"Ah-"At 9 o'clock in the summer morning, a scream full of fear came from Room 20 1 of Building 4 of Tianlan Apartment in a city.
When the police arrived, Wang Keke, a 27-year-old female teacher, was squatting at the door of Room 20/KLOC-0, her eyes were red and her body was still shaking.
According to Wang Keke, a few minutes ago, she knocked on her roommate Chen Xiaolan's door and tried to wake her up. Nobody answered the door. She pushed the door and went in, only to find that Chen Xiaolan was leaning on the bed, with a lot of blood on his head, and dyed the original beige sheets red. She was scared out of her wits and dared not go forward. She flew out of the room and dialed 1 10.
Confirmed by the accompanying forensic doctor, Chen Xiaolan has died.
"Week team, the deceased was hit by a blunt instrument on the back of the head and bled to death. Judging from the condition of the body, the time of death should not exceed fifteen hours, and it is estimated that the time of death is roughly between six and eight last night. Basically rule out suicide. " Forensic Kobayashi reports.
Zhou Zheng, the captain of the Criminal Investigation Brigade, frowned. He turned to Wang Keke and asked, "weren't you at home yesterday?"
"I went out at eight o'clock yesterday morning, went back to my parents' house and came back very late. Wang Keke looked still shaking: "I went home and looked at the clock. It was almost 12, so I didn't want to wake her up. "

Put on gloves, Zhou Zheng went into Chen Xiaolan's room, trying to find some clues.
This is a room of about 15 square meters, which is much messy compared with the average girl's room. The quilt on the bed is casually draped, and the clothes in the closet are stacked layer by layer. Even on the ground, there is a piece of clothes, which is probably going to be washed. In all this confusion, Zhou Zheng found one place unusually neat, that is, the desk by the window. On the desk, laptops, piles of books and pens are neatly arranged, the windows are closed, the green radish on the windowsill seems to have not changed water for a long time, and the leaves have dried up.
Chen Xiaolan was lying on the bed in her pajamas, and her hair was a little messy. Maybe she just took a shower and didn't have time to blow her hair. This shows that when she was killed, although she was wearing pajamas, she was not going to sleep.
03
Wang Keke said that Chen Xiaolan and she are teachers in a middle school. They both teach English.
"What kind of person is she on weekdays?" Geometric asked Wang Keke.
Wang Keke said, "She is cheerful, so she shouldn't do such a stupid thing. Before going out yesterday morning, I saw her humming a tune to choose clothes, saying that she was going to date her boyfriend. "
"Boyfriend?"
Yes, her boyfriend's name is Li Fang, and he is also an English teacher in our school. Wang Keke replied.
Judging from the signs that the gate and door were not damaged and that Chen Xiaolan was wearing pajamas, the murderer was probably an acquaintance.
04
After handling the scene, Chen Xiaolan's parents were contacted and informed, and Zhou Zheng returned to the police station with people. When he found Li Fang's contact information, he immediately called Li Fang and asked him to come to the police station.
Knowing that his girlfriend was killed, Li put tears on the phone: "Will you make a mistake? ! "He said he would arrive as soon as possible.
"You are not in a city?" Zhou Zheng asked.
Li Fang said, "Yes, I came to B yesterday to do something. I slept here last night. I will go back now. "
It's about 2 hours' drive from B city to A city. In the afternoon, Li Fang appeared in the police station, looking haggard.
"Has Chen Xiaolan done anything unusual recently?"
"No", Li Fang shook his head feebly, looking very painful.
"When was the last time you met?"
Li Fang lowered his head and said, "She was still in class when school was over on Friday. I went to the office to find her. "
"Is it convenient to reveal what was said?"
"Nothing," Li Fang paused. "I told her I was going to B this weekend and I couldn't stay with her."
"What's the matter with you going to B?"
"Oh ..." Li Fang looked up and hesitated for a moment. "Can we not talk about this?"
"I'm sorry, in order to understand the situation, I hope you can cooperate," Zhou Zheng stared at him and said.
"I went for an interview. There is a private school over there that wants me to try." Li Fang said, "Oh, but I didn't go in the end. I stayed there all night, thought about it all night, and decided not to go. I don't know ... I shouldn't have gone. I should have stayed with Xiaolan, maybe there wouldn't have been this accident. " He covered his face and his voice began to choke.
Geometric asked several questions, let him go back, Li Fang looked up and stood up, when he left, he took out two bus tickets and a accommodation invoice from his pocket and handed it to Geometric. It's his bus ticket to and from B, a ticket to 1 1 at noon yesterday and a return ticket to 12 at noon today. The accommodation fee is the invoice of X Hotel in B city last night.
05
Seeing off Li Fang, Zhou Zheng had an unspeakable feeling in his heart. He vaguely felt that many details were not quite right.
First of all, Wang Keke said that before going out yesterday morning, he saw Chen Xiaolan picking out clothes and said that he wanted to date his boyfriend, while Li Fang said that he had agreed with Chen Xiaolan to go to B City the next day after school the day before yesterday. One of the two men must be lying.
Secondly, Li Fang's grief-stricken look seems a bit excessive. It is so painful to lose someone you love, but in the end, you suddenly come up with his alibi.
In addition, the unusually neat desk in Chen Xiaolan's room made Zhou Zheng feel not so simple. The green radish is dead, and the table is still so neat?
