Rebirth of Conan as a Detective

Gao Cheng closed the wooden door from the inside.

The door latch is just a simple iron rod, and the door is just an iron hook. Although it is not complicated, it is quite difficult to use any tool to latch it from the outside, at least it is very difficult to do in this photography studio.

But it's not impossible to make a secret room...

Gao Cheng was holding an iron bar with obvious friction marks, which seemed to be very new. In addition, there were many scratches on the door, especially above the hook, and there were impact dents on the left and right areas, which could vaguely match the iron bar. .

These traces may not have been found during the police inspection, but they just didn't pay attention, because these alone can't explain anything.

Gao Cheng closed his eyes slightly, propped his chin and walked to the hanging position of Lin Yuan Taoxiang again.

There was something more suspicious at the time. He remembered that the heel buckle of the sock seemed to be loose.

Different from ordinary modern socks, the socks worn by Hayashibara Momoka are also called foot bags, which are ancient Japanese socks. They first appeared in China and were specially designed to match clogs.

Unlike the buttons used to fasten the foot bags in the past, metal hooks are mainly used now. Of course, it is strange that the heel of Hayashibara Momoka’s foot bags is not fastened anyway. …

Gao Cheng thoughtfully picked up the iron rod, then looked up at the beam.

If the buckle had been loosened by the murderer, the corpse's two feet could just wrap around the iron bar. The traces on the two wooden doors seemed not so simple, and there must be some connection between them.

"and many more."

Gao Cheng glanced across the wooden door, then turned his head to look at the beam.

The hanging position of Lin Yuan Taoxiang is really weird, and it happens to be facing the middle of the two wooden doors...

The wooden door bolted from the inside, the bolt and the traces of friction and even impact on the door, the body hung with its back to the exit, the loose footgear fastened... and finally...

Gao Cheng looked at the faint rope scratches on the beams, squinted his eyes slightly, details flashed in front of him, and the surroundings were all virtualized as his thoughts ran rapidly, and the scene seemed to go back in time and return to the time when the crime happened.

"I understand."

...

"What the hell? Why did you call us all here?"

Outside the waiting room, everyone in the crew was brought over by the dog breeding criminal police in a daze.

Inukai couldn't figure out the situation and said, "Actually, it was the detective from Tokyo who asked me to call everyone over."

Everyone looked dissatisfied: "Tao Xiang committed suicide, isn't the case over?"

"That's what I said," Inukai said helplessly, "But he said he must come over, saying that he has confirmed that Miss Taoxiang did not commit suicide..."

"What are you doing?" The director was upset, "You are a policeman, why should you bother with him? This is a secret room, it is impossible to kill people!"

"Impossible?" Gao Cheng opened the wooden door and appeared in front of everyone, chuckling, "Why do you think it's impossible?"

"Need to say? Just watch it and you'll know it?" Supporting actor Ryuji Iwasaki yelled to please the director.

"You know it just by looking at it?" Gao Cheng looked at Ryuji Iwasaki, who had a mischievous eyebrow and mouse eyes, and asked back, "What did you look at again? Do you think it's impossible just to see the door latched from the inside? Let me ask you, what is the earth?" Is it round or square?"

Iwasaki Ryuji felt baffled: "Of course it's round..."

Gao Cheng asked: "How do you know it's round? You can see it too?"

"Here," Ryuji Iwasaki looked at the director and the others, "Everyone knows this..."

Gao Cheng smiled and said, "That means you can't see it, right?"

"This is a completely different matter!" Iwasaki Ryuji said angrily, "Now it's about the secret room!"

"Then I'll let you see if it's possible."

Gao Cheng ignored the supporting role, turned to the dog breeder and the director, and said, "Everyone, I'm going to explain the murderer's secret room technique now, and you'll know if it works."

Quan Kai and the others looked at each other, followed Gao Cheng into Lin Yuan Tao Xiang's waiting room with doubts.

Dummy props have been prepared in the house, and the scene of Hayashi Yuan Momoka hanged was reproduced.

Even the length of the rope and the hanging position are exactly the same.

"After the prisoner killed Miss Taoxiang, he hung Miss Taoxiang on the beam like this. Let's look at the way the rope is suspended." Gao Cheng pushed the dummy, "It's like a pendulum, isn't it? The prisoner just used Miss Taoxiang dead body to complete the Chamber of Secrets."

"How is this possible?" Quan Kai shook his head and smiled, "Could it be possible that the murderer can let the corpse lock the door by itself?"

"That's right," Gao Cheng handed the iron rod door latch to the dog, "The method is not complicated, and careful investigation can still reveal many doubts. Miss Taoxiang's footgear buckle is loose. Don't close the gap, use the corpse's legs to gently clamp and fix it..."

"Detective Kido," Inukai said with a frown, "It's all about the murderer, maybe Ms. Taoxiang let go of it herself?"

While talking, Quan Kai patted Gao Cheng on the shoulder, and said earnestly: "I know you detectives like to reason, but you can't think that we police are fools just because of this. It can’t explain anything, and we also found evidence in Miss Taoxiang’s personal items.”

"evidence?"

"It's just a magazine used to cut and spell threatening letters. I even found the wheat flour you mentioned. All this shows that Miss Taoxiang committed suicide because of the previous bombing..."

"What about these marks?" Gao Cheng walked to the door and pointed to the bump marks on the wooden door.

"What?" Quan Kai was taken aback.

"If Miss Taoxiang committed suicide in fear of crime, are these marks also caused by her?"

Gao Cheng didn't say much, and directly began to explain the murderer's last method.

"I mentioned the pendulum just now. The murderer pulled the hanging corpse to the door with the door open, and when he let go, the corpse would swing in the opposite direction...

"At this time, the murderer closed the doors on both sides, and the heel of the corpse that was swinging over again just hit the door, and the iron rod would automatically latch the door because of the impact."

Gao Cheng used a dummy to simulate while talking.

"But is it really that easy to lock it?" Dog Kai doubted.

"Of course it's impossible to succeed once." Gao Cheng smiled. "There are many scratches on the wooden door and the latch. The murderer must have tried many times to complete this trick, right?"

"This……"

Quan Kai couldn't speak, and repeatedly looked at the iron bar latch in his hand and the traces on the wooden door.

It doesn't sound very complicated, on the contrary, it's too simple, but before Gao Cheng explained it, he couldn't think of it at all...

"Is it really not suicide?"

Inukai looked at Gao Cheng tremblingly. The detective from Tokyo judged the murder just after entering the scene. Is it really so powerful?

"Who is the murderer?"

Everyone swallowed their saliva and looked closely at Gao Cheng's back.

"I'm not sure about this, but," Gao Cheng glanced at everyone one by one, "the prisoner should be among you!"

"Eh?!"
