heart poison

"Man Xiaocheng?" Shen Nonghan was different from most of the people who were invited to the inquiry room. He was so calm and unhurried, with no tension on his face, not even surprise or anger, as if he came to the police station from the campus, just Go to an academic seminar related to mathematics.

"I can't remember. Is it a student I have taught?" He is not much younger than Man Guojun, but his voice is deep and gentle, probably because of work, and he pays great attention to maintaining his voice. "I have been teaching for decades, teaching There are too many students who have passed by, I really can't remember clearly. You found me today because of this Man... Man Xiaocheng?"

Hua Chong was ready to fight a tough battle, and placed several photos of Man Xiaocheng on the table, and tapped his index finger on the first one on the left, "Do you remember?"

Shen Nonghan lowered his eyes, leaned forward slightly, and raised his head for a moment, "It looks familiar, and I have some impressions. Why, this child..."

The photo had turned yellow, and Man Xiaocheng, who was frozen in the frame, was wearing a dark blue basketball jersey, standing under the basketball hoop, holding the basketball in one hand, and making a "V" towards the camera with the other.

"This is the basketball court of Wenming Measuring Tool Factory's children's school. He was the only student you took care of when you were the head teacher." Hua Chong clasped his hands together, "You have taught him for three years, and he is the representative of the mathematics class in your class. , the college entrance examination with the first grade in the class was admitted to the normal school, why do you only have a "some impression" of him? As far as I know, the school for the children of Wenming Measuring Tool Factory is poor in all aspects. There are not many students, as the head teacher, shouldn't you be impressed by students like Man Xiaocheng?"

Shen Nonghan smiled, "It's been more than ten years since I taught in Wenming Town. After I came to Los Angeles, I almost never went back to Wenming Town. The mental stress of leading students in Los Angeles No. [-] Middle School is relatively high. Big, plus I am getting old, things and people in the past have gradually faded away. Mr. Police, you haven’t answered yet, you are looking for me because of this kid named Man Xiaocheng? Has something happened to him?”

Hua Chong nodded, "Something happened to him, but not now. Five years ago, he died in a falling object incident."

Hearing this, Shan Nonghan slightly raised his chin, and frowned in confusion, "He's already dead? An object falling from a height?"

"Hmm." Hua Chong stared at Shen Nonghan's pupils, the dark color barely changed.

"That's really unfortunate, young. But..." Shan Nonghan changed his tone, "What does this have to do with me?"

Hua Chong has been trying to find some panic in Shen Nonghan's eyes, but there is no, no panic, no surprise, not the slightest bit.

But it was this extraordinary composure that made Shan Nonghan look even more suspicious.

Shan Nonghan is a high school mathematics teacher and a famous teacher in key middle schools.People who are proficient in mathematics have no difference in logical reasoning.Before committing the crime, he must have deduced countless possibilities and thought about countermeasures for possible situations.

Lies are filtered in the brain, and when they are spoken, they are clothed in the cloak of truth.

But no matter how real it looks, it can't change the essence of its lies.

"Tell me about the reason why you took the initiative to apply to be the head teacher." Hua Chong said.

"I didn't take the initiative, but the school has asked me to be the class teacher many times." Shen Nonghan said, "Before each semester starts, the school leaders will talk to me, hoping that I can also serve as the class teacher. I have repeatedly evaded, and I have no reason to continue to refuse. Think Then try to take it for a semester to see if you can adapt. If you can, continue to take it.”

"Man Xiaocheng's class, you should be quite used to it from the first year of high school to the third year of high school?"

"Fortunately."

"After Man Xiaocheng graduated, you immediately left Wenming Measuring Tool Factory's children's school and went to Los Angeles No. [-] Middle School to work."

Shen Nonghan raised his hand, "Water flows to low places and people go to high places. Los Angeles No. [-] Middle School can provide me with better treatment. In Los Angeles No. [-] Middle School, I can also display my ambitions better. Why should I Do you still want to stay in Wenming Measuring Tool Factory’s children’s school, which is not well-equipped in all aspects?”

