At this time, Ling Yu held in his hand the clues that were crucial to this secret room technique, but there were still many clues that had not been discovered, and it was not yet the time to reveal the secret room technique. She first had to be clear about one thing. That is, the murderer knew that this phenomenon at the scene of the murder could easily be identified as homicide, so why did he hold the murder weapon in the hands of the deceased, and went to great lengths to make a secret room. The phenomenon of intentionally causing the deceased to commit suicide in a closed room.

After putting away the two items she had just found, Ling Yu walked around the deceased's body, as if asking for something. She called Shu Xiaoran, and Shu Xiaoran mentioned on the phone that there were a small amount of chemicals in the deceased's body, and she asked Shu Xiaoran to check the position of the deceased's hands with reagents to see if there were chemicals similar to those in his body.

Shu Xiaoran put down his backpack, took out the items for laboratory testing, and after applying some medicine on the palm of the deceased's hand with a cotton ball stick, he took out another part of the reagent for measurement, and after just a few minutes, Shu Xiaoran got up and said to Ling Yu behind him:

"Boss, the deceased didn't have any chemicals on his hands."

After listening to Shu Xiaoran's answer, Ling Yu seemed to have gotten the answer she wanted:

"And so it was!"

Although Shu Xiaoran was a little skeptical, he didn't dare to be 100% sure: "Could it be that this is a case of homicide in a secret room?" ”

"Let me ask you, if Robert really committed suicide, then since he has some drugs in his body, how can his hands be so clean, and it is very strange that you have found it, there is only the fingerprint of the deceased on the murder weapon, and this knife has been proved to be the deceased's home utensils, in this case, the deceased will generally not touch it, it is used by the subordinate or the housekeeper, even if it is used occasionally, it will not be as clean as it is now, and only the deceased is left alone." Ling Yu replied to Shu Xiaoran.

"There's only one possibility." Shu Xiaoran seemed to have understood something.

Ling Yu could see that Shu Xiaoran understood what he meant: "It's the same as you think, unless the murderer used it to kill someone and disposed of all the fingerprints on it before putting it on the deceased's hands." ”

When the two of them were talking, Chu Ming seemed to have discovered some clues:

"Boss, Xiao Ran, you come here!"

Ling Yu and Shu Xiaoran looked in the direction of the sound, and found that next to the bookshelf facing the door of the study, Chu Ming was standing there, and after a while, the two came to Chu Ming's side, and Xiao Ran said, "What's wrong Chu Ming?" What did you find? ”

Chu Ming stretched out his hand and held a document in his hand, because the text on it was still facing away from the two of them, so Xiao Ran and Ling Yu didn't know what Chu Ming was holding in his hand.

"What is this?" Ling Yu asked him.

"This is a document for Robert's latest opera, and I think we might use that."

"What else?" Xiao Ran then asked.

"And this!" Chu Ming said as he raised his other hand, holding a key in his hand, which looked like it should be the key to the study. It is now more certain that the killer was deliberately creating a locked room murder. Because there are no traces of fingerprints on the key, including the deceased.

"It's just that I still don't understand, how did the murderer lock the door and then move it to this place?" Chu Ming didn't understand.

Ling Yu said to Chu Ming: "Regarding this question, I will answer you later, the question to be solved now is how the murderer entered Robert's house, Chu Ming You took pictures of some parts of the deceased's body, especially the place where the knife was cut, Xiao Ran, you go and call the housekeeper in Robert's house, we may get some relevant information from his mouth." Ling Yu looked at Shu Xiaoran.

"Okay!" Chu Ming and Shu Xiaoran answered almost at the same time.

After speaking, Chu Ming stayed with the deceased to collect evidence, and Ling Yu and Shu Xiaoran walked out of this study.

In another room, Xiao Ran called the housekeeper in Robert's house, that is, the first person to find Robert's body, there were only Shu Xiaoran and Ling Yu in the room at this time, pushed open the door, and what they saw was a middle-aged woman, who looked like she was over forty years old, with a lot of white hair in her temples, but fortunately, her hair was still shiny, her face was not wrinkled, she was slightly fat, and she was wearing the work clothes she usually wore when she worked at Robert's house.

It can be seen that the treatment of this person in Robert's house is still good, but when he first came in, the housekeeper's face showed some panicked looks.

"You don't have to be nervous, we just want to find out what happened at Robert's house last night." Ling Yu said to the middle-aged woman.

"Uh-huh, two police officers, I will do my best to cooperate with your investigation." The middle-aged woman replied.

Ling Yu asked the woman if anything strange had happened at Robert's house last night, so that it was only this morning that she found out that Robert had been killed.

But what they didn't expect was that the butler's answer was almost of little help to the two:

"I wasn't at Mr. Robert's house last night."

How can this be, according to common sense, a housekeeper like Robert's house, except for weekends and holidays throughout the year, almost all of the food and accommodation are carried out in the master's home, but according to the clues that I have before, last night should not be the time for the housekeeper to take a vacation.

