Aria on the G string.

The most rational symphony in the world.

Shi Zuo is the martyr of reason. He firmly believed that the essence that distinguishes human beings from animals lies in reason.

When he is in an impetuous mood, this piece can help calm him down.

During lunch break, the campus radio plays the tune.

This is the reason why he rarely likes Hikatsu.

He unlocked the door on the top floor and sat on the roof of the school, next to an unopened boxed lunch.

This is his second secret base.

For him, the student cards distributed by the school are the master key to the places where every student is not allowed to enter. This little trick was originally the work of Mr. Demon, but he has been used for a long time.

No one will disturb his peaceful lunch break anymore - especially the annoying Willow Smoke Vision.

He could wander in the river of reason and be alone until two o'clock in the afternoon.

Listening to the calm melody, Shi Zuo gradually felt a little tired.

After a while, he heard footsteps.

When I opened my eyes, I sighed silently in my heart.

Smiling willow smoke.

and Fu Yinger.

……

……

……

"The first time I realized the strangeness of this case was the forensic documents you sent me."

Zhu Ansheng took a puff of cigarette and collapsed on the sofa.

Xia Liang frowned and asked:

"Forensic documents?"

He remembered that Zhu Ansheng had indeed printed out the document and studied it, and had made a lot of notes on it.

"Fu Sizhe's corpse identification characteristics are that the body surface shows cherry red spots, kidney failure, and the preliminary judgment is ...... The time of death was more than twelve hours. ”

Zhu Ansheng smiled:

"It's all in line with the characteristics of frostbite. The medical examiner could not determine whether the fatal wound was a blow to the head, and it is not ruled out that he had stopped breathing before the blow was received, as he may have froze to death. ”

"What's wrong with that?"

"Have you ever learned about forensic science?" Zhu Ansheng turned his head to look at Xia Liang, who shook his head:

"That's a completely different field from my major."

"Sometimes, if you want to investigate a case, you have to be like a panacea, you have to know a little bit about all the mess." Zhu Ansheng spit out a cigarette and said lightly:

"There is one of the more interesting topics in forensics. When determining the cause of death of the deceased, there are two ways of death that are more likely to be confused......"

He narrowed his eyes slightly:

"Freezing to death, and carbon monoxide poisoning."

Xia Liang was stunned.

Zhu Ansheng continued:

"The characteristics of the corpses presented by these two types of death are very similar, as I just said, cherry red spots, kidney failure, are the characteristics of people who freeze to death, and they are also the characteristics of people with carbon monoxide poisoning."

"Do you want to say that Fu Sizhe actually died of carbon monoxide poisoning? How is that possible? ”

Xia Liang's eyes widened:

"Normally, the concentration of carbon monoxide in the blood of a deceased person who smokes gas or burns charcoal will be frighteningly high, and there is no reason why forensic doctors can't detect it, right?"

Zhu Ansheng lifted Erlang's legs and said:

"Unless the deceased has been dead for a long time and the concentration of carbon monoxide in the blood has dropped to normal levels."

Xia Liang shook his head and said in wonder:

"That's ridiculous...... Fu Sizhe obviously found it in the cold storage, no matter what, it is more reliable to freeze to death, right? ”

Zhu Ansheng looked at him deeply and exhaled.

"This is the real cleverness of the 'murderer' to choose the location of the crime in the cold storage. is not only to pretend to be the deceased and arrange a double secret room, but most importantly, to make it impossible for forensic doctors to determine the real cause of Fu Sizhe's death and create a 'blind spot'. ”

Xia Liang asked confusedly:

"Blind spots...... What is it? ”

Zhu Ansheng did not answer, but asked rhetorically:

"Xia Liang, why do you think I have been emphasizing that the murderer is an absolute genius before?"

Xia Liang didn't speak, shook his head.

Zhu Ansheng smiled and said:

"The average person who wants to make something complex can spend a lot of time and effort creating details that make the whole event confusing. But true geniuses don't need to do this - they just start from angles that ordinary people can't even think of, and use simple means to complicate the whole thing in one fell swoop. ”

Xia Liang frowned slightly, and without waiting for him to ask again, Zhu Ansheng said:

"The most ingenious thing about this case is that the murderer used time trickery to turn 'suicide' into 'homicide'."

