According to previous speculation, it is very likely that Tang Hong's murderer took advantage of the fact that the surveillance camera maintenance worker had something to do with Xiao Wang on the way to Tang Hong's clothing store.

In the face of Ling Yu's questioning, Xiao Wang obviously knew something, but at the same time, his expression was also very nervous, as if he was telling Ling Yu that he couldn't hide something.

At this time, in the office of the maintenance shop, Ling Yu let everyone except Xiao Wang and Shu Xiaoran leave the office, and some things were inconvenient for others to know.

"Now there are no outsiders here, you tell me everything you know that night." Ling Yu said to Xiao Wang.

After Ling Yu finished speaking, Xiao Wang took a deep breath and replied: "Here's the thing, at ten o'clock in the evening on July 6th, I received a call from Tang Hong's clothing store, the content of the call was roughly that the surveillance camera of her clothing store was broken, let me go to repair, I was still a little strange at the time, it was already so late, why not wait until the next day to repair." ”

"After that, focus on what happened to you on the way there." Ling Yu added.

Xiao Wang continued: "On the way to do a very strange thing, I have nothing to hide, to get to Tang Hong's clothing store must pass through a corner alley, there is no street lighting, so I can only rely on the night to move forward, but when passing through that alley, I have a feeling of being covered from behind, and then I smell a strange smell, and then I seem to lose consciousness, my whole body is weak, I fell asleep, when I woke up, It was about four o'clock in the morning, and my work clothes were gone, and the tools in the toolbox were gone, but it seemed that I had inhaled that strange thing, so I was a little confused at that time, because there was basically no one in the alley, so I was never noticed, and then I went home and changed my clothes and returned to the office. ”

"Then why didn't you tell the police about these things in the first place?" Shu Xiaoran said.

Xiao Wang's face was a little nervous, as if he had been worried about something: "After I returned to the maintenance shop after changing my clothes that day, the news of Tang Hong's murder came immediately, I was worried that this matter had something to do with me, once it was known, it was very likely that the repair shop would be involved, I still have a wife and children at home, if the boss fired me because of this matter, then how can I support them." Xiao Wang said that he was a little excited, and he was obviously scared but still angry.

Ling Yu couldn't help but lean back from the chair and sighed.

Although Xiao Wang was negligent, he did not tell the police such an important matter at the first time of the crime, and hid it from the boss and the police, but I have to admit that what Xiao Wang was worried about was not false. In the current society, not everyone can have a eating vessel, although some people have a eating vessel in their hands, but if they can't keep it, the rice bowl will be overturned. For people in Xiao Wang's situation, they don't seem to have the right to choose, only the fate of being chosen.

After asking Xiao Wang, Ling Yu Shu Xiaoran walked out of the office with Xiao Wang, and as soon as they opened the door of the office, the three of them saw the person in charge standing at the door, who seemed to have been waiting for the final result here.

"Two police officers, is something happening to Xiao Wang?" The person in charge asked Ling Yu and Shu Xiaoran.

I saw that the words of the person in charge had just fallen, Xiao Wang's face turned white all of a sudden, from his heart, Xiao Wang now seemed to have guessed that he was about to leave his post and cooperate with the police investigation.

Ling Yu replied:

"After interrogating Xiao Wang, Xiao Wang has no connection with this case, and he also provided us with very important clues."

"Oh yes, it's our greatest honor to be able to help two officers." The person in charge replied.

Ling Yu's answer made Xiao Wang a little shocked, he didn't expect Ling Yu to say this. Gradually, Xiao Wang's face also improved a little. Ling Yu continued: "We all know about the situation, so let's go back first, if you still find any important clues, you must contact us in time." ”

"Okay, we'll report back if there's a situation."

"Let's go, Xiao Ran." Ling Yu turned his head and said to Shu Xiaoran.

"Xiao Wang, send the two." The person in charge also said to Xiao Wang.

Ling Yu and Shu Xiaoran followed Xiao Wang to the door of the maintenance plant, and when Ling Yu was leaving, Xiao Wang couldn't help but ask Ling Yu: "Why don't you tell the truth to my person in charge?" ”

Ling Yu turned around and replied to Xiao Wang: "You have already told us everything you know, and we have also got the clues we want to know, there is no need to pursue your mistake this time, but the next time you encounter this kind of thing, you must call the police as soon as possible, not to mention that you still have a wife and children, what should you do if you accidentally lose your job." ”

Xiao Wang lowered his head and didn't know what to say, in this era, it is indeed as Ling Yu said, the rule of the world is that if you don't have enough ability, you will be eliminated. When he raised his head again, he saw that Shu Xiaoran and Ling Yu had already gotten into the car, and Ling Yu rolled down the window glass and said to Xiao Wang before driving: "Hey! Don't think so much, do your job well, and one day you will be able to control your own destiny! ”

After Ling Yu finished speaking, he drove away from the repair shop, and Xiao Wang was the only one left at the door of the repair shop. In the car, Shu Xiaoran, who was in the co-pilot's seat, asked Ling Yu: "I can't see that you have always been cold and arrogant, but if the person in charge really knows what happened to Xiao Wang that night and did not report it at the first time, it is estimated that Xiao Wang will really be fired." ”

Shu Xiaoran looked at Ling Yu and was waiting for Ling Yu's answer, but Ling Yu sneered and replied to Shu Xiaoran: "I'm afraid the person in charge has already seen it." ”

Ling Yu's words, Shu Xiaoran didn't understand.

