Dressed as a mystery novel victim

The weather was fine that day, and there were many people skating and having snowball fights in the park. The foot of the mountain was lively, but there were not many people hiking up the mountain.

The peak was covered by heavy snow, and the lake was frozen. At this time, hiking up the mountain has a kind of tragic and heroic feeling of climbing Everest, especially for Yang Qingshui.He wrapped himself into a rice dumpling, but the cold wind poured directly into the mouth of the leader of the jacket, and every step he took was blown half a step backward by the wind.

Miao Yi and Jiang Xinxin stared at him with the eyes of appreciating performance art. Miao Yi was very helpless, "Shouldn't a detective be physically strong? How do you usually investigate cases?"

Yang Qingshui is the owner of the golden finger. He only needs to use his memory to investigate the case, and he doesn't have to do the hard work of gathering evidence day and night.

Unless he didn't write the case in the novel.Yang Qingshui sighed, "Life is forced."

Stepping on the pine needles all over the ground, although the forest is a hidden place to kill people, it is not easy to hide the traces, the corpse is easy to be found, it is better to put some thought into pushing people off the edge of the cliff, watching her die without rescue, who can judge Is this a murder or an accident?

Yang Qingshui was thinking about it, when Miao Yi asked: "Can you tell us now, why did you arrest the people who worked for Shu Wen?"

There were not many people in the car along the way, so it was inconvenient to ask in detail. Finally, when they arrived at a remote place, there were only three of them left. Miao Yi couldn't help asking.

"The people in your team are really curious. I read in the newspaper yesterday that Kong Xinliang was invited back by the criminal police to assist in the investigation at the gate of the parliament. Several media were there at the scene. The political line they were following suddenly changed to the criminal investigation line. Foggy, right?"

"Not only—" Jiang Xinxing was about to give a special speech, but Miao Yi pushed his elbow, so he had to close his mouth.

Miao Yi simply added: "The news has been very hot these days. A series of accidents are suspected of being a murder case. It is enough to talk about. If you add a big shot, this fire can burn for a long time. Now the police station is still squatting With a large group of reporters."

"Kong Xinliang jumped up and down the police station, right?"

Miao Yi nodded hesitantly. Originally there was no evidence to arrest people and they were all in a panic, but Kong Xinliang reacted hysterically, so guilty that one could not help but suspect that he was really related to the murder.

Yang Qingshui took out a roll of paper from his coat pocket and blew his nose. After freezing for a long time, his head buzzed, "The evidence is annihilated, and the deceased cannot speak. There is no better way than letting the murderer speak automatically."

The two looked at each other, and Jiang Xinxing asked in amazement, "Let the murderer speak?"

"Where should I start?" Yang Qingshui said to himself, solving the case was no fun for him, let alone deconstructing the case, "Do you know the Prisoner's Dilemma?"

It was a classic theory of game theory, and both men nodded.

Suppose two people who conspired to commit a crime are imprisoned and unable to communicate with each other.If neither confesses, both will be imprisoned for one year due to lack of evidence; if one denounces and the other is silent, the whistleblower will be released immediately, and the silent one will be imprisoned for ten years for non-cooperation; The evidence was solid and both were sentenced to eight years in prison.

Since prisoners who cannot communicate will not trust each other, they tend to expose each other rather than silence.The so-called reasonable egoism will make the choice irrational, and smart people will be trapped because of their smartness.

Yang Qingshui: "Killers, intermediaries, gangsters, they are all murderers, and at the same time they keep the other party's criminal evidence. But for certain reasons, they cannot betray their superiors, and they would rather keep silent when they are caught. Only those who stand in front of the crime can be convicted. Killers, unable to shake their roots."

Miao Yi was stunned, "Isn't this contradicting the Prisoner's Dilemma?"

"The breakthrough point is that they believe that their subordinates will and have already betrayed themselves, so they can form a prisoner's dilemma." Yang Qingshui said, "First, there was a murder case where the identity was exposed. The killer was arrested for two days, and then the controller of Shuwen Labor Service was arrested. In the end, it would be logical, and they invited Kong Xinliang to the police station to assist in the investigation. They thought that the pile of dominoes would only be overthrown if the former fell. If they were arrested, they must have been betrayed. They didn't know that the police were only caught in time. .”

"I don't know what the other party confessed. In order to ensure their own interests, they will naturally not be so stupid as to keep silent. This is the beauty of the prisoner's dilemma. Everyone thinks that they have made the best choice, so they capsized together."

Jiang Chuangxin: "If the other party is really stupid, why don't they say anything?"

