Provincial Public Security Department.

After the Ministry of Public Security issued a document confirming that Shao Shilin would lead the formation of a task force, the files that were sent to Minister Li's desk were never broken. These are the lists of candidates recommended by various places. A week ago, Mr. Li sent out a written test question. In the returned test papers, Mr. Li selected the top 100 people with the best scores.

Today, these 100 people finally came to the Provincial Public Security Department to prepare for interviews. Among these hundred people, Jiang He accounted for one.

On a rainy day, the road was slippery, and Wang Chao was still driving Jiang He on the road.

The detectives who passed the written test were already sitting in a large conference room at this moment.

According to the notice, the interview should have been going on for half an hour, but at this moment, not only did not see Mr. Shao, but even the staff of a provincial department did not see it. The criminal policemen sitting in the conference room for the interview looked at each other, and they didn't understand what happened and why the exam was delayed.

"Teacher." Director Wen looked at Mr. Shao, who was sitting on the side and drinking three cups of tea, and couldn't help asking: "Isn't it a member of the selection task force today? The people sitting in the conference room are among the best in the country. Detective. When are we going to start, it's already half an hour over the allotted time."

Mr. Shao patted Director Wen on the shoulder and said, "The exam has started."

"The exam has started?" Director Wen looked at the detectives in this conference room through the surveillance camera.

The detectives in the room are doing everything at the moment. Some people are sitting quietly in their seats, waiting for the start of the exam. Some people simply take out their mobile phones, play games, or record something. Some people walked around the conference room, as if observing something.

In short, the criminal policemen in the conference room are doing everything, but Director Wen didn't see what kind of test this is called.

Time passed by minute by minute, and it was getting closer and closer to the end of the exam, but Lao Shao still did not appear.

"This is a bit arrogant." A criminal policeman said: Let's wait here for so long. "

Someone echoed: "Yes, we are not idle and have nothing to do."

Some people also retorted: "Wait, we were not born when Mr. Shao solved the case. I'm afraid Mr. Shao has something important to delay."

Others watched the crowd calmly.

At this time, the front door of the conference room was pushed open, and everyone looked over. However, the much-anticipated Elder Shao did not appear at the door, and a thin man appeared at the door. The man's hair was wet against his scalp, his clothes were soaked from the rain, and his shoes and pants were all covered in mud.

The peculiar shape of Jiang He immediately attracted the attention of this group of people, and they all stared at Jiang He and whispered.

It should be noted here that the criminal policemen who took the test were not wearing police uniforms. Since many people are from other places, and many cities have stipulated that the police are strictly prohibited from going out in work clothes except for official business. Especially for criminal police, wearing a uniform is too eye-catching, and sometimes it will have a negative effect on the detection of cases.

In fact, for the old fritters, they have never been willing to wear police uniforms. Most of those who wear police uniforms every day are children who have just become police officers. And this is divided into two cases:

For one type of person, the police is just a job, no different from a bicycle repairing and selling malatang. They don't want to put their lives on the job. If you are wearing a police uniform and you encounter two gangsters fighting, you are wearing a police uniform and everyone is looking at you, then you don't care. No matter, this job is lost, it may even be lost. They also have wives and sons, and they are also ordinary people.

For the other kind of people, they really love this profession, but wearing police uniforms, those criminals naturally hide far away, and the enemy is dark and bright, and they lose the initiative. The best detective will never let you know he's a cop, and when you're ready to commit a crime, only to find out that he's already targeting you.

But these people in the conference room were clean and decent even if they didn't wear police uniforms, but this Jiang He looked sloppy, and everyone really didn't want to touch him. But although they were reluctant to contact him, everyone was very curious about this Jiang He. A lot of smart people started to speculate whether this Jiang He was the content of the exam.

Some people know that every time the task force selects talents, there are various ways, and there is no logic to follow. Often when you still don't understand what happened, you are notified that you have been eliminated.

Jiang He and Wang Chao walked into the conference room together. Although Wang Chao knew that his ability was far from outstanding, he still wanted to give it a try.

Jiang He observed the entire conference room. He saw someone write in large letters on a whiteboard in the conference room: "The selection test for the members of the task force will take place between two and three o'clock."

It's already 2:45, which means that the exam will be over in 15 minutes.

Jiang He noticed that these people had no test papers at all, and Lao Shao did not appear.

"Didn't you say exams, why is there no one invigilating the exams?" Wang Chao looked left and right.

Jiang He did not answer Wang Chao's words, but continued to observe.

