Jiaru's favorite snack at the school gate was salt-baked quail eggs. Before Fang Zhenyue came, she had already sat in the shop, carefully peeling a small bowl of quail eggs and putting them in the incubator, waiting for Fang Zhenyue to come and eat.
Jiajun's favorite was the crispy and crunchy butterfly cakes. The small snacks were even hot when they were just out of the oven. Jiajun took the car all the way back to Yi Ji with his mouth open, and kept baking in the oven. He was afraid that they would be cold and not crispy. He was anxiously waiting at the door of Yi Ji. When Fang Zhenyue and Jiayi came in, Jiajun immediately rushed out like a bullet, grabbed Fang Zhenyue's arm and ran away.
Finally, he brought Yuege to the oven and watched him bite the crispy cakes. Only then did he smile.
"If Brother Yue could taste the freshly baked eggs at the gate of our school, they would be so delicious." Jiajun leaned against the counter with satisfaction, his face full of satisfaction.
At this moment, the little man seemed like a big head who was waiting for his child to come home for a hot meal.
After eating two butterfly cakes, Fang Zhenyue turned around and saw the expression on Jiajun's face: "..."
He felt complicated.
After Jiajun presented his treasures, it was Jiaru's turn.
Fang Zhenyue took three or four salty, fragrant and tender quail eggs into his mouth, and nodded and gave a thumbs up under Jiaru's expectant eyes, praising them "delicious, delicious". Jiaru smiled and then separated some peeled quail eggs from the small basin and handed them to Yi Jiayi and other family members.
Even Ding Baoshu, who was busy passing by, was stuffed with two white and smooth eggs by Jiaru. Unable to chew and swallow, Ding Baoshu stuffed two eggs, one in his left cheek and the other in his right cheek, savoring the taste, just like a little goldfish with puffed cheeks and gurgling bubbles.
After dinner, Fang Zhenyue said goodbye to the Yi family, but still did not go home. Instead, he went back to the B team office and sorted out the current clues of the case on the whiteboard until midnight.
When leaving the police station, he ran into Chen Guangyao from the Forensic Department at the door.
"Is there a case?" Fang Zhenyue raised his eyebrows.
"In an autopsy of a suicide case, the body was cut into pieces by a propeller. Without a detailed autopsy report, how can we explain that the body was a suicide?" Chen Guangyao shook his short hair and took a deep breath of the fresh air outside. Only then did he feel a little relieved after being in the autopsy room for a whole day.
Walking towards the garage, he also casually exchanged greetings with Fang Zhenyue: "Will the interview be held next week or next month?"
"Next month." Fang Zhenyue rubbed his nose, said goodbye to Chen Guangyao, and drove his big jeep home.
When he drove up Sze Hoon Road and headed for the top of the mountain, he deliberately slowed down, hoping to see any more suspicious people on the road, imagining that perhaps the murderer of this case was a guy who liked to hunt wealthy people on Sze Hoon Road.
But until he turned into his garage, he did not encounter a strange car. Until
he lay down on the bed after washing up, he was still wondering where the body was dumped?
Why did the murderer kill Mr. Zhao from the villa at No. 6 Sze Hoon Road?
...
...
The chaos outside the house gradually became quiet. The other members of the Yi family had already fallen asleep, and only the small study was still on.
Jiayi sat at the desk with an A4 white paper spread out in front of her. Like the whiteboard in the police station, she could write whatever she wanted, which was very helpful in relieving her thoughts.
The big table made before the move was very much to her liking. Although Jiayi thought it could be bigger, it was already very good given the size of the house.
She spread out several books on it, one on top of the other, and on each page there were some knowledge points that might be useful.
This case was different from every other case, and Jiayi cherished this learning opportunity.
Because she could not see any emotional resonance, after the panic and anxiety faded, she looked at it rationally and thought of the phrase "trouble is Bodhi". When people encounter difficulties, in order to get out of the difficulties, they will have to think deeply. This thinking process is actually a rare opportunity for growth.
Jiayi wants to seize the opportunity and also wants to experience the perspectives and thinking of ordinary detectives in the case.
So far, the police have not yet confirmed whether the victim is dead.
But the forensic officer of the Central Police Station has issued a report, inferring that the victim is dead, and the victim's wife has also filed a missing person complaint and opened a case.
