Everyone's eyes were on Jiayi. When that young face spoke seriously, her serious and determined eyes revealed a strong persuasive power.

Fang Zhenyue nodded in agreement, and everyone sat back on the tables and chairs, all looking at Jiayi's face, waiting for her to speak.

Yi Jiayi took a deep breath, walked to the whiteboard, and looked at Fang Zhenyue.

The other nodded encouragingly, and Jiayi smiled back.

Fang Zhenyue also walked to the table and chairs, found a table to sit at.

Jiayi scanned everyone's eyes, and seeing that everyone was paying attention to her, she finally cleared her throat and began her prepared speech.

She reached into her trouser pocket, took out a handful of white crystals with her left hand, and also took out a handful with her right hand, showing them to the agents, and then asked:

"Can you tell which one is sugar and which one is salt?"

"Can you taste it?" Liu Jiaming answered enthusiastically.

Jiayi shook her head, of course not.

"Then I can't tell." Gary also shook his head, "We don't go to the kitchen often."

"I have been to the kitchen, but I can't tell either." Uncle Jiu also took a closer look.

"Yes, they have almost the same appearance features." Jiayi raised her right hand and said, "This is sugar."

She raised her left hand again, "This is salt."

"I see." Gary smiled and nodded, reaching out to pick up some sugar to taste.

Jiayi smiled and handed it over with her hands, letting him twist a little and put it into his mouth. The next moment, Gary pouted at the trash can and rinsed his mouth with a cup: "Eleven is a lie!"

Jiayi couldn't help laughing. After Gary rinsed his mouth and glared at her angrily, she continued:

"I am the narrator and the planner.

“I put sugar and salt in my trouser pocket, and I am the one who tells you which one is salt and which one is sugar.

"The salt and sugar in my hands represent the truth of the case.

" The narrator is the evidence, witness, corpse, or even the murderer.

"In most of the cases we handled in the past, the narrators were all evidences, the corpses and witnesses were also part of the evidence, and even the murderer was part of the evidence. These evidences ultimately point to the murderer, and we can catch him.

"In other words, the sugar and salt appeared in my trouser pockets because of some logic. For example, Brother Gary standing on my left was holding sugar in his hand, and Brother Jiaming standing on my right was holding salt, so there would be sugar in my left trouser pocket and salt in my right trouser pocket.

"According to the natural logic of things, we will move towards the right goal.

"But there is another possibility, the narrator is not evidence. "

Gary and the others watched Jiayi throw the salt and sugar into the trash can. They vaguely understood what she meant and gradually frowned.

"What if the narrator is the murderer? What if the murderer put the sugar and salt where she wanted them, and then deceived Brother Gary by saying that the right hand was sugar?"

Jiayi pointed to the trash can, "Then faced with salt and sugar that look almost exactly the same, can everyone still judge the truth?"

"Are you saying that 'Clara might be the murderer', like 'there is sugar in the right hand', is a lie told to us by the real murderer?" Sanfu frowned, "Including all the evidence at the crime scene, are they all set by the 'narrator'? "

Jiayi nodded.

"Yesterday, Brother Sanfu was doubtful whether Clara was really the suspect, and even concluded that all of Clara's reactions during the interrogation did not look like the real murderer." Jiayi stared at Sanfu, and after looking at him for a few seconds, she said firmly:

"Maybe intuition is not reliable, but if we have a strong intuition in the process of investigating a case, we should remember it and then work hard to verify it. Not ignoring your own intuition is something all detectives should remember. This is what Brother Yue taught me on my first day in the serious crime unit." Taking a

deep breath, Jiayi nodded to Brother Sanfu again and said firmly:

"I don't think Brother Sanfu's intuition is emotional because he felt pity for seeing Clara crying."

"But all the evidence points to Clara. If it's not her, who else could it be? At least we should investigate her as a suspect now. Until she is completely clear of suspicion, we can only chase her, right? "Sanfu frowned. This is how everyone has always handled cases. When they find a clue, they investigate it to determine whether it is useful or not, and then move forward or change direction.

