Conan's grammatical investigator

Chapter 1399: The Dark Mysterious Train (Technique)

Carriage 6, Room D.

"I finished looking, but I didn't find that person..."

The three little ones returned the phone to Sera Masumi, all of them were in very low spirits.

Because after repeated identification by the three little ones, they did not find any passenger whose back was the same as the "criminal" who escaped at that time.

"is it?"

Shiliang took the phone and could only smile and comfort the three little ones, "It doesn't matter, even if we can't recognize it, Detective Maori will definitely be able to find out who the murderer is!"

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

After saying that, Shira left in a hurry.

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

Mao Lilan saw it and asked hurriedly: "Xiao Ai, where are you going?"

"I'm going to the bathroom and take some medicine..."

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

Mao Lilan wanted to follow him worriedly, but Suzuki Sonoko beside her 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's okay, just sit here and wait for a while. Isn't the murderer suspected in car 8? This means that the other cars are absolutely safe."

After Sonoko's explanation, Mao Lilan felt a little relieved and did not chase after her.

……

Car No. 8.

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

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

"What are you talking about? Mr. Noto..."

"I just came out to check out the quarrel in the corridor. How did I become the murderer?"

"And the suspicious figure 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 chuckled.

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

"As for what method you used, I think I can tell by checking the items you carry with you."

"What do you say, Detective Maori?"

Qin Zhibo left the decision-making power to Maori Kogoro. After all, he couldn't stand out too much and arouse Conan's suspicion.

Since Qin Zhibo used the simplest method of elimination, which is also the correct application of the method of elimination, 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?"

"Forehead……"

Anton glanced at the suspicious looks of the crowd, knowing that if he refused now he would be in a more passive situation, so he could only nod and accept.

"All right……"

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

"What is that?" asked Kogoro Mouri, pointing at the thing.

"It's an authenticated painting that I plan to return to the client in Nagoya."

"Can I open it and take a look?"

"okay."

After getting consent, Kogoro Maori opened the package and took out a painting with a golden 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 it 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 down his temples.

"…This is a way to deceive the appraiser. Using more expensive decorations will make it easier for the appraiser to be careless…"

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

"Well, after all, I am a professional..."

Conan, who was sitting in a low position, was listening to the conversation between Noto and Anton, his little face looking thoughtful.

Although Anton's explanation sounds reasonable at first glance, if this picture frame is really pure gold, it is worth at least 10 billion yen.

In order to make a fake look real, you decorate it with a 10 billion yen pure gold frame?

Moreover, if even the frame is worth 10 billion, then the value of the painting itself should be even greater. Most appraisers would actually conduct a more careful appraisal.

Wasn't the frame 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 while Kogoro Mouri was looking at the painting without paying attention, he put his little hand directly on the painting.

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

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

Fortunately, this painting is a fake, otherwise if the pressing just now left a mark that cannot be cleaned off, I would not be able to compensate the other party even if I paid all of Conan’s child support to him.

Before Maori Kogoro could catch Conan and teach him a lesson, Conan quickly pointed at the painting and shouted, "The painting feels weird when pressed down, as if there is something stuck in it!"

"what?"

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

However, looking at the combined thickness of the painting and the frame, the space in the middle should feel hollow.

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

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

However, Kogoro Mori was not so dull, and from his uneasy reaction, he could tell that there must be some other hidden story.

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

"dismantle……"

Before Anton could agree, Kogoro Mori removed the back panel of the pure gold frame.

The space between the back panel and the painting is filled with a glass mirror.

But there is not just one mirror, but three.

"Mirror?"

"Mr. Anton, please explain what is going on?"

"This……"

Seeing that the important tools used in the crime had been 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 was a fake?"

"…Even though it's a fake, it has to be delivered to the customer intact…"

"Is that so?" Kogoro Mori looked skeptical, but he couldn't find a better reason to question for the moment.

However, when Conan looked at the three mirrors of the same size, then turned his head to look at the door behind him, his mind suddenly exploded.

