The two of them still walked back according to the distance they came from. First, they took a taxi to the city, and then went to the train station to get a ticket. The return car was a high-speed train.
The moving train is much cleaner than the old train. Lu Siyu looked at the noisy environment and said to Song Wen: "Let's go to the dining car. I'll treat you to something to drink. There is a table over there, where you can write. And At this point, there should be not many people there, so it is convenient to discuss the case."
Sure enough, as he said, now is not the time for meals. Compared with ordinary carriages, the dining car is much looser and quieter. Two people occupy four seats. There is a small table in front of it. Lu Siyu gave Song Wen an order. I ordered drinks, melon seeds and snacks, and drank the water in the thermos cup by myself.
Song Wen was a little sleepy at this time. In order not to let himself fall asleep, he opened the notebook and started to draw. When the train swayed, the control of the pen tip was much more difficult than usual, but it made the drawn lines a little more focused. After a while, Song Wen drew a girl's face on the paper. It was Lin Wanwan's face. It looked indifferent and pitiful, but her eyes were unfathomable.
The number of stops the train stopped at was much less than when it came. The train was moving forward, and the scenery outside the window kept changing. It gradually moved from the town to the fertile fields, and then passed a few caves. Song Wen finished painting the portrait of the figure. Looking up, Lu Siyu sat opposite him, opened the record book, and bit his nails habitually while watching.
Song Wen found that Lu Siyu had the habit of biting his fingers when he was thinking attentively. Now he bites the fingers of his left hand in his mouth, and writes and draws on the notebook with his right hand. Song Wen looks carefully, Lu Siyu's pair is clean On his slender, well-joined hands, all the nails were bitten by him to the level of the belly of his fingers. Under Song Wen's gaze, Lu Siyu put the notebook on the table and said, "I finally figured it out, poisoning. The matter still has nothing to do with Lin Wanwan."
"What?" Hearing this sentence, Song Wen became interested and leaned forward to look. In the book, Lu Siyu drew the relationships of the characters, with Lin Wanwan as the center, the dormitory on one side and the family on the other. The family made a family tree and marked everyone they knew so far.
"Class." Lu Siyu pointed to the picture on the book and came to a conclusion.
Song Wen was a little puzzled, and Lu Siyu clicked on the picture again, "The class of the dormitory, and the class of her family."
Song Wen was even more confused: "There are only a few people in total, so how did you create a class?"
"Do you remember when I mentioned the gaslight effect?" Lu Siyu asked him.
Song Wen nodded.
Lu Siyu clicked the names written on the bottom of the two sides on the picture: "If in the family, the tortured and manipulated character is the mother, in the dormitory, the tortured person may be Guo Hua."
Song Wen looked at the picture drawn by Lu Siyu. It was divided into three levels. On the family side, the first level was Lin Wanwan, the second level was younger brother, stepfather, and the third level was mother.
On the other side of the dormitory, Lin Wanwan was on the first level, Dong Fang and Ma Aijing were on the second level, and Guo Hua was on the third level.
Song Wen understood a little: "What do you mean, there are classes among these people, and Lin Wanwan is the one who controls?"
Song Wen still remembered that when everyone had a disagreement about whether Lin Wanwan was a suspect yesterday, Lu Siyu said that Lin Wanwan was a manipulative personality. He has read some psychology courses and knows more about controlling personalities than others. Many people with controlling personalities are not always strong, arrogant, impulsive, but may also be innocent, innocent, or even Humble, but their hearts are arrogant, paranoid, and even suspicious. For such people, their innocent appearance is their camouflage, and they cleverly hide their intentions under friendly friendship, like wolves in sheep's clothing in a crowd.
Lu Siyu explained: "Lin Wanwan is her mother's proudest and most trusted daughter, and she is Guo Hua's closest friend. Such a relationship allows her to grasp their weaknesses and better deceive them. Intuitively, the victim is trapped in a passive relationship.”
Even now, they can't ask Wang Wenyan any complaints about her daughter. But this daughter is undoubtedly the key figure in her status in the family. The same is true for Guo Hua. Dong Fang's clothes can't disappear out of thin air. Why did Guo Hua's untouched notebook get wet? There are some clues in these things.
Class is an inevitable product of social development, as long as there are people, there will be classes. Everyone is in a different position, differentiated into different levels, and each performs his own role.
