Seeing the two notes, Wu Duan's first reaction was to laugh, and the second reaction: This guy can't be a joker Of course, in addition to the literal content, Wu Duan also noticed some characteristics of the note itself.
The note is not handwritten, but is made up of a collage of words cut out of a newspaper.
It is a very common technique in mystery novels.
"Reasoning fan," Wu Duan said.
"On paper."
Yan Sixian expressed disdain, "Although this technique is used badly in novels, it is not common in reality, because criminals who will leave messages in real cases are rare."
It's too late for criminals to evade the police, how can they still have the heart to deliberately leave a message, only the kind of criminals who are particularly arrogant and want to show off their skills will choose such a method. ” "I don't think so."
Wu Duan put forward a different view.
"Oh" "After all, the note is not reserved for the police, whether he wants to show off his skills, or purely to prevent the two words in the text of the Harmony Prevention Officer will be replaced by tg, which will cause you the inconvenience of reading, I am very sorry for the blockage, and it is hard to say now.
If it's the latter reason, don't you think he's cute?"
Wu Duan kept staring at the two notes with interest as he spoke, and finally simply put on his gloves and took the notes out of the evidence bag.
"Discovery," Yan Sixian asked.
"Nothing, a little fur."
"Tell me about it."
"Our big thief, I'm afraid I have obsessive-compulsive disorder."
Wu Duan took out a piece of A4 paper from the printer paper tray in the office, stacked it with two strips of paper, and said while gesturing: "The width is the same, and the white paper used for pasting words is cut from ordinary A4 paper."
A sheet of A4 paper is divided into three equal parts, evenly sized.
The edges of the cut paper are smooth, and it takes a lot of care to see the cuts.
If that's not obsessive-compulsive, then look at the words on it.
The characters were cut from newspapers, and each word was cut by sticking to this side, and the small pieces of paper cut out were exactly the same size.
When pasting, the distance between each word is even, there is no warping at all, and there is no excess glue at all.
I can even imagine our thief sitting at a table, neatly dressed and with cleanly trimmed fingernails.
He turned on the lamp, picked up the cut words with tweezers, smeared glue on the back, and used a ruler to compare each word up and down to ensure neatness, and in the process of comparison, he might also use something like a toothpick to adjust the position of the words. ” Yan Sixian chuckled, and Wu Duan looked at him suspiciously.
"Team Wu's imagination is quite rich, and the profile of this character is like making a movie."
"You can just make an axe and throw bricks and bricks in my class," Wu Duan shrugged, "You are a professional in this area, and if there is something wrong, just mention it." ” "No, that's good.
Let me add a little. ” "Listen up."
"I've sifted through the last two years of theft.
Exclude the thieves who have been caught, exclude the violent lockpicking, and then exclude the theft of valuables such as jewelry and watches in addition to cash, and the rest are either too little stolen, and it is more appropriate to describe it as stealing chickens and dogs, which does not match the handwriting of our big thief, or it is a snitch."
"Snitch" "Ropes were tied to the top floor of the building and hung down, specifically stealing high-rise residents who did not have security windows.
This kind of theft method is in its own right, and it has nothing to do with our technical locksmith.
Therefore, the first thing that can be determined is that the known theft cases with police records have nothing to do with the thief we are facing, he only steals TG, and extends it appropriately, at least his theft object will never choose to call the police for some reason, and he directly avoided confrontation with the police from the root.
He's smart, at least much smarter than the average thief.
At the same time, he has a lot of self-control.
Never taking a piece of famous watch jewelry worth hundreds of thousands of dollars is proof of this.
Those things seem to be valuable, but the sale of stolen goods is a big problem, and it is easy for the police to find out, and many thieves just show their feet in the sale of stolen goods and end up caught.
The reason is very simple, and thieves understand the risks, but people are so difficult to control greed, and people are so weak in the face of temptation.
Those thieves who were finally caught because of the sale of stolen goods, which one of them didn't move me when facing famous watches and jewelry, how could I be so unlucky, how could they just catch my mind.
Only we, the thieves, never had this mind.
Even if his target is not to store a lot of cash at home, it is only tens of thousands of yuan, and what is stored in the safe with these tens of thousands of dollars is jewelry worth millions.
