8:00 a.m. sharp the next day, Polish City Police, Inspector's Office.

Li Xiaonan woke up from his desk with a yawn, and there were two reports in front of him, one of which proved that more than 60 percent of the excess blood that appeared in the room at the scene of the crime did not belong to the deceased, but to the treated animal blood, and I don't know how to get rid of the unique smell of animal blood.

Another report proved that the fingerprints on the inside doorknob of the room at the scene of the crime belonged to the deceased. And additionally, it was also noted that the several takeaways delivered to the trace examination department yesterday did not contain sleeping ingredients.

"It's really a secret room..."Li Xiaonan muttered to himself in a low voice.

The murderer's modus operandi is constantly being conceived in his mind.

If the killer enters through the door, kills the deceased, and locks the door from the inside of the house with the deceased's fingerprints, the killer will not be able to escape from the 20th floor, where the doors and windows are closed.

And if the murderer went out of the door after killing the deceased, it doesn't matter if the blood on the soles of his shoes would leave blood stains on the carpet in the living room, and how did the murderer lock the door?

What if there was a murder mechanism in the room that the murderer had set up in advance... After all, the lock on the door of room 2001 was picked open... No, no, no... So how did the murderer take the murder weapon from the secret room, and how could he be sure that the deceased must have lived in this room that was set up with a mechanism...

When Li Xiaonan was about to light the second cigarette, Zhao Yinglu knocked on the office door.

"Come in."

"Lao Zhong said that when he just went to re-investigate the scene, he found some black particles in the blood piled up at the door of the crime scene, and he asked you to go over, saying that he called you but, no! Person! Pick up! After Zhao Yinglu shouted this sentence in a hurry, he turned off the mute and turned the volume to the maximum in the eyes of Li Xiaonan who looked down at the missed call on his mobile phone.

"If you don't answer the phone again in the future, don't use your mobile phone, and go to work with a brick in the future!"

Zhao Yinglu came in a hurry, and walked more vigorously, and even when Li Xiaoyan heard the last word, she couldn't see her figure anymore.

"Ugh..."

Li Xiaonan breathed a sigh of relief, picked up the phone, turned on the mute, and then walked out of the office.

“...”

9:00 a.m. sharp, "Writer's House", room 2001.

"Yesterday it was soaked in blood, and I thought it was dust or something." The old bell raised his finger slightly, and there were several small, pitch-black particles in the blood that had completely dried up on the fingertips.

Li Xiaonan put on his gloves, took the piece of blood from Lao Zhong's fingers, and gently rubbed his index finger and thumb, feeling a little diaphragm.

"Did you find it at the door?" Li Xiaonan asked.

Lao Zhong put the black particles into the physical evidence bag and took them back to study, and replied: "That's right, there are traces of the refrigerator in the kitchen being moved, I don't know if you noticed it before, the refrigerator is very high, very big, and it doesn't look cheap..."

"Do you want me to have one for the bureau too?" Li Xiaonan interrupted the old clock's chatter a little helplessly.

After Lao Zhong left, Li Xiaonan came to the inside of the door of the room at the scene of the crime, faced the door and closed the door, raised his head to look at the wall that was obviously higher than the normal room.

The walls are covered with neat wallpaper, black and white blocks, like the walls of the old farmhouse's own cottages, with bricks and slates accumulated.

"Boss, the brother downstairs said that the trash can outside the apartment seems to be on fire." The police officers guarding the scene outside the cordon shouted loudly to Li Xiaonan.

"Fire?" Li Xiaonan walked out of room 2001 quickly, hesitated for a few seconds, and walked into the elevator.

"Ding... The first floor arrived. ”

The moment the elevator opened, a squinting man hooked the corners of his mouth and passed by Li Xiaonan, and when Li Xiaonan reacted and turned around to hold the elevator door, the elevator door was already closed.

Li Xiaonan hurriedly pressed the button next to the elevator door, but to no avail, at this time the elevator had risen to the second floor.

He stood there with a gloomy face as he watched the elevator ascend to the floor.

20th floor.

"This is the scene of the crime, and it is forbidden to enter without permission." The guard outside the cordon stretched out his hand to stop the squinting man and said with some caution.

"Detectives of Class A and above have the right to investigate the crime scene on their own, Ah Si

。 The squinting man's voice rose slightly, and he took out a card identifying the detective and handed it to the officer.

Suspiciously, the officer pulled out a machine from his pocket, a bit like a poss machine, but it served a bit like an old-time punch card machine for identification.

Especially in such a world view where detectives are everywhere, basically every time they go out on a mission or scene, the police will bring one with them, which can save some detectives the trouble of having to go back and forth to the police station to ask for permission if they want to earn "fame" through a certain case.

After all, there are a lot of troubles like this, and the detectives at the A level and above are all trustworthy, at least except for Li Xiaonan, who thinks so.

