Conan's grammatical investigator

"Hunter of Terror? What is this?"

"A very terrifying creature. According to the records in the magic book, it looks like a big snake flying in the sky. It is a servant of the faceless god. In most cases, it will only appear under the call of the god."

Koizumi Hongzi pressed her finger against the page of the old magic guide book, and said word by word: "If it is a summon that has nothing to do with a god, you must sacrifice blood and living things to it to please it, so as to increase the probability of a successful summon... "

"In short, this magic circle is very evil. Where did you find it?"

"where are you now……"

Qin Zhibo hung up the phone, lost in his mind.

The appearance of the Horror Hunter's summoning magic circle here means that someone has used it.

Then the monster that the elder brother of the owner of the villa encountered before is likely to be this kind of monster...

Qin Zhibo stood up from the ground, staring at the bird house on the big tree in the backyard.

With flickering eyes, some pictures appeared in Qin Zhibo's mind.

He seemed to see the slain creatures in the bird house, the body of the little bird chopped into pieces, blood oozing from the variegated feathers.

The first call should be the bird in the bird house, so that my brother saw the "monster" at the window.

Second call...

Qin Zhibo withdrew his thoughts in time and stopped thinking about what had happened.

His gaze returned to the bottom row of the bookshelf, and he reached out to move out a set of seven thick encyclopedias.

Before returning the disordered book numbers, Qin Zhibo saw an investigation point hidden on the wall behind the books.

【Topographic Survey√】

【This is a secret passage】

Qin Zhibo: "!"

He quickly removed all the books on the side and the previous row, and saw the complete passageway.

It's a trapdoor built into the wall.

Normally, the trapdoor is covered by bookshelves and books, and it is located in the corner of the wall, so it cannot be seen from the outside.

The trap door can be pushed aside, revealing a dark passage inside.

……

On the other side, Conan was holding his chin, thinking about the room key on the coffee table.

With Qin Zhibo's acquiescence, Conan checked the doors and windows of the entire room as soon as he could inspect the site, and they were all locked.

The deceased died in the room, and the doors and windows were locked, and the murderer was not hidden in the room.

This is a typical closed room murder case.

The key to a murder case in a secret room is to decipher how the murderer got out of the room.

Anyway, Conan, like Qin Zhibo, would never believe suicide.

Judging from practical experience, the seemingly suicide cases that Conan encountered were actually not suicides...

Conan glanced at the corpse hanging under the chandelier again, and the chic key ring around his waist.

If there is that retractable key ring, the murderer can easily arrange the secret room, which is even easier to solve than all the secret room cases encountered before.

But the problem is that the room key happened to be far away from the key ring.

"..."

Conan tried his best to restrain his eyes from looking in Qin Zhibo's direction, so as not to disturb his reasoning rhythm.

Because the direction of Qin Zhibo's investigation often means the "correct answer", and the police haven't arrived yet, if he reads the answer, it is not his own reasoning.

It's like you obviously want to rely on your own efforts to complete an assignment independently, but the bad friend next to you holds a standard answer in his hand and keeps dangling in front of you.

He even kept whispering devilish whispers.

"Come on~"

"Copy me~"

In order not to be tempted and influenced by the answer, you can only narrow your vision as much as possible, and don't pay attention to the bad friend and the answer in his hand.

But within the limited field of vision, Conan really couldn't see any more clues.

No way, Conan had to turn his gaze to the bookshelf behind the sofa.

Bookshelves are often the focus of Qin Zhibo's investigations.

Conan still remembers the first time he met Qin Zhibo, and it was also the first case they cooperated with. Qin Zhibo unexpectedly stood in front of the bookshelf to investigate.

To this day, Conan has no idea why he investigated the bookshelf at the time.

However, Qin Zhibo was not standing in front of the bookshelf at the moment.

Not just the bookshelves, but the rest of the room.

Sensing that something was wrong, Conan quickly looked around, but found that the man with a height of 185 was no longer in the huge room.

how can that be!

Conan immediately ran out of the room and asked Hondo Eisuke and others who were standing at the door of the room.

"Did uncle leave the room just now?"

"No? I didn't see..."

Eisuke Hondo and Sonoko shook their heads, and Mao Lilan and the band, who had returned from calling the police, also came back at this time.

"Conan, what's wrong?"