Why does he feel that Jiayi doesn't handle cases like this?

It's as if the clues cannot guide her, but instead she has to rely on her reasoning to guide everyone to actively identify and find clues?

Pursing his lips, Sanfu thought, if Jiayi's method is proven to be reliable, maybe she can really find a style that is completely unique to her.

An agent who is more powerful in reasoning than Brother Yue.

However, this kind of reasoning based on nothing, even going against the existing solid evidence... is it really reliable?

"Originally, this was the only way to do it, to dig out clues from the only suspect, Clara. Only when this road reaches the end will we know whether it is right or wrong, whether to turn around, or to catch Clara and send her to prison or the electric chair.

"But--"

Jiayi walked to the whiteboard, stared at the words on it, took the red pen she had been using before, and skimmed over the names of people, stopping at the three words "Qin Hongliang", and then without hesitation, drew a big circle outside. The

familiar red circle identified the murderer.

Uncle Jiu took a deep breath, looking at Jiayi with a cold look, and suddenly felt a feeling of respect or fear. After exhaling this long breath, he became excited again.

Sitting up straight, Uncle Jiu, who has always been lazy as if he has no interest in the whole world, became energetic!

"What if we find a second suspect who is hiding deeper?" Jiayi stood in front of the whiteboard, snapped the cap of the red marker, and swept through everyone's eyes like a cold knife.

"Qin Hongliang? Clara's tall pole dancer roommate?" Sanfu stood up unconsciously.

"..." Liu Jiaming scratched his head, looking at Clara in confusion, then at Qin Hongliang. He began to feel that his brain was not enough. How come there was another suspect?

"Yes." Jiayi nodded, holding a red pen to draw circles, just like when she was standing in a conference room handing over a word document to Superintendent Huang and others. She gradually raised her head and immersed herself in what she was going to say. Her soft and delicate temperament was replaced by confidence and heroism, which made everyone unconsciously raise their heads and chests, look straight at her and listen to her attentively:

"First, if a person cleans the entire room thoroughly, then she would not have left so many clues.

"In the photo, the fingerprints on the crystal ball used as the murder weapon have been wiped off, so why are there bloodstains left? Does the murderer think we are stupid? How could we not understand that she was not afraid of us finding the murder weapon because she had wiped off all her fingerprints. The murderer was so conceited, and her arrogance is revealed in details like this."

Jiayi wrote the word "arrogant" on the whiteboard as the first point of the profile, and then continued:

"Everyone sees that every room of the deceased is exceptionally clean. The first thing that comes to mind is that the deceased, Zhao Meini, was a clean person. She must have wiped the floor, and she must have put away the table and the sofa herself.

"But after we went to the scene to investigate, we found that the places that were not seen, such as the deceased Zhao Meini's closet, were very messy.

"Looking at the photos of Zhao Meini taken at home, the backgrounds are also messy.

"I believe all the detectives should have had the same doubts as me: How could a person who is obviously sloppy tidy up the room before his death? The answer is of course no.

"Then the other possibility, no matter how strange it sounds, must be the truth: after killing Zhao Meini, the murderer tidied the whole house for the deceased.

"Not just the places where she left footprints and fingerprints, but the whole room. The murderer wiped the floor, wiped the table, made up the sofa, folded the quilt, and cleaned up every place she could reach. "

Jia Yi spent the whole night looking up information last night, reading a lot of key logic for solving cases, and also learned some psychology knowledge.

One of the key concepts is that when you want to convince others, use words to imply that the listeners are in the same group as you.

For example, the sentence she just used, 'I believe all the detectives have the same doubts as me', and for example, she agreed with San Fu's intuition right away.

These are all to make everyone think that they are the same as Jia Yi, so as to brainwash the audience at this moment, so that they can think completely along her way and agree with her.

Seeing that everyone did not have a big rebuttal, even if there were doubts, they were just thinking for themselves, she knew that the things she learned were useful.

