"Nothing. It's just that I'm not feeling well, so I asked for leave to rest. Anyway, the classes of the third semester are almost over, so I don't think it will have much impact. ”

"Did you go to the hospital?"

"No, it's not that serious, so I can be at school in the afternoon."

"I've heard that you've been studying mathematics for a long time, and you often stay up all night. So according to the dean, at times like this, you take time off the next morning. ”

"I remember explaining that to the dean."

"I've heard that this frequency is about once a month," Tian Chunda lowered his eyes again to look at the attendance schedule. "The day before the eleventh, on the tenth, you took a leave of absence in the morning. Because it was a common practice, the dean didn't think about it, but when he learned that you were taking a leave of absence the next day, the dean seemed a little surprised. It seems like an unprecedented phenomenon for you to take two days off work in a row. ”

"Unprecedented...... Will it? Shi Lei propped his forehead, this situation must be answered cautiously. Actually, there is no great reason. As you said, on the 10th, I didn't come to school until the afternoon because I stayed up late the night before. As a result, I had a fever that night, so I had to take a leave of absence the next morning. ”

"That's why you're only coming to school in the afternoon?"

"Yes."

"I see." Tian Chunda looked back at him with obvious suspicion.

"What's so strange?"

"No, I'm just thinking that if you can come to school in the afternoon, it means that you are not feeling well, but it should not be serious. However, if it is a minor illness, I should usually be able to get up and go to work as usual, so I am a little curious. After all, you've already taken half a day off the previous morning. Tian Chunda bluntly expressed his suspicions about Shi Lei. It's probably out of the way, even if he annoys Shi Lei because of this, he doesn't care.

Do you think I'm going to fall for your agitation? Shi Lei smiled wryly.

"I might have heard you say that, but I was so uncomfortable that I couldn't get up. But when it was almost noon, I suddenly felt better, so I pulled myself together and went to work. Of course, as you said, it's also because I was embarrassed to take a leave of absence the day before. ”

When Shi Lei spoke, Tian Chunda kept staring at his eyes with the kind of sharp and stubborn gaze that firmly believed that the suspect would be embarrassed when he lied.

"That's right, since you're usually practicing martial arts, you must be fine after a half-day rest if you have a little problem. The director of teaching also said that he had never heard of Teacher Shi Lei being sick. ”

"No, of course I'll catch a cold too."

"You mean, it just happened to be that day?"

"What does 'coincidence' mean? It was nothing special for me that day. ”

"That's right." Tian Chunda covered the attendance sheet, got up and said, "I'm really sorry that you're so busy and bothering." ”

"I'm embarrassed to not help."

"Where, that's enough."

About an hour after the criminal police left, Shi Lei came to a public phone booth not far from his home. After carefully observing that no one was watching, he walked into the phone booth and picked up the microphone.

"Hey, I'm Liu Jing." The other party's voice was heard.

"Is it convenient to speak now?" Shi Lei asked.

"Convenient."

"What's new today?"

"When I got home from work today, the police followed, and it seemed that they were waiting for me to come back at the door."

"What did the police ask you?"

"He asked me about the movie I watched that day, and I took the movie ticket stub, saying that I wanted to use it for further investigation. The police also checked the wires of the appliances in my home. And asked me if I had any extra wires stored at home. But it doesn't seem to have found any problems. ”

"The police are now investigating more and more deeply, so you should pay special attention."

"I see."

After putting down the microphone, Shi Lei thought, fortunately, the wire used to strangle Zhang Fu was replaced, otherwise the police would really find out the problem. He also thought that the police would probably find out the problem by taking the movie ticket stub away and investigating it. Because the ticket stub was forged by himself using computer mapping software. Although it can be almost chaotic, it is necessary to carefully use new technological means to check, and problems will be discovered. So what to do? It seems that I can't carry it anymore, in order to protect Liu Jing's mother and daughter, I have to break the boat!

