New evidence shows that the window of the room where Ms. Qianjin hanged herself has signs of being artificially dismantled and re-glued with adhesive, creating the illusion that the suicide scene was a secret room.

The police's target of suspicion this time was the personal maid who had been serving the rich lady at the Lavender Villa.

At the time of the incident, only the daughter and the maid were living in the Lavender Villa.

Therefore, the maid is the person with the greatest suspicion of committing the crime.

However, while the case was still in the investigation stage, the maid committed suicide by jumping off a cliff.

Therefore, the police concluded that the maid committed suicide out of fear of crime, and the entire case was concluded as the daughter's murder.

After reading the police's description of the case in the file, Seriang next to him couldn't help but feel indignant.

"Is it so hasty to accuse someone else of being a murderer?"

"Even if the suspect commits suicide, until there is no conclusive evidence, the case will remain unsolved at best!"

Qin Zhibo remained silent and continued to look at the evidence photos related to the case.

The so-called evidence is actually a pile of screws, half of which were cut off by someone, which is indeed very suspicious.

However, according to Hammertail's explanation, these screws were cut into two pieces specifically for the convenience of breaking through the door.

Wedge the screw cap part back into the window frame and actually secure the window frame with carpentry adhesive.

At night, you can easily break into the villa by simply pulling down the window frame.

The key piece of evidence was that the police found it near the window half a year later. Didn't anyone search there half a year ago?

Moreover, half a year after the case was closed, the police suddenly restarted the investigation, which is also very doubtful.

For the police with this kind of investigation attitude, they have no reason to restart the investigation without any reason.

Unless someone gave the police a reason.

At this time, Qin Zhibo thought that Shikoku Island is located in the south of Japan, which happens to be the territory of the southern detective Koshimizu Nanatsuki.

Could it be that the investigation of the case was restarted because of Koshimi Nanatsuki's intervention?

Qin Zhibo thought for a moment and felt that this was unlikely.

First of all, this case had a great influence at the time, because the deceased was the daughter of a wealthy man and a young girl in her prime. Her death aroused widespread sympathy in the society.

The southern part is originally the territory of Koshimizu Nanatsuki. After learning about the case, he will definitely intervene as soon as possible and will not wait until half a year to solve the case.

It is common sense that every detective knows that clues and evidence in a case will disappear over time.

If Nanatsuki Koshimizu was involved in this case, it is more likely that he was involved from the beginning.

On the contrary, another northern detective Junya Tokizu was a northern detective. It was possible that due to the lag in the transmission of information, it took half a year to start the investigation.

Qin Zhibo was in the car just now and asked Serang Zhenshun to search the Internet about the two of them.

Junya Tokizu was born in Hokkaido and is well-known in Hokkaido. He also has a travel blog.

On his personal homepage, he wrote: Because the case in Hokkaido is almost solved, I want to go outside and take a look.

Koshimi Nanatsuki is relatively less famous. Although he has solved some cases, he is generally relatively low-key.

From a character point of view, Tokizu Junya's character is rather showy, and he is also young and successful, which is somewhat similar to the early Kudo Shinichi.

If you are looking for a case while traveling, you happen to hear about the "Lavender Villa Case" on Shikoku Island, and you happen to pick up the screws that were removed from the mallet tail around the Lavender Villa...

The logic is closed!

Qin Zhibo's eyes lit up and he finally thought about everything clearly.

This case should have involved both Koshimizu Nanatsuki and Tokizu Junya, but one concluded that it was suicide and the other was homicide.

It was precisely because of the major differences in this case that the "Detective Koshien" project was launched.

The person behind this plan should be Nanatsuki Koshimizu.

Because from the current point of view, Tokizu Junya's conclusion has been officially recognized. Although it is incorrect, it has also achieved a "victory".

As the winner, there is no need for him to uncover this dusty past.

What's more, given his tendency to show off, he did not add his name to the files or local case reports, indicating that he may have realized that his reasoning was wrong.

And precisely because Tokizu Junya hid his name, Koshimizu Nanatsuki used "Detective Koshien" to lure him out.

Judging from the candidates invited by Koshimizu Nanatsuki, she knew the identity of the high school detective, but she didn't know who it was.

The fact that she did not invite the more famous "Kudo Shinichi" shows that everyone else has a distinctive feature.

What are the characteristics?

Qin Zhibo held his chin and thought for a long time, but he really couldn't think of it.

What Hakuba Detective and Hattori Heiji have in common is that they both have a father with a tough background, but Junya Tokizu’s father is not also a high-ranking police officer, right?

But now that the search has reached this point, the rest will be much easier to handle.

"Sera, let's go..."

Qin Zhibo closed the file, making Serang Zhenshun, who was still thinking about it next to him, stunned.

"What? Uncle, do you already know the truth?"

"Well, almost."
