The Grammatical Investigator in Conan

Qin Zhibo looked at the project proposal and found that the content did not specify the answer to the secret room method.

When creating the puzzle, the secret room can be realized by Tsuchiori and another hired logistics staff, Kotani Renzo.

Of course, in the case of decryption, it should be stated that Tsuchiori was knocked unconscious and then put into the secret room.

After the puzzle is made public, the high school detectives can hand over their answers to Kotani Renzo.

Kotani Renzo then puts the method under the mat at the door of the toilet, and the director hidden behind the scenes will judge whose answer is closer to the truth.

Seeing these contents, Qin Zhibo is more certain that the person who organized this "Detective Koshien" is Tokitsu Junya, or Koshimizu Nanatsuki.

It is exactly the same as the routine of Twilight Annex, putting the answer somewhere, and then the organizer hidden behind the scenes will check it.

The organizers of that party were the food detective and the wheelchair detective.

The organizer of this party is one of the two high school detectives, or both of them are organizers.

Could it be that the high-end bureaus of these detective organizations all like to refer to the stories written by Agatha Christie?

If these two gatherings are regarded as the same kind, then the puzzle itself should be the key to the puzzle that the organizer of the gathering wants to solve.

For example, in the Twilight Villa, the food detective and the wheelchair detective want to know the true meaning of the treasure code.

And this time, the closed room technique should also correspond to an old story.

Qin Zhibo continued to look at the plan and found some clues in the details.

In the details, it is required that Kagu Renzo provide a toolbox for each contestant's room. The tools in the toolbox include but are not limited to hammers, pliers, screws, woodworking adhesives, wires, etc.

In addition, a pot of blooming lavender should be placed in the living room, dining room, toilet, and everyone's room in the cabin.

Obviously, these two special requirements are hints given by the organizer.

The toolbox indicates that the tools in the toolbox are needed to realize the real closed room technique.

And the large amount of lavender placed in the cabin should be a symbol or hint.

Thinking of this, Qin Zhibo looked at Chuiwei who was sitting opposite him again and asked, "What can you think of when you mention lavender?"

"Lavender?"

Chuiwei drooped his shoulders, thought for a long time, and then shook his head.

However, Qin Zhibo knew that lavender must be a hint, and it should be related to these detectives.

Therefore, lavender should be a hint of a certain case.

And Chuiwei was chosen to implement this plan, not entirely because of his tight life.

So Qin Zhibo further asked, "Lavender should be related to a certain case, maybe it has something to do with you."

"In addition, do you really not know this person named Jia Gu Lianzo?"

"You must tell the truth, otherwise if I find out that you are not telling the truth, I will definitely make you pay for it!"

Hearing this cold threat, Chuiwei was frightened and his shoulders trembled, and cold sweat broke out on his forehead.

After a long silence, he lowered his head and began to tell the story.

"Speaking of lavender and cases, what I know is a case that happened on Shikoku Island a year ago..."

"The place where the case happened is called Lavender Villa. A rich girl hanged herself in the room of the villa, so it is also called the 'Lavender Villa Case' by the locals."

Qin Zhibo raised his eyebrows, "So you are the murderer of that case? You are actually a fugitive murderer?"

Chuiwei's expression was shocked, and he quickly waved his hands to deny, "I am not the murderer!"

"I learned about the case half a year after it happened."

"Actually... my original job was a pickpocket..."

Qin Zhibo: Your little hands are not clean now.

"Half a year ago, I pretended to be a cleaner and went to the lavender villa, which had been idle for half a year, to do cleaning."

"At that time, in order to facilitate breaking in, I removed the screws of the window in one of the rooms of the villa, and then glued it with adhesive, thinking that I could sneak in at night to take some valuables."

"Jiya Renzo was the person who hired me to do cleaning at that time. I heard that he was originally the housekeeper of the lavender villa..."

"So I really didn't kill anyone!"

Chuiwei confessed all his past to prove that he was not a murderer.

Little did he know that Qin Zhibo had long known that this man who only knew how to steal would never have the courage to kill.

However, Lu Xun once said that if you want to open a window in a house, you should advocate tearing down the roof of the house, and people will agree to open the window.

Therefore, in order to make Chuiwei confess his unbearable past, he had to put a bigger hat on him.

"What happened after that?" Qin Zhibo asked.

"After that..." Chuiwei continued to lower his head, "I don't know much about what happened afterwards, but I heard that the local police overturned the 'Lavender Villa Case' from half a year ago."

"The rich man's daughter was actually murdered by the maid in the villa, and the maid later committed suicide out of fear of crime..."

"That's all I know."

Qin Zhibo nodded in understanding.

After sorting out the whole incident, it is almost certain that the organizer's purpose is this "Lavender Villa Murder Case".

However, the content of the case told by Chuiwei is too rough and not enough to restore the whole truth of the incident.

Luckily, I have people at the police station.

……

After leaving the apartment building, Qin Zhibo took the project plan with him.

Back in the car, Shira asked anxiously, "Why did you take so long to come out? I thought you had met with an accident!"

Qin Zhibo threw the project plan to her and sat in the driver's seat.

"I talked to the fake director, so it took a little longer."

"Fake director?"

Shira's eyes revealed some doubts, and then he opened the project plan to check it out.

Qin Zhibo drove directly to the Tokyo Metropolitan Police Department.

When he arrived at the door of the Metropolitan Police Department, Qin Zhibo called Officer Megure directly.

After receiving Qin Zhibo's call, Megure thought that the daily performance had come again.

It turned out that he wanted to check the file of a previous case.

"The case happened in Shikoku..."

"No problem, the case files of Shikoku should also be reported to the Metropolitan Police Department regularly. I will ask Takagi to send it to your office later?"

