The Grammatical Investigator in Conan

Carriage No. 6, Room D.

"I've checked, but I didn't find that person..."

The three kids returned the phone to Sera Masumi, all in a very low mood.

Because after repeated identification by the three kids, they didn't find any passenger whose back was the same as the "criminal" who escaped at that time.

"Really?"

Sera took the phone and could only smile and comfort the three kids, "It doesn't matter, even if you can't recognize it, Detective Maori will definitely find out who the murderer is!"

"That's it for now, I'll go back and tell Mr. Maori and the others..."

After that, Sera left in a hurry.

After Sera Masumi left, Haibara Ai also jumped off her seat and walked towards the door.

When Maori Ran saw it, she hurriedly asked, "Xiao Ai, where are you going?"

"I'm going to the toilet and take medicine..."

Haila Ai's voice was very cold, and she opened the door and left after she finished speaking.

Mao Lilan wanted to follow him worriedly, but Suzuki Sonoko beside him hugged her shoulders and said calmly: "That child is different from ordinary kids. Even if you follow him now, you will only be hated."

"But..."

"It doesn't matter. Just sit here and wait for a while. Isn't the suspect of the murderer in car No. 8? This means that other cars are absolutely safe."

After Sonoko explained, Mao Lilan felt a little relieved and did not chase him out.

...

Car No. 8.

"So the murderer can only be you, Mr. Anton."

Hearing Qin Zhibo's verdict, Anton Yu's body trembled violently, with an incredible expression on his face.

"You, what are you talking about? Mr. Noto..."

"I just came out to check the quarrel in the corridor. How can I be the murderer?"

"And the suspicious figure that the conductor saw at the time appeared in your room..."

Anton Yu continued to quibble and even framed the other party.

But Qin Zhibo was not in a hurry and smiled softly.

"Hmph, if you hadn't mentioned that figure, I would have forgotten about it. I guess you designed that figure, too?"

"As for the method, I think we can find out by checking the items you carry with you."

"What do you think, Detective Maori?"

Qin Zhibo handed the decision to Maori Kogoro. After all, he couldn't be too outstanding and arouse Conan's suspicion.

Since Qin Zhibo used the simplest elimination method, which was also the correct use of the elimination method, Maori Kogoro also understood the logic and turned to look at Anton Yu.

"Mr. Anton, can we go into your room and check it out?"

"Uh..."

Anton scanned the suspicious eyes of the crowd and knew that if he refused at this time, his situation would be more passive, so he could only nod and accept.

"Okay..."

Anton led everyone to his room. There was only a huge rectangular package in the clean and tidy room, which was placed horizontally on the sofa seat like a blackboard.

"What is that?" Maori Kogoro pointed at the thing and asked.

"It's the painting I plan to send to Nagoya to return to the client."

"Can I open it and take a look?"

"Okay."

After getting his consent, Maori Kogoro opened the package and took out a painting with a gold frame.

"This painting is quite heavy..."

"Well, after all, this is a frame made of pure gold."

At this time, Qin Zhibo, who was standing at the door, suddenly said: "Mr. Anton, I remember you said before that this painting is a fake, right?"

"Yeah." Anton nodded, not understanding what he meant.

"But why would a fake painting be decorated with a pure gold frame? Isn't this a bit unreasonable?"

Hearing this, Anton was stunned, and two drops of cold sweat flowed from his temples.

"...This is a means to deceive the appraiser. Using more expensive decorations will easily make the appraiser take it lightly..."

"So you didn't let your guard down?" Qin Zhibo continued to ask with a smile.

"Well, after all, I'm a professional..."

Conan, who was standing low, listened to the conversation between Noto and Anton, and his face looked thoughtful.

Although Anton's explanation sounded reasonable at first, if this picture frame was really made of pure gold, it would be worth at least 1 billion yen.

In order to make a fake look real, it was decorated with a 1 billion yen pure gold picture frame?

And if the picture frame is worth 1 billion, then the value of the painting itself should be greater, and most appraisers would appraise it more carefully.

Could it be that the picture frame is not made of pure gold?

