Chapter 139

Gao Cheng closes the wooden door from the inside.

The latch is just a simple iron bar, 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 in this photography Institute.

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

Gao Cheng holds the iron bar with obvious friction marks. It looks very new. In addition, there are many scratches on the door, especially on the upper part of the hook. There are impact dents on the left and right areas, which can match the iron bar vaguely.

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

Gao Cheng closed his eyes slightly, supported his chin and went to the position where Lin Yuan taoxiang was hanging.

At that time, there was another suspicious point. He remembered that the buckle on the heel of the sock seemed to be loose.

Different from ordinary modern socks, the socks worn by Lin Yuan taoxiang are also called foot bags, which are also called ancient Japanese socks. They first appeared in China and are specially used to match with clogs.

It's different from using buttons to fasten the foot bag in the past. Now we mainly use the metal hook. Of course, it's strange that Lin Yuantao didn't fasten the heel of the foot bag anyway. Even if he didn't wear clogs, there's no reason to loosen the button when he committed suicide, and

Gao Cheng thinks about picking up the iron bar and looking up at the crossbeam.

If the killer released the clasp, it would just be possible to use the two feet of the corpse to cover the iron bar. The marks on the two wooden doors seem not so simple. There must be some connection between them.

"Wait a minute."

Gao Cheng's line of sight sweeps through the wooden door and suddenly looks back at the crossbeam.

It's a bit strange that Lin yuantaoxiang is suspended in the middle of two wooden doors

The wooden door bolted from the inside, the latch, the marks of friction and even impact on the door, the corpse hanging from the back to the exit, the foot cover not buckled, and finally

Gao Cheng looks at the faint rope scratch on the beam and narrows his eyes slightly. Details flash in front of him. His thinking is fast. All around the room is virtualized, and the scene seems to be back in time.

"I see."

……

"What's the matter? Why are we all called here? "

Outside the waiting room, the crew was brought by the dog fed criminal police.

Dog feed also don't know the situation, said: "in fact, the detective from Tokyo asked me to call you all over."

The crowd was discontented: "taoxiang committed suicide. Isn't the case over?"

"That's what he said," said dog feed helplessly. "But he said he must come here. What he said has confirmed that miss taoxiang didn't commit suicide..."

"What's the matter?" The director was upset. "You're a policeman. Why should you pay attention to him? This is the secret room. It's impossible to kill people! "

"Impossible?" Gao Cheng opened the wooden door and appeared in front of the crowd. He said with a smile, "why do you think it's impossible?"

"No need to say? Just look and see? " The supporting actor Ryunosuke Iwasaki yelled to please the director.

"You'll see?" Gao Cheng looked at the rat eyed Iwasaki and asked, "what did you see? Is it impossible to see the door latch from the inside? Let me ask you, is the earth round or square

Iwasaki Longsi felt puzzled: "of course, it's round..."

Gao Cheng asked, "how do you know it's round? You can see that, too? "

"This," Iwasaki long Shibuyu looked at the directors, "we all know that..."

Gao Cheng said with a smile, "that means you can't see it?"

"It's totally different!" Iwasaki said angrily, "now it's the problem of the chamber of secrets!"

"Then I'll show you if it's possible."

Gao Cheng ignored the supporting role, turned to the dog feeding criminal police and the director, and said: "everyone, I'll explain the murderer's secret room technique now. I'll see if it's OK."

Dog feed a few people look at each other, dubiously follow Gao Cheng into the waiting room of Lin Yuan taoxiang.

Dummy props have been prepared in the house, and the scene of Lin yuantaoxiang's hanging is reproduced. As like as two peas, the length of the rope is exactly the same as that of the hanging position.

"After the prisoner killed miss taoxiang, he just hung miss taoxiang on the beam. Let's see the way the rope was suspended," Gao Cheng pushed the dummy. "It's like a pendulum, isn't it? The prisoner used miss taoxiang's body to complete the secret room technique. "

"How is that possible?" Dog feed shook his head and said with a smile, "is it difficult for the murderer to let the body bolt itself?"

"That's right," Gao Cheng handed the iron bar latch to the dog feed. "The technique is not complicated. Careful investigation can still find a lot of doubts. Miss taoxiang's foot cover clasp is loose. If the prisoner inserts both ends of the latch into the clasp gap, he will gently clamp and fix it with the legs of the corpse..."

"Detective Chenghu," said dog feed with a frown, "it's all about the murderer. Maybe miss taoxiang let go of it herself?"

Then dog feed patted Gao Cheng on the shoulder and said, "I know you detectives like reasoning very much, but we can't think that the police are all idiots because of this. We have found what you said, but it doesn't mean anything. Moreover, we have found evidence in Miss taoxiang's personal belongings."

"Evidence?"“ It's a magazine used to cut characters and spell threatening letters. Even the wheat flour you said was found. All these show that miss taoxiang committed suicide because of the previous explosion... "" what about these traces? " Gao Cheng goes to the door and points to the impact mark on the wooden door“ What? " The dog was stunned“ If Miss Tao Xiang committed suicide in fear of crime, are these traces also caused by her? " Gao Cheng didn't say much, but began to explain the murderer's last tactics“ Just now I talked about the pendulum. When the door was open, the murderer pulled the hanging corpse to the door. When he let go of his hand, the corpse would swing in the opposite direction... "At this time, the murderer closed the doors on both sides, and the heel of the swinging corpse just hit the door, and the iron bar would automatically latch the door because of the impact." Gao Cheng said while using a dummy simulation“ But is it really that easy to bolt it up? " The dog said suspiciously“ Of course, it's impossible to succeed at one time, "Gao Cheng said with a smile." there are many marks of being rubbed on the wooden door and the latch. The murderer should have tried this technique many times in order to complete it? "“ This... "Dog feed speechless, repeatedly looked at the hand of the iron bar latch, as well as the traces on the wooden door. It doesn't sound very complicated, on the contrary, it's too simple. But before Gao Cheng's explanation, he couldn't think of these... "Isn't it really suicide?" Dog feed eyes slightly tremble to see Gao Cheng, the detective from Tokyo but just entered the scene to determine that it was homicide, really so powerful“ Who is the murderer? " They swallowed their saliva and watched Gao Cheng's back closely“ I don't know about this, but, "Gao Cheng glanced at the crowd one by one," the prisoners should be among you“ "Ah!"
