Hearing Jiayi's question, Tannen smiled in an unfathomable way, as if he had been waiting for such a question. His chin lifted slightly unconsciously.

He walked from the right side of the whiteboard to the left side of the whiteboard in a self-confident and cool manner, then turned around handsomely, and like every big shot in the United States giving a presidential campaign speech, he stood out and spoke:

"First of all, the murderer was so obsessed with Gu Xiaolan that he had been obsessed with her for two years. Not only did he fantasize about being her boyfriend, but he even went so far as to kill for her. Therefore, the murderer may have suffered from extreme inferiority complex due to his physical defects, thus developing psychological and mental disorders. This defect must have affected his choice of mate in the social environment. From the conclusion drawn from the large proportion of women's experience in choosing men, we can guess that the murderer has facial defects, limb defects or height defects. He should be able to be distinguished from others by defects such as bucktoothed eyes, young baldness, extremely short stature, obesity, etc."

He finished speaking and tapped the first point on the whiteboard with the back of a marker, indicating that what he just said was the theoretical basis for this conclusion.

Giving everyone a moment to ponder, he paused until Jiayi wrote down a few words in the notebook, raised her head and looked back at him.

After nodding to Jiayi, he continued:

"Such a person must be someone with extremely unsatisfied sexual desire. What kind of person would have such characteristics? He must be unmarried and have no girlfriend."

Tannen nodded to the second point, and continued:

"A person with such a strong sexual desire must be a male between the ages of 20 and 35 who has the ability to survive independently."

He nodded to the third point.

Liu Jiaming blinked, and it sounded easy. It felt like Eleven could easily come to such a conclusion.

Turning his head to look at Jiayi, he saw that the policewoman had a calm expression, neither agreeing nor disagreeing, so he also raised his head and continued to listen to Tannen's words.

"Then, he followed Gu Xiaolan for 2 years. During this period, Gu Xiaolan also had some ambiguous news, but at that time Gu Xiaolan was not as popular as she is now, and there were not as many reports as now.

"Why didn't the murderer kill other people in the past 2 years, but killed Zhao Dongsheng at this time?"

After asking such a question, Tannen also stretched out his right index finger and pointed at everyone in the office.

No one answered, which made him feel happy that everyone else was drunk and he was the only one sober. Then he smiled and explained:

"Based on scientific profiling, it can be reasonably analyzed and concluded that the murderer has been dispelling his jealousy in other ways in the past two years, such as killing kittens and puppies.

"During this process, his desire for violence grew, his need for control expanded, his empathy and self-blame became numb, and killing cats and dogs also gave him a lot of experience in killing people.

" So we can deduce the fourth characteristic of this person, which is to look for suspects who have committed other aggressive and violent acts and focus on them. "

Sanfu frowned slightly and turned to look at Yi Jiayi. Why did he feel that... what Tannen, an expert who has studied abroad for many years, said, seemed to have been said by Eleven before?

It shouldn't be an illusion, right?

Eleven did say it before, right?

Sanfu turned around with this doubt and met Gary's expression. Sure enough, he saw that his brother was also confused. The two exchanged glances before looking up at Tannen again.

"Finally, we can see from the love letters published in the gossip magazines that the murderer's handwriting is clear. It can't be called beautiful, but at least it has a shape, and the words and sentences are fluent. So the fifth characteristic is that his cultural level is not low. It is very likely that he graduated from high school, or even more.

"Regarding his occupation, the detectives initially considered it to be a taxi driver, cleaner, etc.

"But judging from his education, his job is likely to be more than that. And after the body was found, most occupations such as cleaners who do not have private cars can be basically ruled out. So now the focus is on taxi drivers and other occupations that can afford private cars.

"We should not only check all the taxi drivers who appeared next to Gu Xiaolan, but also all other suspicious private cars. If this person appears next to Gu Xiaolan at an inappropriate time and meets my previous profiles, then he should be brought back immediately for intensive interrogation.

"Finally, we can find that based on the profile of the murderer I made, the scope previously drawn up by the detectives of Team B has been reduced in part and expanded in another part."

Tannen finished speaking, took a deep breath, turned around and asked Qiu Susan in a low and embarrassed voice:

"Is there any water to drink? "

Fang Zhenyue happened to be sitting at the desk, and he reached out to grab a cup of milk tea and handed it to Tannen.

The milk tea was actually already warm, and it was not as delicious as blowing it when it was hot and sweet, but after taking a sip, Tannen couldn't help but raise his thumb and exclaimed:

"Delicious!"

"It's our memorable milk tea from Eleven, of course it tastes good." Liu Jiaming stood up without knowing when, and it was obvious that Tannen's words still aroused the interest of some detectives.

"Fang Shazhan, based on my portrait, I think three taxi drivers among the people we checked before can be checked again. All other clues must also be re-screened and analyzed, what do you think? "Tannen looked at Fang Zhenyue tentatively.