"Before this, Los Angeles No. [-] High School has looked for you many times."

"But as a teacher, I have a teacher's code of ethics to abide by. It is immoral to change jobs before sending away a class of students."

"What a 'lost morality'." Hua Chong sneered, "As a teacher, you have not lost your morals, but what about you as a human being?"

Shen Nonghan finally showed a hint of displeasure, "Mr. Police, what do you mean by that?"

Hua Chong put Man Xiaocheng's photo aside, and took out a group photo of Man Guojun and Xiang Yunfang, "Do you know the two of them?"

This time, Shan Nonghan didn't think for a long time like when he saw Man Xiaocheng's photo, and he simply said: "This lady is an employee of the measuring tool factory, and the one next to her is her husband."

"Have you seen them?"

"Of course. The measuring tool factory's subordinate area is like a small closed society, with kindergartens, primary and secondary schools, hospitals, and vegetable markets. As long as you work in the measuring tool factory, you have more or less met each other."

"The relationship between you and them is as simple as 'meeting each other'?" Hua Chong said.

Shen Nonghan frowned, but in Hua Chong's eyes, Yun Nuo seemed to be putting on airs.

He's not really angry, he seems to have trouble being angry.

At present, the serious crime team has not obtained key evidence, and the murder weapon has not been found. Footprint identification and DNA testing will take time.Hua Chong and Shen Nonghan "wrapped a big circle", on the one hand, to disturb each other's thinking, and on the other hand, to buy time.

"You still haven't told me why you called me here today." Shan Nonghan spread his hands, "You are a policeman, I am a teacher, and we are all part of this society. I understand You may have important cases to solve, and you are ready to fully cooperate with you. But since you ask me for cooperation, you should respect me, right?"

Hua Chong crossed one leg, squinted his eyes, and deliberately put on a foolish posture, "Five years ago, Man Xiaocheng died in an accident, and all responsible parties have paid the price for his death. But some 'indirect' pushed him away. Those who are facing death live peacefully and happily.”

"I don't understand what 'indirect' means?" Shan Nonghan said: "I don't know much about the accident you mentioned. I will check it online later. In addition, I don't know much about civil disputes, but since the responsibility The party has already paid the price, which means that the follow-up compensation work is going well, what do you mean by 'indirect'?"

Hua Chong saw a calm lake in Shen Nonghan's eyes, and said straightly that this person "has profound knowledge", "Man Xiaocheng is a taxi driver, and he works the night shift for another driver. When the accident happened, he was delivering a girl." When the passenger went home, he was stopped by the guard for ten minutes on the grounds that he did not have an access control card when he passed the gate of the community. Then he was hit by the glass in the community. Some people think that this incident is closely related, and they killed Man Xiaocheng. "

"Absurd, nonsense." Shen Nonghan shook his head and pointed to his temple, "If someone thinks that way, it means that he is both legally illiterate and logically confused."

"Oh? Really?" Hua Chong said, "What about you?"

"I?"

"Are you a logical mess?"

Shen Nonghan didn't answer immediately, but frowned and looked at Hua Chong.

After a moment of silence, Hua Chong said: "This 'logically confused' person has already killed three people he thought should be dead."

Shen Nonghan raised his eyelids upwards, his eyes froze for a moment, "This... This is simply..."

"Too unbelievable? Too cruel? Or..." Hua Chong paused, "It's so satisfying?"

The line of Shen Nonghan's neck twitched, and he seemed to finally understand, and said angrily, "You think I'm this person?"

Hua Chong asked back, "Are you?"

Shan Nonghan also asked, "Do you have evidence?"

Hua Chong deliberately remained silent.

"No, right?" Shen Nonghan glanced aside, took Man Xiaocheng's photos, stacked them together, and flipped through them one by one, with a gentle and helpless tone, "Because I am Man Xiaocheng's Mathematics teacher, head teacher, and he is the best student in my class, you all think that I will avenge him? Your thinking... how to put it, is too jumpy."