"Where have you been?" Shu Xiaoran asked this person.

"I'm home." The middle-aged woman replied.

"However, last night was not the time for you to take a vacation, so why didn't you stay at Robert's house," Ling Yu asked.

The middle-aged woman replied: "Indeed, as usual, I should have stayed at Mr. Robert's house last night, but you may not know that Mr. Robert has a habit that every time he wants to write a new opera, he likes to be alone in the study, and not only that, he does not allow anyone in the house, so last night, not only me, but all the people in the family went home, and last night my child was going to tutor, and I happened to ask the child's tutor about the child's recent learning." ”

In other words, the middle-aged woman in front of her has an alibi.

Seeing that the middle-aged woman didn't look like she was lying, she originally wanted to ask some clues about the murderer from the housekeeper's mouth, but in this way, there should be only Robert in Robert's house last night, and it is easy for the murderer to sneak in, this is far away from the residential area of Chengguang City, probably because Robert didn't like the bustling sound when he wrote the opera, but it is precisely because the area here is relatively remote, so even if the murderer sneaked in to kill Robert last night, it is estimated that no one will find traces of the murderer.

After asking a few words, Ling Yu asked the woman to leave the room, but I am afraid that from today onwards, Robert's home will be blocked, and it also means that the woman will lose her job just now, in the current society, there is no job, and I don't know how the woman will live next.

The evidence at the scene was almost searched, and Chu Ming also took a lot of photos, and then, after getting the permission of their superiors, Ling Yu and others took Robert's body back to the autopsy room and asked Shu Xiaoran to do further laboratory investigation.

Subsequently, all police forces withdrew from the area, and the cordon was raised again, sealing off the entire luxurious villa within the cordon.

【Chengguang City Public Security Bureau】

According to the situation that Fang had just discovered at Robert's house, Ling Yu and others began to analyze it. There is one thing they must first figure out whether there is a connection between Robert's case and Tang Hong and Gao Bin's two cases, and whether it will be done by the same person.

While discussing, Shu Xiaoran seemed to hear something, and took off his mask while walking out of the autopsy room: "Robert's case and the previous two cases were not done by one person!" ”

Hearing Shu Xiaoran's voice, Chu Ming and Ling Yu looked in the direction of the autopsy room:

"Are you sure?" Ling Yu asked.

"Boss, you should have been sure of Robert's wounds when you saw him at his house." Shu Xiaoran replied.

Ling Yu smiled, it seems that Shu Xiaoran was right, when he saw his body at Robert's house before, Ling Yu observed that the wound on his throat was cut very unevenly by a knife, it seemed that the murderer was very hard when cutting, but there was no way to cut it to the end, presumably the murderer was very panicked when cutting his wound, just like the first time he committed a crime, the cut was very sloppy, not like the wound on Tang Hong's body, almost a knife was flat to the end, and he was completely in a state of enjoyment. The reason why Ling Yu further confirmed to Shu Xiaoran was because, according to his previous speculation, the next deceased was very likely to be Liu Xuan, but it was Robert, and his death appeared at this time, which felt both timely and untimely, both coincidental and uncoincidental.

What is now certain is that the murderer of Robert and the murderer of Tang Hong Gaobin are not the same person, but if there is a connection between this case and the previous two cases, what will this invisible connection be? And what will be the relationship between the two murderers? Regardless of whether there is a connection between these cases, the situation has become more and more complicated, and none of the cases have been completely resolved. In the case of Qin Jian's disappearance, the original mysterious person had not yet revealed relevant clues, and the second mysterious person appeared again.

After the incomplete wound was finished, Shu Xiaoran continued: "Another point, the drug found in Robert's body has never appeared on the market, it should be a homemade drug, this drug has no lethal effect, it can be transmitted through the air, and the human body will play a role in a short period of time after inhalation, making people sleepy, the murderer should first make Robert fall into a coma through drugs, and then cut the throat of the deceased with a knife in the deceased's home, and after processing the fingerprints on it, put it in the hands of the deceased, Then the chamber was made. ”

"According to the practice report, the time of death of the deceased was about 9 o'clock in the evening on July 20." Xiao Ran added.

"What are you thinking?" After Xiao Ran finished speaking, Ling Yu saw that Chu Ming had not spoken.

"How much resentment do you say the murderer has towards the deceased?" Chu Ming was holding a photo in his hand.

"What did you say?" Ling Yu said as he walked up to Chu Ming, who was holding a close-up of the wound on the deceased's throat.

Chu Ming then replied: "You also said just now, the wound cut by the murderer is very incomplete, it seems that he can't use force, but he also uses all his strength, and when he cuts each knife, it seems that he is getting something back from the deceased, when he was investigating the deceased before, a record of him was erased when he was about thirty years old, maybe it happened at that time." ”

After Chu Ming finished speaking, Ling Yu then looked at the photo, if he thought about it, Chu Ming's speculation was not impossible, in the photo, the document pressed under the deceased's head should be his latest opera, but I'm afraid that this opera will never have a chance to be staged again.