After Ling Yu and Shu Xiaoran left, Xiao Wang walked back from the door of the maintenance shop, and when he returned to the office, Xiao Wang saw that the person in charge was sitting inside, and Xiao Wang was just about to say something: "Director, I..."

"What are you, there is still a bunch of work to deal with in the back, hurry up and go door to door to repair." Before Xiao Wang's words were finished, the person in charge answered.

"Uh-huh, I'll go."

After Xiao Wang left, the person in charge said to the people around him: "Go and inform the operator on the other side, and try to arrange as much work as possible for Xiao Wang, so that he can earn a little more." ”

"Okay, Director, I'll do it."

After they all left, the person in charge sighed on the spot and continued to do his work at his desk. Maybe the person in charge already knows about Xiao Wang, or maybe he doesn't know, but whether he knows it or not, Xiao Wang has been taken care of by the person in charge. In today's society, we don't have the power to completely change everyone's lives, but we can do our best to help them.

【Chengguang City Public Security Bureau】

After returning to the police station, Ling Yu and Shu Xiaoran began to analyze and discuss the case in response to the clues provided by Xiao Wang. According to Xiao Wang's oral account, on the night of Tang Hong's case, Xiao Wang was covered with a wet cloth on the way to Tang Hong's clothing store and fainted. This method is similar to Gao Bin's case, although Xiao Wang was not killed, but the way of victimization is the same. It's just that Xiao Wang didn't find it in time, and there were no bruises left on his body after struggling.

Assuming that the person who killed Xiao Wang was the one who killed Tang Hong, then after knocking Xiao Wang unconscious, he wore Xiao Wang's clothes, took the tools in Xiao Wang's toolbox, and then disguised himself as a maintenance worker and came to Tang Hong's clothing store, making Tang Hong mistakenly think that he was a maintenance worker, making him relax his vigilance and kill Tang Hong while Tang Hong was unprepared.

For Gao Bin's case, the person Gao Bin himself agreed with was a person in the hotel, and if the murderer came to Gao Bin's room before the person who was agreed to and killed Gao Bin, it was easy to do it without anyone knowing it with the advantage of not having a camera.

But Ling Yu deduced one thing from the clues he had so far, that is, this murderer must have an advantage in chemicals, such as the drugs that fascinated Xiao Wang and the blue and white armor that suffocated Gao Bin proved the murderer.

At the same time, Chu Ming also had news here, about Tang Hong's previous bill that did not match the number, Chu Ming found out that someone deliberately used the network to implant a virus in Tang Hong's computer, and then stole the bill information and modified it, after understanding this situation, the mystery of Tang Hong's bill was solved. It's just that the computer skills of the person who modified the bill are not bad, and he hid his IP address, and Chu Ming has no way to trace it.

But at the same time, a question arises about the relationship between the person who modifies the bill and the murderer, whether he and the real murderer will be the same person, and the relationship between the person who knows about chemicals and the real murderer. Old mysteries are solved, and new ones reappear.

Now, most of the doubts in the two cases have been resolved, but there is no news from Qin Jian so far.

While handling the case, Ling Yu also tried to get in touch with Qin Jian, but every time it was in vain, Chu Ming's side still couldn't locate Qin Jian's position. At this juncture, the two cases had not been solved, and Qin Jian disappeared without a trace. But there's more to it than that.

At this juncture, the office alarm phone rang again. Shu Xiaoran, who was next to the phone, picked up the phone:

"Hey! What the...... Okay, I got it. ”

After telling the specific situation on the other side of the phone, Shu Xiaoran's face was shocked, as if it was expected and seemed to be unexpected.

Putting down the phone, Shu Xiaoran looked at Ling Yu and Chu Ming, Chu Ming and Ling Yu were also waiting for Shu Xiaoran to say something.

"What's wrong, Xiao Ran?" Ling Yu couldn't help but ask.

"Boss, it's a call to the police." Shu Xiaoran replied.

"Is there something going on in Liu Xuan's house!" As soon as she heard that it was a police call, Ling Yu's first reaction was Liu Xuan, and according to the previous reasoning, the next victim was likely to be Liu Xuan, the most famous writer now. According to the plot of the movie "The Entrance to Heaven", there is a chance that the next victim will be him.

But Shu Xiaoran replied: "No, it's not Liu Xuan!" ”

"What! Who's that! ”

This may be the reason why Shu Xiaoran was surprised just now, he didn't expect that the victim was different from what he had predicted before. Ling Yu was a little anxious and stood up directly from the chair.

Shu Xiaoran replied: "The deceased's name is Robert!" ”

"Chu Ming, investigate all the information about this named Robert." Ling Yu said to Chu Ming.

