The three children returned the mobile phone to Sera Masumi, and they were all in a very low mood.
Because after repeated identification by the three little ones, no passenger's back was found to be the same as the "prisoner" who escaped at that time.
"Yeah?"
Seriang took the phone and could only smile and comfort the three little ones, "It doesn't matter, even if you can't recognize it, Detective Maori will definitely be able to find out who the murderer is!"
"Then let's do this for now. I'll go back and tell Mr. Maoli and them..."
After saying that, Seriang 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 quickly: "Xiao Ai, where are you going?"
"I'm going to the toilet and taking some medicine..."
Hui Yuan Ai's voice was very cold, and after speaking, he opened the door and left.
Mao Lilan wanted to follow him worriedly, but Suzuki Sonoko on the side hugged her shoulders and said calmly: "That child is different from ordinary brats. 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 murder suspect in the No. 8 carriage? This means that the other carriages are absolutely safe."
After Yuanzi explained this, Mao Lilan felt a little more relieved and did not chase her out.
…
Car No. 8.
"So the murderer can only be you, Mr. Anton."
Upon hearing Qin Zhibo's verdict, An Dongyu's body trembled violently, with an incredible expression on his face.
"W-what are you talking about? Mr. Noto..."
"I just came out to check on the quarrel in the corridor. How could I be the murderer?"
"And the suspicious figure the conductor saw at that time appeared in the location of your room..."
An Dongyu continued to quibble, and even framed the other party.
But Qin Zhibo was not in a hurry and chuckled softly.
"Hmph, if you didn't tell me that I forgot about that figure, you must have designed that figure too, right?"
"As for what method to use, I think you just need to check the items you carry with you."
"What do you think? Detective Mori?"
Qin Zhibo left the decision-making power to Mouri Kogoro. After all, he couldn't perform too well and arouse Conan's suspicion.
Since Qin Zhibo used the simplest elimination method and it was also the correct use of the elimination method, Mouri Kogoro also understood the logic and turned to look at Anton Yu.
"Mr. Anton, can we go in and check your room?"
"Forehead……"
Anton glanced at everyone's suspicious eyes, knowing that if he refused at this time, he would be in a more passive position, so he could only nod and accept.
"All right……"
Anton led everyone to his room. There was only a huge rectangular package in the clean and tidy room, lying across the sofa seat like a blackboard.
"What is that?" Mouri Kogoro asked, pointing at the thing.
"It's an appraisal painting that I plan to send to Nagoya to return to the client."
"Can I open it and take a look?"
"Well, okay."
After receiving the consent, Mouri Kogoro opened the package and took out a painting in 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, confused.
"But why is a fake painting decorated with a pure gold frame? Isn't this a little unreasonable?"
Hearing this, Anton's expression was stunned, and two drops of cold sweat flowed from his temples.
"...This is a way to deceive the appraiser. Using more expensive decorations can easily make the appraiser take it lightly..."
"So you didn't let down your guard?" Qin Zhibo continued to ask with a smile.
"Well, after all, I am a professional..."
The short Conan was listening to the conversation between Noto and Anton, with a thoughtful look on his face.
Although Anton's explanation sounds reasonable at first, if this picture frame is really pure gold, it would be worth at least 1 billion yen.
To make a fake look real, decorate it with a 1 billion yen solid gold frame?
Moreover, even the frame is worth 1 billion, so the value of the painting itself should be even greater, and most appraisers will conduct appraisals more carefully.
Isn't that picture frame 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 raised his legs and ran into the room. While Kogoro Mori, who was looking at the painting, wasn't paying attention, he directly pressed his little hand on the painting.
This small movement was seen by Mouri Kogoro and he was immediately shocked.
"Ouch! What are you doing, little brat?"
Fortunately, this painting is a fake. Otherwise, if the touch just now left traces that cannot be cleaned, even if Conan's child support is paid to the other party, he will not be able to afford it.
Before Kogoro Mouri could catch Conan and teach him a lesson, Conan quickly pointed at the painting and shouted: "The painting feels weird when you press it down, as if there is something stuck in it!"
"What?"
Mouri Kogoro looked puzzled, 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 underneath the painting.
However, looking at the combined thickness of the painting and the frame, the gap in the middle should feel hollow.
Mouri Kogoro pointed at the painting and asked Anton behind him: "Mr. Anton, is there anything else in this painting?"
"Ah?" Anton hesitated and replied, "It's to protect the paintings..."
However, Mouri Kogoro was not that slow, and judging from his uneasy reaction, it seemed that there was something else going on.
"Do you mind if I take it apart and take a look?"
"dismantle……"
Before Anton could agree, Mouri Kogoro took apart the back panel of the solid gold picture frame.
A glass mirror is inserted into the gap between the back panel and the painting.
But there is not just one mirror, but three.
"Mirror?"
"Mr. Anton, please explain what is going on?"
"this……"
Seeing that the important crime tool was discovered, Anton could only continue to speak harshly, "I just said it was to protect the painting from being crushed..."
"But didn't you just say that this painting was a fake?"
"...Although it is a fake, it must be delivered to the customer intact..."
"is that so?"