"It's Uncle Qin, who suddenly disappeared in the room!"

"disappear?"

The three members of the band showed shocked expressions, but one of them was more vivid than the other two in terms of expression and inner drama.

Could it be that the secret passage has already been discovered by him!
no!I'm going to go back and have a look!
The crew cut man among the three was about to turn around and go upstairs when he saw a figure walking down the stairs.

It was Qin Zhibo!
Seeing Qin Zhibo appearing from upstairs, everyone showed expressions of surprise, especially Conan.

"Mr. Qin, when did you get upstairs? Why didn't I see it?"

Hondo Eisuke, who had been standing at the door waiting, asked incomprehensibly.

Qin Zhibo smiled, looked at the crew-haired man in the band, and said leisurely, "I'm going to ask Mr. Kuramoto..."

"No, it should be the murderer who killed Miss Lunzi!"

After the words fell, everyone gave up a C position exclusively for the murderer for the flat-headed man.

Conan's mouth was wide open.

So fast!
I haven't started yet!You are done!

Conan's brain suddenly realized something, and hurried back to the bookshelf in the room.

I saw several stacks of books stacked in the corner of the bookshelf, and the corresponding bookshelf was not only empty, but also revealed a secret passage on the wall behind the bookshelf.

Seeing this secret passage, Conan suddenly understood everything.

That's how it turned out, I finally understood why Qin Zhibo wanted to investigate the bookshelves in the first place.

Strictly speaking, the case of Sowa House was considered a murder case in a secret room.

Qin Zhibo's purpose is to find out if there is a secret passage behind the bookshelf!
Under the circumstances at that time, if one did not have rich experience in handling cases, it was impossible to immediately think of finding secret passages.

This shows that Qin Zhibo's investigation of the case has formed a logical chain and operation process as precise as a software program, and he will execute it every time he encounters a similar case.

In fact, this kind of fixed thinking mode is shared by most people who are engaged in the police profession.

For example, police officer Mumu asked about the information of the deceased, the alibi of the suspect, and looked for "brothers" around... This set of standardized procedures is essential for every case.

It's just that Qin Zhibo's standard procedure is more complicated and advanced than Mu Mu's.

Perhaps in his brain, as long as he encounters a secret room case, he has already listed method 1, method 2, method 3, and method 4...

Then, through the on-site conditions, confirm the operational feasibility of each technique one by one.

Sherlock Holmes once said that when all false options are eliminated, the remaining answer, no matter how absurd, is the truth.

Using this rigorous reasoning logic, coupled with Qin Zhibo's terrifying observation ability, the investigation speed is naturally faster than that of himself who is completely on the spot.

This is the difference in experience!
At this moment, Conan more clearly realized the gap between himself and Qin Zhibo.

This gap can only be bridged with time and a large number of cases.There is also a 20-year age difference between the two, except for talent and aging, those different parts.

But fortunately, in the land of Tokyo, cases are never lacking.

Conan has full confidence in this.

In other words, as long as I reach Qin Zhibo's age, I can also have such reasoning ability?

Thinking of this, Conan's heart was greatly encouraged, and his waist straightened up.

……

Outside the room, although the crew-cut man already felt something bad in his heart, he was still lucky.

He quickly defended: "You, what are you talking about? How could I be the murderer?"

"When you found the body, I was also outside the room!"

"I found the body like everyone else, so why do you only suspect me! Isn't Xiang Hechun also suspect?"

The flat-headed man became more and more agitated, referred to as "anxious", and began to pour dirty water on his companions.

The man with glasses and the wave woman were stunned, they didn't recognize the companion in front of them.

"Do not……"

"I'm not doubting you, but I'm sure you are the murderer."

Qin Zhibo smiled slightly, and slowly revealed the secret, "Actually, there is a secret passage in the room at the scene of the crime, which directly connects to a bedroom on the third floor."

"Secret passage?" Everyone wondered.

At this time, Conan came out of the room, "Uncle Qin is right, there is an upward passage behind the bookshelf in the room..."

Qin Zhibo glanced at Conan, this kid was quite fast.

Qin Zhibo continued: "The wallet in that bedroom contains your driver's license, which proves that it is your room."

"After killing Miss Lunzi, you returned to the room on the third floor through the secret passage, and then came to the second floor as if nothing had happened."