After a series of presentations, it was finally time to get involved in Team B's investigative work.

"Which three are you talking about?" Fang Zhenyue did not answer immediately, but asked for details.

"A. Master Wang Jinlong, who is obese and has a bad temper. According to his neighbors, he is likely to be the murderer of a pet dog poisoning incident in the community. When we were squatting on Gu Xiaolan, we found him wandering around Gu Xiaolan's friend's house more than once. Although his footprints are inconsistent with those collected by the Forensic Department, we cannot rule out the possibility that the murderer deliberately created doubts and left footprints that did not belong to him to mislead the detectives, right? After all, such superfluous murderers often appeared in previous cases, right?

"b. Master Liang Xiaohong, with an average build, but a bald head, splayed eyebrows, triangular eyes, upturned nose, pig mouth with flared lips, and U-shaped face, is a typical ugly man. He is sensitive and irritable, and often conflicts with others because he thinks others are laughing at his appearance. He is also often reported by passengers for molesting customers.

"c. Master Wei Shilun, with a cleft lip, wears a mask all year round. He has a dull personality, but according to people who have seen him lose his temper, he is very hysterical and scary. Because his mother was unwilling to pay for his surgery, he chased his mother to the old house with a knife and chopped the door frame to pieces. He is also often reported by passengers for his unpleasant words.

"At the same time, the educational background of these three people all matches my description, and they all graduated from high school.

"So my suggestion is to detain these three people after interrogation and conduct a hawk trial."

At this point, he put down his marker and made a conclusion:

"Once the murderer does something bad, he will definitely leave clues, and they are often not far from us. When many detectives finally caught the murderer, they found that they had actually appeared in front of the detective more than once, so the murderer is very likely among these three people."

Tannen raised his eyebrows and asked Fang Zhenyue for his opinion with a smile:

"Fang Shazhan, let's go and arrest these three people now?"

Fang Zhenyue and Qiu Sushan looked at each other. Both of them are experienced detectives. In the cases they have handled in the past, they have never acted completely according to reasoning like Tannen.

Although Jiayi often had strange ideas before, they were all based on a lot of evidence and extremely smooth logical judgments.

Tannen makes judgments based entirely on the logic of criminal psychology...

"Inspector T, Hong Kong police cannot detain suspects without solid evidence.

"We can call these three people and ask them to come to the police station to cooperate in taking statements, but we have no right to detain them. After the statements are taken, the suspects can leave at any time."

Fang Zhenyue shook his head, frowned and continued:

"Moreover, although Master Wang Jinlong among these three people is a possibility as you said, the police must rely on evidence when investigating a case. Otherwise, they may be exposed by the media and criticized by public opinion without having to wait until the court date. This is very dangerous.

"Since the shoe prints, footprints, and foot shapes do not match the footprints of the murderer extracted by the Forensic Department, Wang Jinlong's suspicion has basically been completely cleared. Unless there is new and more powerful evidence, we cannot take further action against Wang Jinlong.

"Although the other two people are suspicious as you said, there are either time witnesses or no clear evidence to prove their absolute relevance to this case. Such people cannot become 'suspects'.

"Psychological profiling is not included in the list of 'concrete evidence' and cannot be used as evidence in court."

Tannen frowned, and while he was silent, Jiayi looked at the time, quietly walked behind Fang Zhenyue, and asked:

"Brother Yue, I'm going to the Central Police Station first."

She was afraid that if she made a new decision later, she would not be able to go to the Central Police Station to see the body.

Having just received a round of criminal psychology analysis from Tannen, she was eager to verify whether what he said was true or false. Perhaps all the truth would come to light after seeing the body. Whether to help Tannen or oppose him, she would have to wait until she saw the body to know.

Moreover, she had to take a bus to the Star Ferry Pier to take the ferry, and then take a bus to the Central Police Station after arriving at Xiangjiang Island. After seeing the body and communicating with the forensic officer about the latest report and clues, she would have to return in the same way. She had to find

time to have a full meal in the evening, and then rush back to stake out in Kwai Chung. Time was very tight, and she had to leave as soon as possible.

Fang Zhenyue nodded to Jiayi, and the female police officer stood up, saluted Qiu Susan and Tannen, and walked out of the office.

Tannen was stunned for a moment, took a half step forward to stop Jiayi, and then said to Fang Zhenyue:

"Sir Fang, in my opinion, this female agent is most suitable to pretend to be Gu Xiaolan's friend or assistant and protect Gu Xiaolan. There is an important task for her here, can you ask her to stay and we can discuss the follow-up strategy?"

Fang Zhenyue stood up and finally understood why Qiu Sushan looked so distressed when she came in.

Two leaders in a team are already very troublesome. Fortunately, he and Qiu Sushan have always cooperated well. Now there is an additional Tannen. Even if the other party is only temporarily in as an expert consultant, the running-in process is embarrassing enough.

