When I got the news, Jiang Jun and I were in the appraisal department, and Jiang Jun handed over the painting he brought back from Zhou Xiaoruo's house to the appraisal staff. The people in the forensic department were busy, and the bloodstains, traces, and Zhou Xiaoruo's autopsy report obtained from the crime scene were only preliminary conclusions, and further identification was needed before a final definitive conclusion could be drawn.

On the way back, we passed by Wang Xin's office, but Wang Xin didn't know where he had gone. So we rushed to the officer's office, where the people watching the surveillance video were still sitting and stood up with some excitement when they saw us coming.

They said that a few days before Zhou Xiaoruo's crime, every day at about 6 o'clock in the afternoon, a man and a woman would knock on the door of Zhou Xiaoruo's house with a small box. Sure enough, at 6:01 p.m. three days before Zhou Xiaoruo's disappearance, a couple of people came to the door of Zhou Xiaoruo's room.

Their age is not discernible from the surveillance footage, they are holding hands, and the man is carrying a small suitcase. There is also a child next to them, compared to the height, the child is probably a teenager, what I pay attention to is that the child is wearing a school uniform of the same color as Zhou Xiaoruo.

They kept knocking on the door, but no one came to open it. A criminal policeman told me that at this time, Zhou Sheng and his wife had not gone back, but Zhou Xiaoruo had already gone home, but I don't know why, Zhou Xiaoruo did not come out to open the door. The man and woman knocked on the door for about two minutes, and finally they didn't know what to say to each other, so they went down the hallway.

The entrance to the corridor where they had gone was the one where there was no electric light, and after about fifteen seconds, they went back around and went down the other side. Next, the criminal police showed us the surveillance camera of Zhou Xiaoruo two days before his disappearance, and the three people would still knock on the door of Zhou Xiaoruo's house at about the same time, but Zhou Xiaoruo still did not open the door, although he was at home.

"There's something wrong with this man and a woman." Jiang Jun immediately concluded.

I shook my head: "Not necessarily, find out who they are first." Ask Zhou Sheng to go again, looking at their appearance, it seems that they are here to find someone, maybe they know each other. ”

Jiang Jun went to find Zhou Sheng again, I looked at my watch, it was more than eight o'clock in the evening, and before I knew it, the day was about to pass. It was already dark outside, but everyone was working overtime.

Soon, Jiang Jun once again brought Zhou Sheng here. After Zhou Sheng came back, he went to the police lounge to take care of Zhou Xiaoruo's mother, and when he came back, his eyes were red and swollen, and it was obvious that he had just cried.

There was not much time, I went straight to the point and asked who the three people on the surveillance screen were, Zhou Sheng was short-sighted, he squinted his eyes for a long time, and then told us that the man was his brother, and he asked their family to bring food to Zhou Xiaoruo.

"Deliver food?" I asked.

Zhou Sheng nodded, he told us that Zhou Xiaoruo had inadvertently complained about them before he disappeared, saying that eating late every day would affect his studies. It was a critical period for Zhou Xiaoruo's education, Zhou Sheng discussed with Zhou Xiaoruo's mother, and after preparing to work for a few more days, he would go back to accompany Zhou Xiaoruo as soon as possible, so he asked his brother to send Zhou Xiaoruo a few days of food first, so as not to complain again.

But Zhou Xiaoruo just didn't open the door, and after three days, Zhou Sheng still decided to end his overtime early and go home to accompany Zhou Xiaoruo. But when he got home that night, Zhou Xiaoruo was gone.

"Does Zhou Xiaoruo have a bad relationship with your brother's family?" I asked.

Zhou Sheng denied it. Zhou Sheng's brother's name is Zhou Guang, and he lives in a community with them, according to Zhou Sheng, the relationship between the two families has always been very good, and Zhou Xiaoruo will go to their house to play on weekends. After asking, Zhou Sheng went down.

"That sounds like a good idea." Jiang Jun was a little frustrated, he finally found a more suspicious person, but he didn't expect it to be Zhou Sheng's brother's family, and it was Zhou Sheng who asked them to send food to Zhou Xiaoruo.

