"Bang Bang ......"

As the train passed over the embankment bridge, the maid in Room D glanced out the window, and suddenly her ears moved slightly, and she faintly heard the voices of several people outside.

"It's really unlucky," Kidd's voice rang out, "to meet these guys who have been involved in murder again." ”

Uncle Terai, who was dressed as an old lady, said, "It shouldn't matter, right? As long as we don't expose ourselves......"

"Don't underestimate them," said the maid, chagrined, "these men have always had a good nose. ”

"So, do you want to find the young master of the city first......

"Really, I owe that guy a favor again."

"Do you already know who the murderer is?" At the door of room C of car No. 8, Shiliang Zhenchun stared at Gao Cheng, "Are you telling the truth?" And about the secret room technique......"

"It's not a secret room at all," Gao Cheng interrupted, "It's true that when you got to room B, there was an anti-leech chain in the room, but is this sure it's a secret room?" ”

"Of course!" Shiliang crossed his waist and said, "At that time, Conan and I were able to tear off the anti-theft chain with our own hands to get in!" There is absolutely no place to get your hands dirty! ”

"Is it true that there are no hands or feet?" Gao Cheng smiled, "Why do you think that you can only enter if you tear off the anti-leeching chain?" ”

"Please, what's ...... this?"

Sera Zhenjun suddenly blinked, and the rest of the words were blocked.

"Is there any other way?"

"I've already checked it just now," Gao Cheng took out the photo he took with his mobile phone, "The number of anti-theft chains in room B is 6 sections, but the other rooms only have 5 sections, and the problem lies in the extra 1 section." ”

Maori Kogoro was stunned and said, "It's just one more chain, what's the problem?" ”

"In general, the length of the burglar chain is designed to be so long that you can't hang it up or take it off even if you put your hand into the door, but if you have one more section, the situation changes, and even if you are outside the room, you can put your finger through the crack of the door and hang the burglar chain." Gao Cheng explained.

"However, even if it's not a secret room, someone doing this kind of thing at the door of room B will be discovered by the commander, right?" The man with glasses hurriedly said, "Wasn't the commander in the corridor all the time?" ”

"That's why the prisoner made other preparations," Gao Cheng's gaze turned to the man with glasses, "Mr. Captain started to run left and right just as he was about to enter the tunnel, first because there was no light on the call bell to run to the door of room A, because only the lights in room A were broken......

"When Mr. Captain and Mr. Noto of Room A were arguing, Mr. Murohashi of Room B opened the door to check the situation, and the prisoner took this opportunity to enter Room B, and the train corridor was so narrow that it basically blocked the captain's view......

"The prisoner must have called Mr. Murohashi before entering the tunnel, and asked him to go out to see what was going on while the conductor was arguing, and he himself went out to approach Room B, and when the train entered the tunnel, they went to Mr. Murohashi's room together to continue the conversation under the pretext that there was no signal......

"As for the content of the conversation, it is probably the mystery puzzle on this train, because the prisoner in front of him used his forged instruction card to let Mr. Murohashi play the victim, and changed the room to room B of car 8."

Gao Cheng got two instruction cards from Conan.

"Originally, there was no need for such trouble, but this time Mr. Murohashi couldn't make an appointment to room B of car No. 8 as before, which means that the crime scene must be in room B of this car, because of the anti-theft chain that has just been passed, and the broken light in room A......

"Of course, the main thing is that the prisoner himself is in this carriage."

"So," Mori Kogoro snorted, "who the hell is that prisoner?" Even if you can't see it when you go in, you will always be seen by the commander when you come out, right? The commander didn't make it to room E on the other side......"

"The prisoner has long considered this, which is why the commander saw the door of room A open," Gao Cheng pointed to the black bag behind the man with glasses, "I think the key evidence should be in that inexplicably heavy painting." ”

"That," the man in glasses said dryly, "didn't I say that?" It's heavy because ......"

"Because the frame is pure gold, right?" Gao Cheng answered, "Indeed, you said that you specially told everyone as early as when you were at the station......

"So, what kind of client would give you a collection with a solid gold frame for appraisal and safekeeping, instead of asking you to go to the site for appraisal, and you need to send it to Nagoya alone?"

Gao Cheng's eyes were sharp.

"This ......" glasses man sweats like rain.

"The reason why I thought it was strange at that time," Gao Cheng said lightly, "is because of such a valuable thing, even if the painting is a fake, your attitude is too strange, and generally no one will explain the pure gold frame in particular, or in the chaotic place of the station...... Can you tell us about that? Who the hell is that client......

"It's a mirror!" Shiliang Zhenjun removed the frame, opened the inside of the painting, and accidentally found 3 large rectangular mirrors, "And the frame is not pure gold at all!" ”

Shiliang Zhenjun took out the mirrors one by one, and looked at the man with glasses with a solemn expression: "I see, you brought 3 mirrors that were stacked to cover a door, and at that time you opened the door of your room, and the mirror that was pasted on the inside was reflected in advance, and Mr. Captain saw a suspicious person snooping behind the door of room A, but it was actually Mr. Captain himself who was by the door of room E......"

"No," Mori Kogoro questioned, "If it's a reflection, there should be room E number, right?" ”

"Because the place where the door number will be reflected is painted with the same paint as the door," Shira Masumi looked directly at the man with glasses with bright eyes, "Finally, after leaving room B, you first use the alarm clock watch to attract the commander's attention, and then close the door of your room C and pretend that you have just left the room.

"Of course, the alarm watch used to attract attention is also prepared by you, and it should still be a remote alarm."

Shiliang Zhenchun smiled and looked at Gao Cheng with a small tiger tooth: "That's right, Chenghu senior?" ”

"You're done......"

Gao Cheng and Conan stood beside him, paused, and asked seriously at the man with glasses who was in a state of malaise, "So, is the motive related to the fire?" I remember that you were rescued with Mr. Murohashi 5 years ago......"

"Because that fire is Murohashi's masterpiece," said the glasses man's hoarse voice, "The painting that was supposed to be burned in that fire appeared at an auction two years ago, and I found Murohashi after tracking it down, and the fire was to hide his theft, which Murohashi himself admitted before he died......

"I originally planned to persuade him to turn himself in, especially when I learned that Room B of car No. 8 was robbed by Mr. Detective, and I thought that maybe God was stopping me......

"However, even though he killed so many people, Murohashi didn't feel guilty at all, and said with a smile on his face that it's good to be alive, obviously my wife was also killed in that fire!!"

Looking at the man with glasses who was outbursting with emotion, Gao Cheng did not continue to ask.

Perhaps when he was on the platform, he felt the hidden sadness of this man.

There is indeed too much sadness in this world, but no matter how sad it is, killing is always killing, let alone involving other innocent people.

"Really," Maori Kogoro looked at the man with glasses who had confessed his guilt, but he didn't think too much about it at all, but said depressedly, "How can I practice Poirot and not work?" I thought I would be able to solve the case beautifully this time......

"Sure enough, I'm still going to sleep and go out."