In the dormitory and family, Lin Wanwan is a vested interest, standing at the top of the pyramid.
At home, her mother always responds to her needs and leaves her good things everywhere. Her younger brother is still very weak and her stepfather is not at home all the year round. She is the hope and pride of the family. In the dormitory, Guo Hua served her meals or picked her up in the rain. These were both good friends and her being enslaved and controlled by her. Guo Hua had the idea of moving out of the dormitory several times, but gave up the idea several times, apparently it was also related to Lin Wanwan.
Song Wen frowned: "Lin Wanwan is just a 20-year-old girl, how did this relationship come about?" Intuition told him that Lu Siyu was right, but he didn't believe that this little girl could be without Teachers are self-taught to this extent.
"The formation of each person's personality is inseparable from her growing environment and experience. The same is true for Lin Wanwan. The formation of her personality is related to her family and the things she has experienced since she was a child. We can learn from the conversation that Lin Wanwan grew up in a patriarchal grandparents’ family. The family education is very strict, the family hierarchy is strict, and each family member has their own responsibilities. I have Lin Wanwan’s body and her family. , found several more important information. The first one, the scar, the second one, the chocolate, and the third one, the doll."
Speaking, Lu Siyu drew a bracket, wrote these three key words, and then continued: "The environment she is in is harsh and depressing. Coercion and lure, both soft and hard, hitting a stick, giving a candy, Her scars are the punishment for wrongdoing, her chocolate is the reward, and she was taught in such an environment, like a slave, and naturally integrated these into her world."
"Little Lin Wanwan was like a blank piece of paper. The first thing she suffered was endless suffering, beatings and scolding from her biological father, and harsh scolding from her grandmother and grandfather, which hurt her young heart. Under such circumstances, the sudden Candy is the best consolation, she is like a hostage in Stockholm, gradually attracted by this little bit of tenderness hidden under domestic violence. While being abused, she is also learning."
Speaking of this, Lu Siyu paused slightly and looked at Song Wen: "The sugar must be delicious, and the whip must be accurate. If things go on like this, the prey will be firmly fixed by his side."
This is the most important thing Lin Wanwan has learned in that family, and it is also something that will affect her life. Next, Lu Siyu continued to draw a timeline: "After she got out of that environment, she has reached the age of ten. At this time, her mother's doting and her stepfather's indifference are replaced. Lin Wanwan is a smart girl, she Apply the methods learned in the previous family and use these instincts in her life."
Later, Lu Siyu drew a straight line between Lin Wanwan's name and Wang Wenyan: "She doesn't love her mother, and even regards her as the source of her painful childhood. In the second home, she treats herself Her mother, Wang Wenyan, was regarded as the object of enslavement. While approaching her and forming an emotional bond with her, she denied her, broke her will, and subjected the controlled person to mental torture. It will become more and more dependent, and eventually coexistence will be formed.”
"Later, when she came to school, she made Guo Wei the object of this manipulation. At school, Lin Wanwan kept instilling some concepts on Guo Wei: Although your family background is not good, your character is withdrawn and weak, but I am the only one who Hello, I am your best friend. You must not let me down, betray me. As a good friend, it is normal for you to do something for me. Only I am good to you, and your world is only me. "
These are the words that some little girls often say. Girls who have just gone to college, have left their families, and are not deeply involved in the world. They are easily confused by such friendships. But now these are analyzed by Lu Siyu, but it makes Song Wen feel cold behind his back.
Lu Siyu concluded: "This is a twisted and perverted relationship between girlfriends." He paused, "It's more like a relationship between a slave and a master."
At first, Lin Wanwan gained Guo Hua's trust, and then she kept questioning her, denying her, isolating her, making her lose herself more and more and rely more on her only friend. At that time, Guo Hua also became obedient to her. This process sounds simple, but in fact, it has undergone several months or even years, and it has been completed bit by bit.
Under such analysis, Lin Wanwan's portrait became much clearer, and the relationship between Lin Wanwan and Guo Hua became clearer. She no longer looks innocent and is closely related to this bedroom.
"What about dolls?" Song Wen noticed that Lu Siyu mentioned three things, but only two points were mentioned during the analysis.