"It doesn't matter. Think about it. When the subordinates get the news in the detention room and their superiors are arrested, no matter how the identity of the traitors is confirmed, they will have nowhere to go. Unless the superiors are completely finished, whether they go to prison or go out, The only end is death. In this way, in order to survive, the subordinates will become real informers, in order to defeat the opponent, and expose whichever is fatal."

Bei Feng whirred and started talking, Jiang Xinxin couldn't help asking: "Do you really believe that they will expose each other?"

"I believe in human nature. Now that the suspect has been brought back, what will happen will depend on these two days." Yang Qingshui hugged his jacket tightly, "Can't you stand in front to block the wind? My mouth is frozen."

Miao Yi asked: "But how did you find out the relationship between Kong Xinliang and Shu Wen's labor services?"

Yang Qingshui smiled slightly, glanced at her and said nothing.In his experience, time spent in silence while lying often works wonders.

Pausing for a moment, Miao Yi was stunned, realizing what a stupid question he had asked.Yang Qingshui is a professional detective. Isn't it a daily routine for him to spend time tracking and chasing him? No wonder those people would rather expose him than kill him.

She was still laughing at Yang Qingshui's weakness just now, but he was hiding behind his back facing the dragon and tiger's lair alone... Thinking about it, Miao Yi both admired and felt ashamed.

Although I don't know what Miao Yi is thinking, her expression is in stark contrast to Jiang Xinxin who is at a loss. As expected, it is good to pretend to be mysterious, and someone will use their brains to supplement the story for him.

"If there's anything you don't understand, ask your captain." It's too embarrassing to talk about the sixth sense of God in front of the juniors, so Yang Qingshui simply put the blame on Lin Zhilu.

While talking, the three of them finally walked to the mountain path near the peak. Looking up, there are still more than 100 stairs to reach the pavilion for people to rest. Just looking at it makes people shrink back.

Jiang Xinxin stepped on the first step of the stairs and turned his head: "Let's call it a day, I'm afraid you will die here."

According to the archives, the place where Jiang Wei stumbled was not far from the gazebo, and she couldn't give up until this time. Yang Qingshui sniffed, and turned towards the cloud-shrouded peak: "Go up."

There is no artificially excavated passage further up, and only professional equipment can be used to go up the mountain. The gazebo is already a place for sightseeing hikers to climb to the top.The pavilion was engraved with the word "Wangyou" in seal script. It was near this pavilion that Jiang Wei fell off the cliff and died on the spot.

It took a full hour and a half from the accident to the arrival of the rescue team. During the 90 minutes without monitoring, was her husband Qi Zhong anxiously waiting for rescue, or was he busy destroying the evidence?

At this time, Jiang Xinxin glanced at the outside of the gazebo, "The bottom here looks like a grassy slope, but it's actually on the edge of a cliff. It staggered and rolled directly into the valley, and the bones couldn't be found."

After Jiang Wei's accident, the company in charge of the scenic spot added stone fences due to pressure from public opinion. The fences were higher than Yang Qingshui's knees. It was impossible to intercept the cliff jumping, just to buy peace of mind.

Yang Qingshui climbed over the fence and walked towards the boulder on the grassy slope.

"Hey!" Seeing him walking step by step without listening to his calls, the two people in the gazebo realized something was wrong, turned over three steps and made two steps, and caught up with Yang Qingshui.

Yang Qingshui raised his hand to stop the two of them.

Jiang Xinxin stopped suddenly, his center of gravity was unstable, and he staggered for several steps, but luckily Miao Yi caught him.With lingering fears in his heart, he angered the instigator: "What are you going to do, commit suicide and don't drag the two of us behind!"

Yang Qingshui ignored him and squatted down.

The photos taken by Jiang Wei before her death were printed and developed by Jiang Zhenli and his wife. Three of them are photos of her sitting on a rock in different clothes. Jiang Wei is keen on looking at the scenery. There are three photos, which shows that she is willing to visit Changkuan almost every time. It's not easy for a girl to sit on boulders and just climb up.The boulder has the length and width of three people hugging each other, and the edge is steep. You need to support the edge of the stone, push your feet up, or get help.

Before Jiang Wei's accident, Qi Zhong claimed that he was buying drinks for his wife on the mountainside. He talked for a long time, and even the owner of the grocery store said that he knew this person when he testified. He had sufficient evidence of his alibi.

Soon, Yang Qingshui discovered the leak. Near the foot, there were several narrow and long thin marks on the stone.It was sharp and imperceptible, as if it had been scratched by a steel wire.