Chen Xiaolan was wearing pajamas, which showed that the murderer was someone she knew and was defenseless. After investigation, in City A, she has almost no other friends except Wang Keke and Li Fang, and her parents and other relatives are not in this city.
In her mobile phone records, the last one is Wang Keke's phone number, which was at noon yesterday 12. According to Wang Keke, I told Chen Xiaolan that I would be late. The penultimate item is Li Fang's phone number of 10 yesterday morning. According to Li Fang, give her a call before going to B city.
06
For Wang Keke, Zhou Zheng also asked people to investigate. Although her parents are in city A, they don't live together and usually go back on weekends. Going home this week is to help her parents say hello to relatives in the countryside, and relatives and neighbors can testify. After studying at school, Chen Xiaolan and Wang Keke are both colleagues and good friends, which can basically rule out her suspicion.
From this point of view, Li Fang is really the biggest suspect, but he gave an alibi. By retrieving the surveillance video of the bus stops in cities A and B and the X hotel in city B, we did see that Li Fang took these two cars to and from the two cities last night and merged into the X hotel.
After much thought, Zhou Zheng decided to investigate the relationship between Li Fang and Chen Xiaolan first.
After understanding, there is indeed a new situation. According to a classmate in the class, when he passed the school corridor last Thursday, he saw that Mr. Chen and Mr. Fang seemed to be quarreling, and both of them were in a bad mood.
In view of this problem, Zhou Zheng continued to learn from Wang Keke.
"Oh, I remember. Last Thursday night, Xiaolan came home angrily and complained to me that Li Fang didn't trust her and suspected that she was good with other men. " Wang Keke said, "I comforted her, told her not to get angry, and explained to Li Fang. Later, I saw her picking out clothes for a date on Saturday morning, and I was happy for them! "
07
Two days later, Li Fang was invited to the police station again.
This time he looked calm: "Officer, have you made any progress?"
"Have you had any problems with Chen Xiaolan recently?"
Li Fang paused for a moment, then said, "Oh, nothing, just a little argument. This should be normal? "
"It is normal for couples to have some minor conflicts," Zhou Zheng said. "But what if this contradiction has not been reconciled so far?"
"So far?" Li Fang didn't understand Zhou Zheng's intention of saying this sentence.
"Do you suspect that Chen Xiaolan is with someone else behind your back?" Zhou looked at him. "Maybe, I still think so."
"This is not ..."
"This is a postcard from B city", Zhou Zheng interrupted him, "You think she betrayed your love, so you killed her".
"No ..." Li Fang began to worry. He wants to say something, but he can't.
"It's me again! Last Thursday, you went to Chen Xiaolan's office and found a postcard from B city on her desk. You picked it up and looked at it, and found some explicit words written on it. You're angry. You go to Chen Xiaolan and ask her what happened. She said she didn't know who that person was either. Maybe it was a prank. Of course you don't. On Friday, you told her that you would go to B City to confront the man on Saturday. "
Zhou Zheng paused, then said, "You began to regret your attitude after you went back, so you called her to apologize and said that you were not going, and you planned to accompany her to the movies on Saturday. But on Saturday morning, you changed your mind. As long as you think about the existence of that man, you are very angry, so on Saturday morning 10, you called her and told her that you decided to go to B. "
08
Li Fang's expression became very strange.
Zhou Zheng continued: "You went to B to look for the address on the postcard, only to find that it was only the address of a post office. The more you think about it, the angrier you get. As it happens, your mobile phone died, so you called Chen Xiaolan from a public phone booth near the post office. She laughed at your failure. You have a terrible idea in your heart. "
Li Fang covered her ears: "Stop it, no, it's not like this." He began to mumble, "That's not true. I don't want to kill her. "
"In fact, the so-called alibi is very fragile," Zhou Zheng said. "You just want to go back and tell her face to face, so you took a taxi. We later found this car. "
"The next thing, I think you should say it yourself!" The geometry talk stopped.
Li Fang collapsed in the chair, and he didn't argue any more.
09
Last Saturday afternoon, Li made a phone call at the post office phone booth in B city and decided to rush back to A city immediately. He stopped a taxi directly on the side of the road. Back in A city, he went directly to Chen Xiaolan's home. Chen Xiaolan changed her clothes with joy and planned to go on a date in the morning. Unexpectedly, something happened. She sat at her desk, thinking about the postcard. In fact, she knows who it is, a person who has a secret crush for many years, but she swears that there is absolutely no entanglement. What made her angry was Li Fang's distrust.
So, when Li Fang came to her house, they had a fierce argument. In a rage, Li Fang pushed her down. She hit her head hard on the sharp corner of the bed and fell down without even screaming.
Li Fang was scared silly, but he reacted quickly. He carefully changed Chen Xiaolan's skirt and put on her pajamas. He rummaged in his desk for a long time, found the postcard and took it away, clearing the table. He took some large ice cubes out of the refrigerator and put them next to her head to reduce the temperature in the room, then quietly left and took a taxi back to B city.
Li Fang's heart is actually very complicated. Because of an uncertain person and thing, he killed Chen Xiaolan on impulse. Chen Xiaolan died in an elusive ghost. He felt guilty, but he also felt that he was right.
Later, the police found the postcard in his home. He noticed a small line on it: "f hfiiba ebo, f cbbi pl pxa."
Zhou Zheng understood at a glance that it was Caesar's C code, which translated as: "I killed her, and I am so sad."
