flaws at a glance.

"How did you find this flaw?"

Miki asked Lin Xiuyi with some curiosity.

"It's nothing, I just searched for information about Eiji Noguchi on the Internet, and I saw the memorial article on the official website of the University of Tokyo at a glance. At that time, I was curious and clicked in. As a result, I discovered Professor Noguchi's interesting habit. I've checked with Professor Noguchi's former students, and they confirmed that Professor Noguchi does have a very obsessive preference for Motofu Haori. Therefore, Professor Noguchi's suicide in a dress is completely the murderer's pretending to be clever. ”

"Police Department, you are really powerful, no wonder even the FBI hired you to guide their work!"

Urashima Yuto looked at Lin Xiuyi with a look of adoration, and Lin Xiuyi hurriedly avoided the other party's eager gaze. He picked up the gel pen in hand, wrote the names of Minato Fujiki and Shuntaro Kobayashi on the whiteboard, and then pasted their photos under the names.

"The main ones we're going to investigate next are these two people, Shuntaro Kobayashi and Minato Fujiki. We already knew about it when we went to the Asuta office to investigate. Mina Fujiki had already left Tokyo at the time of the explosion. I think it's necessary to confirm this. In addition, due to the severe damage caused by the explosion in the home of Shuntaro Kobayashi. This has caused great difficulties in our investigative work. But I think this bombing case can be looked at separately......"

As he spoke, Lin Xiuyi casually wrote Professor Noguchi's name on another whiteboard, and then he wrote the words zopiclone (sleeping pill) under the names of Professor Noguchi and Kobayashi Shuntaro respectively.

"If we discard the special feature of the explosion and carefully recall the two cases, then the first thing that is the same is that zopiclone was found in the stomach solution of the deceased. This is the main ingredient in sleeping pills. Although the dose taken is not enough to kill you, it is really okay to fall asleep. ”

Immediately afterwards, Shuichi Hayashi wrote down two key points of charcoal burning and gas leakage under the names of Professor Noguchi and President Kobayashi, respectively.

From this point of view, there is nothing abrupt about treating Kobayashi's death as a suicide, the difference between the two is that one chooses charcoal burning and the other chooses gas leakage. ”

After Lin Shuyi wrote here, he casually wrote the conclusion of suicide at the bottom of Kobayashi Shuntaro's name.

"Police Department, you mean that the explosion was not a deliberate act carried out by the murderer?" Miki said to Lin Xiuyi with some curiosity.

"Yes, after all, if there is an explosion, it is actually easier to attract attention than suicide. This puts the real killer at risk of exposing the facts of the crime. So, maybe this explosion was really an accident?"
