Please don't stick to Officer Qi [criminal investigation]

The front desk watched helplessly as Xiao Wang and Tian Wei walked into the room with a lot of tools, using small brushes and searchlights. Those who knew it was a psychological consultation room, but those who didn’t know it thought it was an archaeological site of an emperor’s tomb on site.

But she just said too much, and now she can't go back on her word.She tried to repent, but after being glared at by Qi Lin, she didn't dare to speak anymore, and just stood by and watched.

After a while, Xiao Wang made a discovery.

"Qi team, read this book." Xiao Wang handed a book to Qi Lin, two pages were missing from the book.

Sherlock Holmes, pages 1 to 1 are missing.

"Why, does this have any special meaning?" Shi Le liked "Sherlock Holmes", but he didn't understand Xie Yan's motive for tearing up these two pages.

Qi Lin reads all mystery novels thoroughly.I've seen it on a whim before, but I can't remember it now.He asked Shi Le what was written on these pages.

"It's Scarlet's research. Judging from the context, it should be a record of Watson's memoirs."

When Shi Le said this, Qi Lin remembered.This paragraph is about the continuation of the case, some of Jefferson Hope's performances in the face of the court trial, and additions to events that have not been described.

But it doesn't seem to have anything to do with Xie Yan.

Qi Lin re-observed the tearing of the book.The tearing is uneven, and the paper is frizzy. It is not a vertical tear, but a horizontal tear. Moreover, there is no tool used as a ruler, and the strength is not appropriate. It seems that it was torn off in a hurry.

"Can you roughly know when this paper was torn off?" Qi Lin asked Xiao Wang.

Xiao Wang looked at it for a while, "Not long. It stands to reason that after the paper is torn, the internal fiber structure will slowly oxidize and turn yellow over time, and this paper is very fast, without even a little dirt. It was torn up today. Earlier, not more than a week later."

Qi Lin nodded and continued to examine the two pieces of paper.Generally speaking, for this situation, Qi Lin's first reaction is to check the paper traces on the subsequent pages to see if the key information was written down on the previous page and the information was torn off.But as soon as the words of thanks were torn off, two pages were torn off, obviously noticing this, and deliberately tore off the page with the traces of records, so as to completely cover up the traces.

However, Qi Lin saw that there were also traces on the previous page, which were faint black spots, which looked out of place on the black and white text.

"What do you think this is?" Qi Lin pointed to Xiao Wang.

Xiao Wang looked left and right, and gave the answer, "It's ink."

"Then my guess is right. Xie Yan recorded something on this page, and then tore it up in a hurry. The purpose is still unclear. If he can search his home, there may be more discoveries, but now It's not realistic to get a thorough search warrant just by relying on this." Qi Lin turned his hands away, imagining the evidence that Xie Yan might leave in the room.

Then, Shi Le took the first step, "If there is an appointment form to prove that the people involved in each previous case are related to Xie Yan, can we conduct further searches?"

"It's hard, it's so clean here, it's impossible to keep the reservation form." Qi Lin looked at the front desk, "What do you think?"

"Yes, and there are many people who are personally handled by Mr. Xie, and will not be in my hands."

"Okay." Qi Lin crossed his hips, looked helplessly at Xiao Wang who had already found nothing to investigate, "Let's go, go back to the police station."

……

The search failed, and morale was not very high all afternoon.Sitting in the office, everyone drooped their heads and couldn't lift their spirits.

"Senior, how did you say Xie Yan knew about our plan? We just decided to search on the spur of the moment today, but he just ran away today."

"People can count." Xiao Wang lay on the table, "If he is really the murderer behind the scenes, then his calculation ability is really too strong. If he wants to count the actions of the murderer, the victim and the police at the same time, then he can count It is also reasonable for us to investigate him."

Calculate?

"Are you a fortune teller?" Qi Lin frowned, "All calculations need enough data and information to support them, otherwise, they are no different from fantasy."

"You mean..." Xiao Wang seemed to understand Qi Lin's implication, he lowered his voice, "Is there an internal reaction?"

Qi Lin didn't speak.

This is not the first time he has thought about internal response.But the colleagues around him are very upright, and it's one thing not to rely on it, but it's another thing for the people behind the scenes to actually get the information he needs internally.

The kidnapping of Shi Le in the bombing case, the coincidence handling in the wax figure case, and the transmission of information sources in the sapphire theft case all perfectly avoided the police process. A human relations check also turned up nothing.

It's unreasonable, very unreasonable.

Qi Lin was silent.

Xiao Wang analyzed: "If there is an internal response, then it must be someone who is very close to Xie Yan, but I have never heard of anyone in the police station who has a good relationship with Xie Yan. Moreover, Xie Yan was a consultant in the police station. I don't think he's the murderer."

"The murderer is not the murderer." Qi Lin said, "Besides, because he has been a consultant, he is more suspicious. He has a greater chance to understand the operating mechanism and a greater chance to get acquainted with the police. Insiders."

He paused.

"You said that no one in the police station has a good relationship with Xie Yan - that's wrong, there are still people in the police station who have a close relationship with Xie Yan."

Xiao Wang asked, "What do you mean?"

Qi Lin stopped talking.

"Qi team, you are telling me! Who is that person?" Xiao Wang looked very anxious. He stared at Qi Lin's mouth, hoping to hear Qi Lin's opinion as soon as possible.

But Qi Lin never said it out.

Finally, Shi Le spoke slowly.

"Huang Yuanliang."

"Huang Yuanliang?" Xiao Wang looked at Shi Le in horror, "Impossible, Team Qi, you say it's not true, right?"

Qi Lin still kept his mouth tightly shut, only raised his head to look at Xiao Wang.

Xiao Wang felt his legs go weak for a moment.

Huang Yuanliang can be regarded as his half master, many things were taught by Huang Yuanliang.

Telling him this now, he can't accept it.

"No, it's impossible. Everyone knows what kind of person Lao Huang is, and he even sacrificed for the mission. Team, this is really impossible, it must not be true." Xiao Wang's emotions were pushed back a little. On the verge of losing control, the calm questioning gradually became hysterical.

Qi Lin felt distressed seeing Xiao Wang like this, but he had no choice but to look at him quietly, then raised his index finger and put it between his lips.

"Shh-"