Lu Siyu blinked and looked at him: "She has grown up and has contact with society and people, so she doesn't need those dolls."
Yes, her family are her dolls, her classmates are her dolls, her colleagues are her dolls, even the police officers who are investigating the case are no different from those dolls in her eyes. It's her way of doing things, unconsciously selecting targets in the crowd for her use. Her showing of weakness and her pitifulness are all her weapons.
From all the signs that can be seen now, Lin Wanwan doesn't care about Guo Wei very much, or in other words, she doesn't care about anyone other than herself, she keeps tying Guo Wei, making her the thread in her hand doll, and the strings are getting tighter and tighter.
She likes this kind of game between people.
Although Song Wen didn't understand the perverted heart well enough, he was a smart person after all. He quickly figured out the plot. This girl was cunning and clever. When they first met, they saw through her lies about the source of the poison, and then she changed her rhetoric. She once pretended to jump off the building in order to gain the sympathy of others. Such a girl who looks very weak is naturally in a weak position. She is even being selected among the police. For example, she involuntarily developed sympathy for her, and Lao Jia, who was seduced by her... thus affects whether they suspect her or not. human judgment.
After understanding this, Song Wen said to Lu Siyu: "I understand that she will find people who are suitable for control in the crowd, but what does this have to do with class? Or, how does class arise?"
The train came here, and suddenly a cloud passed by, and the fine sunlight was thrown through the cracks of the cloud, with a touch of gold, and it was hitting Lu Siyu's sharply articulated fingers, illuminating the slightly pale hand like a A beautiful piece of art, he clenched the pen tightly and drew several arrows on the map, "Everyone is in the game. She is building relationships to achieve the purpose of manipulating and confusing others."
After all, it is simple and easy to control a person, but it is not so easy to control a group. And the manipulation of groups should be more careful.
Lu Siyu thought for a moment, wondering how he could explain it to Song Wen: "I'll tell you a fable, have you heard of the wet monkey experiment?"
Song Wen was somewhat impressed by the word, "You're talking about that experiment, right? Put five monkeys in a cage, and put bananas on the top. As long as there are monkeys picking bananas, they will be drenched in water, so as long as there are When monkeys go to pick bananas, they will be beaten by other monkeys. Later, when new monkeys are put in, the monkeys will still do this. The scientists replaced the water gun on the top, and no monkeys dare to take bananas anymore.”
Lu Siyu turned the pen in his hand and said, "This experiment is from a business book, so there is no conclusion whether the experiment has been carried out or not. It can be regarded as a story. What I want to say is a derivative version of this story."
"It's still a cage, with four monkeys, monkey ABCD. The water pipe is relatively small, and only the monkeys who go to get the bananas will be showered. The strongest monkey among the monkeys is monkey A. He wants to eat bananas, but he doesn't want to be drenched. got wet, so he asked the weakest monkey D to get the banana. Monkey D was drenched in water, monkey A ate the banana, monkeys B and C envied monkey A for eating the banana, but they were better than the wet monkey D Much happier."
"At this time, a wonderful psychology came into being. Monkey BC faced monkey A, and they felt inferior, but when faced with monkey D, they felt superior. So, four monkeys have three classes, and the class is in monkeys. generated in the crowd.”
The situation in reality is definitely more complicated than this story, but the story is simple and easy to understand, Song Wen sorted out his thoughts, "You mean, at home, the mother is the weak monkey D, in the dormitory. , Guo Hua is the weak monkey D. And Lin Wanwan is the monkey A?"
Lu Siyu nodded: "even sometimes, that weak monkey D is a gift she gave to monkeys B and C. Others will follow the bully's behavior and start bullying them. It's like his younger brother. Will scold her mother, Dong Fang and Ma Aijing will scold Guo Hua. Lin Wanwan is constantly adjusting various relationships, intentional and unintentional. Interpersonal relationships in the dormitory itself have contradictions and weaknesses. You can make a fuss about your own contradictions.”
Speaking of which, Lu Siyu licked his lips habitually. From Song Wen's point of view, his eyelashes were clear, but his eyes were unfathomable: "Through punishment and reward, the beginning may be just a small game. , it was their maliciousness when Guo Hua was not in the dormitory, but the violence would gradually escalate. In this way, in the relationship of the dormitory, Lin Wanwan became the top of the class. In the dormitory, she spent Dong Fang's money. Qian, with the help of Ma Aijing's relationship, the paper got a high score, and Guo Hua brought her tea and water to wash her clothes. She even knew her mobile phone password, so her mobile phone was so clean, and when she dialed 120, she took it easily. I have Guo Hua's cell phone, because that cell phone is usually used by her."