I asked Jiang Jun to invite Zhou Guang's family, Jiang Jun was puzzled, I asked him rhetorically, he lives in a community, does it take a family of three to deliver food for three consecutive days. Jiang Jun reacted and immediately asked people to find Zhou Guang.

At the same time, the three squads that had gone out to check returned. They searched outside the community and near Shihua Middle School for several hours, and there were people coming and going, and no one noticed whether Zhou Xiaoruo had passed by that day, and the security guards of Shihua Middle School did not find that Zhou Xiaoruo had returned to school on the night of his disappearance.

And on the hillside where Zhou Xiaoruo's body was found, there was no one, and they couldn't find anyone if they wanted to ask.

Knowing the general situation, we returned to Wang Xin's office, Wang Xin had already returned, and he was sitting at his desk, bowing his head and writing something. Jiang Jun called Wang Xin, and Wang Xin immediately took the book to cover the words he wrote. Xu Yi and I looked at each other, and we both felt that Wang Xin seemed to have something to hide from Jiang Jun.

Wang Xin stood up with a smile, Jiang Jun asked him where he had just gone, and Wang Xin said that the corps temporarily called him to a meeting.

Before Jiang Jun could ask in detail, Wang Xin sent him out, saying that he had something very important to say to me. Jiang Jun glanced at me and walked out obediently.

After the office door closed, Wang Xin let out a long sigh, which was somewhat contrary to his previous calm performance.

"Captain Wang, what are you writing?" I asked.

Wang Xin walked to the table and picked up a page of letterhead paper that he pressed under the book, on which he wrote a paragraph with a fountain pen, and the title of this paragraph was four words: resignation application.

I frowned: "Captain Wang, do you really think I can't solve this case, so I even wrote my resignation letter in advance?" ”

Wang Xin did not answer my question, but told me that the corps had put pressure on him again, and that a day had passed, and there were only six days left before the deadline for Wang Xin's "military order". When Wang Xin said this, he took out a pack of cigarettes from his pocket, which was new and had not been opened. He opened the cigarette case, pulled out two cigarettes from it, and handed me one.

I took the cigarette and he lit it for me himself, and I noticed that even the lighter was new.

Wang Xin lit the one in his mouth again, and after taking a deep breath, Wang Xin staggered back, but he still held on to the table and stood firm.

"I've been quitting this thing for more than ten years, and I haven't smoked it for too long, and I get dizzy when I tap it." Wang Xin laughed self-deprecatingly.

Wang Xin had something to say, I heard it, but I didn't ask, I smoked quietly, I knew that he would definitely speak again. Xu Yi sat on the side, the smell of smoke quickly filled the entire office, and after smoking a cigarette, Wang Xin really spoke again, and he snuffed out the cigarette.

"Professor Li is really patient, there are very few young people like you." Wang Xin stopped beating around the bush anymore, and he continued to say to me: "Professor Li, many things, like this smoking addiction, have been buried for a long time, but once they are discovered, they are out of control. ”

"Captain Wang, please forgive me for not being able to speak, I don't like people to follow me, and the matter between you and Jiang Jun actually has nothing to do with me. And, even if he follows me, he will find out one day. "Once again, I rejected Wang Xin's request.

Wang Xin shook the resignation letter in his hand again and answered the previous question I asked. He said he would resign regardless of whether the case could be solved or not. It was he who brought Jiang Jun to the road of the police, and he originally thought that Jiang Jun would become a policeman, and maybe he could atone for Jiang Jun's father.

Wang Xin said that he had no way to continue on this road, and that he wanted to resign, but he didn't want Jiang Jun to know.

"Can't go on?" I don't understand what Wang Xin said, many criminal policemen have spent a lifetime and can't get to Wang Xin's position, but he told me that he can't go on.

Wang Xin was reluctant to give a reason, and he begged me again to let Jiang Jun follow me. I wanted to say no more, but Wang Xin suddenly said something that made my heart beat violently.

"Your unsolved case may need Jiang Jun." Wang Xin said.

I narrowed my eyes, for so many years, the cases I have intervened in, the cases that have not solved or even a little clue, only 330 cases, what he said, is it 330 cases?