"By the way, you seem to have seen how the murderer made the secret room when he was in his home." Ask Ling Yu.

Ling Yu took out two items from his pocket that he had found in the deceased's house before, and Chu Ming and Shu Xiaoran saw that one was a fishing line and the other was an iron nail. After placing the two items on the table, Ling Yu began to recreate the process of making the secret room.

For a long time, Chu Ming and others have had a misunderstanding, that is, how did the murderer lock the door and then hide the key in the bookshelf, which seems almost impossible. But the murderer took advantage of this to deceive Chu Ming, in fact, the murderer had hidden the key in the bookshelf before leaving the study, and the door of the study was not locked at all. Ling Yu had previously observed that the handle of the door was pressed down, and if there was a force to support the handle from being pressed down, the door would not be opened, and when the door was opened from the outside, it would give the illusion that the door was locked from the inside.

And to achieve this, fishing lines and nails are the key things.

After killing someone, the murderer fastened the iron nail to the top of the door, then left the study and closed the door. Ling Yu observed that the door was very close to the window on the right side, whether it was outside the study or inside the study, there were windows, the murderer should have used objects such as remote-controlled airplanes, equipped with camera devices, and then folded the fishing line from end to end, tied the head and tail to form a coil, put a section of it on one end of the remote-controlled aircraft, moved the plane from the window outside the study through the window in the study to the study, and used the camera device to put the other end of the fishing coil on the downward pressure handle. Complete the crafting of the Chamber of Secrets.

When I entered the study before, I saw that the windows in the study were open, and I thought it was because I wanted to get out of the room as soon as possible, but now it seems that it should be to let the plane enter the study smoothly.

The secret room and the murder method have been solved, but the clues about the murderer have not been solved. Although it was not one person who killed Robert and Tang Hong Gaobin, Ling Yu always felt that there was some hidden connection between the two. It's like she always thought that, according to the plot of the movie, the third deceased would be a novelist, not an operator.

After describing the techniques of the secret room, Ling Yu looked at Chu Ming, and the expression on Chu Ming's face was a little inexplicably panicked, as if he wanted to say something they had been looking forward to.

"Chu Ming, what do you want to say?" Ling Yu asked.

"After you just talked about the secret room, and then I thought about the identity of the deceased's cause of death, which made me think of a person!" Chu Ming's pupils widened and he looked at Ling Yu.

Ling Yu rarely saw Chu Ming like this: "Who?" ”

"Liu! High! Chu Ming said Liu Xuan's name almost word by word.

"What does this have to do with Liu Xuan?" Shu Xiaoran asked Chu Ming.

Chu Ming replied: "When I went to Liu Xuan's house with Qin Jian to inquire about him before, I read his new book "Blood Rose", and after the secret room described by the leader just now, the identity of the deceased is exactly the same as the identity of the deceased in his novel, and even the cause of death is the same, he was also cut throat and died in the secret room!" ”

In this way, the third deceased is still related to the novelist, although the deceased was not a novelist, but he did die according to the novelist's novel! Then this murderer must have something to do with the murderer who killed Tang Hong and Gao Bin, and even with the personal information that Robert was erased when he was about thirty years old.

After all, it was too much coincidence that Robert was murdered at this time, and it happened to be killed according to Liu Xuan's novel "Blood Rose". There must be some crucial reason in the middle. And I don't know if there will be the next deceased, if so, who will be the next deceased, and on what basis did the crime be committed, at the moment there is no news from Qin Jian, and the mysteries pop up one after another.

Now maybe Ling Yu already knows why it is easy to see why he killed him, and the murderer still has to go to great lengths to make a secret room, and his purpose should be to tell Ling Yu and others that he is committing a crime according to Liu Xuan's novel "Blood Rose". If this hypothesis is true, there must be some relationship between Robert's death and the first two deceased, but this relationship is too secret to be discovered. There is also the question of what is the relationship between the two murderers.

From Robert's wounds, it can be seen that the murderer has a lot of hatred for Robert, what is this mystery? Ling Yu asked Chu Ming to investigate the personal information about Robert around the age of thirty as soon as possible. From this, you will definitely be able to find clues to the murderer.

"Okay, though, this is a bit difficult for me at the moment, I have to contact my master!" Chu Ming replied by holding his glasses.

Regarding the information about Chu Ming's master, even the police have not had a detailed file, this person is extremely mysterious, in today's world, it is estimated that only Chu Ming knows. A mysterious person has not yet been solved, and a second mysterious person has emerged. The immediate thing to do now is to find out what the real connection is in several cases.

originally thought that the connection between the cases was only the movie "The Entrance to Heaven", but what I didn't expect was that "Blood Rose" was actually implicated, and if I didn't find out what the real connection was, I was afraid that the next victim would appear.