I understand!
That's it!

Conan showed a confident smile on his face, and although he seemed to be obedient and took the initiative to leave the room, he actually came to the door, pointed at it and shouted.

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

"what?"

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

These three mirrors have no frames and are of the same specifications. There is adhesive on the back, so they can be easily put together if there is a flat surface.

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

Suddenly, Kogoro Mori also understood.

"I see!"

"You put these three mirrors together and stuck 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 himself in the mirror."

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

"In order to avoid noticing that the house number reflected in the mirror was wrong, you even covered it with red paint so that the house number could not be seen..."

"The conductor said he saw a figure in what is probably Room A, which also proves 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!"

Kogoro Maori put his hands in his pockets with a confident smile on his face.

Even Conan smiled with satisfaction at this cool and handsome reasoning.

This time, I only gave him a little hint, but he was able to say so much in one breath. The uncle has made progress~
The same happened in the last "Aphrodite" incident, where Kogoro Mouri found the real murderer before himself.

That time, even Conan had to admit that his number of layers was not as good as Kogoro Mouri's.

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 already entered Mr. Murohashi's room when the conductor was going from Room A to Room E."

"But the conductor didn't notice that the door of compartment C was open, did he?"

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

This question stumped Kogoro Mouri. His expression, which had been very handsome and confident just a second ago, suddenly turned into a frustrated and cute look.

"Um... I think 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 can this be?!"

Anton's voice got louder. "The conductor even saw the figure in the corridor. If I had walked directly into the corridor, I would have been discovered immediately!"

"Um, well..."

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

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

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

Conan opened the cover of his watch, intending to give Kogoro Mouri a quick death.

But at this moment, a hand gently patted his back.

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

The passenger named Noto handed him a thin rope and said with a smile: "Little boy, this rope is for you to play with."

Give me the rope to play with?

You really treat me like a child. What's so fun about this?

Conan took the rope doubtfully, and just as he was puzzled, he suddenly thought that this thing could be used to demonstrate case methods.

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

Pulling the rope left and right causes the door to swing left and right as well.

"Hey~ this is really fun!"

“It’s so fun~!”

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

Just as I was about to start scolding him, I suddenly remembered something.

"Yup!"

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

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

"Mr. Anton, you designed a fake reasoning puzzle in advance to make Mr. Murohashi exchange rooms with my daughter and her friends, making it easier for you to carry out your murder plan."

"Before the train entered the tunnel, you discussed the mystery with Mr. Murohashi over the phone as a 'criminal'."

"After the train entered the tunnel, you said the signal was bad and you wanted to go directly to his room to discuss it."

"At this time, the conductor has been attracted to Mr. Noto in Room A because of the trap you set earlier. The open door just happens to cover up your movement to leave your room."

"After you finished killing people in Room B, the conductor was called to the other side of the car by Miss Izumi who complained about strange noises in the room."

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

"am I right?"

Kogoro Mouri showed a confident expression, this time he was completely sure of what he wanted.

Anton, who was hit in the vitals, turned pale and sweat broke out on his face.

But he still has to make a final struggle.

"What about the secret room in Room B?"

"Wasn't the door of Room B locked with a security chain? If I killed someone, how did I get away?"

This question stumped Kogoro Mouri again, and he looked embarrassed.

Conan at the door was also stunned. He was so busy thinking about how to commit the crime that he forgot to think about how to use the locked room.

However, now that the murderer has been identified, it is only a matter of time before the method is discovered.

Just as Conan turned around to look for evidence, a loud voice suddenly sounded behind him.

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

"What did you say?"

Hearing this, Kogoro Mori suddenly became excited.

"I see! You have also modified the anti-theft chain of Room B in advance!"

"As long as the number of anti-theft chains is increased, you can hang them up even if you are standing outside the door!"

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

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

"If this guy hadn't done what he did five years ago, I wouldn't have killed him!"
