Chapter 1383 Lavender Villa Case
Qin Zhibo looked at the project plan and found that the content did not specify the answer to the locked room technique.

When creating puzzles, the secret room can be realized by Tsuchio and another hired logistics personnel, Kotani Renzo.

Of course, in the case of decryption, it is necessary to explain that Hammertail was knocked unconscious and then put into the secret room.

After the puzzle is revealed, the high school detectives can hand in their answers to Renzo Kotani.

Renzo Kotani then placed the trick under the mat at the toilet door, and the director hidden behind the scenes would judge whose answer was closer to the truth.

After seeing these contents, Qin Zhibo became more certain that the person who organized this "Detective Koshien" was Tokitsu Junya, or Koshimizu Nanatsuki.

It was exactly the same routine as in Twilight Annex, where the answer was placed somewhere and then checked by the organizer hidden behind the scenes.

The organizers of that party were the Food Detective and the Wheelchair Detective.

The organizer of the party was one of the two high school detectives, or both of them were 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 parties are considered to be of the same kind, then the puzzle itself should be the key to the puzzle that the party organizer wants to solve.

For example, in Twilight Villa, the Gourmet Detective and the Wheelchair Detective want to know the true meaning of the treasure code.

And this time's secret room technique should also correspond to an old event.

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

The rules require that Renzo Kotani provide a tool box in each contestant's room. The tools in the tool box include but are not limited to hammers, pliers, screws, woodworking adhesive, wire, etc.

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

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

Toolbox Description To perform a true chamber technique, you need to use the tools in the toolbox.

The large amount of lavender placed in the cottage should be some kind of symbol or hint.

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

"Lavender?"

Hammertail slumped his shoulders, thought for a long moment, then shook his head.

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

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

The reason why Tsuchio was chosen to carry out this plan was not entirely because of his financial difficulties.

So Qin Zhibo further asked, "Lavender should be related to a certain case, maybe it is related to you as well."

"Also, do you really not know this person named Kotani Renzo?"

"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, Hammertail's shoulders trembled in fear 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, the only thing I know about is a case that happened on Shikoku Island a year ago..."

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

Qin Zhibo raised his eyebrows. "So you are the murderer in that case? You are actually a murderer on the run?"

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

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

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

Qin Zhibo: Your hands are not clean now.

"Half a year ago, I disguised myself as a cleaner and went to clean the Lavender Villa which had been idle for half a year."

"In order to facilitate the break-in, I removed the screws from the window of one of the rooms in the villa and glued it shut, thinking I could sneak in at night and take some valuables."

"Kotani Renzo was the one who hired me as a cleaner at that time. I heard that he was originally the housekeeper of Lavender Villa..."

“So I really haven’t killed anyone!”

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

Little did he know that Qin Zhibo had long known that this man who was only good at petty thefts definitely did not have the courage to kill anyone.

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

Therefore, in order to make Chuiwei confess his shameful past, he had to be accused of a bigger crime.

"What happened after that?" Qin Zhibo asked.

"After that..." Hammertail 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 six months ago."

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

"That's all I know."

Qin Zhibo nodded understandingly.

After reviewing the entire incident, it is now almost certain that the organizer's purpose was this "Lavender Villa Murder Case."

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

Fortunately, I have people at the police station.

……

After coming out of the apartment building, Qin Zhibo took the project plan away with him.

Back in the car, Shiliang asked anxiously, "What took you so long to come out? I thought something had happened to you!"

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

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

"Fake director?"

There was a hint of doubt in Sera's eyes, and then he opened the project plan to take a look.

Qin Zhibo drove directly to the Tokyo Metropolitan Police Department.

When they 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 they wanted to review the files of a previous case.

"The case that happened in Shikoku..."

"No problem. The case files of Shikoku must also be reported to the Metropolitan Police Department regularly. I'll have Takagi deliver them to your office later?"