"Drop, A-class detective. Welcome, Saravier, and thank you for your contribution in the quest for truth. ”

The automatic voice of the "punch card machine" made the police officer a little embarrassed, although he also thought that this sentence was really cool, but it was still unacceptable to come back every time he swiped the card.

"In order to avoid unintentional damage to other evidence that may be present at the scene, your inquest time is only 10 minutes." The officer leaned sideways to get out of the way and said as he untied the cordon, "Please forgive me, Mr. Detective." ”

"Thank you for your cooperation, Asi

。 Saraville shrugged her shoulders and entered room 2001, accompanied by another police officer.

“...”

Li Xiaonan was a little anxious and kept pressing the upward button of the elevator.

When he had a hunch that the man was going to the 20th floor by elevator, he made a phone call to confirm with Lao Zhong: "Did all the physical evidence in the trash can outside the apartment be packed and brought back in advance?" ”

He got an affirmative answer.

"If anyone comes out of the apartment before I come out, let them stay." Li Xiaonan instructed the police officer outside the apartment, and entered the elevator that seemed to be getting a little slow.

"Ding... The 20th floor arrived. ”

When Li Xiaonan stepped out of the elevator, he immediately asked, "Has anyone been here, just in these few minutes." ”

The police officer was stunned for a moment, and replied, "There is an A-class detective who came to search for evidence, is it the helper you are looking for, boss?" ”

"Show me the information." Li Xiaonan sighed slightly, even he, the police station detective, couldn't deprive those detectives of their rights in some aspects, after all, it was a long, long time ago, and the detectives fought for themselves.

Li Xiaonan re-entered the scene of the crime with some trepidation, and his eyes were no different from a few minutes ago, but he was still sure that the detective named "Saraville" must have an inseparable relationship with this case.

Detectives have the rights of detectives, so detectives also have the rights of detectives.

Within three days of the occurrence of the crime, although the detectives are not refused to come to the scene of the crime to investigate, the detective has the right to block the case information for three days, and until three days later, the detectives will be open to the detectives to collect evidence or conduct an inquest.

And in this case, Li Xiaonan has not released news to any detective, except for the personnel in the police station, only three suspects know the situation, and they are still locked up in the bureau.

After the investigation was fruitless, Li Xiaonan dialed a phone with some hesitation.

"Yo, what kind of wind blew Inspector Li here, is there any case that has been stumped! Why didn't you contact Qin, do you think I'm still easier to believe, Ananda~"

There was a flirtatious female voice on the other end of the phone, and Li Xiaonan couldn't help but think of the stupid appearance of her comparing her right hand to the shape of "eight" and holding it on her chin.

Suppressing the urge to hammer her, Li Xiaonan interrupted the chatter on the other end of the phone: "Detective Meiya, it's the detective's request for help, you give me a little restraint." ”

"Oh? So what does Inspector Lee want to ask me, a rookie detective, for help? Meiya's tone was still frivolous: "It won't be for me to help investigate Officer Zhao's personal interests, okay, Tamel told me that you two are not suitable..."

"Help me find out about a squint-eyed man in your detective world named Saraville." Li Xiaonan gritted her back molars, interrupting Meiya's unwarranted delusions again.

"I can't imagine that Tamel who looks like Jean is paralyzed like Jean would gossip like this." Li Xiaonan thought a little weakly.

Dealing with these detectives is really more difficult than solving cases, at least Li Xiaonan has always felt so.

The other end of the phone suddenly quieted, Li Xiaonan was faintly strange, and when he was about to ask a question, a cold male voice came from the other end of the phone: "It's me." How did you know the code name of Saraville, Ananda? ”

In the face of Tamel's question, Li Xiaonan frowned, although he didn't like these mavericks, even though they had special skills, but in fact they had a very vague sense of justice, but it was undeniable that Li Xiaonan did become good friends with some of them.

For example, Tamel, who is currently asking him questions, is a cold "tenor" image, and his thin, tall and cold appearance can really blend perfectly with the word "detective".

"He was here at the scene of the crime." Li Xiao replied succinctly.

"Is he still in the A rank?" Tamel asked again without a word.

Li Xiaonan was stunned for a moment, realizing that this Saraville seemed to be an old acquaintance with his friends, and replied: "That's right, and came to the scene of the crime that has not yet been made public by the police station without authorization, so his identity..."

"Blade of Betrayal and Damnation, Saraville." Tamel replied: "A genius detective who has abandoned the justice in his heart, and since that 'showdown of the century', if I remember correctly, this is his first appearance in the public eye in five years." ”

"I'll talk to you about it when I and Meiya rush back to Poland City, I hope you haven't solved the case in three days." Tamel's cold voice seemed to be mixed with a hint of teasing, "Be careful this time, Ananda." ”

Hanging up the phone, Li Xiaonan thought about Tamel's words while unconsciously walking towards the 2001 outdoors, and just as he was about to step out of the room door with one foot, there was a "zila" sound of a short circuit behind him.