Xia Liang sat up straight and suddenly widened his eyes:

"Fu Sizhe committed suicide?"

Zhu Ansheng nodded.

"On Saturday morning, I borrowed your police ID and went to Fang Qing's house."

"What did you find?"

"There are a lot of doubts."

Zhu Ansheng thought for a while and continued.

"When I realized that Fu Sizhe might have committed suicide, I began to wonder about the real time of his death. Because the time of death of the body was affected by the temperature and cannot be determined, the possibility that he died on Saturday morning cannot be ruled out. ”

"However, in this way, another problem arises: if Fu Sizhe died on Saturday morning, there are still twelve hours before ten o'clock in the evening and he is brought into cold storage, which is enough time for the body to stiffen and change, and the medical examiner has not identified this."

This means ...... It is likely that the deceased was kept in a cold environment before being put in cold storage. ”

Xia Liang muttered:

"That being said, there are only a few cold stores near Huangsha, so you can't keep him in the refrigerator, right?"

Zhu Ansheng glanced at him:

"No need for a fridge. Just a large number of ice packs are sufficient...... I investigated the seafood market, and on Saturday afternoon someone borrowed a cart from the owner and bought 20 bags of ice. According to the description of the appearance, they all match the age and characteristics of Shi Zuocai. ”

"After I entered Fang Qing's house, I went to the toilet on an excuse and found that her house had a bathtub. There is no dust on it, so it must have been used recently. But when I asked about it, Fang Qing's answer was that no one had used the bathtub during this time. ”

Xia Liang's eyes widened.

"In other words, after Fu Sizhe's death, the body was placed in a bathtub filled with ice packs, delaying the time for the body to decompose and stiffen......" Zhu Ansheng nodded and continued:

"In addition to that, I noticed one thing...... Fang Qing said that their family has not lit a fire to cook in recent days. ”

Xia Liang nodded hurriedly.

"I also noticed this, Zhao Gang said that he visited several times and found that Fang Qing was ordering takeout and eating very lightly, we just thought it was because she was not in the mood to cook."

Zhu Ansheng smiled noncommittally:

"It's understandable to think so. But if you use a more conspiracy theory idea - the reason why she didn't make a fire was because there was a psychological shadow to deal with Sizhe's charcoal suicide, it might make sense. ”

Xia Liang quickly frowned, noticing the details in Zhu Ansheng's words:

"How can you be sure that Fu Sizhe committed suicide by burning charcoal? Couldn't it be gas poisoning? ”

Zhu Ansheng shook his head.

"Because Fu Sizhe committed suicide in the study."

Xia Liang was shocked and hurriedly asked:

"How is that possible? My colleague also looked into the room and didn't find anything out of the ordinary...... Because Fang Qing had already done a big cleaning to get rid of ......"

"You have a different mentality than me when you investigate, so you will naturally subjectively omit some details." Zhu Ansheng explained:

"When you first went to investigate Fang Qing's house, most of you probably didn't believe that Fang Qing would kill her husband - in fact, it was. So you just think of it as a businessman, and you don't care about the inconspicuous places. ”

"And I'...... It was with the idea that Fu Sizhe was very likely to commit suicide when he walked into Fang Qing's house. ”

Xia Liang was silent for a while, and then asked:

"So, what exactly did you find?"

Zhu Ansheng smiled:

"The floor in the study was very clean. However, the floor at the edge of the wall has a color difference, and the color of the tiles is relatively darker, and the part of these color differences is exactly a rectangle. ”

"So there should have been a rug in the study?"

"It's tatami mats." I wish Ansheng to correct.

Xia Liang was stunned: "How do you know?" ”

"Because I found it." Zhu Ansheng laughed:

"There is a garbage recycling station next to the Fu'an community, and it usually takes two weeks to clean it. The area of tatami mats is not small, and I was lucky enough to find one without much effort. ”

"How can you be sure that it is Fang Qing's family? Maybe someone else discarded it. Xia Liang retorted.

"Because I found marks on that tatami mat that had been burned through coal." Zhu Ansheng knocked his pipe and said with a smile:

"The lowest temperature in Guangzhou during this period is only seventeen or eighteen degrees, and no one will burn charcoal at home for heating, right?"

Xia Liang was silent for a while.

"Besides, I've found the most crucial evidence."

Zhu Ansheng stretched out his hand and rubbed his fingers.

"I touched the door frame in the study. There are still traces of adhesive tape that have not been cleaned up, and the hands are sticky. ”

Xia Liang sighed.

"I think it makes sense for you to say that...... After all, Fu Sizhe was not stunned by chloroform, but took a lot of sleeping pills. If this is a preparation for suicide by burning charcoal, it all makes sense......"

"When you see through this little trick, everything else will be understood."

Zhu Ansheng sighed deeply and said:

After Fu Sizhe cut himself off, his body was stored in the bathtub and waited for the evening to come. When the owner of the aquatic shop was stunned, he took Fu Sizhe's body to the cold storage, and then directed and acted in a double secret room. This is the game he set. ”

The reason why he did not destroy Fu Sizhe's teeth and left a dental record was so that the police could identify the deceased more quickly. He didn't have much time because he had to get the police to announce Fu Sizhe's death as soon as possible. In this way, Fu Sizhe's three insurance benefits can be received as soon as possible. ”

"There is no way to crack this game...... Because when you play this game, you're already losing. ”

"When you receive a report and rush to the cold storage to find the deceased, due to the existence of the double secret room, you will immediately characterize the case as a homicide, and thus start investigating the identity of the murderer."

"You have exhausted all means to interrogate the two suspects in the secret room and investigate Fu Sizhe's interpersonal relationships, financial situation, and family ...... Just to find out who killed him. At first, you think that the suspects are security guards Liu Zhongwei and Zhang Jianhong, but later you will realize that they are just innocent people who have been dragged to take the blame; After that, you will start investigating Fang Qing and her alibi...... I thought that as long as this alibi was falsified, I could get more clues......"

The alibi she provided looked shaky and ready to be shattered at any moment. But that's not the case. ”

They were wearing inconspicuous clothes, and Fu Yinger was wearing a mask. Only went to a few places with great foot traffic that surveillance footage could not capture, leaving ambiguous transaction records and movie bills. It's a huge smoke bomb, and no matter how much effort you put into it, you won't find any clues in it. Because on Saturday afternoon, Fang Qing and Fu Yinger did go to Tianhe City Plaza. ”

Zhu Ansheng turned his head and glanced at Xia Liang deeply.

"Because Fu Sizhe died on Saturday morning, the alibi on Saturday afternoon is not relevant at all."

Xia Liang pursed his lips and asked again:

"How are you sure he died on Saturday morning?"

"Because of the screams." Zhu Ansheng shrugged his shoulders, and Xia Liang looked at him puzzled.

He explained with a smile:

"I went to Fang Qing's neighbor Chen Dong's house to find out if I heard any strange sounds at the door all day on Saturday. He told me that at noon, he heard Fang Qing's screams. ”

Xia Liang opened his mouth slightly. He remembered that he had heard Zhao Gang say this message on the phone, but because Zhao Gang said that it was because there were cockroaches in Fang Qing's house, and the time was in the morning, he didn't pay much attention to it. He muttered:

"So...... Fang Qing should have found out that Fu Sizhe had committed suicide at noon...... Then, Shi Zuo helped her cover up the incident and turned suicide into homicide? ”

"That's how it should be."

Zhu Ansheng sat up, his mind flashed the scene of Zuo Cai making a pistol pose to himself, and shook his head with a wry smile:

"From the very beginning, he had the whole plan in place...... It also includes the part of the condemnation at the end. In retrospect, the plan was indeed interlocking, and it was the perfect art of crime. It's just that there is no murderer in this case from beginning to end. We used to think that Zhang Jianhong and Liu Zhongwei were innocent scapegoats, but later we found out that the real scapegoat was actually Shi Zuocai himself. ”

And all of this is based on that little trick of time at the beginning. When a case becomes more and more perfect for murder and there are more and more suspects, it is difficult for people to break through the habitual thinking and find that this is not actually a murder case. ”

"There's a lot of amazing calculations going into the whole layout. From the moment he found Fu Sizhe's body, he completely removed Fang Qing's mother and daughter from this case, the reason why you can't ask any useful clues from Fang Qing's mouth at all is because Fang Qing doesn't know what Shi Zuocai plans to do and what he has done. She should have just taken her daughter to Tianhe on Saturday afternoon, left an alibi, and then did a big cleaning the next day. ”

Xia Liang suddenly remembered the shock and horror on Fang Qing's face when she saw Fu Sizhe's body destroyed. It was precisely because of this expression that he felt from the bottom of his heart that Fang Qing had nothing to do with this matter. Thinking of this, he couldn't help but sigh in his heart.