Qin Zhibo replied: "No need to bother, I am outside the Metropolitan Police Department building now, let me take a look at the contents of the file."

"Okay, I will ask Takagi to pick you up now..."

After a while, the Metropolitan Police Department's gold medal male public relations - Takagi Wataru came out from the main entrance.

"Hello, Mr. Qin."

Takagi Wataru came over and shook hands with Qin Zhibo, and saw Shiliang behind him, and asked puzzledly: "Excuse me, who is this..."

"This is my new disciple."

Qin Zhibo introduced it like this, and Shiliang Masumi was not unconvinced at all, but stepped forward to greet him skillfully.

"Hello, my name is Shiliang Masumi."

"Ah, hello..."

Sera grinned, which made Takagi a little stunned. He was obviously a boy, but he was cute when he smiled?

"The file is in the archives room, come with me."

Led by Takagi Wataru, several people came to the archives room.

The huge archives room concentrates major case files from all over the country, but 80% of them are from the Tokyo area alone.

Takagi Wataru is worthy of being the gold medal data investigator of the Metropolitan Police Department. In just 10 minutes, he found the file of the "Lavender Villa Murder Case" from countless files on the shelf.

"The file is here, I won't bother you for now."

Takagi left very sensibly, leaving Qin Zhibo and Sera Masumi.

The two opened the file and read it carefully.

Just on the way to the Metropolitan Police Department, Sera Masumi finished reading the project plan obtained from the Tsuchiwei, and with Qin Zhibo's introduction, he had a general understanding of the ins and outs of the incident.

After reading the "Lavender Villa" case file, the context of the whole incident became clearer.

The investigation of this case is divided into two stages.

The first stage was after the case happened, the police searched the scene, and combined with the confessions of the people around, they believed that the rich lady had hanged herself.

The second stage was six months after the case, when the police reopened the case investigation and found new evidence at the scene.

The new evidence showed that the window of the room where the rich lady hanged herself had traces of being dismantled by humans, and was glued back with adhesive, creating the illusion that the suicide scene was a closed room.

The police's suspect this time was the personal maid who had been serving the rich lady in the Lavender Villa.

At the time of the case, only the rich lady and the maid lived in the Lavender Villa.

So the maid was the person with the greatest suspicion of committing the crime.

However, when the case was still in the search stage, the maid jumped off the cliff and committed suicide.

So the police determined that the maid committed suicide out of fear of crime, and the whole case was closed as the rich lady was murdered.

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

"Are you so hasty to identify someone as a murderer?"

"Even if the suspect committed suicide, the case can only be considered an unsolved case at most before there is decisive evidence!"

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

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

But according to Chuiwei's explanation, these screws were just clamped in two for the convenience of breaking into the house.

The part of the screw cap was wedged back into the window frame, and the window frame was actually fixed with woodworking adhesive.

When it was night, as long as the window frame was pulled down with force, it would be easy to break into the villa.

The key is that the police found these evidences near the window half a year later. Didn't anyone search there half a year ago?

And the case has been closed for half a year, and the police suddenly reopened the investigation, which is also very suspicious.

For the police with this attitude of investigating the case, they have no reason to reopen the investigation without any reason.

Unless someone gives 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 Nanatsuki Koshimizu.

Could it be that the case was reopened because of Nanatsuki Koshimizu's intervention?

Qin Zhibo thought about it and felt that this possibility was not great.

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

The south was originally Nanatsuki Koshimizu's territory. After learning about the case, he would definitely intervene as soon as possible and would not wait until half a year later to solve the case.

The clues and evidence of the case will fade over time, which is common sense that every detective knows.

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

On the contrary, the other northern detective, Junya Tokizu, is a northern detective. It is possible that he started the investigation half a year later due to the lag in information transmission.

Qin Zhibo was in the car just now and asked Masumi Sera to search the situation of the two on the Internet.

Junya Tokizu was born in Hokkaido and is quite famous in Hokkaido. He also has a travel blog.

On his personal homepage, it is written: Because the cases in Hokkaido have been solved almost, I want to go out and take a look.

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

In terms of personality, Junya Tokizu is more showy and successful at a young age, which is somewhat similar to the early Kudo Shinichi.

If you are looking for a case on the way to travel, you happen to hear about the "Lavender Villa Case" on Shikoku Island, and you happen to pick up the screws removed by Hammertail around the Lavender Villa...

The logic is closed!

Qin Zhibo's eyes lit up, and he finally figured everything out.

This case should have been participated by Nanatsuki Koshimizu and Junya Tokatsu, but one came to the conclusion of suicide and the other was homicide.

It was because of the major disagreement on this case that the "Detective Koshien" project was launched.

And the person behind this project should be Nanatsuki Koshimizu.

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

As the winner, he does not need to uncover this dusty past.

Moreover, with his love of showing off, he did not add his name to the files or local case reports, which shows that he may have realized that his reasoning was wrong.

And it was because Junya Tokatsu hid his name that Nanatsuki Koshimizu used "Detective Koshien" to lure people out.

From the candidates invited by Nanatsuki Koshimizu, she knew the identity of the other party's high school detective, but she did not know who it was.

She did not invite the more famous "Kudo Shinichi", which shows that the others have a significant feature.

What is the feature?

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

The common point between Hakuba Tan and Hattori Heiji is that they both have a father with a strong background, but Tokatsu Junya's father is not also a high-ranking police officer, right?

However, since the investigation has reached this point, the rest will be much easier.

"Sera, let's go..."

Qin Zhibo closed the file, which surprised Sera Masumi who was still thinking next to him.

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

"Well, almost."

Qin Zhibo showed a confident smile at the corner of his mouth, "But for more details, you have to ask her herself~"
