The Grammatical Investigator in Conan

Qin Zhibo's eyes fell on the ventilation window on the door, and he immediately thought of a way to create a secret room.

Just use a cylinder of sufficient length to slide the key into the drawer along the middle of the cylinder, and then use it to slide the notebook onto the key and push the drawer back.

As for the specific objects used to achieve this technique, Qin Zhibo looked at the vase placed on the low cabinet.

【Survey√】

[There are fragments of posters on the fake flowers in the vase. They were probably not placed there intentionally]

The vase is located more than one meter above the ground. If the poster was dropped directly on the floor at the door, it would not have been dropped here.

The existence of this investigation point shows that the murderer indeed used the ventilation window to throw the torn posters in from the outside.

Countless poster fragments were thrown from high places, floating in uncertain directions, and one of them happened to fall on the vase on the low table next to it.

The purpose of tearing up the posters, apart from creating mystery, can only be to dispose of the tools.

Posters are one of the tools for committing crimes.

Qin Zhibo stared carefully at the countless poster fragments on the floor, squinting his eyes slightly.

Suddenly, he seemed to see something and turned around to turn off the light in the room.

The room suddenly became dark, only the light source in the corridor could illuminate it.

This step of operation shocked everyone standing at the door, with doubts on their faces.

Although among them, except for the man with glasses, they got a taste of how detectives solve crimes on the spot by inviting the Maori family to do a show last time.

But according to common sense, the detective should want the light to be brighter, so that it is easier to find clues at the murder scene.

But the famous detective in front of him did exactly the opposite...

However, they didn't know that Qin Zhibo had already taken advantage of this low-visibility environment to see new investigation points among the poster fragments.

【Survey√】

[Some poster fragments have damage on their edges. How could this be caused? 】

The description of the investigation is a question, which means that as long as we solve this problem, we will be close to solving the method used by the murderer.

Qin Zhibo followed the position of the light spot, stepped on the edge, and picked up the poster fragments from the chaos.

The fragment of this poster is located at the very edge of the whole poster, and the edges are covered with layers of squeeze marks.

This kind of mark is somewhat similar to the wrinkles on Jiangxiang pancake.

However, the paper used to print posters is relatively hard. If the poster is placed on a flat surface, it will be difficult for humans to make such marks.

unless……

Qin Zhibo used the light from the investigation point to pick out many poster fragments with the same traces among the poster fragments.

These fragments all have one characteristic.

It is located at the edge of the poster, and the edge is completely scratched.

This is obviously a special mark made by the murderer after using these posters.

In an instant, the murderer's method of using these posters became clear to Qin Zhibo.

Next, all that's left is to completely decipher the secret room between the meditations on the first floor.

"Let's go back downstairs."

Qin Zhibo turned around and walked out of the room, locking the door with his backhand to prevent others from entering the scene.

On the way back to the first floor, the short-haired girl finally couldn't help her doubts and asked.

"Um... Mr. Detective, where is the student Kuroba who came with you?"

After her reminder, others also remembered that they had not seen Kuroba Kaito for a long time.

Qin Zhibo was stunned for a moment and could only explain forcefully, "He is still having diarrhea and cannot come out of the room."

Upon hearing this, the short-haired girl frowned, put her hands in front of her heart and worried: "But if you keep doing this, will your intestines and stomach be damaged? Do you need to send him to the hospital..."

"It doesn't matter, it doesn't matter, this kid has a strong body."

Qin Zhibo waved his hand and was temporarily fooled.

However, Kuroba Kaito did disappear for a while, and I don’t know where this naughty boy went.

Solve the case quickly and go find him.

Alas~

It really makes me worry about my father~

…

When everyone returned to the meditation room on the first floor, they saw Koizumi Hongzi standing in front of the mirror in the corner.

This mirror was previously used by Koizumi Hongzi to perform psychic skills, but the result was a complete failure.

At this moment, she was standing in front of the mirror, facing the mirror, wearing a red robe, motionless.

Alas~ the little girl started to be narcissistic again...

Qin Zhibo was a little speechless. He brought this pair of boys and girls, one was naughty + rotten, and the other was narcissistic + willful.

Not as obedient as Conan!

Qin Zhibo ignored Koizumi Hongzi and conducted his own investigation.

First of all, the most eye-catching investigation point is the investigation point on the neck of the blonde girl's body.

【Survey√】

[An unusual strangulation mark]

Fewer words mean bigger things.

Qin Zhibo leaned his head over and after a quick look, he discovered the problem.

