Li Xiaonan, 28 years old, is a real high-achieving student, and he thinks he is proficient in a series of all the subjects that he needs to master as a police inspector, such as traceology, investigation, and criminal psychology.

Even in a world where "detective" has become a high-risk, high-paying profession that is widely accepted by the general public, he still believes that with the police station and his own abilities, he can still solve the tricks or puzzles of most criminals. Obviously, he didn't think about why "detective" has become a profession and appears widely and frequently in the public eye. Because Li Xiaonan's "spare time" is used for exercise, he also feels that the "easy chair detective" can only exist in literary works, and the real case handling needs to "walk" out the evidence and clues step by step, rather than relying only on the paraphrases and logical thinking of others.

Before Li Xiaonan became the inspector of the Polish City Police Department, he actually thought about a very real question about the world he was exposed to - why criminals are always endless. But alas, he didn't find the answer. At the same time, he is also very lucky, perhaps because he did not get the answer, so he was able to become today's "Inspector Li".

Our Inspector Li is indeed a top student, and when he was in college, he was exposed to countless ordinary or extraordinary cases, and even one of them he remembers vividly. At that time, all kinds of "detectives" had already begun to emerge, and even the first batch of "detectives" became famous earlier than Li Xiaonan thought by himself. And, along with the "detective" on the stage of Poland City, there are also an endless stream of criminals. Some of them are proficient in martial arts, and their muscles are like fictional characters in comics, and it takes five or six police officers to be able to subdue them without using guns. But in Li Xiaonan's view, it's just "so many muscles that have grown into the head". What really makes him feel troubled is actually those who are not strong in stature, or even powerless, and their eyes are full of indifference to life and the cunning of human nature.

Even cunning is not enough to describe the mystery they have set up, it is like a huge spider web that is connected from end to end, and once you are deep in it, you can't easily find an exit.

At this time, our vicious Inspector Li was frowning and observing the other three houses, and as for the extremely visually striking corpse, he naturally handed it over to the professionals under him, including the bloody and strange crime scene.

"Same arrangement." Li Xiao couldn't think about it, and picked up the manuscript left on the desk by the writer with the pen name "Coke": "They will kneel and pray, and of course the gods will not help them fulfill those selfish wishes." ”

"Day after day, they knelt down, hoping for the appearance of an ethereal and ethereal god."

"Until one day, one of the kneeling men stood up, he raised a torch, cursed, and instigated the others to burn this place full of deception."

"At that moment, a hooded figure quietly stood up from the frenzied crowd, with his head bowed and a smile on his lips, gently moving away from the people who were already arguing, and then walked out of the church door, and locked it tightly with chains.

"If anyone saw that face under the hood at this time, they would scream, because it belongs to Satan."

"The figure turned around, and there were still countless people bowing down to him in front of him. Your wish has come true. Satan spoke. ”

“...”

Li Xiaonan frowned and sighed: "These people who engage in art are a little sick, right?" ”

After a closer look, he retreated into the hallway outside 2001, sat on the stairs without a figure, and took a cigarette from his pocket and put it in his mouth.

Like most people's habits, Li Xiaonan would also come when he was thinking, and the pale cyan smoke rose from the firelight, all the way up, past Li Xiaonan's flickering eyes, and finally hit the brim of the black police officer's hat.

"Are they really the same four rooms?" Li Xiaonan's other hand kept rubbing Hu Qing on his chin, and his eyebrows were furrowed.

"Ananda, the preliminary results are out." Lao Zhong and forensic doctor Xiao Xia came to Li Xiaonan.

At the same time, several police officers hurriedly carried the body in the body bag past the three men.

Li Xiaonan nodded at Lao Zhong and Xiao Xia: "It's hard." ”

Subsequently, under the leadership of Lao Zhong, the three came to the door of the room where the crime occurred.

"Preliminary judgment, the scene of the crime is a secret room." Lao Zhong's gloved right hand pointed to the inner handle on the door of the room and said, "There is only a set of fingerprints on the handle, and the door lock is a fingerprint lock." Before we pried the lock open, there was no sign of breaking the door lock, so we were able to tell that the fingerprints on the handle belonged to the deceased. There is no gap between the door and the frame, the only gap is between the door and the floor, which is only 1.8 cm. ”

"Look at that again." Lao Zhong raised his chin at the window above the desk: "The inside is also locked, the window is a structure of two glasses pushing outward, the window and the window frame, the two glasses are tightly seamed, there is no trace of silk thread passing through or rubbing." ”

"And the sound insulation and airtightness of this room are very good, and even when the doors and windows are closed when there are many people, the people in the house will feel deprived of oxygen within a few minutes." Lao Zhong took Li Xiaonan over a pool of blood and walked to the desk: "Except for the living room, there is no carpet in every room, maybe because the sound insulation is particularly good." The body was found next to the fallen chair, and from the position, it is possible that it had fallen from the chair. ”

Lao Zhong stretched out his finger and pointed to a pool of blood at the feet of the three people: "Judging from the blood residue at the scene, the amount of bleeding is a bit too much, and the blood here has begun to stratify, the blood in the lower layer touching the floor has coagulated, but the blood in the upper layer is still bright red..."