Jia Yi paused at the right time when she spoke here, and Liu Jiaming also asked very appropriately:

"Why? "

Jia Yi smiled, her eyes looked even brighter under the light:

"Because the murderer is a germophobia."

Everyone frowned at this conclusion, and then followed Jia Yi's train of thought: Is there anyone with a germophobia among the people they visited in the past two days?

Or, is Qin Hongliang, the person Jia Yi circled and identified as the murderer, a germophobia?

As if she had guessed what everyone was guessing, Jia Yi nodded vigorously, wrote the second number [geramy] on the whiteboard, and then explained:

"Yes, Qin Hongliang is a germophobia.

"When Brother Jiaming and I inspected the kitchen at Clara's house, we found that it was very clean. Most people will have grease stains in their kitchen when they cook at home, and those are stubborn stains that are very difficult to wipe clean. But Clara's kitchen is very clean, almost spotless.

"When two people share a house, it is difficult to say who is responsible for the cleanliness of the public areas, but if we look at Clara's bedroom, we will know everything. Sir Fang also mentioned earlier that Clara's bedroom was very messy, and only clothes were neatly stacked. When Brother Sanfu asked Clara, her answer was that in this line of work, clothes must be neat and not wrinkled, which will affect the appearance and make guests uncomfortable. So the house can be as messy as a garbage dump, since no one will see it, but clothes need to be worn outside, so they must be neat.

"In this way, we can conclude that the reason why the public areas are so tidy is because Qin Hongliang likes to be tidy, and the house is managed by Qin Hongliang alone. Brother Sanfu can ask about this when he interrogates Clara for the second time. I believe the answer must be the same as what I guessed."

When you are confident enough, the credibility of your words will also increase.

After hearing her words, Sanfu did not question them, but nodded instinctively. Unconsciously, he seemed to have been convinced by Jiayi.

"Again, there is another very peculiar place in Clara's house. Well, or here, we should call it Qin Hongliang's house.

"The seasonings on the kitchen table are arranged in rows of 6 small bottles and jars, with a total of 3 rows. There are 6 bowls and 6 plates in the bowl rack.

"On the small wall rack in the living room, only 6 items are placed in each row.

"The simple shoe rack at the door has 6 layers.

"The moment Qin Hongliang opened the door, I saw that her room was not only clean and out of tune with the rest of the house, but there were also 6 bottles of cosmetics on the small table. "

The first thing I did when I came to work in the morning was to ask the medical examiner, Sir Xu, to check the wounds on the chest of the deceased, Zhao Meini, based on my guess, to see if it was possible that she was stabbed 6 times. "

Hearing these words, the office was so quiet that you could hear a pin drop. Even Fang Zhenyue clenched his teeth unconsciously because of nervousness.

Everyone was completely stunned by Jiayi's reasoning.

It was difficult enough to find these details, and her reasoning based on the details was so brilliant that it made the listeners numb!

Jiayi finished speaking, looked at the time, picked up the phone and dialed the forensic department.

"Yi Jiayi from the Serious Crime Unit B, please look for Sir Xu. "

Uncle Jiu swallowed his saliva and turned to look at Gary who was sitting next to him. The young man was still staring at the whiteboard and hadn't come back to his senses.

Liu Jiaming tried hard to absorb everything Jiayi said, worried that he was the only one who was slow to react. He turned his head and looked around. Seeing that Sanfu and Gary were also frowning and thinking, he finally felt relieved.

Everyone is equally shocked and needs to digest it, that's good.

After Sir Xu answered the phone, Jiayi turned the call to hands-free and asked politely: "Sir Xu, this morning I asked you to help take a look at the chest wound of the victim in the Portland Street fruit corpse case. Is it possible that the murderer stabbed 6 times. What are the results of the examination?"

"By the way, I was just about to call you, but I was busy with the case of Group C just now and was delayed. "Sir Xu took a deep breath, which could be heard on the other end of the phone:

"The reasoning is really amazing. As a forensic doctor, I believe that evidence is above all else, but when I come into contact with detectives like you, I am often amazed. Reasoning and logic can sometimes give people a magical feeling like metaphysics.

