Scotland Yard refers to the Metropolitan Police Department in London, England, which is not much different from a regular police station. However, the British, especially London, has a very strong detective culture, so Scotland Yard has a relatively leading concept in criminal investigation, and the Scotland Yard detective is almost synonymous with detectives in the last century. But after modern technology replaced labor, Scotland Yard was nothing remarkable. But the detectives at Scotland Yard are still proud of it.

The fact is that today's criminal investigation relies more on technology than on people. A large proportion of cases are solved, and the first credit is due to surveillance. Originally experienced and well-skilled, police detectives were able to deduce the murderer's data from the distribution of bloodstains. Now scan the scene, and the computer will give the results, and it will be more accurate than a human. On the other hand, once criminals know how to use modern forensic technology to cover up their crimes, then traditional forensic technology will have room to play a role.

Technology can be cloned and mastered, and experience is difficult to replicate.

Taking Qin Lan as an example, he himself has jumped out of the realm of technology control, he can use technology or not rely on technology. He can make more precise inferences based on technology. After all, there are many things that cannot be replaced by machines. Polygraphs, such as those that have been on the market for decades, have never been able to become a polygraph tool in court.

However, it is undeniable that in recent years, especially in the past ten years, traditional criminal investigation technology has come to an end, and many excellent police detectives have changed careers to become economic police and cyber police.

Yuan forgot to ask: "Why did you destroy the note?"

Huade: "This is an assessment, and the standard of assessment is not about difficulty, but about fairness. It's not fair to you to deliberately leave a mark, although I profit from it. ”

It sounds like Ward is a bastard, and he sells well when he gets cheap. But Yuan Forget judged from the tone of this answer that Ward was a very old-fashioned and dogmatic Englishman. This type of person is usually difficult to get along with and difficult to get along with, but this type of person is usually not a bad person. They have stricter requirements for themselves.

Yuan Forget smiled: "Then you shouldn't take advantage of it." ”

Ward replied, "I hesitated, you gave me a problem. I don't want to make a profit, but I have to. ”

Yuan forgot for a while to understand what Hua De meant, he didn't want to eat the buffet by tricks, but after he already knew this trick, he couldn't refuse. Refusing to cut corners is a matter of ethics. The opportunity to solve a crime should not be lost because of personal morality and preferences.

In one kidnapping case, the kidnapper called the police to inform the police that I was a kidnapper, and as long as you called me Dad, I would tell you the whereabouts of the hostage. Detective: No, you can kill a soldier, you can't be humiliated, I can rely on my own ability to solve the case. It is estimated that the detective will have to be kicked out of the police station tomorrow.

If Qin Lan said so, Yuan forgot to believe it. Hua De said such words in this tone, which made Yuan Forget a little admired.

Walter: "You're a dark horse outside of the top five, and you have a good chance of being one of the top six. ”

Oh, and Walter turned out to be one of the top five. However, Huade has an overreputation, at this stage of the game, Yuan Wang's performance is good and bad, mainly depends on whether his brain is pumped correctly or not.

A girl under the age of thirty finally got the remote control, and she used the traditional criminal investigation thinking, when the case fell into the fog, she completely pushed down the clues and started sorting it out again. Collation result: No. 5 has nothing to do with the case, and No. 2 and No. 3 have something to do with the case. She focused on interrogating No. 2 and No. 3, and soon found something suspicious.

The girl and Ward had a routine and asked if the security guard had noticed the behavior of No. 3. After asking the right person and asking the right question, she applied for a body search and found the remote control.

Given that there are already a lot of beauties, this girl is not beautiful, and can even be said to be ugly. The three of them introduced each other at dinner, and the girl was also one of the top five, her name was Linda. The background startled Yuan Wang, Linda turned out to be the daughter of the expedition out of wedlock. She is as famous as Detective Qin Lan, and the daughter of the expedition who is now missing.

Looking closely, Linda could indeed see some outlines of the expedition. Expedition is different from Qin Lan, Expedition is a powerful acting school, and Qin Lan is a powerful idol faction. Linda's identity also surprised Walter, who became ill and began to inquire about matters and information related to the expedition. In addition to refusing to answer questions related to the privacy of her life experience, Linda readily answered Ward's other questions. Linda has answered similar questions no less than ten times. After the disappearance of the expedition, the detective alliance and the people of the police department have asked similar questions. They all think they have important clues, but they ignore them.

Qin Shu, who was sitting on a cold bench for breakfast today, and a middle-aged man, both of whom were deducted points for searching for the wrong person. Qin Shu lowered his head and drew circles with his fingers on the small short table, Qin Lan's face was ugly. His pampered beautiful daughter sits on a cold bench, and the ugly daughter who doesn't care about the expedition is eating a buffet, what kind of society is this?