"Judging by the taste...", the forensic doctor Xiao Natsu interrupted, "I mean the smell... It's not like all the blood belongs to the human being, that is, the dead. ”

Li Xiaonan nodded, habitually took out his pocket, and took his hand out of his pocket again, smoking was not allowed at the scene of the crime.

"The ceilings in this room are high, isn't it a little too high?" Li Xiaonan raised his head and looked at the empty ceiling except for a beam in the shape of a rectangle that stood alone in the air.

Lao Zhong replied, "That's true, but I checked the other three rooms, and they were all the same height. ”

Li Xiaonan's eyes narrowed slightly, as if he was looking for something, and the structure of this room always made him feel a little strange beyond words.

"Then I'll briefly talk about the deceased, and then I'll go back for a further autopsy." Xiao Xia's crisp voice pulled Li Xiaonan's thoughts back.

"The preliminary judgment of the time of death of the body should be between nine and ten o'clock this morning, and the cause of death was due to the fragmentation of the skull caused by the blow to the head with a heavy object, resulting in intracranial hemorrhage, and finally death." Xiao Xia said, looked around, as if looking for something, and then continued: "But the inference of the murder weapon has not yet been made, and it can only be judged by the shape of the wound that it is a heavy object similar to a sphere, and it has not been found at the scene." ”

"Good work." Li Xiaonan signaled that he understood, and said: "After I go back, I will first hand over the blood test results and the comparison of fingerprints with identity, and I will now go and see how the confessions of the three informants are doing." ”

“...”

"Finished recording?" Li Xiaonan walked out of the apartment building, lit a cigarette as he wished, and said to the girl in front of her, who seemed to be a little too shrewd: "You won't let my suspects run away, will you?" ”

Zhao Yinglu turned his head, put on an expression of looking at a fool, looked at Li Xiaonan, and said weakly: "Don't worry, none of them can run, they were all pulled away by Xiao Yang and them, please go back to the bureau and drink a glass of water first, right~ Inspector Li, Li Si."

。 ”

"Uhh Li Xiaonan spit out a puff of cigarette, stretched out his hand to take the confession materials handed by Zhao Yinglu, sat on the steps at the door of the apartment with a big grin, and asked while flipping through it, "What do you think?" ”

"The guy with the pseudonym 'Cola' was always nervous, and several times wanted to go back to room 2001 to pick up some manuscripts, saying that it was important to him. He also repeatedly inquired about the specific situation of the crime scene, and asked the east and west to engage in some obscene and suspicious small actions. ”

"On the other hand, the one called 'Purple Dragon'... Well... How to say it, except for asking: 'Shouyang' is dead, of course we didn't answer him. After that, he was very cooperative, the kind that knew everything. ”

"The one called Xiao Xue... Belle. She behaved a little too normal, including what time she ordered the takeout for the writer and remembered it very clearly. Of course, her reasoning makes sense, she has a notepad full of things she has done and things to accomplish. Her voice was soft, but it did contain a slight tremor that was suppressed. ”

"So you think Xiao Xue is fine?" Li Xiaonan stepped on the cigarette butt and held it in his hand.

Zhao Yinglu was a little hesitant when asked like this: "Probably, she is really normal, I have seen people for many years, my eyes are rulers!" ”

"It's not just a casual talk."

“...”

"Ananda, when I was leaving just now, I found that the door of room 2001 had traces of being pried in advance, and the technique was very professional, and I might not have found it on a whim." Li Xiao glanced at the text message sent by Lao Zhong on his mobile phone, and combined with the content of the confession he had just read, he also edited a message for Xiao Xia.

"I'll ask my people to take those takeaways and test them to see if there are any sleeping ingredients similar to sleeping pills."

Li Xiaonan stood up, patted his pants, and said to Zhao Yinglu: "Let the administrator of the apartment make a copy of the surveillance at the door, from today to a week ago." ”

"Leave them for 24 hours first, and the bureau will still have enough food and drink."