So that night, Shi Lei made an arrangement to break the kettle.

10

The next day, Shi Lei came to the Municipal Criminal Investigation Detachment to surrender.

He said to Tian Chunda: "Zhang Fu was killed by me, and I surrendered myself." ”

"Then tell me about the crime." Tian Chunda looked at Shi Lei and said.

"The first time I saw that person was on March 10." Shi Lei began the narrative in a flat voice, "As soon as I returned to the apartment from school, I saw the man circling next to the house. seemed to be looking for Liu Jing's house, and reached out to dig through the mailbox on her door. ”

In the interrogation room, there are Tian Chunda and Hao Dong, and Hao Dong is taking notes at the next table. Shi Lei refused to be accompanied by other criminal police. His reasoning is that if there are too many people scrambling to ask questions, he will not be able to organize his thoughts.

"The man you're talking about is Zhang Fu, right?" Tian Chunda asked.

"Yes, I didn't know him at the time. I thought it was strange, so I called out to him and asked him who he was looking for. He panicked, saying that he was looking for Liu Jing, and that he was her estranged husband. I knew right away that he was lying. But in order to let him down, I pretended to believe him. ”

"Wait a minute, why do you think he's lying?" Tian Chunda questioned.

Shi Lei took a small breath. "Because I know Liu Jing well. Including that she is divorced and is hiding from her ex-husband, I know all these things. ”

"How do you know so much? Although you live next door to her, I've heard that you rarely speak, and that you just frequented the restaurant where she worked. ”

"That's on the surface."

"On the surface? What do you mean? ”

Shi Lei straightened his waist and puffed up his chest slightly.

"Liu Jing asked my neighbor, who knows martial arts, to be her personal bodyguard. It is my duty to keep her out of the men who are trying to get close to her and protect her. But I don't really want people in society to know about it. After all, I'm still a high school teacher. ”

"That's why the first time I visited, you told me that you barely had any contact?" Tian Chunda asked, and Shi Lei exhaled slightly.

"You came to me to inquire about Zhang Fu's murder, right? Then how can I tell you the truth. Otherwise, you will be immediately suspected. ”

Tian Chunda nodded, "You just said that because you are a personal bodyguard, you know Liu Jing well." ”

"Yes."

"In other words, you've been in close contact with her before?"

"Yes, I want to stress again that this is a secret affair hidden from the world. Although she had a daughter, we kept the child a secret and kept in touch carefully and skillfully. ”

"Can you be more specific?"

"We have a lot of contacts, would you like to elaborate on them?" Shi Lei showed a snooping look.

Tian Chunda thought about it and still felt that something was wrong. Shi Lei's claim that he had secret contact with Liu Jing is too abrupt, and the background is ambiguous. However, for Tian Chunda, he just wants to find out the truth of the case as soon as possible.

"I'll find out about this later, and you can describe your conversation with Zhang Fu in detail. As you mentioned just now, you decided to pretend to believe that he was Liu Jing's husband for the time being......"

"He asked me if I knew where Liu Jing had gone. So I said: she doesn't live here now, and it seems that she had to move because of work, so she moved out not long ago. He was amazed. Then she asked me if I knew where she lived now, and I said yes. ”

"Where did you tell him?"

Hearing Tian Chunda ask, Shi Lei smiled coldly.

"I told him to move to an apartment near the sewage treatment plant."

This is where the sewage treatment plant appeared, Tian Chunda thought.

"But he can't find it just by saying that, right?"

Of course, Zhang Fu was anxious to know the detailed address. I told him to wait outside, and he went into the house by himself, and while looking at the map, he copied his address on a note paper. The address, which is located near the sewage treatment plant. As soon as I gave him the note, the idiot was overjoyed and said I had helped a lot. ”

"Why would you make up the address of that kind of place?"

"That's of course to trick him into a sparsely populated area, and I've always been familiar with the geography of the sewage treatment plant."