Seeing that Song Wen didn't interrupt, Lu Siyu continued, his voice was low and seductive enough to deceive people: "The poison was really brought by Guo Hua, and she also bought the chocolate, which is probably what Lin Wanwan dared to do. Let's interrogate Guo Wei, either because Guo Wei was already under coercion, or she was poisoned by Lin Wanwan's encouragement, or Guo Wei couldn't believe her memory and didn't have the courage to identify her. best friend."
Lu Siyu speaks a lot today. When caught in this kind of reasoning and logic, he is like a child who has made a difficult problem and wants to share his achievements with others. This time, he is no longer hiding in the dark, but sharp-edged Be exposed. Song Wen looked at Lu Siyu in front of him. At this time, he was no longer as slow, soft and cute, and harmless to humans and animals. There was a kind of excitement on his handsome and pale face, cold and ruthless, rational and wise, and his whole person seemed dangerous and charming.
These things are abnormal, bizarre but completely reasonable. Once this logic is accepted, many things in the case can make sense. Song Wen felt that he had finally sorted out the case, as if he had removed the refracting mirrors in the kaleidoscope, so that the relationship behind him could be presented in front of him.
The truth that had been bothering him finally appeared in front of him, but Song Wen was not happy at all, he rubbed his eyebrows: "I understand your logic, but this situation is still based on assumptions. Psychological manipulation listens to It's too mysterious, we can't rely on this to persuade the judge or even Gu Ju, I guess it will be difficult to persuade Lao Jia, and some theoretical basis is still needed."
Lu Siyu said: "The core of this case is still poisoning. I am analyzing the logic behind the case and the relationship between the characters with these so-called theoretical knowledge. But this kind of manipulation is completely feasible." He thought for a while and said, "This way Cases are not common in China, but there have been a few cases in Japan. The more famous ones are the Kitakyushu prison homicide case.”
Song Wen recalled, "Is it the case in the 1990s in which a couple imprisoned and murdered seven people?" He had read some relevant materials, but it still makes his scalp tingling in retrospect.
Lu Siyu corrected: "It's not that they killed, but let the victims kill each other." Then he sat up straight, "But this case is just similar, because he used electric shocks when manipulating people. It's not purely psychological manipulation. I just use this example to illustrate that if a person is manipulated by other people, even relatives can face each other with swords."
Song Wen knew about this case in the past, but every time he heard it, he still felt incredible. The education he received since he was a child and his upbringing made him feel that such things are unbelievable, but these are real evils that exist in the world.
Lu Siyu thought for a while and added: "There are similar cases and the Hyogo serial murder case where the suspect is Kakuda Miyoko. That old lady is known as a mind killer, and she mainly uses brainwashing to manipulate and kill. She hastened the violence, The three factors of sex and psychology turned the victim's family into a gladiatorial arena. Over the years, at least seven people in Japan were killed because of her, and she was not arrested until 2012. Later, with her suicide, many Details and truth are unknown."
After talking about the two cases, Lu Siyu returned to this case: "However, these are much more serious than the cases we are facing, at least I think that Lin Wanwan has not developed to the point of completely manipulating others to kill, and therefore, in the end, Guo Hua ran out of the dormitory and called for help."
Song Wen asked, "Then what do you think Lin Wanwan's motive for killing? What was it?"
Lu Siyu stretched out two fingers, "The master wants to kill the slave for two reasons. First, he doesn't need the slave anymore, and second, the slave is out of control and wants to leave him."
Seeing that Song Wen was a little puzzled, Lu Siyu began to explain in detail: "In the previous interrogation, when I asked about Yaomao, once I replaced 'Guo Hua' with 'you', she did not refute me. , According to our investigation, Lin Wanwan is more like the master of all this. Guo Wei's purpose is to make the cat stop quarreling, and she is killing cats to satisfy her desires, and she is simulating murder. Practice. I think Lin Wanwan's nature contains a cruel side of killing. In this society, there are some people who will use killing to solve problems for reasons that are difficult for ordinary people to understand. "
Song Wen nodded when he heard this. In his work as a criminal police officer in the past few years, he encountered a lot of perverts: "I understand what you mean, most people in society are not such people, but we can't Deny the existence of this alien."