"I have carefully tested it, and through in-depth analysis from the perspectives of minute knife edge comparison, microscopic observation of the wound, and sharp wound evidence collection, I have concluded that the probability of 6 knife wounds is more than 80%." "

Thank you, Sir Xu!" Jiayi chatted with forensic doctor Xu for a few more words before hanging up the phone.

When she straightened up and turned to everyone, her expression was more confident, and the audience also showed expressions of admiration.

Of course she is confident, she saw it with her own eyes! She

didn't mention it to Sir Xu before, just because she didn't have a clear logical chain at that time, so she didn't dare to speak out casually. After sorting out all the information she observed and thought of, as well as the information sorted out by everyone last night, of course she has the confidence to say it.

Liu Jiaming clenched his hands together, wanting to applaud, but afraid of appearing too stupid, he forced himself to hold back.

Sanfu stood there with his hands on his waist, swaying from side to side, took a deep breath, picked up the water glass and took a gulp, put the glass down, and stared at Jiayi again, as if urging: Officer Yi, speed up! I have digested it all and want to hear the rest!

Gary helped everyone to say that sentence:

"And then?" "

The number 6 seems to be very crucial. It can connect the deceased Zhao Meini and Qin Hongliang, a person who is obsessed with the number 6, and a murderer who stabbed the same wound 6 times."

Jiayi pointed the red pen at Qin Hongliang's name on the whiteboard again, added a number [6] on the side, and after writing, she turned to face the crowd. She then took a deep breath and continued:

"Next, we have already met Qin Hongliang and Clara.

"Thinking back to the crime scene, the deceased was an adult woman after all. Do you think Clara has the strength to pick her up, take off her clothes, and do so much cleaning work? "

Sanfu thought about Clara's long and thin arms. He was really afraid that Clara's arms would be broken if she was asked to hug the deceased Zhao Meini.

He also had doubts about this at the time, but Clara was tall enough and could still lift Zhao Meini with difficulty. In addition, there was no more evidence to support this point, so Sanfu did not dare to deviate from the evidence and make too many subjective speculations.

"But Qin Hongliang is different. The muscles in her arms, shoulders, neck and back are very impressive, as are her legs. In this way, a person killed Zhao Meini, carried her to the bed, and then tidied the room... The physical energy consumed after all the work may not be as much as dancing pole dancing all night.

"She is fully capable of doing it."

This is a question of the ability to commit a crime. If Clara does not have this ability and does not show that she used other techniques, then her suspicion will be reduced.

Qin Hongliang is very capable of this, and her suspicion level will be greatly increased even though she was already a suspect.

Scanning everyone with her eyes, she wrote a new word on the whiteboard: [Power]

Fang Zhenyue watched Jiayi speak more and more easily and her voice became louder and louder, and he felt a sense of relief that the Fang family's daughter had grown up.

She has grown up and can start her own business and be self-reliant.

"With so many coincidences and clues, let's look back at the existing evidence and clues.

"The hair in the case, the hair in the groomed room, it's obvious that the murderer did it on purpose."

Jiayi said, crossing the word [hair].

"Photos, since they were torn into pieces, why didn't you take them away and leave them for us as evidence? It's also false evidence. "She made a second cross on the word [photo].

"The perfume was given by Clara to the deceased Zhao Meini, and the murderer deliberately threw it into the trash can in the bathroom, as if Clara was venting her emotions. If Clara was the murderer, why did she leave so many clues related to herself? Did she really care so much about that bottle of perfume and take it away?" The third cross.

"Earrings. Clara said that it was lost a long time ago, so how could it suddenly appear and fall under the sofa, as if someone kicked it in on purpose." The fourth cross.

"Clara's lip print was left on the cup on the tea table at the crime scene. Wow, I wiped the whole room. If I were the murderer, would I let go of such a big cup if it was placed there? Even if there was no electric gun that night, the table was wiped, so wouldn't the cup be wiped? There are no fingerprints, but there is lipstick? The murderer has gone too far! She is conceited and not really smart!" The fifth cross! "

Also, the alibi." Jiayi tapped Qin Hongliang's name with the tip of her pen, "She just happened to move out with a man, and Clara didn't have any witnesses, isn't it a coincidence?"