This kind of self-control can be said to be amazing. ” Wu Duan nodded in agreement, but it was only in agreement, unlike in the past, Yan Sixian's analysis did not surprise him.
Wu Duan waited for the following.
Yan Sixian continued: "Self-control, as well as the choice of specific theft targets, after all, are subjective factors, personal choices, nothing, the difficult thing is how to find those TGs Pay attention to the probability that a total of 39 TGs have been killed in the past two years, and 33 of them have been stolen from their homes.
More than eighty percent, the accuracy rate is about to catch up with the patrol prevention and harmony group.
Have you ever wondered how he could know so accurately which people were TG?"
Wu Duan's face was very solemn, and he was silent for a long time before he said, "I have a not-so-good idea. ” "Don't say it," Yan Sixian showed a rare nervous mood.

In addition to being nervous, he was scared and shuddered.
"There are some things that can't be said nonsense."
Yan Sixian said.
So Wu Duan said in a low voice: "The world is as black as a crow." ” His meaning is already very clear: maybe there is no clean place, there are no clean people, the thief did not deliberately choose TG to steal, as long as it is an official, he will steal, so that it can also achieve an accuracy rate of more than eighty percent.
This thought made the scalps of the two of them tingle, they were like people walking alone with torches, there was chaos between heaven and earth, they did not know where they came from, they could not see the end, they did not even have a torch of the same kind, and they could be swallowed by unknown things at any time.
Yan Sixian understood the deep meaning behind the secrecy of this case, and when he was the only one who understood it, he didn't feel anything, he was not optimistic about the world.
But he could see Wu Duan's fear.
This made Yan Sixian worried.
But Wu Duan's fear was only for a moment.
"Let's not talk about that yet."
Wu Duandao.
"Okay."
The two unveiled this article very tacitly.
They can't afford to lose hope.
Without hope, all their wisdom struggles, all their lives hanging by a thread, there is no meaning, and they don't have to explore any truth, just wait for the darkness to spread to the sky, wait for destruction.
Wu Duan got up and made himself a cup of tea, and he asked Yan Sixian again, "Do you want it?"
Yan Sixian said, "Yes." ” So Wu Duan made Yan Sixian another cup.
He needed to do something to get himself out of that conspiracy theory trap for a while.
Even, after making tea, Wu Duan paced to the window and looked at the dead trees in the police compound for a while, as well as the traffic at the entrance of the police station.
Today's weather is fine, and it is one of the few sunny days in winter.
Standing by the window, the sun can shine on your body.
Wu Duan stood in the sun and thought nonsense, he thought: People should bask in the sun more, so it is difficult to have any dark thoughts, I don't want to harm others, and it is not easy to think badly of others.
During this process, Yan Sixian maintained the sitting posture just now without saying a word, and his right hand flicked the black and gold rope buckle on his left wrist from time to time.
There was a knock on the glass door of the two's office.
The office of the first team is divided into two parts by a glass curtain wall, the smaller space is the office area of Wu Duan and Yan Sixian, and the rest of the open space is the office area of the criminal police.
At this moment, the two of them closed the door and discussed the matter in their own office area.
Wu opened the glass door, and the criminal policeman outside the door said, "Take out, don't you need to order it?"
"No, thank you, let's go out to eat."
Yan Sixian rushed to answer.
With that, he had begun to put on his coat.
After putting on his coat, he put all the case files back in a brown paper bag and tucked them under his arm.
Wu Duan also put on his coat, and the two went out together without saying a word.
Until he got into the car, he let out a long breath.
"You know this, I know, and the above few people know, it's enough.
The following must be kept completely confidential.
Wu Duan said solemnly.
"But just in case" "No in case."
Wu Duan looked at Yan Sixian deeply, "The truth is not enough, sometimes the truth destroys hope and courage."
Besides, we are not alone, at least there is still Zhao Ju" For the first time in his life, he admired Zhao Ju in his heart.
If the environment they are in has been completely rotten, Zhao Ju can still create a relatively clean space for them, so that they can do practical things without worries and devote themselves to solving the case.
He had to admire such a person.
"Even if the worst outcome is the truth, we have to think about the good, and the request for secrecy of this case may be based on the same considerations as us."
