The detectives knocked on the door, and they brought the latest news, about the books found in the quarters of the four deceased. The detective was followed by a number of people, dressed simply, carrying a bag of marijuana on their shoulders, who they said they had brought back from near the police academy.

The criminal police centered around the police academy and spread outward, searching from early morning until late at night, Wen Ning focused the case on the source of those books, so he spent a large number of police forces on this. The detectives brought back seven or eight people, who, according to the detectives, were brought back from under the overpass.

City B has strict security supervision and often cracks down, so there are very few roadside stalls on the streets, and only under some remote overpasses will there be some people selling books without print numbers and illegal CDs. These people looked at us with horror on their faces.

Wen Ning asked them to put down the sack they were carrying on their shoulders, no one dared to be disobedient, and after putting down the sack, Wen Ning personally went to pour all the books inside on the ground. Each sack contains dozens of books, and the books are not thick, but so many books together, and then on the shoulders, it is enough to make people tired.

These book sellers were sweating profusely, and their clothes were sticking to their skin, Wen Ning was quite humane, let them go to the place where the electric fan was blowing to cool down first, and he flipped through them one by one. I didn't go to read the books with Wen Ning, but set my eyes on the group of people first.

Among them, a few were older and had gray hair, and a few were young people but dressed poorly. Sensing my gaze, they looked at me and immediately looked away. They didn't dare to look at anyone in the office, and although the wind was blowing, the sweat on their faces kept dripping down.

When a criminal police officer asked them why they wanted to sell these books, they said that they just wanted to make some money, but they couldn't afford to open a store, and they got these books cheaply through various illegal means. They begged the detectives to let them go, claiming that they couldn't sell much either, and that a book only sold for three or four yuan.

In particular, a few elderly people said that they were miserable, saying that there were sick and disabled people in the family, and there were young children waiting for them to raise. Someone said this, and suddenly they all got together, and one said worse than the other, and the cacophony echoed throughout the small office.

Wen Ning was upset when he heard this, and cursed fiercely, and suddenly, these people didn't dare to speak again. Judging by their mannerisms and demeanors, I couldn't tell that there was anything wrong with any of them, so I walked over to Wen Ning and crouched down and flipped through the books with him. There are a lot of illegal books, most of them are obscene books, Wen Ning refused to let go of every page of each book, and asked a few criminal police officers to help to see if they could find the clip in the book.

One book after another was excluded by Wen Ning and everyone, because of the relationship of time, the criminal police who went to investigate didn't have time to open those books at the scene, and directly brought all the people back. Soon, a criminal police officer said that he had found a strange book, and when he opened it, it was indeed a book about various so-called ghost methods.

Wen Ning picked up the book and asked sharply whose it was, an elderly man trembled and said that the book was his. Wen Ning was about to continue the interrogation, when another criminal police found similar books, and then the criminal police found dozens of similar books among the books poured out of seven or eight sacks.

Through inquiry, everyone brought back by the criminal police sold such books. Wen Ning had a headache and asked them if they knew what they were selling, and some people shook their heads, saying that they were illiterate at all, and if they were literate, they would not come out to do this, but would go to find a good job.

Wen Ning sent a few criminal police officers to interrogate these people one by one, and he continued to check the dozens of books. The covers of the books are all different, but the content of the records is similar, the most obvious is that each book records the game method of inviting the pen fairy.

Soon, the results of the interrogation came out, and in order to determine whether these people were suspected of committing crimes, Wen Ning sent many people to find the families of these people according to the confessions of these people. When I looked at the interrogation transcripts, I found a similarity: the books sold by these people came from a variety of sources, and the prices were also different, but those books related to this case were all purchased at very cheap prices, some even only a dime or two, and after bargaining, the books were even a few dimes a dime.

Most of the time, individual vendors have come to these flyovers and ask if they want books. There are no cameras under those overpasses, and it's not easy to find the earliest sources of these books.

The criminal police were busy for several days, exhausted, and some of the vendors could not even speak Mandarin, so it was very difficult to interrogate, and the criminal police were inevitably upset when the weather was hot. Many criminal police officers felt that they couldn't ask anything, so they didn't continue to ask. It wasn't just me who found out about this problem, Wen Ning read the interrogation transcript and immediately got angry.

I felt that Wen Ning was also a little anxious, and reminded him in a low voice, Wen Ning took a deep breath and let all the criminal police sit around the desk, and he personally interrogated. Wen Ning was experienced, and as soon as he opened his mouth, he grasped the crux of the matter, and he asked those people how they got the ghost book.

There are seven or eight people here, and even if one person forgets, it is impossible for everyone to forget all of them. Whether we can find the source of the ghost book remains to be said, but if we ask, we can at least narrow down the scope of the next search. As I expected, many people couldn't remember, but a few vaguely said that it was a young man who sold it to them.

Wen Ning nodded, letting them continue one by one. Under the reminder of those people, the others also remembered one after another, and they said that those ghost books did seem to be sold to them by a young man. They don't remember the time, but it was about a month ago that the guy carried a lot of books on the subject and gave them them at a very cheap price.

They were so happy that they took it without even thinking about it. As for the young man's appearance, they don't remember either, only that he probably has short hair, and he is neither tall nor short. Wen Ning glanced at me, and I nodded at him, and Wen Ning repeated it, asking if they were lying.

Everyone shook their heads in horror and said they didn't dare to lie.

"It's not legal for you to sell this kind of book, but it's not under our control, this matter is very important to the police, if you think about it carefully, if you make a meritorious service, I can find someone to reduce or reduce the punishment for you." Wen Ning's words made everyone happy, but Wen Ning added: "But if anyone dares to lie, the police can define you as an accomplice to the criminal, and you will be imprisoned!" ”

Wen Ning spoke very politely, I didn't have much contact with him, but his words made me admire him slightly. He has a good grasp of the psychology of the interrogation subject, which not only allows everyone to try to recall, but also avoids the possibility of everyone's casual nonsense.

Everyone lowered their heads and thought about it for a long time, and in the end, everyone was sure that what they had just said was true, and they didn't add any more questions. They stayed in the house for a whole afternoon, and it was not until the criminal police who went to these people's homes came back that Wen Ning contacted the public security police in this area to take these people away, and explained that they must take care of these people, these people may be important witnesses, and may even be criminal suspects.

The criminal police questioned the families and neighbors of these people in detail, and these people had lived in City B for a long time and had no criminal records. After the person left, Wen Ning asked me what I thought.

"The source of these ghost books is more suspicious, think about it, sell books to street vendors, and even sell a few copies to them for a dime, is it to make money?" I asked rhetorically.

Wen Ning nodded: "Maybe it's just to avoid suspicion and deliberately go through the form, but he is afraid that these books will not be sold in the hands of these hawkers, and maybe because he is in a hurry, he has no time to bargain, so he directly sold them to the hawkers at such a low price." ”

Another detective interjected, and according to the peddler's description, the person who sold them the ghost book was probably the same person, and it was a young guy. Speaking of this, everyone frowned again, everyone didn't remember what that person looked like, and there were no surveillance cameras, how could the police find the person who really sold ghost books.