"But you ignored the order of the books on the bookshelf in your haste, and this revealed your flaws."

Conan was still a little surprised when he heard this.

Among the hundreds of books on the bookshelf, it is terrifying to see where the book numbers are not in the right order at a glance.

If the reasoning ability can be caught up with time and experience, how can this observation ability be improved?

It would be great if Dr. Ali could invent the kind of high-tech glasses that immediately mark out doubts at a glance...

The flat-headed man saw that his tricks were exposed, but he still refused to give up in his heart.

He clenched his hands tightly, and cold sweat broke out on his forehead, as if his defense had been broken, but he still yelled at Qin Zhibo.

"It's useless for you to tell me this! I don't even know what secret passage is in my room!"

"What evidence do you have to prove that I killed Lunzi!"

Seeing that the man with the flat head wanted to defend to the end, Qin Zhibo also entered the stage of "seeking the hammer to get the hammer".

"When you found the corpse just now, you had to step forward to help put the corpse down. Apart from acting, there should be other purposes, right?"

"Because the rope you used to strangle people has your fingerprints on it."

Hearing this, the flat-headed man's body trembled suddenly, and cold sweat dripped from his forehead.

"In this crime, you should not have planned the killing plan in advance, but killed it impulsively."

"You killed the deceased on impulse. Not only did you not wear gloves, but because you were worried that you would be seen, you checked the reaction of everyone in the backyard from the sealed window..."

Hondo Eisuke suddenly recalled the peeping eyes he saw in the backyard, and said in surprise: "So it was him at that time!"

"That's right." Qin Zhibo nodded, "As for why the sealed window can be opened, everyone will know what's going on when they enter the secret passage."

Qin Zhibo turned his head to look at the flat-headed man again, "But you never expected that my identity is a detective, and I quickly protected the scene after the case happened, without giving you a chance to touch the rope..."

"Now just wait for the police to come and check the fingerprints on the rope, and it will prove that you are the murderer."

Qin Zhibo judged that the flat-headed man decided to kill on the spur of the moment, and there was another reason.

Even when Lunzi was yelling at everyone in the band, their facial expressions were well managed.

Under the ironclad evidence, the flat-headed man's psychological defense finally collapsed, and he revealed his motive for killing.

It turned out that he and Rinko had been arguing about how to play the guitar, but after the last quarrel, he practiced alone for a long time.

But today when he went to Lunzi to test the results, Lunzi still said that he couldn't play well, and insulted his favorite guitarist by the way.

Just like that, when he regained his senses, Lunzi died with a rope wrapped around his neck.

After hearing the reason for the murder, Qin Zhibo shook his head helplessly.

Another outrageous reason to kill.

But who cares, his case has been solved.

[Congratulations on completing the side mission! 】

[Mission Rating: Grade A]

[Get 500 general skill proficiency]

【Get 150 Social Credit】

[Rating reward: 500 general skill proficiency]

Since the case was solved before the police arrived, the proficiency reward was doubled for a direct A-level evaluation.

Although this reward is a bit small compared to the largest mainline task that will be possible to complete soon, it is at least better than nothing.

……

Half an hour later, the police from Gunma County arrived late.

Qin Zhibo was still surprised to see that it was not the police officer Mu Mu who came, but the mountain village man with pouty lips.

After careful questioning, I found out that this location is at the junction of Tokyo and Gunma. This villa happens to be under the jurisdiction of Gunma County, and the Suzuki family villa not far away belongs to the Tokyo area.

This time Mori Kogoro was not around, so Qin Zhibo could only personally explain the ins and outs of the case to the rookie policeman.

When explaining the secret way, Qin Zhibo explained to everyone the mystery of why the crucified window could be opened.

It turned out that in order to expand the space of the secret passage on the basis of the original villa, a false window was built in the library and nailed from the inside.

Inside the secret passage, there are half windows corresponding to the real windows outside the building.

"Hondo Eisuke and I saw only half of the windows open in the backyard. In fact, the crew-haired man was using the half window in the secret passage to observe the backyard..."

While talking, Qin Zhibo opened the half window next to the wall, and demonstrated for the mountain village in the narrow secret passage.

Suddenly, Qin Zhibo stared out of the window and was stunned.

I saw a dark man standing there under the big tree where the bird house was built, staring straight at him.