Standing in front of the whiteboard with a clenched fist, Jiayi looked directly at each teammate and spoke word by word:

"Smearing Clara's lipstick and leaving lipstick marks at the crime scene.

"Can easily get Clara's hair.

"Recognize that the photo on the mirror is a photo of the deceased and Clara.

"Can easily get one of Clara's earrings.

"Know that the bottle of perfume from the deceased was given by Clara.

"He is familiar with the home of the deceased Zhao Meini, and he was able to do the job in a dark environment.

"These are all things that Qin Hongliang, who is Clara's roommate, colleague and friend of the deceased Zhao Meini, can do easily!

"Not to mention those other clues, coincidences, etc."

Jiayi lowered her eyebrows viciously, gritted her teeth, and said fiercely:

"When Brother Sanfu interviewed her, which of the information she revealed in her words and deeds did not imply that Clara was the murderer?"

As she spoke, Jiayi took out the notes made by Brother Sanfu yesterday and slapped it twice on the whiteboard.

Thinking of the way Qin Hongliang deceived the detective yesterday, she was still angry!

Taking a deep breath, she turned around and quickly wrote down the new one, two, three on the whiteboard:

[1. Time witness]

Since Qin Hongliang said that he had a time witness, then, does that man really exist?

We have to listen to his confession to know!

[2. Motive]

If Qin Hongliang is the murderer, then her motive must be dug deeper, and we must interview Qin Hongliang's colleagues at the Daliyuan Nightclub.

[3. Eyewitnesses]

Jiayi will go to the home of the deceased Zhao Meini in a while, and visit upstairs and downstairs to find out what the low-frequency booming sound she heard in telepathic resonance is.

Continue to dig deeper to find eyewitnesses.

[4. Other evidence]

The home that Qin Hongliang shared with Clara, and Qin Hongliang's own bedroom, we must find a way to get a search warrant and take a look.

If there is no evidence left by the murderer at the crime scene, what about the murderer's home?

Is it possible that there are some things such as trophies or rubber gloves?

[5. Clara and the deceased's sister Zhao Meizhi]

Or by catching the real murderer Qin Hongliang, we can clear the suspicion of others.

Or find other clues to clear the suspicion of others.

"If Qin Hongliang is the murderer, then this is what we have to do next." After writing the five outlines, Jiayi turned around.

When she faced everyone again, she relaxed.

Finally, she finally explained everything she thought of last night in a complete and clear manner.

On the way to work this morning, I was still thinking about these things in my mind, and I was really afraid that I couldn't explain it clearly.

But seeing everyone's expressions, Jiayi knew that at least she didn't fail.

Sanfu frowned and stared at everything that Jiayi drew with a red marker on the whiteboard, which complemented the words drawn by Fang Zhenyue's black marker, gradually showing a complete and circular murder chain.

He blinked, turned his head and looked at Jiayi, then nodded.

Uncle Jiu sat on the chair with his arms folded, wanting to go pay his respects to Master Guan again, but he managed to hold back.

Liu Jiaming opened his mouth, still staring at the whiteboard, sorting out his logic, thinking about what to do next.

Gary smacked his lips, how come Jiayi has grown up to be what she is now in the blink of an eye? She has improved so fast!

He is simply unable to catch up.

The things she said, the words she used, the clear logic and... the spirit of getting to the bottom of things and being fully engaged, all moved him.

But... I don't know why my knees are weak.

Sanfu was the first to break the silence. Although he agreed, he still had to say: "... We don't have strong evidence that cannot be refuted."

"Yes, Brother Sanfu." Jiayi nodded vigorously, and then sincerely sought help from everyone:

"It is precisely because we don't have it that we need to say it. I ask everyone to pay attention to these points when collecting evidence and interviewing."

Sanfu turned his head and looked at Fang Zhenyue.