Lu Siyu lowered his head and looked at the relationship map of the characters in front of him, his fingers twitching slightly, and he said his speculation: "Lin Wanwan came to the school from home, and soon found that the dormitory was a place that fascinated her even more. The control is escalating in the dormitory, where she can live more freely than at home. At this time, she feels that she does not need her family, so she tries to kill her parents and brother, she is tired of those People, she thinks they're useless, despises them, and she wants to get rid of her family of origin."
Lu Siyu paused and continued: "As for killing the classmates in the dormitory, it was because she discovered the gap between her own family and other people's families. This is a kind of strong jealousy. If it is normal, then it is just jealousy. , because in the dorm where she built relationships, she can find balance and comfort in other areas. But once she graduates, this balance is broken. Those people are going to be free from her control, which she cannot. Tolerance." Having said that, he raised his head and asked Song Wen, "You noticed that Lin Wanwan didn't make any preparations for graduation."
Song Wen thought for a while, lowered his head and pondered: "Dong Fang's family has found a job for her. Ma Aijing is going abroad, and even Guo Hua has bought a new mobile phone and is ready to start a new life, and Lin Wanwan, in all our searches, even one I haven’t even prepared a graduation resume.” In the second semester of their senior year, all the students were eager to enter the society, but Lin Wanwan didn’t want to come out.
If Lin Wanwan is really the murderer, the initial gas incident might just be her attempt. This time, her behavior has been escalated. She is more cautious, careful, and calmer. From the planning to the final execution, there may even be a few Months, every time, their yearning for life after graduation is stimulating her.
So, she was smart and planned everything. Only people like her can survive and be cleared of suspicion. Those who are regarded as slaves by her will never escape her control and will be kept by her forever. here…
Lu Siyu nodded lightly, leaning his body on the back of the chair, he picked up his thermos cup, drank the water inside, and tried to bring himself into Lin Wanwan's mind: "Just think that these people will be separated from her. Control and she'll go crazy."
The two suddenly fell silent in unison. The two of them sat on the train facing each other. The train swayed, and the sound of friction with the rails was heard from time to time.
As a police officer, Song Wen often reflects on why he didn't see far enough to see the whole truth, but whenever they approached the detection of the case, he would have such a kind of fear from the bottom of his heart. It turns out that people's hearts can grow like this.
He looked up and saw people around him, men and women, old and young, everyone had a beating heart, a working brain, they were playing with their mobile phones, they were chatting and laughing, this was the person he couldn't see through, the most complex people.
In the end, his eyes fell on Lu Siyu, what he saw in his eyes was different from what he saw, and what he felt was also different from him. He is smart, sharp, and meticulous.
On weekdays, Lu Siyu has various disguises on his body. It seems that he is the real him now. He is sharp-edged and evil. He could feel Lu Siyu's excitement when he talked about those crimes. He remembered the theory of the criminal psychology teacher in the police academy. Only by fully understanding the criminal, having a resonance, and having the same thinking as the criminal, can he correctly analyze the criminal behavior and describe the criminal.
There was a flash of lakes and mountains outside the train window, reflecting on Lu Siyu's face. His hand holding the pen paused, and he seemed to realize that in his reasoning just now, many perspectives had not been converted. Human logical thinking and thinking methods, Speaking habits, like fingerprints, have their own unique ways, and no matter how well camouflaged they are, these ways will still reveal themselves unconsciously.
Song Wen didn't pursue it too much, and instead asked him: "The truth is that there is nothing wrong with this, but the current case has no witnesses, so the evidence chain needs to be complete... We also need some direct evidence."
Lu Siyu thought for a moment, picked up the book, and wrote the word "chocolate" on it.
Delicious candy becomes a deadly poison, and it all starts and ends here.
Lu Siyu raised his head and looked at Song Wen: "I have a bold idea. If my reasoning is correct, I think there may be evidence to prove it is her." Then he paused and said, "But Team Song, I hope you can promise me one thing first."
Song Wen raised his eyebrows: "What's the matter?"
