The hottest part of the day is the afternoon on a hot summer day. And now, in the small house of Professor Wang's house, the officers in police uniforms are looking for something everywhere. Everyone's body is already wet.

That's right, everyone is looking for everything related to "books". Even the deputy director, the instructor and I were all trying to find it in the house, and the only thing that didn't need to be done at the scene was probably the colleagues who were responsible for guarding the scene outside the guard belt at the door and expelling irrelevant "melon-eating people" by the way.

My back hasn't been done since I came back from the morning meeting, and now, the sweat on my body can probably be wrung out of the water. I really feel like I'm back today, why I'm at work today. HOWEVER, THIS ASSUMPTION IS ALSO FUTILE, BECAUSE I AM THE COMMUNITY POLICE OFFICER IN THIS COMMUNITY, EVEN IF I AM OFF TODAY, IF SUCH A CASE OCCURS, THERE WILL DEFINITELY BE A "FATAL SERIAL CALL" AND CALL ME HERE. No way, this is the duty of the people's police.

I finally couldn't help it, I bent my waist for a long time, I couldn't stand up, and while resting a little, I couldn't help but sigh: "There may be no money in the scholar's family, but it is absolutely impossible to have no books!" Books are the greatest treasure of a reader! In the vast sea of books, how to find it! ”

That's right, since Professor Wang is a university professor, the most important thing in his family is indeed books. A variety of books. Not to mention his professional books on history, there are also a variety of other types of books, such as politics, medicine, geography, literature, etc. The whole two-bedroom room, from the study to the bathroom and even to the living room, is full of books. If these books are stacked vertically, it is no exaggeration to say that I estimate that they can be stacked at least 3 or 4 stories high. I see that he reads so much, there are so many books, and most of his retirement salary is used to buy books.

If you think about it carefully, it's not wrong that as a retired old professor, his salary is actually not low. However, he does live a frugal and simple life. Eat at most one vegetarian and one meat every day, although there is an air conditioner at home, but I would rather turn on the fan than turn on the air conditioner. When the weather was just starting to get hot, when I visited his house regularly, I also mentioned to him that he should turn on the air conditioner to prevent heatstroke, after all, the elderly are prone to heat stroke. Who knew that when I mentioned it, he always shook his hand while shaking his fan with a smile and said to me: "Oh, Xiaofei, you don't understand." We are weak in the elderly, and we are old enough to turn on the air conditioner, which is easy for moisture to enter the body, and in summer, it is good to sweat a little, and it is hot to get hot. You young people don't always try to blow air conditioners, and get sick when you get old. "Later, he even mentioned to me the statement about human dampness in the "Yellow Emperor's Neijing", which scared me so much that I didn't dare to say more. However, there is one thing to be admired, part of the money he saved was used to buy books, and part of it was used as a fund for public lectures for children in the community, and he bought a lot of history books suitable for children to read out of his own pocket and put them in the neighborhood committee library for children to read for free. I have to say that people who have such a noble spirit now are still worthy of admiration.

As soon as I thought of this, my original tired mood was swept away, and a trace of firmness emanated from my heart. I silently looked at the photo of Professor Wang on the desk, and secretly swore to myself that I must find out the reason and let Professor Wang go with peace of mind. After all, now the forensic on-site investigation, because of the particularity of the case, it is impossible to find out whether it was a murder or an accident, so it is even more important to let go of all clues to find out the cause of Professor Wang's death.

Just as I was thinking nonsense, Zhang Chu came over and patted me on the shoulder: "Xiaofei, young man, you have to hold your breath." He said to me gently, "Your dad is great at that." More than 20 years ago, I worked with him on a case in which your father went to dozens of plastic bag factories in order to track down a plastic bag containing a broken body, and it took several months to find out which factory produced the plastic bag. You also know that in those days, there was no Internet, only relying on the soles of the scouts' feet to check one by one. ”

I was embarrassed and said, "Uh, Zhang, really? My dad is so good? Zhang Chu was surprised: "Didn't your father tell you?" I could only quickly reply: "My father and my mother, including my grandparents, rarely talk about cases at home." My father said that it was for confidentiality, even if I graduated from the police academy and officially became a regular after the internship period, he rarely appeared in front of me. ”

"Well, yes, Lao Cheng is very principled, good comrade." Zhang Chu smiled and replied to me.

"Zhang! Come on, there's a discovery! Suddenly, one of Zhang's team members said to him in a loud voice.

The people in the house immediately gathered around that place. I saw that in one of the compartments of the bookshelf, a brand new brown paper bag was found. Inside it seems to be a book.

