April 16, 2018, 22:00 p.m. sharp.

Li Xiaonan sat in a police car, and the road on both sides was accompanied by the sound of "whoop woo woo" sirens, and red and blue were speeding by.

Seeing the police car disappear from view, Li Xiaonan lowered his head in frustration - he also wanted to join the search operation tonight.

Because there is a new case, it means that the person behind the scenes has shot again, and "she" has taken action, which also indicates that there will be more clues - more clues mean that there may be flaws.

Beside Li Xiaonan, a young police detective looked nervously guarded, and the atmosphere in the car was depressing.

The glass window of the back seat reflected Li Xiaonan's frowning face, and at this time he silently recalled the calculation in his heart: "If the memory is correct, after the salted fish finished investigating the bedroom, combined with the remaining cigarettes in the cigarette box on the table, and the cigarette butts of the same brand in the ashtray, plus the one that was burned by himself, the number is exactly twenty." ”

"But where did you lose that extra cigarette butt..."

“...”

22:50 p.m., Dia City Police Station.

Li Xiaonan sat in the interrogation room for interrogation, and he told the young police detective opposite him what he had seen and heard in the last four days.

"According to the surveillance records on campus, it can be easily investigated that when I went to that boulevard at noon today, I didn't carry anything like a package, and my recent trip has not been out of the scope of monitoring, not to mention that there is a group of people who are suspected of following me, and they can also prove my trip..." ”

The voice fell, and without paying attention to Li Xiaonan's defense, the detective left the interrogation room with the notebook that recorded the confession.

"Alas..."Li Xiaonan looked at the door of the interrogation room that was closed, and sighed: "What's the point of 'she' doing this... I'm innocent..."

Thirty minutes later, with a "bang", the door of the interrogation room was pushed open with a bang, and the salted fish with a dull hair on end hurriedly walked in.

"Can I go?" Li Xiaonan raised his head and asked.

Salty fish did not answer, but walked behind Li Xiaonan and reached out to turn off the video recorder in the interrogation room.

As the flickering red dot went out, Salted Fish took out two cigarettes from his pocket and handed one to Li Xiaonan.

"I may have to quit smoking in the future..."Li Xiaonan said helplessly, but his body honestly put the cigarette in his mouth.

Salted fish looked at Li Xiaonan's "werewolf" behavior with disdain on his face, and said, "Not for the time being, at least until the end of tonight's search." ”

"If we find the owner of the video recorder, Wen Tingting, or catch the man who threw the body, maybe it can indirectly prove that you were framed."

"But if there is no trace of them, then through the existing clues, I can only suspect that you are secretly cooperating with the mastermind to divide the body."

"In other words, maybe you're the only one who can save you right now... Think about where you've smoked, DNA tests can last up to fifteen days, and if you can't remember where the cigarette butts came from, the worst could be that you'll be detained until the end of the tryouts. ”

Li Xiaonan took a deep breath of cigarette, rolled his eyes and looked at the ceiling, and muttered: "So my bedroom has been searched, right, counting the one in the iron bucket on the balcony, it is exactly twenty..."

"It is true that there is half a burned cigarette butt in the iron bucket, but due to the severe contamination of the sample, there is no way to compare it by identification means that it belongs to you... Although the cigarettes are of the same brand...", Salted Fish replied, and then changed his words: "But between the testimony of others, it can be inferred that the cigarette butt found with the human bones must not belong to the last four days. ”

"Those who stalked me?" Li Xiaonan was very keen, and he asked again, "Who are they?" ”

"Detective," Salted Fish replied crisply, "Someone like you who participated in the tryout learned that you and Feng Burial had obtained the manuscript kept by the three Death Detectives, so they wanted to steal it in this way." ”

"Huh?" Li Xiaonan was a little confused: "Speaking of the secrecy work of your police station..."

Xianyu immediately interrupted Li Xiaonan's dangerous speech: "First, even third-rate detectives have their own 'connections' or channels, and I am not interested in investigating these; ”

"As for your infighting or involution, it has nothing to do with the Dia City Police Department."

"Alright, alright... I don't mean anything else..."Li Xiaonan was a little soft, and asked Xiang Xianyu again: "Then why didn't they follow the wind for burial, obviously he took the manuscript." ”

Salted fish pursed his lips and replied as if he hated that iron could not be made of steel: "Maybe it's because the wind is buried and there are two of them, and it is difficult to track and easy to expose." On the contrary, you rely on public transportation to get around, which is easy to predict and easy to follow. ”

Li Xiao nodded and responded, "I understand, I understand... So what you mean by 'other people's evidence' is that they sneaked in when I left the dormitory, and may have even stayed in it, so it is easy to conclude that the cigarette butt was lost four days ago through the comparison of confessions, right? ”

Hearing Li Xiaonan's analysis, Xianyu raised his eyebrows: "This bit of cleverness can't help you leave here, let's think about the location where you smoked, I'll send someone over at any time." ”

With the sound of footsteps, Salted Fish took the two cigarette butts away and left the interrogation room.

