Author: The bear skimming the treetops

It seems that Yan Jianbo is very interested in traveling.

However, this is not just a hobby.

Many years ago, Japanese spies began to carry out "illegal surveying and mapping" activities in Northeast China and other places, all in preparation for future military aggression.

Yan Jianbo may have been one of the many surveying and mapping personnel at that time, or perhaps his admirer.

He seemed to be reminiscing about the "glorious" years of the past.

At this moment, Fang now vaguely felt that he was close to the truth. With Yan Jianbo's almost obsessive-compulsive personality, why would he let two travel books be placed separately?

When Zhang Xinhua and Wang Weizhong rushed back from Yan Jianbo's office, it was already close to four o'clock in the morning. As soon as they entered the room, they saw that the ground was piled with books and it was a mess. They were both stunned.

Lao Ji looked at the two officers with some embarrassment. In fact, he wanted to remind Fang to pay attention to protecting the scene, but after thinking about it, he swallowed the words in his stomach. After all, he could not figure out the details of this young man.

Fang now raised his head, looked at Zhang Xinhua and Wang Weizhong and smiled lightly.

Zhang Xinhua saw that Fang's face was now full of exhaustion, so he asked Wang Weizhong to rush over to help.

Wang Weizhong was obviously stunned for a moment. The deputy team leader had not allowed him to have access to these books before.

"Senior brother, please help single out all the books with library cards!" Fang was not polite now. He had to complete all these tasks by himself, and he might not be able to make enough time.

Not long ago, he discovered that there were signs of being torn off on the back cover of the Book of Famous Mountains and Scenic Spots in the World, but what was torn off was not the paper of the book itself, but something that was later glued to the pages.

He then looked through several other books and found that not all of them were purchased by Yan Jianbo himself, but that a considerable number of them were borrowed from Lincheng Library or bookstores.

Fang now speculates that the thing that was torn off was probably a library card.

He had used this kind of library card in the library of the police academy before.

The rules are: after readers select the books they want to borrow, they take out the library card inserted in the paper bag on the back cover, fill in their name, major, and student ID number in the designated position. Then give the library card to the administrator.

, you can take the book away.

When returning a book, the administrator will register it and then insert the library card back into the book. If a book is borrowed many times, the library card will fill up quickly, so it needs to be replaced regularly.

Fang has now discovered among the books library cards from Lincheng Library and five bookstores.

Although the styles of these library cards are different, the material and color of the paper bags used to hold the library cards are difficult to distinguish, making it impossible to determine the origin of this book about famous mountains and scenic spots in the world.

As expected of an old agent, Zhang Xinhua immediately saw the clue and asked, "Now, do you mean that Yan Jianbo destroyed this library card at the last moment?"

"Deputy team leader, my initial judgment is this: The reason why the Biography of Women seems to have moved is actually because Yan Jianbo accidentally touched it when he took out and put back the Records of Famous Mountains and Scenic Spots in the World. The matter was urgent at the time, and I think he should

I didn’t pay attention to this problem.”

Zhang Xinhua nodded. According to this, Yan Jianbo still wanted to destroy this library card at the critical moment of life and death, which shows that the library card has special meaning to him.

"Now, this clue is very important!" Zhang Xinhua said, "We just asked Yan Jianbo's colleagues at the foreign bank where he works, and they all said that this person is very smart and capable, and he is easy to get along with. He has no contact with outsiders except for work needs.

He is often seen taking books to foreign companies. Therefore, libraries and bookstores should be places where he often goes, and the possibility of using these places to convey information cannot be ruled out."

Zhang Xinhua led a large number of people to find the address of the manager of the foreign bank directly based on the household registration information of the police station, and brought him to the foreign bank. Based on the personnel information of the foreign bank, he grabbed more than ten colleagues of Yan Jianbo from their beds overnight and conducted a detailed investigation.

Ask for troubleshooting.

Fang now took the confession and read it carefully, and had to admit that there was nothing suspicious about Yan Jianbo. This guy didn't even have any correspondence.

There aren't any valuable clues even in his office.

But the more this happens, the more it shows that there is something wrong with Yan Jianbo.

Fang Jin thought for a while and then said: "Deputy team leader, places like libraries and bookstores are good places to pass on information. The simplest way is for Yan Jianbo to put the information in a book, and his companions will then put it in

Information is taken away.

Of course, there are risks in this. In order to ensure that the information is not discovered by irrelevant people, Yan Jianbo's companions must take away the information in a very short period of time. Therefore, it is very likely that the two of them will appear in the library or bookstore at the same time.

among.

Wait until daybreak and check these bookstores and libraries one by one, maybe someone will have an impression of Yan Jianbo."

"Not bad!" Zhang Xinhua nodded. He had carefully considered this matter on the way back. In addition to the radio station, Yan Jianbo must go out to transmit information, either by contacting people or using dead mailboxes.

Currently, we are searching along Yan Jianbo's upline. Another way of thinking is to find Yan Jianbo's downline, that is, where he got his information from. This is also very critical, because this downline is most likely to be planted by Yan Jianbo.

Mole in the military, government or other key departments.

At this moment, an action team member came from outside and reported that the telecommunications team inspected the broken radio station overnight and concluded that the frequency of use of the radio station was very low and basically had not been used. It could even be said that

Brand new.

As for whether any abnormal radio waves were found in this area in the listening records, the telecommunications team said it was impossible to investigate.

Fang Jin and others frowned slightly after hearing this.

This result is obviously unsatisfactory.

Even though this radio station is brand new, it does not mean that Yan Jianbo has not used other radio stations before.

At this point, the way to trace clues through the radio seems to be dead.

Zhang Xinhua looked at Fang Jinjin: "Have you read all the books here?"

Fang Jin smiled bitterly: "There is still half a bookshelf!"

"In this way, let Wei Zhong check it out together. After that, take a short rest, and we will go to the library and bookstore early in the morning."

With Wang Weizhong joining in, half of the bookshelf was checked out in less than half an hour.

In fact, although Wang Weizhong looks tall and thick, he actually graduated from a serious police academy and has a much higher education level than Zhang Xinhua.

Later, other team members restored the books to their original state.

Although Fang could rest now, he didn't feel sleepy at all.

It gets bright early in summer. Although it's only five o'clock, the sun has already risen above the horizon.

A team member bought breakfast, and Fang and others had a simple meal in the corridor.

Although this night was hard, there was always a glimmer of hope.

However, Fang now also knows very well that whether clues can be found in libraries and bookstores is still unknown.

Because this is all based on speculation.

In fact, the places where Yan Jianbo delivers information do not necessarily have to be libraries and bookstores.

He can deliver the information to a dead mailbox in advance, and then mark any specific place at his residence or on the way to work with a specific mark.

When his companions see this mark, they will go to the mailbox to get the information.

In doing so, the two parties do not need to come into contact at all, which can minimize the risk.

Of course, doing so will also make it impossible to trace this clue at all.

As for the truth, I'm afraid you still have to go to a library or bookstore to check it out.