A suit with a blood hole hanging on the cliff outside the big bend of Sze Hoon Road, some footprints, some bloodstains, and some fragmentary clues. The
spray-like bloodstains of the villa at No. 6 Sze Hoon Road, the broken fingerprints on the broken glass, the footprints in the courtyard, the judgment of the forensic department on the type of car driven by the perpetrator...
After recording all the known clues, Jiayi bit the tip of the pen and prepared to start diverging her imagination.
But suddenly she was a little worried, because Uncle Nine once said that it is best not to make assumptions at will in the early stage of the case. This is a taboo for detectives.
The method commonly used by criminal investigation detectives is actually induction, not deduction.
That is, to gather all the clues and summarize them with an overall perspective. Do not jump to conclusions, but openly verify all known evidence. In this process, even any imagination should be avoided.
It is feared that the detectives will be led astray by endless imagination, causing the police force to do excessive and useless work.
The opposite method of deduction is called the logical reasoning method commonly used by detectives. In fact, some professional police officers believe that it is the fantasy of novelists, and they also believe that this method of observing and assuming first, and then looking for evidence is a waste of police time.
After all, the real world is not a novel world, and the conclusions drawn from observations and assumptions may not encounter too many surprises and reversals in novels. But the real world is far more complicated than the world of fiction. The information contained in every person and every thing can be shocking. If
a person really wants to fully understand a phenomenon in the real world, the knowledge required may cover all disciplines.
In fact, there are almost no such "erudite" polymaths in the real world.
So every time the assumption is wrong, it will cause the entire team to go in the wrong direction. In a novel, it may only take up a few pages of paper and start over. But in the real world, it may cause a team of several or even dozens of people and several months of hard work to go to waste.
It is because detectives have suffered too many losses from the method of deduction that they are wary of it and believe in the inductive method, which seems stupid but is actually reliable.
For example, a detective drinks a cup of latte and needs to find out what coffee is.
If the inductive method is used, they may find 10,000 cups of coffee and study what is in them. Then they will find that there is milk and water brewed with coffee powder in latte, and water brewed with coffee powder in frappuccino, ice cream, milk and smoothie... Finally, they come to the conclusion that the common point of all coffee is water brewed with coffee powder, and they believe that this is coffee.
If you use the deductive method, after drinking the latte, you will analyze it through your taste and vision, assuming that coffee is a drink made by mixing water, milk and sugar with coffee powder. Then you start looking for evidence, and eventually you may find a situation that completely overturns the hypothesis.
But after these days of experience accumulation and reading and learning, Jiayi found that in fact all human thinking is inseparable from induction and deduction.
Even in the inductive method of solving cases, there are elements of deduction.
For example, the detective found that people living on the Chinese mainland, Zhang San has yellow skin, Li Si has yellow skin... Wang Yi Mazi also has yellow skin.
Through the observation and induction of one hundred people, we can deduce a conclusion: all the people living on the Chinese mainland have yellow skin.
It can be seen that the inductive method is just to collect clues first, that is, to induct. Then conduct a comparative deduction.
The deduction method is probably that the detective sees a yellow-skinned person living on Chinese soil, and then infers that all people on this land have yellow skin, and then looks for Zhang San, Li Si, Wang Yimazi with yellow skin as evidence.
It can be seen that the so-called deduction method is just deduction first and then induction.
Of course, both methods may be reversed, such as white-skinned people may also appear on Chinese soil, Tom was playing parachuting and was blown to the Stanley Peninsula by the Pacific wind, etc.
After thinking about these, Jiayi relaxed again and stopped suppressing her imagination.
Mrs. Zhao said that Mr. Zhao often did not come home, so there are two most likely inferences: 1. He had an affair, so there is a certain probability that he died of murder; 2. He was really a workaholic and died of conflicts of interest.
Because the current clues have not pointed to other possibilities, no divergent assumptions will be made for the time being.
Then when everyone has a meeting tomorrow, if there are no other special clues when everyone is collecting information, these two possibilities can still be used as a reference.
If it is Brother Yue, how will he arrange the team members' next tasks?
Jiayi flipped through her notes and checked her records of Brother Yue's previous work. Then he pressed the notebook with his hand and made a simple record on the spread A4 paper:
[1. Focus on thoroughly investigating all of Mr. Zhao's affairs, including which women he has improper interactions with, and collect and interview all the confirmed and inconclusive close contacts. Cast a wide net and record all clues.]