The reason why it is said to be pure gold is to cover up its unreasonable weight?

Thinking of this, Conan ran into the room and took advantage of the fact that Maori Kogoro, who was looking at the painting, was not paying attention, and directly pressed his little hand on the painting.

This little action was seen by Maori Kogoro, who was immediately shocked.

"Ouch! What are you doing, little brat?"

Fortunately, this painting is a fake, otherwise if the pressing just now leaves a mark that cannot be cleaned, even if all Conan's child support is paid to the other party, it cannot be compensated.

Before Maori Kogoro caught Conan and taught him a lesson, Conan quickly pointed at the painting and shouted: "The painting feels weird when pressed, as if there is something stuck inside!"

"What?"

Mauri Kogoro showed a puzzled look, turned around and gently pressed the surface of the painting with his fingers. Sure enough, it was not soft, as if there was something hard under the painting.

However, judging from the thickness of the painting and the frame, the gap in the middle should feel hollow.

Maori Kogoro pointed at the painting and asked Anton behind him: "Mr. Anton, is there anything else in this painting?"

"Ah?" Anton stammered, "It's to protect the painting..."

However, Maori Kogoro was not so slow, and from his uneasy reaction, he could tell that there must be something else.

"Do you mind if I open it and take a look?"

"Open it..."

Before Anton agreed, Maori Kogoro opened the back plate of the pure gold frame.

In the gap between the back plate and the painting, there was a glass mirror.

And there were not just one mirror, but three.

"Mirror?"

"Mr. Anton, please explain what's going on?"

"This..."

Seeing that the important tool for the crime was discovered, Anton could only continue to be stubborn, "I just said that it was to protect the painting from being crushed..."

"But didn't you just say that this painting is a fake?"

"...Although it is a fake, it must be delivered to the customer intact..."

"Is that so?"

Mouri Kogoro looked doubtful, but he couldn't find a better reason to question it for a while.

But Conan looked at the three mirrors of the same size, turned his head and glanced at the door behind him, and his mind exploded instantly.

I understand!

So that's it!

Conan showed a confident smile at the corner of his mouth, but he seemed to be obedient and took the initiative to leave the room, but in fact he came to the door and pointed at the door and shouted.

"How interesting! The area of ​​this door seems to be exactly the same as the area of ​​the three mirrors combined!"

"What?"

Mouri Kogoro suddenly turned around and looked at the door Conan pointed at, and then looked at the three mirrors on the table.

These three mirrors have no frame and the same specifications. There is glue on the back. If there is a flat surface, they can be easily put together.

There is also a red paint block in the middle of one of the mirrors.

Suddenly, Maori Kogoro also understood.

"I know!"

"You put these three mirrors together and pasted them on the inside of the door to block yourself from walking out of Room B after killing someone!"

"The suspicious figure the conductor saw at that time was actually the person in the mirror that the conductor saw."

"Because the train was passing through a tunnel at the time and the lights in the corridor were dim, it was inevitable that he would make a mistake."

"In order to avoid being discovered that the house number reflected in the mirror was wrong, you also deliberately covered it with red paint at this position so that the house number could not be reflected..."

"The conductor said that he saw a figure in the position of Room A, which can also prove that the mirror door is in Room C."

"Because the image reflected in the mirror is twice the distance between the real object and the mirror, and the middle position between Room E and Room A is exactly Room C..."

"That is your room, Mr. Anton!"

Mouri Kogoro put his hands in his pockets, with a confident smile on his lips.

This cool and handsome reasoning made even Conan smile with relief.

This time, I only gave him a little hint, but he was able to say so much in one breath. Uncle has improved~

The last "Aphrodite" incident was also like this. Maori Kogoro found the real murderer before me.

That time, even Conan had to admit that his level was not as good as Maori Kogoro.

Of course, they both lost to Qin Zhibo who stood directly in the atmosphere.

"But if that's the case, how did I open this door?"

"According to what you said about the crime, Mr. Maori, I had entered Mr. Murohashi's room when the conductor went from Room A to Room E."

"But the conductor didn't notice that the door of Room C was open at that time, didn't he?"