This is a trace without the Yoshikawa Line.

The so-called "Yoshikawa Line" means that when someone strangles the neck, the victim will subconsciously use his hands to open the rope to give his throat room to breathe.

The traces produced by this struggle are the Yoshikawa Line.

The blonde girl's neck was a complete mark of strangulation, without any trace of struggle, and her expression was as calm as if she was asleep.

"Um……"

Qin Zhibo groaned, silently writing this down in his mind.

Next are trivial investigation points elsewhere in the room.

Hidden are the motor behind the bookcase, the motor remote control on the low cabinet, and the fallen A-shaped ladder in front of the skylight switch...

These are obviously props used to shape the secret room.

Instead, the murderer used Hirasaka's trick of pretending to be a ghost during the seance to make it reasonable for these props to appear at the murder scene.

This shows that the murderer should have known about the various techniques Hirasaka planned to use at the seance before the seance.

Otherwise, just relying on more than an hour after the seance ended, I would not have been able to come up with such a complicated method.

Coupled with the discovery of the purpose of the poster upstairs, Qin Zhibo already had a rough idea of ​​the method of creating a secret room.

Next comes the identity of the murderer and the evidence.

The murderer was obviously someone who might have known in advance about Hirasaka's techniques at the séance.

Among them, the doctor man is currently the most suspected.

He made it clear that this plan was planned by him and Hirasaka, and the purpose was to find the person who threatened them and killed the editor.

He had every chance to plan the crime in advance.

Secondly, the girl with short hair.

Judging from the information provided by Takagi Wataru, the short-haired girl was also one of the party participants who caused Yahara Huang's death.

Therefore, Hirasaka may have discussed these matters with her as well.

However, considering the short-haired girl's figure and physical strength, she may not be able to complete this highly difficult crime method.

Is there anyone else?

Qin Zhibo fell into deep thought again.

After a while, he still felt that the three recent murders should be analyzed together.

The first case was the death of the editor man half a month ago.

In this case, the murderer left the word "kira" in blood next to the body.

So the motive for the murder in this case was to avenge the death of Yahara Huang.

However, in the two cases that happened today, the blonde girl was strangled to death and Hirasaka was poisoned. There were no blood words or any other traces left next to them.

Generally, serial killers will not easily break the killing pattern they established at the beginning.

The murder of the blonde girl shows that although she was the first person to discover the body of the editor man, she was indeed not the murderer.

This shows that the bloody writing on Kira at the scene of the first murder was most likely left by the blonde girl.

Because the police did not disclose the clues about the blood letter, the real murderer quickly fled the scene after committing the crime. He did not know the existence of the blood letter before it was announced, so he did not add anything to the subsequent crime process.

And if the murderer’s motive was revenge, why did he kill the blonde girl?

The blonde girl has nothing to do with the party a year ago, so she should be innocent.

unless……

Qin Zhibo thought of something.

That is love.

The blonde girl likes someone here today. This has been concluded before.

If the so-called blood words were the names of other people left behind by the blonde girl to cover up the deceased, it would instantly make more sense.

Qin Zhibo remembered that he had encountered such a case before, and the first discoverer of the corpse added a death message to the deceased in order to cover up his lover.

I remember that the case was shot on location for a TV station for Okino Yoko's TV series, and Koizumi Anko was also present at the time.

Kira, what was it supposed to be like?

Qin Zhibo immediately used his fingers to write on the top of the round table, using the contrast of the velvet surface to just write.

First of all, exclude English, the most likely native language that Japanese people think of immediately before they die.

The next thing that remains is whether it should be Katakana or Hiragana.

Qin Zhibo understood everything with just two strokes on the table.

Hiragana is too complicated, while katakana only requires a few strokes.

Kira's katakana, キラ, only needs to be arranged vertically and compactly, and if one word is removed, it will become ミフ, which means three ships.

Among all the people present, only the yellow-haired man's surname was Mifune.

The reason why the blonde girl was killed was most likely because she discovered the death message of the editor man before his death, and protected him out of love.

But she took the initiative to find the yellow-haired man and confessed that she knew his secret, obviously ignoring the inner sensitivity of a murderer.

That's why she was killed.

Now that the murderer has been identified, there is still a lack of direct on-site evidence.

Although the words written in blood can be used as indirect evidence, after all, the time of the crime was far away from now. If the yellow-haired man has a strong psychological endurance and is determined to defend to the end, it will be in trouble.

Just when Qin Zhibo was thinking about where to find evidence, Koizumi Hongzi's cry suddenly sounded in the empty room.