He organized his words and began to explain to Tannen:

"Yi Jiayi had already been exposed in major newspapers before entering CID. In previous cases such as the Po Kam Bank robbery, she was also publicized by major newspapers after her meritorious service.

"This is a special situation in Hong Kong. The cooperation between the police force and the media is very close. For undercover missions, we have special teams to undertake this kind of work, and Yi Jiayi is not suitable. "

After saying that, he waved his hand, signaling Jiayi to leave quickly.

Tannen hesitated for a moment, and had to retract his foot.

As an outsider, he really didn't understand some of the conditions in Hong Kong. He had no place to display his strength and felt frustrated because he didn't understand the local situation, which made his face gloomy.

The high spirits and gentle smile when he first came in were slightly broken. He looked around the office, thinking that he must not give up because of such a small setback, but how to stick to his own ideas and make the agents of Group B respect his ideas and follow his arrangements?

Fang Zhenyue glanced at him, and didn't want to make things too awkward, not to mention that he still had some doubts about Tannen's words, so he opened his mouth:

"Madam and I will stay and have a meeting with you. Please ask the other detectives to continue to stake out according to the previous arrangement after their break. Let's discuss a new plan and then make revisions. How about that?"

Tannen looked at Fang Zhenyue's eyes and finally breathed a sigh of relief. Fortunately, although Madam Qiu asked him to be prepared to be stung by this group of proud and capable detectives, this Sir Fang seemed to be quite reasonable.

He was about to nod, but Yi Jiayi, who had already walked out of the door, suddenly turned around as if she thought of something, walked back to the office, stood at the door and said to Tannen:

"Inspector T, there is one point about the 6 o'clock you mentioned that I disagree with. I want to mention it to you. After I come back from the Central Police Station, I will discuss it with you in detail. Do you think it's okay?" "

Which point? "Tannen raised his eyebrows. He was very confident in his expertise. Even if others questioned him, it was at least formal. He welcomed discussions in this regard.

As long as they were not blindly rejecting new things, he thought it was ok.

"It's the fifth point. You judged that the murderer was highly educated, with a high school graduate or above.

"But I think the conclusion drawn from this point may need to consider the cultural bias at home and abroad.

"In a foreign country, if you want to write a eloquent love letter, you do need a higher level of education. That is due to the particularity of English.

"For example, some foreigners in later generations cannot read Shakespeare and other famous works, but can only understand the speeches of the US president.

"In English, you cannot vaguely see the meaning of a word from its 'form', but in Chinese, sometimes even if you have not learned the word, you can guess how to read it and what it means, because Chinese characters focus on sound, meaning and form.

"This is the difference between China and the West. In Chinese-speaking areas, as long as you graduate from elementary school, you can basically read most literary works."

Jiayi paused for a moment and wrote a few Chinese characters on the whiteboard to the right of Tannen's English writing. They were all very complicated characters that were basically not used in daily life. But after she wrote them, Liu Jiaming followed and read them out. Jiayi immediately nodded to indicate that Liu Jiaming read them all correctly.

Regarding the cultural differences between China and the West, there is a very classic example in later generations. Many foreigners don't understand why people in the simplified Chinese area can read traditional Chinese characters without a teacher, and people who graduate from elementary school can write very good novels.

After finishing writing, Jiayi did not wait for Tannen to say anything and continued:

"So in fact, in Hong Kong, even if you have just graduated from elementary school, it is not difficult to write a love letter like the one written by the stalker in the gossip magazines. My younger brother is only 12 years old, and his handwriting and writing style are better than those of the stalker.

"So, the murderer is not necessarily highly educated. "

Jia Yi even read a kind of artificiality of pretending to have good writing skills in the love letter.

Putting the marker into the groove of the whiteboard, Jia Yi smiled at Tannen, hurriedly checked the time, saluted, said goodbye, turned around and ran away.

Tannen was left standing there alone, sometimes looking at her back, sometimes looking at the Chinese characters she wrote on the whiteboard and the fifth message she listed.

Turning around and looking at Qiu Susan hesitantly, Madam smiled gently, fearing that he would lose face, she hurriedly invited him into her office and asked Fang Zhenyue to come to the seminar together.

Madam pulled Tannen out of the Group B office and soothed him:

"I just told you about Mr. Fang's bad temper, and forgot to tell you that Group B also has a special genius. She has some talent in profiling, and her intuition is OK. We have all been speechless by her, it's normal, it's just a small matter, don't take it seriously. Come on, T, let's go back to the office and discuss it, drink some black tea, and see if what Agent Yi Jiayi said is right..."

The remaining agents in the B team's office did not speak, staring at each other, then turned to look at the door, with complicated emotions looking at the two backs that flashed into Qiu Susan's office.

One was graceful and valiant, and although there was no smile, it seemed that the back seemed complacent.

The other one was wearing a neat suit, and could be said to have broad shoulders, a straight back, and long straight legs, but this back... No matter how you look at it, it seems a bit lonely and complicated...