Fortunately, his apprentice has added some face to himself in this question. Yuan Forget was the first person to eat at the buffet.

......

Breakfast is not given in vain, and naturally there is no free lunch, and the candidates feel that they are not here to participate in the assessment, but to compete for dinner.

At 11 p.m., all candidates gather in front of the apartment building.

Qin Lan took the megaphone as usual: "A good detective sometimes needs to think about it. Imagine yourself as a criminal, understand the criminal, and fully consider the criminal's ability and means of counter-reconnaissance. Qin Lan waved his hand.

Two security guards carried up a table with everyone's number plates.

Qin Lan said: "You are thieves now, you have ten minutes to hide your number plate, and the scope is this building." 20 security guards will spend an hour conducting a carpet search of the entire building. 3 points will be deducted if the number plate is found, and you will sit on a cold bench and watch others eat lunch. If you do not find the number plate, you will be given 3 points and you can enjoy the dishes made by the specially hired five-star chef. ”

Qin Lan said: "20 search security guards, for every number plate you find, you can get a prize of one thousand dollars." ”

"Wow. Security guards on both sides applauded.

Qin Lan: "Three rules. 1. You are not allowed to enter the room where the test taker lives, including your own room. 2. It cannot be hidden in the human body. 3. Candidates who are not found after the time is up must lead a security guard to get the numbered ticket back within 10 minutes. Now please pick up your numbered badges and enter the apartment building. ”

The candidates took turns to take their number plates and walked to the living room. The two security guards closed the door, and Qin Lan said on the loudspeaker: "The ten-minute timer starts." ”

At first, no one went upstairs, because the second to fifth floors were exactly the same structure, and there were no rooms where the candidates lived were bare, and there was nothing else except for the toilet in the first place.

Qin Lan shouted: "Remember, it's inside the building, and the window sill placed on the windowsill also belongs to the outside of the building." Don't pick words with me, what I hate the most is a lawyer. ”

Yuan Forget was the first person to go upstairs, and with his understanding of Qin Lan, it was not that simple. Besides, there are too many people on the first floor. Someone even started a fight over a good hiding place.

Looking at the second floor, going up to the third floor, and then going up to the fourth floor, Yuan Forget began to regret his choice, bare and empty, no shit. The pillars, floors, and even the stairs are all made of concrete, and there are no holes to dig out.

Door!

Yuan Forget began to check the wooden doors of each room, and the emperor lived up to his wishes, Yuan Forget found a crack in a wooden door that could be stuffed into the sign. Just about to do it, Yuan Wang's heart sighed, and he ran to room 07 on the fifth floor to take a look, and sure enough, like 407, there was also a crack in the door of room 507.

This is the trap.

Yuan Wang's wit moved, entered the bathroom of 507, and placed the number plate against the wall. If you can't see the number plate outside, you have to go into the bathroom and turn around and come out, and look down to see the number plate placed on the edge of the wall. This toilet is not big, and once you go in, you can come out with a turn.

It's not a very good hiding place, but it's already the best hiding place that Yuan Wang can find. What's more, there is only one minute left.

When he went downstairs, Yuan Forget saw Qin Shu preparing to stuff the number plate into the crack of the 407 wooden door. Yuan forgot to be opposite Qin Shu, and immediately whistled and gestured to indicate that the position was not safe.

Qin Shu pointed to his wrist, meaning that there was no time.

Yuan forgot to point to the room and entered.

Qin Shu understood that the 407 wooden door was a trap, and the security guards were likely to only inspect the wooden door. Because according to normal reasoning, if no one sees through the trap, the crack is the best hiding place. If someone sees through the trap, they will definitely stay away from room 07.

......

When the time came, 20 security guards entered the building, and all the candidates came out to wait. Qin Lan took the megaphone and shouted: "The wooden doors of rooms 207, 307, 407, and 507 all have gaps suitable for hiding number plates. ”

Ten minutes later, security guards had found eleven numbered plates. This result was worse than Qin Lan expected. Because he knows that what he finds in ten minutes can be easily found, and he may not be able to find eleven number plates after ten minutes.