"Don't worry, boss!" Chu Ming said as he began to tap on the keyboard.

On the other side, Ling Yu asked Shu Xiaoran about the specific case.

"The deceased was found dead this morning in the study of his mansion, the cause of death is still unknown, according to the preliminary examination report at the scene, the deceased had a wound on his neck, and the body was covered with blood. However, a small amount of chemical was found in the body, and the exact content of this substance will not be determined until it is tested at the scene. Because it was only a preliminary examination, it was not possible to determine whether the deceased died of poisoning or because of excessive blood loss due to having his throat cut. ”

Shu Xiaoran continued:

"There are a few more points, when the housekeeper of the deceased's family went to the study today, he found that the door of his study could not be opened, and the key was only held by Robert himself, and the study generally did not lock the door, seeing that the door could not be opened, and there was no trace of Robert at home, the housekeeper was afraid that something would happen and called a few people to destroy the door of the study, and went in to see that Robert had died on the desk, so he called the police, and our people observed that the deceased was still holding a knife in his hand, and after verification, the knife was a knife used daily in the deceased's home, However, there was no one on it except the fingerprints of the deceased himself. ”

On the other side, Chu Ming also sent detailed information about Robert.

Robert, formerly known as Ma Fulin, 45 years old, a famous opera artist, renamed Robert after engaging in the opera career, the winner of the 19th Opera Directors Award, won the Best Opera Writer and Director Award again in 06 years with his original opera "Lost Paradise", and was invited to Sydney to perform opera, which has few reputations in the world. But a piece of information about this person around the age of 30, that is, before he became famous, was erased, and there was no way to find it.

After investigating Robert's details, Chu Ming also made a phone call to Liu Xuan's home, and there was no problem on Liu Xuan's side. Could it be that there is something wrong with your previous assumptions? The phenomenon of Tang Hong's death of Gao Bin is exactly the same as the plot in the movie, but the third deceased did not follow the plot in the movie, is there no connection between the third deceased and the previous two cases?

"Boss, what are we going to do?" Shu Xiaoran asked Ling Yu.

"This is a closed room murder case, I don't know what the death scene looks like, and there are many blind spots, and I will discuss in detail after going to the scene." After Ling Yu finished speaking, he turned around and walked in the direction of the door, Shu Xiaoran followed closely, Chu Ming closed his computer and followed Ling Yu and Shu Xiaoran to the scene in his arms.

Based on the information provided by the previous police call, it is not possible to determine whether this case and the first two cases were committed by the same person.

In less than twenty minutes, Ling Yu and the others felt the scene of the crime, and as soon as they got out of the car, the mansion in front of them was exposed in front of the three of them, and a mansion like this can afford to live in the city except for Robert, I am afraid that there will be no second person. A cordon had been set up around the mansion, and Ling Yu showed her ID to the guards next to the cordon and went to the scene.

"Everybody out!"

After Ling Yu entered, he let all the people before retreat, leaving only Shu Xiaoran and Chu Ming inside. Although some people are also reluctant, everyone knows Ling Yu's temper, and if she provokes her at this time, it will definitely be herself.

The deceased was lying flat on the table in the study, the blood around him had solidified, and as Shu Xiaoran described, the deceased was holding a knife in his hand and had a knife on his throat. After receiving Ling Yu's instructions, Shu Xiaoran stepped forward to take some samples from the deceased and tried to analyze the chemicals in the deceased's body.

So how did the murderer make this secret room, he must know that it didn't look like a suicide, why did he put the murder weapon in the hands of the deceased. Deliberately posing for the suicide of the deceased?

Ling Yu observed this study, if you start to observe from the door of the study, on the right side of the door is a row of windows, which can clearly see the outside, and the windows are open, probably to disperse the smell of corpses in the study as soon as possible. On the opposite side of the door is Robert's desk, and behind the desk is a row of bookshelves with opera scripts written by Robert himself, as well as some of his own drafts. There is also a row of bookshelves on the left, but mainly some foreign masterpieces, and some oil paintings.

Because the door was found after it was destroyed, so now the debris of the study door is piled up in the doorway, Ling Yu swept the handle of the door at a glance, it is a push-down handle, and then picked it up and found that there were a few inconspicuous scratches on it, but it is not clear how it came about.

Ling Yu closed her eyes, and suddenly her mind was speculating on the restoration of various cases, trying to deduce the process of the creation of the secret room. Suddenly, Ling Yu opened her eyes and lowered her head to look for something, as if she had deduced something.

She searched as she went, along the base of the wall, not sparing any corner, and finally her eyes lit up in the place where there was a lot of debris, and she saw several things, as if she had found what she was looking for, and at the same time she understood how the murderer managed to keep the door open. However, although he has understood why the door cannot be opened, he still does not know how the murderer completed this secret room.

While she was thinking, the sunlight outside the window shone on Ling Yu's face, Ling Yu inadvertently glanced at the window, and suddenly seemed to think of something, and then went out and looked out of the door twice, she smiled. She now fully understands the killer's method of making the secret room.