Shen Nonghan laughed twice, he couldn't hear the sarcasm or blame, but he had the tolerance of an older person, "It turns out that the murder case that has been well-known in the city has this kind of relationship with me, and I don't even know it." clear."

"Of course you and Man Xiaocheng have more than a teacher-student relationship. But the teacher-student relationship is a good clue." Hua Chong said, "Why don't you think about it again, what is the relationship with Man Xiaocheng? What does mother Xiang Yunfang have to do with it?"

Shen Nonghan sighed, "I don't know what you're talking about."

"Man Xiaocheng is an outstanding young man. He used to be a math teacher just like you."

"Among my students, there are many who eventually became teachers, and more than one math teacher. Why do you think I have something to do with the case?"

Hua Chong paused for a while, "Mr. Shen, this police room is called an inquiry room, not an interrogation room. Not everyone can go to the interrogation room, but as for the interrogation room, as long as it may have a little relationship with the case, everyone is welcome." Maybe sitting where you are now. Most of them are extremely unstable, either sad, angry, nervous, or fearful. But you, calm..."

"You said 'the vast majority', so there are also a very small number of people who are not sad, angry, nervous, or afraid." Shen Nonghan said.

"That's right." Hua Chong's neck tilted slightly, and he nodded a little more angry, "But a very small number of people ended up transferring from here—the interrogation room to the interrogation room opposite."

Shannon Han's eyes darkened, but the instinctive reaction at this moment quickly returned to normal.

Hua Chong didn't miss it, "Also, Mr. Shen, you might have misunderstood me just now. Do you think I want to say that you are as calm as if you have nothing to do with the case?"

Shan Nonghan's eyebrows tightened.

"I want to say." Hua Chong said slowly: "You are so calm, as if you have practiced it countless times, as if you are pretending."

"I have met a lot of police officers, and they are very easy-going." Shen Nonghan said: "This is the first time I have encountered a criminal police officer from the Municipal Bureau today. Is this how you usually handle cases? Just find someone and ask around. Some irrelevant things. When the person being asked is nervous, he has a ghost in his heart, and if he can't get nervous like me, he just pretends?"

"It seems that you are quite familiar with the interrogation by the criminal police." Hua Chong said with a smile: "Then let me tell you one more thing. The murderer is very smart and has made a lot of preparations. The first two cases can be said to be pretty good. He is of a good standard, but in the third case, he showed his feet."

Shan Nonghan didn't say a word, but his eyes sank bit by bit.

"Is it surprising?" Hua Chong asked.

Shannon Han looked away for the first time, it was like a subconscious movement, perhaps he didn't even notice it.

He said: "If you do too many crimes, there will always be a day when you show your feet. It's no surprise."

"Yes, there is no surprise. The murderer dares to kill, and if he kills, there will be three people. Maybe he is already mentally prepared to be caught." Hua Chong said in a low and attractive voice, "Really?"

Shan Nonghan didn't immediately fall into his tricks, "You want me to say 'yes'? But Mr. Police, all this really has nothing to do with me. I feel sad for the young man Man Xiaocheng and the three dead .”

Hua Chong stood up, let out a deep breath, and looked down into Shen Nonghan's eyes, "Do you want to know what traces he left at the scene?"

The end of Shen Nonghan's eyes trembled invisibly, he didn't deliberately avoid Hua Chong's gaze, but there was a faint dodge in the bottom of his eyes.

Others can't see it, but Hua Chong can.

"It's a set of footprints." Hua Chong said softly, "A set of footprints that are clear enough to analyze his height, weight, walking style, and even his age."

The trembling at the end of Shannon Han's eyes gradually spread, rippling along the wrinkles like water waves.

"I didn't expect that, did you?" Hua Chong propped his hands on the table, "There are so many onlookers in the old community, the victim died in the garbage dump, everyone has to go to the garbage can to throw garbage, footprints overlap footprints, the police rushed When we arrive, where can we still extract the murderer's footprints?"