Qin Zhibo replied: "Don't bother. I'm outside the Metropolitan Police Department building right now. Just let me take a look at the contents of the file."

"Okay then, I'll ask Gao Mu to pick you up now..."

After a while, the Metropolitan Police Department's top male host, Takagi Wataru, came out from the main entrance.

"Hello, Mr. Qin."

Gao Mushi 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 her like this, and Sera Masumi was not at all unconvinced, but walked forward and greeted her skillfully.

"Hello, my name is Masumi Sera."

"Ah, hello..."

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

"The file is in the archives room. Please follow me."

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

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

Takagi Shigeru 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 the countless files on the shelves.

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

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

The two of them opened the file and read it carefully.

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

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

The investigation of this case was divided into two phases.

The first stage was after the case occurred, when the police searched the scene and, based on the testimonies of people around them, concluded that the rich girl had committed suicide by hanging herself.

The second stage was half a year after the incident, when the police reopened the investigation and found new evidence at the scene.

New evidence shows that the windows of the room where the rich girl hanged herself had signs of being dismantled and glued back together 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 young lady at Lavender Villa.

At the time of the incident, only the rich girl and the maid lived in Lavender Villa.

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

However, when the case was still under investigation, the maid committed suicide by jumping off a cliff.

Therefore, the police concluded that the maid committed suicide out of fear of punishment, and the whole case was closed as the rich girl was murdered.

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

"Are you so hasty to label someone a murderer?"

"Even if the suspect committed suicide, the case will at best remain an unsolved case until there is definitive evidence!"

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

The so-called evidence was actually a pile of screws, which had been cut in half, which was indeed very suspicious.

But according to Chuiwei's explanation, he had clamped the screws in two on purpose to make it easier for him to break into the house.

Wedge the screw cap back into the window frame, using wood adhesive to secure the window frame.

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

The key point is that these evidences were not found by the police until half a year later near the window. Didn’t anyone search that place half a year ago?
Moreover, the case had been closed for half a year, but the police suddenly reopened the investigation, which is also very suspicious.

For police officers with this kind of investigative attitude, there is no reason for them to reopen the investigation without any reason.

Unless someone gave the police a reason.

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

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

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

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, and her death aroused widespread sympathy in society.

The southern part of the country was originally the territory of Nanatsuki Koshimizu. After learning about the case, he would definitely intervene as soon as possible and would 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 fade over time.

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

On the contrary, Tokatsu Junya, another northern detective, was a northern detective and it is possible that he did not start the investigation until half a year later due to the lag in information transmission.

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

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

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

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

In terms of personality, Tokitsu Junya is a bit ostentatious and successful at a young age, which is somewhat similar to the early Kudo Shinichi.

If you were looking for a case while traveling, and happened to hear about the "Lavender Villa Case" on Shikoku Island, and happened to pick up the screws that Hammertail had removed 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 both Nanatsuki Koshimizu and Junya Tokitsu, but one concluded that it was suicide, while the other concluded that it was homicide.

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

The person behind this plan should be Nanatsuki Koshimizu.

Because from the current perspective, Junya Tokitsu's conclusion has been officially recognized. Although it is incorrect, it has also achieved a "victory."

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

Furthermore, given his flamboyant personality, he did not even include his own name in the files or local case reports, suggesting that he may have realized that his reasoning was flawed.

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

Judging from the person invited by Nanatsuki Koshimizu, she knew the identity of the other party, a high school detective, but she was not sure who he was exactly.

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 anything.

The common point between Hakuba Tanji and Hattori Heiji is that they both have a father with a very powerful background, but it is impossible that Tokitsu Junya's father is also a high-ranking official in the police force, right?

However, now that the search has reached this point, the rest will be much easier.

"Sera, let's go..."

Qin Zhibo closed the file, which surprised Shiliang Zhenchun who was still thinking about it nearby.

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

"Well, almost."

Qin Zhibo smiled confidently, "But for more details, you have to ask her herself~"