Anton turned his head to look at the conductor, and the conductor nodded in agreement, indicating that he did not notice that the door of Room C was open at that time.

This question stumped Maori Kogoro, and his expression, which was very handsome and confident in the last second, suddenly turned into a frustrated and cute look.

"Uh... it should be that you walked out of the room after killing someone, came to the corridor and opened the door of Room C, and the conductor just didn't see it..."

"How is this possible?!"

Anton's voice became louder, "The conductor even saw the figure in the corridor. If I came directly to the corridor, I would definitely be discovered immediately!"

"Uh, this..."

Seeing that Maori Kogoro couldn't explain himself, Conan slapped his forehead helplessly.

I really overestimated him just now. He even forgot the most common method...

I thought I could save an anesthetic needle this time, but there is no way.

Conan opened the watch cover and planned to give Maori Kogoro a quick death.

But at this time, a palm gently patted his back.

This scared Conan, and he quickly closed the watch cover and looked back.

I saw the passenger named "Noto" handed him a thin rope and said with a smile: "Little friend, this rope is for you to play with."

The rope is given to me to play with?

You really treat me as a child. What's there to play with?

Conan took the rope with doubts. Just when he was puzzled, he suddenly thought that this thing could be used to demonstrate the method of solving a case.

So, he put the rope directly on the door handle, and then grabbed one end of the rope with his left and right hands and pulled it left and right.

The rope was pulled left and right, causing the door to swing left and right.

"Hey~ This is really fun!"

"It's really fun~!"

Mouri Kogoro was upset because he couldn't answer the question. Suddenly he turned around and saw Conan playing with a door. He was immediately furious.

Just when he was about to scold him, he suddenly thought of something.

"That's right!"

"You just need to use a rope, fishing line or something to tie the door handle of Room C, and then pass it through the railing of the corridor window. Even if you are in Room B, you can open the door of Room C with just a pull."

"In other words, your complete crime process is like this..."

"Mr. Anton, you designed a false reasoning puzzle in advance, so that Mr. Murohashi and my daughter would exchange rooms, which would facilitate your murder plan."

"Before the train was about to enter the tunnel, you discussed the reasoning puzzle with Mr. Murohashi on the phone as a "criminal."

"After the train entered the tunnel, you said that the signal was not good and you wanted to go directly to his room. Discuss."

"At this time, the conductor has been attracted to Mr. Noto in Room A because of the trap you set before, and the open door can just cover up your action of leaving your room."

"After you kill people in Room B, the conductor is called to the other side of the carriage by Miss Deba who complains about the strange noise in the room."

"At this time, you can open the door of Room C by the method I just mentioned, use the mirror behind the door to cover up your whereabouts, and at the same time, you can put the blame on Mr. Noto in Room A."

"Am I right?"

Mouri Kogoro showed a confident expression, this time he was completely confident.

And Anton, who was hit by the key point, was pale and sweaty.

But he still had to make a final struggle.

"What's the matter with the secret room in Room B?"

"Wasn't the door of Room B equipped with an anti-theft chain at that time? If I killed someone, how did I leave?"

This question stumped Maori Kogoro again, revealing an embarrassed expression.

Conan at the door was also stunned. He was busy thinking about the method of committing the crime and forgot to think about the method of the secret room.

However, since the murderer has been locked, it is only a matter of time to find this method.

Just when Conan turned around to find evidence, a loud voice suddenly sounded behind him.

"Actually, I was a little confused just now. Why are the anti-theft chains in other rooms composed of 5 iron rings, while the number of anti-theft chain iron rings scattered at the door of Room B is 6..."

"What did you say?"

Hearing this, Maori Kogoro also became alert.

"I know! The anti-theft chain of Room B has also been modified in advance by you!"

"As long as the number of anti-theft chains is longer, you can hang the anti-theft chains even if you stand outside the door!"

The breakthrough of this last key point is like the last straw that broke the camel's back, knocking Anton down completely.

"It's all that guy's fault!"

"If this guy hadn't done that five years ago, I wouldn't have killed him at all!"