Qin Lan took the megaphone: "I know that some candidates are hungry with their chests against their backs, and I see that some candidates have already guessed that they may not be able to eat lunch." It's so pathetic, therefore, I decided to give everyone a chance: the whistleblower. Any candidate who assists a security guard in finding the numbered plate within one minute will receive 200 grams of beef. You can continue to challenge, but if you fail a challenge, you will be disqualified, but there will be no penalty. ”

Qin Lan: "I believe that many people know the hiding places of other candidates, and they also know that everyone is embarrassed to betray others. So now by self-activity, there is a security guard standing at the back door, and if you are willing to challenge the whistleblower, you can talk to him. He would use the walkie-talkie to call a security guard to cooperate with the whistleblower. ”

Yuan Forget suddenly felt a sad and pleading gaze, and when he looked back, Qin Shu looked at him pitifully. Yuan was stunned: "Don't you, sell me for a meal?"

Qin Shu hugged Yuan Wang's arm with both hands and said sadly: "It's the first time I've been hungry for so long. ”

Yuan Wangdao: "Have confidence in yourself. ”

Qin Shu looked at Yuan Forget: "You won't betray me for a meal, right?"

Yuan Forget: "It seems that you are really hungry and have lost your basic judgment ability. It will depend on the situation in a moment, and if you are found, you will betray me. After saying this, Yuan Forget felt a little fake. If the Qin Shu sign in room 407 is found, the sign he hid in room 507 will not be spared.

Qin Shu: "Cut! Just kidding, I won't betray you if I starve to death." I'm just a little nervous. After Qin Lan explained the mechanism of room 07, Qin Shu was very nervous. This means that there will be security guards who will go to room 07 to check. If you don't want to pee, or go in and go around, you will not eat for more than 24 hours.

To be honest, Qin Shu is more concerned about lunch now. This was the first time Qin Shu had experienced hunger since she could remember, and the hunger of Yuan Wang's childhood made her feel deeply, and she felt that she should be glad that Yuan Wang's psychology was still healthy.

After the security guards registered the number plates they had scavenged, they stacked them in the box in front of Qin Lan, and several security guards whispered to Qin Lan. With the increasing number of number plates, there were also whistleblowers, which further led to the number plates being searched one by one.

Qin Lan took the roll call book to draw a line, and after the time was over, Qin Lan gathered everyone and looked at the roll call book for a while: "Five Xiaoqiang are five Xiaoqiang, this assessment competition is really a master, and the five Xiaoqiang are dining." Please. ”

204, 304, 404, 504 and Walter enter the living room and head to the dining room. One of the five people, in addition to Walter, was an elderly man and a woman in her sixties. One is bald in his thirties. One is Linda, the daughter of the expedition. And a very beautiful man.

Yuan Forget has always had some opinions about this man, and he can't tell whether 204 is male or female. The man wore a rugged black denim suit, but this denim suit could not hide his delicate movements and satin-like skin. The hair is short, with a men's hairstyle of four or six openings, and it is covered with gel water and moisturizer. The eyelashes are long and have a scarf.

Generally speaking, if the subject of the video on the Internet, or the woman in the online photo, wears a scarf, it is more likely that the person is a man. But men wear scarves, which makes people wonder.

The height is very average, one meter six five. If it is a male, it means that it has a little bit of pectorals, and if it is a woman, it means that it has only a little bit of pectorals. The legs are straight and long and white.

Qin Shu asked first: "Male and female?" A man is more beautiful than himself, which is unacceptable. Of course, it's not easy to accept the fact that a woman is more beautiful than herself. TMD, it's better not to have someone prettier than yourself.

Yuan forgot to see his back into the living room: "I don't understand." "Nowadays, people really have to dress up, and it is difficult to identify their gender with the naked eye.

Qin Lan took the roll call: "208, 306, 320 will go to dinner, and the others will serve on the bench." ”

"Ahh

Yuan Forget was also defeated, and after Yuan Forget and Zhao Wu mentioned this exam question, Zhao Wu felt that it was very simple, and a number plate could be perfectly hidden in ten minutes. First of all, you need props, glue and screwdriver, if you don't have rice, noodles, thick nose, mixed feces, etc., you can replace glue. Screwdrivers can be replaced with hard objects.

Step 1: Scrape the cement floor and obtain the masking powder.

Step 2: Apply the powder to one side.

Step 3: Attach the numbered bib to the wall or ceiling. If you can't find the glue, you can place the number plate on the ground and spread the masking powder. Since the masking powder is the same color as the cement of the walls, ceilings and floors, it is difficult to spot.

If you are on the ground floor, there is a large number of kitchen equipment, the living room utensils assist, and it is even simpler to hide the number plate.

Zhao Wu casually said several ways.

Zhao Wu thinks that hiding something in a building, as long as it is not stupid, how can it be found out. Not to mention the number plate, you can hide a person without dividing the body.

Yuan Forget did not comment on this.
