Professor Eiji Noguchi, who committed suicide by burning charcoal, worked at the Faculty of Letters at the University of Tokyo for a long time before his death, and has extraordinary attainments in modern linguistics. However, in addition to being a famous linguist, Professor Noguchi is also a very remarkable translator. He is especially good at translating contemporary literary works from Europe and the United States. This has also brought huge economic benefits to Professor Noguchi, and the royalties paid to Professor Noguchi by the publishing house alone are as high as 15 million yuan per year. With such a retired professor who has no worries about food and clothing, and is respected, Lin Xiuyi couldn't think of any reason why he would commit suicide by burning charcoal at home.

And Shuntaro Kobayashi, who died unexpectedly in the explosion, also has a good life after retirement. He himself served as the principal of a prestigious private school in Tokyo for a long time. He also served as a member of the Tokyo Metropolitan Board of Education. According to the police investigation, Principal Kobayashi alone receives a fixed pension of up to 10 million yuan every year. A happy old man like this died unexpectedly in an explosion caused by a gas leak. In addition to making people feel sorry, there will also be a trace of curiosity. Why would an elderly man who has been engaged in education for many years take sleeping pills while boiling water, is this also an intentional suicide?

Eiji Noguchi and Shuntaro Kobayashi have more in common than that, as they have to live alone due to the death of their spouses and their children living abroad for many years. Thinking that they had lost the care of their wives, the two had to rely on a housekeeping company to deal with daily chores.

It is said that no book is written without coincidence, but as a police officer, the thing I don't believe in the most is the so-called coincidence. From the life backgrounds of the two deceased mentioned above, Lin Xiuyi could find too many similarities, which made Lin Xiuyi feel more and more that there was some possible connection between the two incidents.

Is it a crime committed against the elderly? But there doesn't seem to be anything out of the ordinary in the deceased's bank account! Moreover, knowing how to lead the police investigation to suicide and accident is not something that a rookie can do. You must know that after committing a murderous act, you still have the courage to stay at the scene and calmly dispose of the traces you left at the scene, which requires a very strong psychological quality. So, if this is really a series of crimes, then it is very likely that there are other victims who died at the hands of the murderer.

"Alas, it doesn't look easy!"

Lin Xiuyi stood up from his chair and stretched his stiff neck, then took the photo of Professor Noguchi's suicide scene from the desk and put it back into the information bag. He turned on his computer and typed Eiji Noguchi into his browser, and a large pile of information about Professor Noguchi appeared on the page.

"Teachers and students of the University of Tokyo mourn the memory of Professor Noguchi"

I saw that the official memorial article of the University of Tokyo appeared on the website. Lin Xiuyi immediately clicked in with some curiosity.

This article is an official publication by the University of Tokyo commemorating Professor Noguchi's life's achievements. Most of the entire article is devoted to downplaying Professor Noguchi's suicide, focusing mainly on some of Noguchi's academic achievements and teaching and educating people during his lifetime.

Lin Xiuyi read this article carefully, and there are many photos in the article that Lin Xiuyi has seen for the first time, including photos of Professor Noguchi receiving his degree at Tokyo University when he was young, as well as photos of Professor Noguchi when he traveled overseas and even attended international academic activities, but when Lin Xiuyi saw one photo after another. But suddenly I found a detail that deserves attention.

"Why does Professor Noguchi wear a tattooed haori instead of a suit every time he attends a major occasion?"

Lin Shuichi looked at Professor Noguchi's photo again from beginning to end, except for the fact that he wore a Western dress when he was studying at Tokyo University and studying abroad in his early years. In almost all of the photographs of the official occasions, Professor Noguchi was wearing a tattooed haori. But why did Professor Noguchi wear a suit when he committed suicide?

At this moment, Lin Xiuyi seemed to have finally found a trace of unreasonableness. An old man who was accustomed to wearing tattooed haori suddenly put on a dress when he said goodbye to the world. Could it be that the old man still had the heart to change his style of dressing before he died? If not, then why didn't he wear a tattoo of Fuhaori? Could it be that it was too far-fetched to send it to the dry cleaners and find no replacement for a while. Could it be that someone dressed him in a dress that looked more like he was going to commit suicide?

As soon as Lin Xiu thought of this, he immediately printed out the photos on the webpage one by one, and then he picked up his mobile phone and dialed Kono-kun's number.

"Moses Moses?"

Kono-kun, who received the call, replied in a low voice.

"Kono-kun, does Professor Noguchi like to wear tattooed Haori to formal occasions?"

Lin Xiu didn't wait for Kono-kun to be polite, so he couldn't wait to ask first.

"Hey, but you...... How do you know?"

Kono Shohei couldn't help but feel a little strange when he heard Lin Xiuyi break Professor Noguchi's habit one by one. This little secret is known only to those who are familiar with Professor Noguchi. How did Lin Xiuyi discover this detail?

"So I guessed right, didn't I?"

Lin Xiuyi's hanging heart finally fell, and now he finally caught the clues left by the possible murderer. Now Lin Xiuyi has a lot of confidence to speculate that Professor Noguchi did not commit suicide, but that the murderer deliberately faked all this.

Although Professor Noguchi studied abroad for many years when he was younger, he himself preferred traditional Japanese costumes. I remember when he attended our graduation ceremony, he wore a tattooed ......."

Shohei Kono once again confirmed Hayashi's guess.

"That's the problem! Kono-kun, how likely do you think Professor Noguchi was wearing a suit when he committed suicide?"

Lin Xiu asked Kono Shohei with confidence.

"This ...... How is this possible?"

Kono replied in surprise.

But the murderer didn't know this, and he thought he was clever enough to set up Professor Noguchi's death as a charcoal burner, but he did this to put on a more formal dress for Professor Noguchi, who was used to wearing tattooed haori, which was not easy for those who didn't know Professor Noguchi to see the problem. And Professor Noguchi died in Sapporo again, so the Hokkaido police ignored this detail without knowing it......"r