Shan Nonghan swallowed a mouthful of saliva with a very small movement.

"The murderer's personal quality is commendable. At least he never throws garbage like shooting a basketball from a distance of a few meters. Because he doesn't, he won't think that the people in the whole old community are all in the same way. Throwing rubbish in a way without public morals." Hua Chong smiled and said: "Mr. Shen, this kind of behavior without quality makes you feel uncomfortable and angry?"

Shan Nonghan was silent for about ten seconds, then stood up slowly, with a much more solemn and serious expression than before, "I am willing to come to the police station for the purpose of cooperating with your police investigation. But now, I have become a suspect I'm sorry, you don't have clear evidence, just relying on some messy assumptions, you want to convict me, please forgive me. "

After speaking, he walked towards the door.

"Stop." Hua Chong put his hands in his trouser pockets, straightened his back, and turned half sideways, "Did I let you go?"

Shen Nonghan said, "What? The city bureau is coming to detain you forcibly?"

Hua Chong sneered, pulled off the earplug on his left ear, and deliberately circled it twice, "Do you want evidence? I already have it. Just now my colleague told me that after preliminary identification, your footprints and the murderer's were left at the scene The footprints are roughly the same."

Shannon Han's forehead was sweating, and his lips trembled slightly, as if he was forcing himself to endure.

"Sit down, Teacher Shen." Hua Chong dragged the chair away firmly, with a chilly tone, "Of course, the preliminary appraisal result is not enough evidence for a conviction, but at least it is the reason for me to keep you here, isn't it? "

Shan Nonghan maintained his demeanor, but when he returned to his seat, his face was already pale.

??

"Fuck! Flower team! You are so cruel!" Zhang Mao shouted: "How can the footprint identification be out so quickly? Modeling and drawing are required, and we did not find any shoes that matched the footprints at Shen Nonghan's house. He It must have been dealt with long ago! It is the most troublesome to do footprint identification without shoes. Maybe the DNA test results come out, and the force analysis of the footprints has not yet been completed! You just arrested him, the murderer is really him It’s okay to say, if it’s not…”

"There is no chance." Hua Chong stood by the drinking fountain and drank two glasses of cold water one after another, "The murderer can only be him."

Zhang Mao shrugged his shoulders and whispered, "Are you so confident?"

"In almost all premeditated murders, the killer will dispose of the clothing they were wearing when they committed the crime, and the shoes are the key point. They will do this even if they know that there are no traces left at the scene, or that the traces are covered. Some of these murderers, Especially for murderers with good interpersonal relationships, they will even prepare two sets of identical clothes, dispose of the one they wore when committing the crime, and keep the clean one." Hua Chong put down his water glass and continued, "I have long thought of Shan Nonghan's clothes. The shoes will be disposed of, and the trace inspection department can only rely on walking habits, wear habits, mechanics, etc. to do footprint identification. This really takes a lot of time."

"Then you detained Shan Nonghan? Team Flower, this is an illegal operation."

"This risk is worth taking." Hua Chong said, "But what I'm most worried about now is the chain of evidence."

Zhang Trade thought for a while, "You mean, the chain of evidence we have now is not complete enough?"

"En." Hua Chong walked to his seat, grabbed a large cushion on it and hugged it in his arms.

In the past, there was only a small thin cushion provided with the chair on the armchair, which was narrow and hard.Some police officers bought their own soft cushions. Hua Chong was both lazy and busy, and spent very little time in the office chair, so there was only that small thin cushion on the armchair for a long time.

However, some time ago, the small thin cushion disappeared and was replaced by a large smoke gray pillow.

The pillow feels very good, is very large, and fits the waistline very well.

No need to deliberately ask, everyone knows that Liu Zhiqin bought it.

But Hua Chong doesn't like to lean on, and when he sits on the seat, he likes to hug the cushion.

Liu Zhiqin once said: "This cushion is used to support the waist, why are you always holding it?"

"My waist is good, so I don't need a cushion." Hua Chong said as he patted the pillow, "It's so big, can you sit down without hugging me?"

