Xie Xuan didn't know what she was thinking, so she found a comfortable position and leaned on the pillow, then put her legs on the low stool. When the waiter and Wenmo came forward to beat his legs and squeeze his shoulders, he asked with interest: "What is the chain of evidence?" ”

Knowing that he was just asking casually, maybe he didn't care at all, but with the idea that to correct his concept, he had to start small, Chen Chaoyan still replied seriously: "The chain of evidence refers to the evidence system that can corroborate each other and completely prove the process of the crime by collecting evidence such as human evidence, physical evidence or confession. Taking Ma Huai as an example, although the physical evidence and human evidence found so far prove that he is the murderer of Zhou Zhongcai, Shi Zhi and Li Er, it is also an objective fact that he does not know Li Er. ”

"Take Ma Huai as an example...... "Xie Xuan said in a low voice, then said solemnly, "Ma Huai said that he didn't know Li Er, but he said that there is no evidence to prove that his words are true." In other words, except for not knowing Li Er, all the physical evidence and human evidence found so far can corroborate each other. ”

Chen Chaoyan: ......

This is a fact, and she cannot refute it.

Xie Xuan looked at the dumb appearance she wanted to say but couldn't say, and silently hooked the corners of her mouth and laughed, "Miss Chen actually knows, with the current evidence, it is completely enough to convict Ma Huai." ”

That's true, but ...... Chen Chaoyan tried his best to fight: "Yes, as far as the evidence found out, Ma Huai can indeed be convicted." But has the prince ever thought about it, if it is really Ma Huai, why did Wang Da and others shield him? ”

Xie Xuan reminded slowly: "Miss Chen has forgotten again that two years ago, Ma Huai committed a crime in Zhangwa Village. If this case hadn't been for his uncle and uncle confessing to him for self-protection some time ago, Zhou Zhongcai would have died as soon as he died, and it could be said that the clouds would have disappeared. In the same way, if he had committed a case similar to Zhou Zhongcai before, because it did not involve his own safety, no one came forward to confess, which is also very normal. ”

After a pause, he said again: "There are two murderers, but it doesn't mean that these two people must be in the county guard." ”

This is indeed possible, Chen Chaoyan nodded in agreement, and then wanted to say how to deal with it. But at the moment when the words were about to come out, after meeting his teasing eyes, I suddenly understood the reason for his aggressiveness!

After closing his eyes slightly and suppressing the emotions of overturning the river and the sea, Chen Chaoyan turned his head to look at the scenery outside.

Puzzled, Yuejian asked the waiter, "What's wrong with Miss Chen?" ”

The waiter glanced at Chen Chaoyan and said in a low voice: "Miss Chen is too obsessed with the conclusion that Ma Huai is not a murderer, so that she is upset. ”

yes, her heart was upset.

The purpose of her continuing to investigate this case was to catch the real murderer, not to overturn the case for Ma Huai. Therefore, the correct approach should be to integrate all the evidence and sort out the clues as when the case was first investigated, and then clarify the direction of the investigation before conducting the investigation. Instead of seizing on a guess and disproving the existing evidence, as is the case now.

Xie Xuan saw that she was going in the wrong direction, so he would use her wrong direction to refute her speculation, so that she would repent when there was no way out.

"Is this sluggish?" Seeing that she hadn't spoken for a long time, Xie Xuan teased.

"Nope." Chen Chaoyan turned his head, his eyes calm and sincere, "I'm just thinking about how to thank the prince." ”

"Have you thought about it?" Xie Xuan asked lazily.

Chen Chaoyan hooked the corners of his mouth, "Lord Wang help me refer to it?" ”

Xie Xuan chuckled, "Let's hear it." ”

Chen Chaoyan thought for a moment, then said slowly: "There is no doubt that the eight people with fingerprints on the deed may be murderers. Among the eight people, Lord Feng and Zhao Wuwei stayed in the county guard mansion on the night of Zhou Zhongcai's murder, and there were officials who guarded the government to testify, and Lord Feng did not know martial arts, while Zhao Wuwei has been following him since Lord Feng became an official, and the two are considered a community. The two of them had no dealings with the Silver Hook Cabinet Workshop, and more importantly, they only came to Luyang County in the first half of the year. The county guards and magistrates of the Great Wei Dynasty are all replaced every four years. Where it will be replaced next time is up to the Ministry of Officials. In other words, it is very unlikely that Lord Feng and Zhao Wuwei are one of the masterminds behind Zhou Zhongcai's power and money. ”

"Since it is very small, then their suspicion can be ruled out for the time being."

Xie Xuan nodded, "Go on." ”

"Uncle Sun is the county guard who went two years ago, before entering the county guard, he worked in the county government of Jianing County, there is no way to lie, so his background is simple and clear. In addition, judging from his own conditions, family conditions, and the flow of people, the possibility of him being the murderer is also very small. Chen Chaoyan said.

Xie Xuan nodded again.

"Ma Huai......" Chen Chaoyan was silent for a moment before he said, "I run a pharmacy at home, so I can be said to be familiar with the human body. It is the judicial history of the judicial department of the county guard, and it can also be said to have anti-reconnaissance capabilities. In addition, he participated in the tragedy of the Bao family's annihilation and knew martial arts. Coupled with all the evidence that has been investigated, he is undoubtedly the most likely murderer. ”

"As for whether he has committed the same case as Zhou Zhongcai in the past, my proposition is that when he returns to Luyang County, he will focus on investigating the reasons why he entered the county guard's mansion, such as whether it is because of power or money."