Li Xiaonan lay on the metal table, thinking with his eyes closed. Of course, he understands Salted Fish's concerns and his current situation - if the victim's identity is successfully matched, but he has the slightest social connection with him, then he will face endless interrogation and detention.

“...”

April 17, 2018, 7:00 a.m., Dia City Police Station.

"So at present, there is no direct evidence or a complete logical chain to prove that my client is related to this case, he was framed, maybe it was just that the murderer randomly picked up a cigarette butt and put it in it to confuse the public..."

After learning what happened, Feng Beifu and White Candle Aoi came to the police station early in the morning with their lawyers.

At this time, the lawyer was sitting opposite the salted fish, gushing his opinion.

Taking advantage of the gap between the lawyer bowing his head and drinking water, Salted Fish said: "It is impossible to let him go without a definite conclusion." You can complain about me at any time, but I can't joke about the murder. ”

Then he looked beyond the lawyer who was thinking about his words, and looked at the two Feng Fu brothers who were leaning on the door frame: "I feel the same as you, but if emotion can overcome logic, then whether it is a police detective or a detective, our work will lose its original meaning." ”

"Li Xiaonan's personal belongings are next door, and the police station has checked that there are no suspicious contacts or messages, so you can take them."

Just as the lawyer was about to fight for something, Feng Beifu walked over, patted him on the shoulder, and signaled that he could leave.

Then Feng Beifu asked Xiang Xianyu: "Can I see him?" ”

“...”

Three hours later, the "ploughing" search, which lasted all night, ended just as everyone expected — no trace of the suspect was found, except for Li Xiaonan, who had been detained, and two abandoned tires.

The sad-faced salted fish agreed to the request to meet under the repeated requests of the wind to be buried, but only on the condition that he should accompany him.

In the interrogation room, Feng Beifu sat in the seat opposite Li Xiaonan and asked, "Still haven't you remembered anything?" ”

Li Xiaonan raised his head, looked at Feng Beifu through his bloodshot eyes, and shook his head: "It seems that the search operation failed..."

Feng Beifu bowed slightly, and continued: "That cigarette butt was discarded in the same plastic bag as the human bone, but the strange thing is that it has not been contaminated, and you can easily extract your DNA from it, which means that the cigarette butt was not thrown on the ground by you at will, and the people behind it have carefully preserved it. ”

"I know..."Li Xiaonan's voice was very soft: "But I really don't have an impression... Where people will take advantage of the loopholes..."

Suddenly, Li Xiaonan seemed to think of something, and just as he was about to speak, a text message interrupted him.

"Who will send me a message at this time..."Feng Beifu motioned for Li Xiaonan to stop, then lowered his head and took out his phone from his pocket, and after unlocking it, he found that it was blank...

"Could it be..."The voice of the salted fish came from the side of the wind to be buried: "Ananda's mobile phone?" ”

Feng Beifu's response was equally rapid, and at the same time as the salted fish spoke, he had already reached out and took out Li Xiaonan's mobile phone from another pocket, and brought it to Li Xiaonan, in the affirmative gaze of the salted fish, Li Xiaonan stretched out his finger to unlock - "Dear Mr. Li, thank you for staying in this hotel, your room will check out on time at 12:00 today, if there is no plan to renew your stay, please bring your personal belongings to check out at the front desk on the first floor and return the room card, if you are satisfied with this service, please rate me at the following website." ...”

"Didn't you check out three days ago?" The voice of the salted fish is urgent.

At the same time, Feng Beifu closed the page on his mobile phone and flipped down to the text message from three days ago, which contained an identical message...

"Yes," Li Xiao replied with a smile.

A few seconds later, as if reconnecting his brain, Li Xiaonan said again: "That's what I just wanted to say, I only honestly put cigarette butts into the ashtray in bars and hotels..."

"And my room was never cleaned by the staff during my stay."

"Someone has taken up your room." Feng Waiter summed it up succinctly, then straightened up and glanced at the wall clock on the wall of the interrogation room—the time was 10:39.

"I need to be at the hotel room you used to rent by 12:00." Feng was buried and only left a back for Li Xiaonan, and his voice came from outside the door: "I hope that room is still uncleaned." ”