Liu Zhiqin's eyes were narrowed into a line, and the end of his eyes was pulled out in a slender width, "No matter how good your waist is, you have to take care of it."

It was only then that Hua Chong realized that there seemed to be other interpretations for his "waist is good" just now.

But after thinking about it, "good waist" is such an aboveboard word, why do you have to interpret it in other ways?

Isn't this going around on purpose?

"Direct evidence is a problem!" Zhang Mao's exclamation was like a hook, Hua Chong was hooked, and quickly recovered.

"Footprints are not the same as fingerprints." Hua Chong hugged the mat and said, "Fingerprints are the direct evidence to convict the murderer, but footprints, although they are also key evidence, are not as good as fingerprints, especially when we can't find the murderer to commit the crime. shoes."

Zhang Mao worried: "The footprints are the only evidence we have, in case this can't convict the murderer..."

"Then look for other evidence." Hua Chong was much more calm, "Shen Nonghan's confession is also very important."

"But he is very tight-lipped. I watched the surveillance just now, and you kept going around him so much, and he kept calm."

"That's because I haven't been exposed to things that make him unable to calm down." Hua Chong said: "Shen Nonghan is more rational than I imagined, but you can't tell from the surveillance, he has actually started to feel uneasy. The emotion he showed was the basis for my identification of him as the murderer."

Zhang Trade was a little excited, "What makes him unable to calm down? What is it?"

"I don't know yet, but there must be." Hua Chong said as he put down the mat and stood up.

"Flower team, where are you going?" Zhang Mao shouted.

"Continue to investigate the case." Hua Chong walked towards the door of the office, "I'll come back to drink some water, do you think I'll take a nap when I come back?"

??

The results of the DNA identification were released earlier than the results of the footprint identification. The facts are consistent with the speculation. Shan Nonghan is indeed Man Xiaocheng's biological father.

Facing the testimonial, Shan Nonghan, who had been transferred to the interrogation room, looked dull, his eyes were motionless, but his eyelids were trembling faster and faster.Then, his lips parted, his brows began to draw together, his facial lines trembled, and his hands seemed to convulse.

"This..." He seemed unable to speak anymore, tears suddenly appeared in his eyes, his voice was no longer as warm as before, and he seemed to lose his composure suddenly.

"Why, how is it possible?" He took a big breath, as if the oxygen around him was no longer enough to support his emotional load at this moment, "I must have made a mistake, I, I have no children! How could Man Xiaocheng be my child? "

Across a not wide interrogation table, Hua Chong looked at Shen Nonghan.

This "performance" is really wonderful.Numbness, shock, disbelief, and fear, Shan Nonghan, a famous mathematics teacher, gradually threw out the emotions he should present bit by bit.

Impeccably perfect.

Hua Chong didn't say a word, "appreciating" his series of analysis of emotions.

The longer the analysis, the easier it is to reveal flaws.

Shen Nonghan may have thought of a very bad possibility - the police found out his relationship with Man Xiaocheng.

To this end, he prepared a "show".

After all, even if the police are sure that he is Man Xiaocheng's biological father, they cannot conclude that he is the murderer.

The police were not even sure that he knew Man Xiaocheng was his son.

Because there is no evidence.

He had to put on a good show to prove that he knew nothing about Man Xiaocheng's life experience.

But since it is a "performance", it will naturally take a long time.How long is he going to act? 10 minutes?A quarter of an hour?Or half an hour?

A similar emotional outburst will not exceed an hour at most.

So it's over?What happens when all the emotions you're ready to explode are gone?

Hua Chong shook his toes and let Shen Nonghan play.

For a long time, Shen Nonghan covered his eyes with his right hand, his shoulders trembled violently, wondering if he had finished speaking the rehearsed words, and kept repeating: "You must have made a mistake."

"Wrong? You are a math teacher, don't you believe in science?" Hua Chong cleared his throat, and finally said, "Tell me, why did you have a relationship with Xiang Yunfang in the first place?"