The exam has already started, but there are no clear exam questions on the whiteboard. Jiang He noticed that most of the people were doing nothing, and there was no atmosphere for exams. Jiang He's brain analyzed an inference. He had a 90% probability that the exam had already started, and the exam questions needed to be found by those taking the exam.

What Jiang He had to do now was to find out what the exam questions were.

What is the most important ability to become a police officer? Jiang He was thinking, he was using reverse thinking to reason.

Keen observation ability, calm reasoning ability and strong learning ability.

Criminal police need to have more acute observation skills than ordinary people, and can find the most subtle but possibly the most important clues at the scene of the crime. Criminal police need to have calm reasoning ability, can deduce a clue from a simple point, and then obtain more information from this clue. The criminal police also need to have a strong learning ability. The criminals have various occupations, and the means they use are also very different. The criminal police need to learn any knowledge and ability that may be useful in solving the case while solving the case.

So his brain sent Jiang He the most brutal execution strategy: carefully observe everything in this room.

For Jiang He, observing means remembering.

Jiang He stood at the front of the conference room, so that he could keep in mind everyone's appearance, clothes, etc. These detectives are tall, short, fat and thin, and they wear a variety of clothes. They are in their twenties and forties.

And among these people, Jiang He soon locked on one person.

The man was about thirty years old, he was wearing black clothes, and he was constantly looking at his watch at the moment. Although many of the detectives present looked at their watches, this one alone gave Jiang He a very strange feeling. Others look at the watch inadvertently and irregularly, but this person seems to have obsessive-compulsive disorder. He will take out the watch every once in a while to look at it, and he does nothing else.

Don't chat with others, don't play mobile phones, and don't sleep either.

Jiang He looked at this person carefully. To be precise, Jiang He was watching this person's shoes. Everyone came in from the rain, almost all of them had muddy spots on their shoes, and most of them had wet trousers, but this person was different. He was wearing white shoes, but they were clean, and his trousers were not wet.

And this means that this person came to this conference room before the rain fell.

The rain started around ten o'clock in the morning, and this conference room was specially used for conferences. It was not in the building of the provincial office, but a separate small building some distance away from the provincial office. In this distance, no matter how careful the person is, it is impossible to keep his shoes so clean.

Therefore, Jiang He had an 80% probability that no matter what the exam question was, it must have something to do with this person.

Jiang He raised his head, and he saw the red dots of several cameras in the corner of the wall flashing, indicating that these cameras were running, that is to say, someone was watching the many criminal police officers in the conference room. Jiang He was 80% sure that the performance of all the detectives at the scene would be seen by the people sitting in the monitoring room.

The cameras do not have the ability to collect sound, which means that the person watching the monitoring cannot hear the voices of the people in the conference room.

Action, no matter what the answer to this question, must be done by action, not by words.

So what kind of action will it take?

Jiang He reasoned while watching the man's actions. Just five minutes before the end of the exam, the man in black stood up. He got up from his seat and was about to go out the door. And if he wants to go out, he is bound to pass by the river.

"What are you going to do?"

Jiang He spoke coldly.

The man looked back at Jiang He and said, "Oh, go to the bathroom."

"I want to go too." Jiang He said.

"Go." Black clothes reached out and pushed open the door, then turned left and walked away.

Jiang He noticed that the man looked back as he left the front door.

"I don't know what the **** I'm doing, I've been sitting here for forty minutes." Jiang He said.

"Yeah." Hei Xie nodded: "I've been sitting longer than you, maybe I'm playing tricks on us."

"You go to the toilet first." Jiang He stopped.

Hei Xie nodded, ignoring Jiang He.

During the short questioning, Jiang He found that Hei Yi's answer did not match his own observations. First of all, the location of the bathroom is not marked outside the door, but the black clothes went straight to the left, which means that the black clothes are more familiar with this place.

Secondly, when he entered the door, the sound was very loud, and everyone subconsciously looked back at him, but the black suit didn't look at him, otherwise he should have known that he had only been in for fifteen minutes.

A man who kept looking at his watch and didn't pay attention to anything around him, a big question mark appeared in Jiang He's mind.

He stood where he left before the black clothes, looked back, and as far as he could see, was a trash can in the far corner. The trash can was full of garbage, but it was domestic garbage. In this conference room, it is normal for toilet paper and mineral water bottles to appear, but it is very abnormal for snack packaging or even express outer packaging.

Jiang He walked straight over.

"The exam time is almost over." Director Wen looked at the monitor and said, "What's the result?"

Shao Lao put down the cup: "Look, there is already an answer."