"I know who the murderer is!"

"What?"

Everyone standing in front of the door was paying attention to the actions of the famous detective Qin Zhibo, especially the yellow-haired man himself who was the most nervous, but they did not expect that the girl in red robe in the corner next to him spoke first.

Koizumi Anko slowly turned around with a proud smile on her face.

"The murderer is Kira!"

"In other words, the murderer is a woman who calls herself Kira!"

When the fat otaku heard this, he was holding a witch figure on his phone, and his greasy fat face immediately climaxed, "Kira? Is it Kira!"

"Kira is really back! Hahaha..."

Others also showed expressions of disbelief. For a moment, the two forces of reason and superstition were struggling and entangled with each other in their brains.

Seeing that the direction of public opinion on the scene was gradually being distorted, Qin Zhibo could not turn a blind eye, otherwise it would be detrimental to his subsequent reasoning in the case.

"Sister, what are you talking about?"

Qin Zhibo walked to Koizumi Hongzi and said anxiously: "The murderer is obviously Mifune!"

Among the crowd, the yellow-haired man with the only surname "Mifune" trembled, and his eyes, which were a little relaxed a moment ago, suddenly became tense.

After killing someone, he thought about countless scenes that would be revealed, but he never expected that he would be pointed out by a famous detective in such a most casual way.

This kind of revelation without any psychological preparation is the scariest thing.

Upon hearing Qin Zhibo's refutation of his point of view, Koizumi Anko also added angrily: "This is the soul of Utakaura Akiko, who is my channel, and I personally asked her about it!"

After this explanation, Qin Zhibo glanced at the mirror next to her again, and then realized what she was doing standing in front of the mirror just now.

It turns out he is channeling...

This girl actually cheated!

The key to cheating is that the answer is wrong.

"ha……"

Qin Zhibo laughed out loud and shook his head, "The answer you get from channeling is not necessarily correct."

"Psychics are too easily swayed by human emotions, but reasoning is not..."

"Actually, the two deceased tonight, plus the editor who died half a month ago, there is no doubt that the murderer of the three cases is Mr. Mifune."

Qin Zhibo once again solemnly released information about the murderer.

At this moment, everyone around him immediately gave up their position exclusively for the murderer to the yellow-haired man.

The yellow-haired man's eyes widened, his pupils suddenly tightened, and the cold sweat on his forehead had been pouring out uncontrollably since just now, and now it has accumulated enough to flow down his cheeks.

Seeing that the direction of public opinion that had been deflected by Koizumi Hongzi was being pulled back, Qin Zhibo began to reason.

"Actually, the two murder methods used to create secret rooms today were very simple."

"You first go to Mr. Hirasaka's room on the second floor, kill Mr. Hirasaka with poisoned wine, and take the lock between the room key and the meditation on the first floor."

"Then you came to the meditation room on the first floor and killed Miss Utagura Akiko, who had made an appointment to meet."

"Next, you lock the door of the meditation room from the inside, then make the posters here into several paper tubes of different heights, and tie the paper tubes together to form a ladder for you to escape from this skylight. "

Qin Zhibo turned and pointed to the three-meter-high skylight.

"As for closing the skylight, you used the motor and the A-type ladder here to create a mechanism. As long as you control the motor to turn on outside the skylight, you can close the skylight."

"The motor and A-shaped ladder here remain the same. When Kaito comes, I will let him demonstrate the technique again..."

Kaitou Kidd demonstrated this kind of technique that requires some operations, which is very relevant to professionals.

"Then, you return to the Hirasaka room on the second floor, use the paper tube made from the poster to return the key to the drawer through the ventilation window above the door, and then tear the poster into pieces, along with the crime tools and Ms. Akiko's mobile phone. Throw it back into the room."

"Of course, before sending the phone back, you have already sent a group text message. Everyone will receive the text message and go to the meditation room below to gather."

"You asked me to break the glass with a vase and unlock the lock from the inside without even thinking about it. That made me a little suspicious."

"Why can you tell at a glance that the door is locked from the inside instead of directly from the door handle?"

"Actually, you were in a hurry to enter the meditation period, so you took advantage of the chaos to put the motor remote control back to the scene, and accidentally made a slip of the tongue..."

Qin Zhibo said as he walked to the short cabinet and picked up the motor remote control placed on it with his right hand wearing a white glove.

"If I remember correctly, only Mr. Hirasaka himself has touched this remote control..."

"But now, I bet your fingerprints are still on it."