Then Jiayi imagined what Fang Zhen Yue Surong looked like, stood up and pointed to the small bookshelf behind her, and whispered: "Sanfu, take Jiaming and Gary to ask Mr. Zhao's driver, secretary, assistant, subordinates with whom he has a good relationship, and friends, to see which women... and men he has improper relationships with."
At this time, Sanfu, Jiaming and Gary should immediately stand up, stand upright in front of Brother Yue, salute and say loudly "yes, sir." Then turn around and go out to visit.
After Sanfu and his team get the list of people Mr. Zhao has extramarital affairs with and has had close relationships with, they will be sent to call these people and ask them to come to the police station interrogation room to take statements.
Of course, the interrogation method of asking the other party to come to the police station by phone may make the interrogator think about how to deal with it in advance, increasing the difficulty of the interrogation.
If you are worried about this situation, you can also directly ask for the address of these people, and Sanfu and his team will go to their homes to interrogate and take statements.
Jiayi thought all this over, pursed her lips and smiled at the small bookshelf for a while, patted the bookshelf, said "good boy" with satisfaction, then sat back at the desk and lowered her head to write down the first point:
[2. Go to Mr. Zhao's company, interview Mr. Zhao's subordinates, partners, assistants, etc. to see if there are any competing companies, competing projects, competing personnel, etc., and then make a record of the investigation based on the list obtained. 】
After putting down the pen, Jiayi stood up again, facing the wall on the other side, and imitated Brother Yue, and whispered majestically:
"Uncle Jiu, Jiayi, and the new Xu Shaowei, the three of you go to Mr. Zhao's company and look for people who are in competition with Mr. Zhao. By the way, check Mr. Zhao's financial situation to see if he has borrowed money from outside, or if the company has cash flow problems and has borrowed from banks or loan sharks."
After imitating Brother Yue, Jiayi took another step to the root of the wall, turned around and saluted to the place where she had just stood when imitating Brother Yue, and said respectfully and politely:
"Yes, sir."
Then she picked up a pen from the table and clamped it on her ear, pretending that the pen was a cigarette. Then he imitated Uncle Jiu's lazy look and leaned to one side, nodded and said, "No problem, Brother Yue."
After that, he took the pen from his ear and held it in his mouth without lighting it. This is because Uncle Jiu has been quitting smoking recently. Even if there is a cigarette stuck in his ear, he can only hold it to satisfy his craving and cannot smoke it.
After a few seconds, Jiayi threw the pen back on the table and thought of Xu Shaowei, the new partner.
He is of medium to tall build, and he stands straight with his feet slightly turned outward, with his big feet standing on the ground very steadily. Then his hands often habitually press on his waist, pressing his pistol through his clothes. His
round eyes are wide open, and he looks energetic. He will smile instinctively after looking at people, as if he wants to leave a friendly impression on others.
When he bends his eyes, several smile lines will appear at the corners of his eyes.
In fact, even if he tries to reduce his aggression, Jiayi doesn't think he is a good-tempered person, whether it's because of his sharp eyes or something else. Even if
a smile can deceive people, eyes can't.
Jiayi stood up straight, pressed her hands on her waist, straightened her back and slightly raised her chin, smiled, and kept her eyes wide when she bends her eyes, facing forward like a fake-smiling boy, pretending to be Xu Shaowei, and said, "Yes, sir!"
Feeling that she has learned it very well, Jiayi smiled to herself and felt very satisfied.
She is quite good at observing others, and she is really a good detective seedling.
Just when she was feeling proud and got up to go to the toilet, Jiaru suddenly stared with her eyes wide open and looked around the study room with a terrified look. She asked in a trembling voice:
"Big sister, who are you talking to?"
Jiayi was not prepared to be caught in the study room directing and acting by herself, and she was also shocked.
She covered her chest and looked at Jiaru for a while. Jiaru suddenly realized and lowered her eyebrows. She walked over and hugged Jiayi with a distressed look:
"Big sister, being an agent must be very stressful, right? Let's go to bed and don't think about it. Sleep, oh? Wake up, and it will be fine tomorrow, okay?"
Jiayi was hugged by her sister, and then she thought of explaining that she was imitating the members of Group B. She also wanted to perform for her sister, so that her sister could comment on her imitation based on observation and whether it was similar.
But just as she opened her mouth, her sister's words went through her mind, and she suddenly realized -
Ah, Jiaru doesn't think that I have lost my mind because of work, right?