"Great! Open on! Zhang Chu couldn't hide the excitement in his heart, and hurriedly said. The team member opened the brown paper, and sure enough, it was a book written by Professor Wang.

However, there are only 8 books in it. Zhang Chu was very strange: "Why is this all?" Aren't the books generally published in large print runs, how can this be? Zhang Chu immediately said to a team member: "According to the information of the publishing house above and the book number, check how much this book has been printed!" Fast! One of the team members immediately took out his mobile phone.

While they were discussing, I picked up one of them, looked at it, and oh, there really was an "X" on it. When he gave me the book before, I was in a hurry, and when I got home, I threw it on the cabinet. Didn't read the title either. Now let's take a closer look at the title of the book, "The X-Files in the History of Local SH".

Yo, the name is quite catchy. It can't be inspired by the American drama "The X-Files", and the title of the book you wanted, right? Professor Wang is really not such a sold-fashioned person as he remembers, at least he knows about the X-Files. My impression of Professor Wang changed suddenly.

Not long after, the team members under Zhang came back to report. And shocked everyone present.

The group member said that the publishing house confirmed that the book was actually printed by Professor Wang at his own expense, and that the book number was also obtained by a friend he knew. In total, only ten copies were printed!

Yes? What, only ten copies were printed?

Zhang counted them and found that there were only eight of them, so what about the remaining two?

At this time, the team members who first discovered the kraft paper found a piece of paper sandwiched in the kraft paper, and when they looked at it, it turned out to be a receipt: it read: Thank you Professor Wang for donating a new book to Fudan Library.

Zhang Chu immediately knocked on the receipt and said, "It didn't take much effort to get it." Well, one of them is available. What about the other one? This may be difficult, who knows who he gave it to. After all, he has so many students and friends, do you have to check them one by one? When his team members heard this, everyone immediately felt obviously heavy. Isn't it heavy, all of a sudden, the workload has become larger!

I thought about it for a while, and said to Zhang: "Zhang, you don't need to check the other one, Professor Wang gave it to me." ”

All of a sudden, the focus of the audience turned to me again. It's as if I'm an alien who appeared out of nowhere.

Zhang immediately said to his subordinates: "Lao Zheng, you go to the Fudan Library and bring the donated book." Then he turned to me again and said to me: "Xiaofei, work hard, go home and find that book and bring it over, now the case is too complicated to let go of any clue!" ”

In this matter, a member of Zhang's team also said: "Zhang, these books have just been preliminarily tested, everything is normal, they are all brand new, they have not been opened, and there is no physical evidence in them that can be extracted." In addition to the fingerprints, it is estimated that they are either printing factory workers or Professor Wang himself. ”

Zhang Chu looked at me again and said to me, "Xiaofei, go, go and come back quickly." It seems that the clue is in these two books, and I don't know which one it is. But, at least we have a direction to investigate. ”

"Yes! Zhang, I promise to go and come back quickly." The deputy director gave me the key to the police car, and I was not polite, I rushed downstairs with the key, and just got into the police car and was about to start, the secretary of the neighborhood committee stopped me and asked, "Xiaofei, have you found out the murderer?" ”

I was so angry and funny, why these "melon-eating masses" were more curious than the TV reporters, I only stuck out my head and said: "This is a public security secret, you can't say it, you, don't worry, when you can say it, I will report it to your neighborhood committee in time, you are patient and wait." By the way, there are too many onlookers, and it's time to cook dinner soon, so let them disperse quickly, go home and buy vegetables to cook, otherwise there will be no vegetables to buy in the vegetable market! "It's still my words, or maybe it's because I've been a community police officer here for a long time and have appeal, and sure enough, a lot of onlookers left at once. The big head of the guard belt outside gave me a thumbs up. I rolled my eyes at him, then pulled off the police car and drove home.

Not long after driving, when I arrived at an intersection, my mobile phone rang, and while I was waiting for the red light, I took a look, and it turned out to be my father. He rarely calls me when I'm at work. I still put on the Bluetooth headset and connected to his phone.

On the phone, my father's voice came: "Xiaofei, let me tell you, that case is not simple!" From now on, you have to work with 120,000 points of spirit and cooperate with the work of Zhang! ”

What the? I never ask my working dad why he is suddenly so serious today? At this time, my father said another sentence, which made goosebumps rise again in my body: "Xiaofei, this case has begun to be complicated, and I suspect that it will be dangerous." If you continue to cooperate with the investigation, remember to go to the office first to apply for a gun. Even if you don't have a gun, you can't leave your eight-piece suit, especially the slinger and blast spray! ”

What the? What's going on? Why did my dad ask me to go back to the office and apply for a gun?