"Perhaps."
Yan Sixian grasped the key point.
Probably not.

Perhaps they have ulterior motives, and secrecy is often linked to conspiracy to frame and kill.
But Yan Sixian didn't finish his words.
His car drove out of the gloomy underground parking lot.
The sunlight poured down from the skylight, and the reflection of the snow on the roadside pierced Yan Sixian's eyes.
Wu Duan took out his sunglasses from the utility box between the two of them and handed them to Yan Sixian.
Yan Sixian shook his head, "I won't wear it today." ” Wu Duan silently put away his sunglasses.
Yan Sixian parked the car in front of his hotel and entered a restaurant box with ease.
They need a quiet place.
When the waiter saw Young Master Yan, he was a little scared.
Yan Sixian said: "Tell the back kitchen, the dishes are the same, I pour the tea myself, you don't have to stay here." ” The dishes were quickly served, and when only he and Wu Duan were left in the box, Yan Sixian said: "Continue to talk about the case, I just said where it came from."
As if he was afraid of the heavy atmosphere, Yan Sixian beckoned again: "Say while eating, you taste this, I will help you order a glass of appetizing sweet wine." ” Wu Duan took a sip of amber wine.
The mellow and rich aroma of the wine oozes out little by little from the sweet and silky taste, which is really appetizing.
Wu Duan sent a mouthful of food to his mouth, and did not forget to answer Yan Sixian's question: "You just said, how did the thief find out who is TG?"
"Let's put this issue aside for the time being, I'll talk about the next problem first, unlocking.
The level of unlocking of thieves is the top in the industry, and it is not easy to open fingerprint locks alone.
Thanks to learning from you for a while to unlock, I also have some understanding of door locks, now there are three types of commonly used door locks, A-level lock cylinder, which is more than ten years ago was still commonly used word lock cylinder and cross lock cylinder, the mutual opening rate is extremely high, if you are lucky, you don't need to learn the unlocking skills, you can directly poke it open with wire.
Of course, A-class cylinders have been phased out.
The B-level lock cylinder is slightly more advanced, which is the door lock and tablet key of our office.
C-level lock cylinder, also called super B-level no way, businesses just like to make a fuss about the name, our police arsenal, gun arsenal is C-level lock cylinder, supporting the crescent moon multi-row key.
These three kinds of lock cylinders, although the level of anti-theft is different, but the principle is the same, the more complex the key structure, the more complex the arrangement, the deeper the tooth marks, the better the anti-theft performance.
As a result, they can all be unlocked by technology, which can be easily handled by qualified professionals, but the more difficult ones may require a little more time.
Fingerprint locks are different, although there are also keyholes on fingerprint locks, which can also be opened by keys, but the keyhole itself is designed to be relatively hidden, and it takes some time to find and open the obstructions on the keyhole.
Some locks are also smarter, and when the keyhole shield is opened, they will send a message to the associated homeowner, and the homeowner can call the police in time even if he is not here.
You have to believe in the police system in the area, and the arrival of the 110 police can be controlled within 5 minutes.
Thieves don't take this risk, so even if they can open the fingerprint lock through technical unlocking, they won't choose someone with the fingerprint lock installed.
The thieves we have to face are different, 27 of the 33 TG households stolen by him are installed with fingerprint locks, including fingerprint locks with extremely high anti-theft levels and tens of thousands of yuan.
None of them received the message that the keyhole occlusion had been opened.
In other words, what we have to face is not a thief who picks the door and locks in the traditional sense, but a real high-tech that can crack the most secure door lock on the market from the fingerprint and password level. ” After saying this pile of theoretical knowledge, Yan Sixian poured half a cup of tea.
Wu Duan grabbed a piece of chopsticks of meat and was about to send it to his mouth, but seeing that Yan Sixian was a little pitiful, he sent the meat to the plate in front of him.
"Don't just talk, eat something."
Wu Duan swallowed the food in his mouth, wiped his mouth, and said, "Could it be that we think about it complicated, if the thieves can get their fingerprints?"
For example, he is a little person next to these TGs, and no one notices or he is an official himself.
That would explain why he stole a target, and he might have had a way of knowing the TGs. ”:
