The small restaurant was directly opposite the school gate, and Mo Ziqi followed Mu Sen as he walked inside, and asked, "How do you know what you can ask when you come here?" ”

Mu Sen seemed to find a seat casually, but the angle of the seat was facing the entrance of the school. Pen & Fun & Pavilion www.biquge.info everyone who walks out of the school can sit here and see it at a glance.

"Every school has a little meeting point nearby, maybe because the food is good, maybe it's cheap, or maybe it's because the owner is a nice person," says Mussen. Anyway, there will always be a place where you can mingle with the students. ”

At this time, the boss brought the menu. Mo Zitong just glanced at the boss lightly, and saw that this little boss was very shrewd, and he was definitely a businessman who could do business.

I saw him look at Mu Sen and them with a kind face, and then asked with a smile, "What do you want to eat?" Or is it ...... Just want to sit around here? ”

"Oh? Nothing, just sit here? One sentence aroused Moossen's curiosity.

The boss touched his head and smiled: "Of course I don't want this to be the case, but the people who come to me are parents in addition to students." Probably because of the good location, they always want to see what their children are like when they come out of school on weekdays. In fact, I don't really approve of this kind of quiet supervision. I don't think you two are like teachers, you are not like parents, and you can't be students. They didn't look like they were going to come to my little place to eat. When you came in, you didn't look at the environment or the signature dishes, and you just chose that seat, so I thought ......"

Mu Sen nodded slowly: "In other words...... It's a great spot for a peep. ”

The little boss waved his hand again and again: "Ouch, don't say that." Hehe, today's parents hope that their sons will become dragons and their daughters will become phoenixes, and everyone wants their children to be the most promising, so sometimes the practice may be a little excessive. However, this school is a well-known brand in the city, and the children are very well-behaved and don't do anything out of the ordinary. ”

Mu Sen looked at the boss with a smile on his face, and then ordered two dishes, and the boss happily went to prepare the meal.

"It's very talkative, it's very chatty, it seems that you can gain something this time." Mo Zitong sat in this small and simple position unnaturally, and said to Mu Sen casually.

After a while, the meal came up. The dishes are simple but clean. This at least proves that this little boss does not belong to the kind of people who are black-hearted traders.

While praising the delicious food, Mu Sen asked the little boss as if chatting, "Boss, you must be familiar with the students of this school, right?" ”

"It's okay, I've been working for a long time, and I know most of them. Even if some of them can't be named, you can tell whom's right by looking at their faces. The little boss said with a smile.

Mu Sen nodded with satisfaction and said, "Then look, are you familiar with this girl?" As he spoke, he took out a photo from his pocket, and the person in the photo was Lin Wei.

The little boss picked up the photo, only glanced at it and said, "This girl is famous, I heard that the grades in this school are among the best!" People are beautiful and beautiful, who can not know! If I'm not mistaken...... Her name is Xiaowei, right? ”

"That's right. Do you know who she usually has a better relationship with? Mussen continued.

"Ouch, that's hard to say. You don't know, this girl's popularity is very good. She has good grades and is willing to help her classmates who are lagging behind. People are beautiful, but they are not proud. Anyone to talk to is very polite and polite. She hasn't eaten much at my place, probably because the family conditions are good, and the family is strictly controlled, so she is not allowed to eat outside! The little boss said that Lin Wei's expression was very serious, and he didn't seem to know what happened to Lin Wei's family. However, good things don't go out, and bad things spread thousands of miles. I believe that the Lin family's affairs spread throughout the school, and it was a matter of half a day.

Mu Sen glanced at Mo Zidi, the situation that this little boss said was no different from what Yang Chen said. It seems that this Lin Wei is indeed a very good girl, who can leave such a good reputation and such an excellent impression.

Mu Sen asked again: "Do you know that Lin Wei's best female classmate?" ”

The little boss thought for a while and said, "What's that Lan's name, right?" ”

"Li Lan." Moossen replied.

"yes, yes, I think it's weird to talk about this girl. Compared to Xiaowei, in every way, it is like a contrast between a swan and an ugly duckling. She has a bad family and average appearance, probably because of the influence of her family environment, her academic performance is not very good. The students who came to me sometimes talked about this child, and they all said that she was climbing high branches and pestering Lin Wei every day. But in fact, I think it may not be the case, Lin Wei's girl has a good heart and is always willing to help her, and it is normal for the two of them to become good friends back and forth! ”

Mu Sen nodded, ate a few more bites of food, and then asked the boss to settle the bill.

After leaving the hotel, Mu Sen called Captain Wu.

"Team Wu, help me check the address of Lin Wei's classmate Li Lan. Since they are good friends, she may know more about Lin Wei. Ah, at the same time, you also continue to investigate Lin Wei's parents and grandparents to see if there are any enemies. ”

After Mu Sen finished speaking, he listened to Captain Wu on the other end of the phone and said, "Okay, the address will be sent to you in a moment." The results of the trace inspection here have come out, the fire point is Lin Wei's bedroom, in Lin Wei's small laboratory, and in the fireplace of the Lin family, some clothing fibers have been found. ”

"Lab?" Mussen felt a little strange.

Captain Wu replied: "Yes, it is a home with good conditions now, and a separate room for my children is prepared, which can do some small experiments, and it is also a study." ”

"The chemicals in the fire came from that little lab?"

"It should be, although it is not much, but it has an impact on fire fighting."

"So these things weren't brought in by the murderer, they were originally owned by the Lin family?" Mussen became more and more confused.

"Let's just put it that way." Captain Wu's answer was a little vague, and it was obvious that he couldn't be sure either.

"What kind of fire did the murderer light with?"

"Books. All the books in Lin Wei's room became fire-fueling objects, plus there were chemicals. I'll just tell you this, the scene was chaotic, and it didn't look like a professional murderer or a veteran at all. There was even a second and third fire point in the room, judging by my experience as a criminal police officer for so many years, the murderer must have been very flustered at that time! Captain Wu said very seriously, and he also imitated Mu Sen's criminal psychology line.

"Got it, you can send me the address of that Li Lan." After saying that, Mu Sen hung up the phone.

"Zidi, did you find any anesthetic drugs during your autopsy? How can a big family be inactive about the fire? Mussen asked, thoughtful.

Mo Zidi was slightly stunned, and then replied: "I have also considered this problem, but most anesthetics are volatile. You know that the fire has burned a lot of the evidence stored in the corpse, and unless the murderer used a very large dose, it is not easy for us to detect the charred corpse. What's more, there are chemicals present in the fire itself. ”

"So, let's go back together, and you check it again to see if they have chlorine/form or ether or anything like that." Mu Sen said with some eagerness.

Mo Zitong was a little helpless: "Mu Sen, you don't need me to teach you common sense in chemistry, right?" The corpse has been charred or even ashed, and you asked me to check those things that volatilize quickly when exposed to fire, it's too embarrassing, right? What's more, there will still be people who are stupid enough to follow the bloody plot in the TV series, and cover it with ether/ether, and people will faint? You are not ignorant, you should know that those are lies. Although ethyl/ether is best known for its narcotic properties, its effect is too weak. If you really want to stun an adult, you need to forcibly restrain him from inhaling ether/ether for at least a few minutes. Do you think this is realistic? Not to mention chlorine/form, which was often used by the German army during World War II, but now, it is already being replaced by ether in its own right. ”

"I know, but these are flammable and explosive chemicals, and they have an anesthetic effect after volatilization. As long as there is more than 2% ether/ether in the air, it can cause an explosion. In this way, both the anesthesia and the strange fire can be explained. Perhaps, the Lin family was unknowingly poisoned, and then because of the conflict between a fire in a bedroom and flammable chemicals in the air, it led to the final result. Mussen tried to analyze.

After hearing this, Mo Zitong asked with some doubts: "What about the murderer?" How did he get in? If he didn't know in advance that the Lin family had a small laboratory, then how could he use ether/ether? And how can he guarantee that he will not be poisoned? ”

"Unless...... Mu Sen stopped talking, his expression a little excited and a little annoyed, as if he was very close to the truth, but there was still a little bit of something missing.

Mo Ziqi couldn't help but ask: "Unless what?" ”

But Mu Sen didn't answer, he picked up his mobile phone and glanced at the message and said, "Let's go, let's go to that Li Lan's house first." ”

There was no way, Mo Ziqi had no choice but to accompany Mu Sen to the address given by Captain Wu first, that is, Li Lan's home.

After arriving here, Mu Sen and Mo Ziqi really realized the words of the little boss of the hotel. What is the difference between a swan and an ugly duckling. It's hard to believe that this child named Li Lan will not feel inferior when he is with Lin Wei, and he can even become friends.

Walking into the narrow alley, you can see the garbage and waste piled up on the muddy roadside, and all kinds of clothes drying on the high and low places...... It must be said that this is simply different from Lin Wei's family environment.

Mu Sen's heart faintly began to have some feelings, he felt that he seemed to have grasped the key to the arson case, as for the truth, he still needed to personally verify one thing.