There were wisps of appreciation in Xie Xuan's eyes, and the calm and calm Chen Chaoyan returned.

"In addition," Xie Xuan restrained his emotions when she looked over, and added slightly, "You can also start to check if there is a possibility of stealing their fingerprints without the person's knowledge." ”

Chen Chaoyan's eyes lit up for a moment, but then he shook his head and said, "It's not difficult to steal his fingerprints, but what is the reason for stealing his fingerprints?" I'll fingerprint to solve the case, but I've never said it to the public. ”

Even if Ma Huai was arrested, it was based on the evidence of those secret letters, not the fingerprints on the secret letters.

"Muyuan Hall and Star Picking Pavilion have the murderer's eyeliner?" Tsukimi asked.

"Impossible." The servant said, "The maidservants who served in Muyuan Hall and Star Picking Pavilion, Ling Quan has secretly checked their identities. In addition, their daily words and deeds are also monitored. ”

Tsukimi said, "What's going on?" ”

Chen Chaoyan wrinkled his eyebrows and looked at Xie Xuan.

Xie Xuan said: "The murderer of Zhou Zhongcai, whether it is an individual or an organization, just because he does not leave many other clues except for fingerprints, it can be seen that it is not simple. And we have been collecting fingerprints, even if the murderer does not know what it is for, but there is a precedent for solving the case in the form of bloodstains, which does not prevent him from making correct guesses. ”

The waiter glanced at Chen Chaoyan quietly, "According to Gongzi's analysis, those secret letters are the murderer's temptations?" ”

Xie Xuan didn't answer, but looked at Chen Chaoyan and motioned to her with his eyes to say how she could collect his fingerprints without alarming Ma Huai.

Chen Chaoyan said: "After excluding Lord Feng, Zhao Wuwei, and Sun Bo, the five suspects Qian Wen, Wang Da, Song Yanzhong and Shen Jimin are all Ma Huai's superiors. If you want to extract his fingerprints, you can easily find a reason to achieve your goal. ”

At this point, Chen Chaoyan suddenly said after a pause: "The paper of the three secret letters ......"

At the same time, Xie Xuan also said this.

The two looked at each other, and they both saw a smile in each other's eyes.

Obviously, they all thought about the middle-aged man's money loss case in Beilu County at the same moment. The key to solving the case is on the cloth that the middle-aged man packs the money. In the same way, the Great Wei corresponds roughly to the Tang Dynasty part of the historical torrent known to Chen Chaoyan. This part of the paper is still a luxury. Therefore, as long as you start with the paper, you can further lock the murderer.

The moment the two mentioned the paper, the waiter and Wenmo also thought of the middle-aged man's money loss case at the same time. Wenmo said little, and the one who spoke was still the servant, "The three secret letters are made of jute paper from Shu County." ”

Knowing that Chen Chaoyan didn't know anything about the court, the servant specially explained to her: "The major yamen of the Great Wei Dynasty used white and jute paper from Shu County. White linen paper is used for official use that needs to be submitted to the ministries for retention or ordered by the ministries, and jute paper is the daily paper used by the yamen. But whether it is white linen paper or jute paper, there is a quota. After returning to Luyang County, let Sicang Cao check the quota of each Cao, and then check the common number of each Cao, so where the white linen paper used for the secret letter comes from, it can be clear at a glance. ”

Chen Chaoyan quickly took the note and said, "Qian Wen, Wang Da, Song Yanzhong and Shen Jimin just belong to the same Cao!" ”

The waiter said 'um'.

Ling You said excitedly: "Is it possible to prove who the murderer is as long as you find out which Cao is missing the white linen paper?" ”

Chen Chaoyan shook his head, "No." ”

Ling You asked, "Why?" ”

Chen Chaoyan said: "Because there is no evidence. ”

Ling You scratched his head, "Miss Chen, are you confused, isn't the white linen paper the evidence?" ”

Yuejian said disdainfully: "Stupid, the white linen paper is evidence, but there are no fingerprints on it, as long as they say that they don't know, they can push it all away!" ”

"You're stupid!" Ling You scolded. He asked like that, just to set off Chen Chaoyan's cleverness, who rarely asked her to talk!

Yuejian snorted coldly, "Miss Chen's ability to judge cases and conduct autopsies is real, but it's not something you touted!" ”

"I just like to brag about it, what do you have to do with it?" Ling lobbied.

"I just can't get used to you, how?" Tsukimi replied.

The two of them didn't face Mai Mang once or twice, Chen Chaoyan had long been accustomed to it, and seeing that Xie Xuan didn't care, he continued what he said just now: "Ma Huai here, I started to re-check from the reason for entering the county guard mansion and the three secret letters, I don't know if the prince has anything to add?" ”

Xie Xuan knocked on the table, "No." ”

"Qian Wen doesn't know martial arts, and he didn't go to Yunliang Pavilion on the night of Zhou Zhongcai's accident, although he had transactions with the Silver Hook Cabinet Workshop, but judging from the results of the early investigation, his life is relatively simple, almost a two-point line between the county guard and his family, and Zhou Zhongcai, these assistants, historians, and officials are not too much in private. My opinion is that by grasping the big and letting go of the small, we can temporarily rule out his suspicion. After Chen Chaoyan finished speaking, he looked at Xie Xuan, "What does the prince think?" ”

Xie Xuan hooked the corners of his mouth imperceptibly, "Yes." ”
