Detective Training Manual

And around here... there is nothing to see.

It's the subway.

For ordinary office workers, it can be said to be a familiar place. You have to squeeze every day. When you close your eyes, you can automatically construct a subway station structure in your mind.

Now, the cordon was open, and the passengers all sat back. Some people looked at the police curiously, and the crowd was whispering.

Zhou Yan seemed to think of something suddenly.

Because he saw the word [12] written on the door just beside the ladder.

This [12] is actually not written on the train, but on the baffle of the subway platform.

People who often take the subway must know how this [baffle plate] works.

But to be on the safe side, I still have to explain.

General platform baffles are made of toughened plastic and are transparent, but there are actually doors on the baffles.

When the train stops, the [door] of the train will automatically correspond to the [door] of the platform baffle.

A person wants to enter the train. First, he has to step over the door of the baffle first, and then the door of the subway, so that he can enter the carriage.

At this moment, the subway door in front of Zhou Yan slowly closed. With a long sound, the subway drove away, leaving only the transparent baffle and the [12] mark on the baffle door.

"Can you be sure that the bag of fashion money is placed above door 12?" Zhou Yan asked suddenly.

The plainclothes policeman who was staring at Madam Qian nodded, "Of course I can be sure."

"Hmm... Then, can you be sure that the corresponding car at gate 12 of the previous platform, and the car corresponding to number 12 on this platform, are the same cars?"

"Huh?" The plainclothes policeman was taken aback: "Uh, I didn't understand too much."

"That is to say, will the two stations have different locations where the trains stop? I have seen a subway station that is obviously a few years old, and this subway station seems to be new.

So will there be a difference in the length of the new and old subway stations? Will the carriage corresponding to gate 12 of the previous subway station arrive at this platform, and the corresponding carriage will become gate 17? . "

"This..." After listening to Zhou Yan's words, Lao Guo seemed to frown: "Brother Zhou meant, could it be the travel bag with money, but it was actually on the other carriages? ?"

"It's just an idea." Zhou Yan nodded.

"Hi~" Lao Zhou was also stunned. Everyone has been to the subway, but he really doesn't know whether the doors of the new subway and the old subway correspond one-to-one.

Perhaps, a dozen years ago, the subway had 18 cars, but now the subway has 20 cars?

Are the subway doors one-to-one correspondence?

As a member of a serious crime team, he had never even considered this issue. For a while, Lao Guo felt that he was still not professional enough.

But he didn't know it was okay, wouldn't there be subway staff beside him.

Lao Guo immediately called a staff member over to ask.

And the staff's answer, that can be more professional, wow wow a lot of talk.

To sum it up, there are only three types of subways, and the subways of the same route must be of the same type. The doors corresponding to subway stations are all one-to-one correspondence. There will be no Zhouyan. The kind of situation described.

After Zhou Yan heard it, he also nodded.

"Well... the car and the door are in one-to-one correspondence... When driving, there is no possibility for the people in the car to go out, and the station is always monitored by the police. As a result, I think The only way to do anything is during the time when the train enters the subway tunnel."

Zhou Yan thought, looking at the dark subway tunnel through the baffle of the platform...

In that black gurgling...what happened?

......

According to this idea, the best way is to let the subway responsible unit block the subway line, and then send a group of policemen into the tunnel to conduct a little carpet search.

Unfortunately, this is impossible.

If we say that there is really a den of human trafficking in this subway, maybe the subway will be blocked for a while, but you have to say that it is to unravel the'mystery of money being swapped' and stop the subway. That would be a bit unreasonable.

You have been out of service for one day, maybe you have lost a lot of money for the subway ticket~www.readwn.com~Who will pay the money then?

Even if the question of money is thrown away, the public opinion can't stand it. What a mess, if a rich person loses five million, you stop the subway?

Then you don’t care about the deduction of wages when we hit the workers on the night shift?

Take this to the cusp of the storm in minutes. ,

Therefore, the case at this moment suddenly reached the point where it couldn't go on.

In desperation, the police can only be very depressed, and put forward the suggestion, "Let’s go back, if the kidnappers really get the money, then he will definitely call."

And this suggestion is really difficult for detectives to accept, because it is equivalent to saying, ‘then~ these two detectives are not recruited, so we can only be led by the nose by the kidnappers. ’

Zhao Shengrui had a look of iron, but he was also helpless, because he really couldn't explain this matter.

As for Zhou Yan... his mental fatigue now seems to be slightly relieved, and his thoughts gradually become more active. In his memory, Mrs. Qian’s various behaviors, Mr. Qian’s reactions, and the police's treatment of this kidnapping case His attitude, and the whole process of paying the ransom afterwards, are no longer a pool of stagnant water. But it flows slowly, converging into a stream, flowing in my mind with a cold feeling, faster and faster.

"Okay~ Let's go back, as long as it's okay." Madam Qian still doesn't want to care where the 5 million went, she still does what she always did, just caring about the safety of her children.

Yes... it is normal for a mother to only care about the safety of her child.

Zhou Yan was startled suddenly.

He seems to have caught something...

The "something wrong" that had been in his mind all the time became clear in an instant!