Fang Zhenyue looked back at Sanfu and smiled softly.

After standing up, he stretched his waist, then raised his eyebrows and looked directly at Jiayi, saying with undisguised admiration:

"Excellent!"

This was the most detailed case analysis he had heard in a long time.

While listening, there was a pleasure as if he was speaking freely or screaming in KTV.

From the top of the head to the toenails, everything is transparent, the hairs on the body are stretched, the Ren and Du meridians are unblocked, a hot bath is taken, a big meal is eaten... It's so refreshing.

It's so satisfying!

If it was Sanfu standing next to the whiteboard, he would have walked up and hammered the other person's back, and stretched out his arms to hug the other person to show encouragement.

Looking at Jiayi, he had to endure these rough emotional expressions.

"Today's mission is the same as usual. Gary will visit Clara, Zhao Meini and Qin Hongliang's mutual friends by himself, and Jiaming will go to Qin Hongliang's so-called boyfriend's house. Everyone remember to follow Jiayi's ideas and pay more attention to..." Fang Zhenyue looked at the five points written by Jiayi on the whiteboard, and continued with a smile:

"On these five points, okay?"

"Yes, sir!" Everyone said in unison.

Jiayi followed suit, and then asked in a low voice: "Brother Yue, can I go to the crime scene alone? I want to visit the neighbors again."

"Sure, then Uncle Jiu can go to Zhao Meini's sister Zhao Meizhi by himself, okay?" Fang Zhenyue asked.

"No problem." Uncle Jiu nodded, walked to Jiayi, and patted Jiayi's shoulder silently.

When everyone walked out, they found that Qiu Susan was standing at the door.

If you have been concentrating on Jiayi, you won't even know when Madam came.

"Madam!" Everyone greeted Qiu Susan one by one before walking out of the police station.

Looking at the backs of the five detectives, Qiu Sushan blinked her eyes, and finally her eyes stopped at Yi Jiayi's straight back, which was not very tall but could no longer be ignored. She whispered to Fang Zhenyue:

"Yi Jiayi's team awareness is getting stronger and stronger, and she is gradually developing the ability to arrange the team and plan the rhythm of solving the case. Is this what you expected?"

Fang Zhenyue looked at the back of Yi Jiayi's round head and fell into thought.

Expected?

"No, it's my surprise."

...

...

Sanfu called Clara's home and Daliyuan Nightclub, but Clara was not there.

Just when he suspected that this woman had escaped or something, and was about to go out with everyone and go directly to Clara's house to find her, he found that she not only did not run away, but also came to the door with red and swollen peach eyes to find the detectives of the Serious Case B Team in person.

Sanfu, who was standing at the door and was stopped by the operator, was confused as he looked at the tall woman standing in front of the operator's desk, but she no longer squinted her chin and looked at people sideways.

Even if the truth was as Jiayi said, Clara was not the real murderer, a prostitute suspected of murder would not want to come to a place like the police station, right? When

Clara saw Sanfu, she walked up to him in two steps as if she had seen a relative, with a lot of thoughts in her mind, hesitating and not knowing how to express her thoughts.

Fortunately, Sanfu spoke first:

"Let's go, I was looking for you."

Then, the two walked to the interrogation room one after the other.

You Zhaohua just passed by Sanfu in the corridor, and when he saw Sanfu turning back, he couldn't help but be curious:

"Aren't you going to find the suspect?"

Looking at the woman following behind Sanfu, You Zhaohua rolled his eyes and thought that this should be the female suspect, so he asked again:

"Why did you find me so soon?"

"She came to me on her own." Sanfu turned around and looked at Clara.

Clara was unhappy with You Zhaohua's words, and immediately retorted sharply:

"I came here on my own initiative. Even if you didn't find me, I would find you to help the police solve the case. I won't leave until the case is solved. I live in the police station and watch you do your work, sir!"

What suspect or not, she didn't kill anyone!

You Zhaohua raised his eyebrows and stared at Sanfu taking Clara to the interrogation room, his facial features gradually distorted:

What 's going on?