"I seem to have been calculated from beginning to end."

Zhu Ansheng looked at him deeply and took a puff of cigarette. Said slowly:

"That's true...... Including the part where he turned himself in at the end. ”

Xia Liang was stunned: "What does this mean?" ”

Zhu Ansheng sighed and said:

"I had contact with him the day before he turned himself in. When I looked back afterwards, I realized that I was also put on a role by him. He deliberately misreported your license plate number, and I didn't notice it - just by this small mistake, he concluded that I should have been with the police. ”

Zhu Ansheng turned his head:

"Liang, you also went to school that Sunday, right?"

Xia Liang was silent and nodded.

Zhu Ansheng shook his head and said with a wry smile:

"I'm just a private investigator, and none of my actions can be used as direct evidence by the police. But you're different...... Your investigation in the school has become the strongest evidence to convict him. ”

Xia Liang's eyes widened, and he was completely speechless.

After a moment of silence, Xia Liang muttered:

"Brother-in-law, these things...... You already investigated before he turned himself in, right? Why didn't you tell Team Xing...... Tell us about it? ”

"What's the use of telling you?"

Zhu Ansheng asked coldly. Xia Liang looked at him in surprise.

He just shook his head and sighed.

"I've already said that from the moment we get in, we're already losers."

"Even if you tell Lao Xing the truth now and reverse the whole case, what will be the result? You should know better than me about the family situation of the mother and daughter, and they are stretched. Without that insurance money, they can't live anymore, you should also know the ability of that Shi Zuocai, the police force knows the truth will only help him clear his suspicion and resume the life of ordinary people, but now...... At the very least, it can put him in a focused observation environment to prevent him from doing even more terrible things. ”

Xia Liang pursed his lips tightly, his mood was complicated. He never imagined that the whole case would develop into what it is now - there are no murderers, no "bad guys", and behind the brutally destroyed corpses, there is a desire to save people...... Everything seems ridiculous and shocking.

He clenched his fist and slowly released it. There was a little more confusion in his eyes.

"All this...... Is it really just to cheat the insurance money? ”

Zhu Ansheng picked up a pinch of tobacco, filled it into his pipe, lit it with a match, took a deep sip, raised his head and sighed, the smoke swirling in the room.

"If that's the case, the story wouldn't be worthy of being called cruel, nor worthy of being affectionate."

Xia Liang frowned: "What does this mean?" ”

Zhu Ansheng turned his head, looked at him deeply and said word by word:

"From the moment we entered the game, we were already losers."

"We are, and so is Shi Zuocai."

……

"Aria on the G String" is still lingering around the campus, and it has entered the second half.

Shi Zuocai frowned slightly.

Ying'er said that she had thought about some things for a long time and decided to tell us both at the same time, you have to listen carefully."

Liu Yanshi smiled.

Shi Zuocai glanced at her, then moved his gaze to look at Fu Ying'er.

There was still a lingering sadness on her face, but the shadow in the depths of her eyebrows seemed to have been swept away. It's like a blue sky that rains past the sky, and a heart-warming crimson brushes.

She pursed her lips, wrung her fingers slightly, and said:

"Thank you...... Thank you also Xiaoyan. ”

She paused, and continued:

"In fact...... I haven't been very happy for a while, although it's also because of my family, but ...... Actually, it's not entirely because of family affairs......"

She raised her eyes to look at the two beside her, took a quiet breath, and a blush flew across her face.

"Actually......"

"I have a half-sister who lives in New York...... I only found out a few years ago......"

"We've always had a good relationship, but she seems to have had a lot of trouble some time ago...... I don't want to tell me...... However, it seems to have been resolved recently, and I'm really happy......"

Liu Yanshi's smile froze on his face.

"Aria on the G String" comes to an abrupt end after the last note.

Shi Zuocai opened his mouth, as if he had been struck by thunder.