Mouri Kogoro's eyes were doubtful, but he couldn't find a better reason to doubt it for a while.
But Conan looked at three mirrors of the same size, then turned to look at the door behind him, and his mind exploded with a bang.
I understand!
I see!
A confident smile appeared on Conan's lips, but he seemed to be obediently exiting the room on his own initiative, but in fact he came to the door, pointed at the door and shouted.
"How interesting! The area of this door seems to be almost the same as the three mirrors put together!"
"What?"
Mouri Kogoro suddenly turned around, looked at the door pointed by Conan, and then looked at the three mirrors placed on the table.
These three mirrors have no frames and have the same specifications. There is adhesive 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, Mouri Kogoro 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 seen in the mirror."
"Because the train was passing through a tunnel at the time, and the lights in the corridor were relatively dim, it was inevitable that we would see it wrong."
"In order not to notice that the house number reflected in the mirror was wrong, you deliberately covered this position with red paint so that the house number could not be reflected..."
"The conductor said that he saw a human figure in about 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 happens to be Room C..."
"That's your room, Mr. Anton!"
Mouri Kogoro put his hands in his pockets with a confident smile on his lips.
This cool and handsome reasoning even made Conan smile with relief.
This time I only gave a little prompting and was able to say so much in one breath. Uncle has made some progress~
The same thing happened with the last "Aphrodite" incident. Kogoro Mori found the real murderer before he did.
That time even Conan had to admit that his levels were not as good as Mouri Kogoro's.
Of course, they both lost to Qin Zhibo who was standing 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. Mori, 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 room C was open at that time, right?"
Anton turned to look at the conductor, who nodded in agreement, saying that he indeed did not notice that the door of room C was open at that time.
This question stopped Mouri Kogoro, and his expression that was very handsome and confident a second ago suddenly turned into a deflated and cute look.
"Well... you should have walked out of the room after killing the person, walked to the corridor and opened the door of room C. The conductor just didn't see it..."
"How is this possible?!"
Anton's voice became louder, "The conductor even saw the figures in the corridor. If I came directly to the corridor, I would be discovered immediately!"
"Um, well..."
Seeing that Mouri Kogoro couldn't explain himself, Conan slapped his forehead helplessly.
I really overestimated him just now, and even forgot the most common techniques...
I originally thought I could save an anesthetic needle this time, but I had no choice.
Conan took off the watch cover and planned to give Mouri Kogoro a happy one.
But at this moment, a palm gently patted his back.
This startled Conan, who quickly closed the watch cover and looked back.
The passenger named "Noto" handed him a slender rope and said with a smile: "Kid, this rope is for you to play with."
Give me a rope to play with?
You really treat me like a child, what's the fun?
Conan took the rope doubtfully. When he was puzzled, he suddenly thought that this thing could be used to demonstrate the techniques of the case.
So, he directly put the rope on the door handle, then grabbed one end of the rope with his left and right hands and pulled it left and right.
The rope pulled left and right causes the door to swing left and right.
"Hey~ This is so fun!"
"It's so fun~!"
Mouri Kogoro was upset when he couldn't answer the question. He suddenly turned around and saw Conan having a high time with Ichimon, and he immediately became very angry.
Just as he was about to reprimand, something suddenly occurred to him.
"yes!"
"You only need to use a rope, fishing line, etc. 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 a strong pull."
"In other words, your complete crime process is like this..."
"Mr. Anton, you designed a false reasoning puzzle in advance and asked Mr. Murohashi to exchange rooms with my daughters so that you can carry out your murder plan."
"Before the train was about to enter the tunnel, you, as a "prisoner", discussed the reasoning puzzle with Mr. Murohashi on the phone."
"After the train entered the tunnel, you said that the signal was not good 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 before. The door was opened just enough to cover up your movement of leaving your room."
"After you finished killing people in room B, the conductor was called to the other side of the carriage by Miss Deha who complained about strange noises in the room."
"At this time, you can use the method I just mentioned to open the door of Room C, use the mirror behind the door to cover up your whereabouts, and at the same time, you can blame Mr. Noto in Room A."
"Am I right?"
Mouri Kogoro showed a confident expression. This time he was completely confident.
Anton, who was hit hard, turned pale and had cold sweat on his face.
But he still has to make a final struggle.
"Then what's going on in the secret room in Room B?"
"Didn't the door of Room B have an anti-theft chain? If I killed someone, how did I leave?"
This time, Kogoro Mouri was asked again, showing an embarrassed expression.
Conan at the door also looked stunned. He was too preoccupied with thinking about the method of committing the crime and forgot to think about the secret room method.
But now that the murderer has been identified, it is only a matter of time before he finds out the method.
Just when Conan turned around to look for evidence, a loud voice suddenly sounded from 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, Mouri Kogoro suddenly became energetic.
"I know! The anti-theft chain in Room B has also been modified by you in advance!"
"As long as the number of anti-theft chains is lengthened, you can hang up the anti-theft chains even when you are standing outside the door!"
The breakthrough of this last key point was like the last straw that broke the camel's back, knocking Anton completely down.
"It's all that guy's fault!"
"If this guy hadn't done something like that five years ago, I wouldn't have killed him at all!"
