Judging from Meng Mei's reaction, Xiao Wei had already judged that she must know about Lei Peng's notebook.

Xiao Wei pushed the box of tissues on the table to Meng Mei, Meng Mei took out one of them, hurriedly wiped her tears and whispered, "Thank you!"

Xiao Wei saw that she had stopped sobbing and her emotions calmed down, so he continued: "Since you already know the existence of a notebook, do you know the contents inside?"

Meng Mei lowered her head and nodded.

"Then do you still firmly believe that Lei Peng only loves you alone?"

Meng Mei lowered her head and remained silent.

After a while, Meng Mei raised her head, opened her eyes wide and said, "Even so, I still love him, and I can't live without him in my world." My infatuation with him may be incomprehensible to you, and can be described as crazy. ”

"You love him so much, but does he love you?"

Meng Mei was silent, and then Rong said in a somewhat strange tone: "He must love me, because I love him, I can promise him to do anything he wants me to do, including what I think is the most precious, I can give him." ”

Xiao Wei looked at Meng Mei in front of him helplessly, and then turned his head to look at Long Mei beside him.

The two exchanged glances, and both had a kind of realistic helplessness and regrettable sadness.

Long Mei comforted: "Meng Mei, I can understand how much you love Lei Peng. But you must know that love is mutual, not one-sided. If it's just blindly obeying or blindly taking, it's not normal, and it only means that there is a problem between you. Do you understand?"

Meng Mei nodded and said slowly: "Actually, now that I know, it's too late, I feel hopeless." ”

Meng Mei picked up a tissue and wiped her eyes vigorously, and said: "Maybe it's a good ending for me now, at least Lei Peng won't fall in love with anyone else in the future, and he can be with me forever." I'm sorry, I'm feeling very uncomfortable right now, is there anything else you want to ask? If not, I'd like to go first. ”

Xiao Wei looked at Long Mei, looked at Meng Mei, and said: "Okay, you go back to rest first, and then think about it, some things are not what you imagined, if you don't think about it, it doesn't mean that it didn't happen." ”

Meng Mei looked at Xiao Wei and didn't speak for a full minute, then nodded and said, "Thank you!"

Then he picked up his satchel and turned to leave the private room.

Xiao Wei watched Meng Mei leave, and then said to Long Mei: "I'll follow Meng Mei first, you go and call Xiaojin of the security department, and ask him to rush to the door of the girls' dormitory and wait for me." ”

After speaking, Xiao Wei hurriedly followed Meng Mei.

Long Mei didn't dare to slack off, and after making the call, she also hurried to the girls' dormitory.

Xiao Jin came over, and he told Xiao Wei to hurry back to the office building, because Lin Feng was waiting for him.

When Xiao Wei hurriedly rushed to the school's office building to see Lin Feng and Song Qiankun, he knew what was going on.

It turned out that in the morning, Song Qiankun and Cao Fang Hospital had made significant progress in their investigation.

Song Qiankun and his team visited all the big hospitals, small hospitals and outpatient clinics in and around the school, and finally found clues in a small private hospital.

To be precise, three days before the crime, someone had bought fifty sleeping pills.

Since sleeping pills are restricted drugs, they are not sold in small hospitals, and the quantity of them purchased at one time is limited. The doctor at the time also asked the girl who bought the medicine.

The girl said that she was a student of Dream Worker, and because of the pressure of studying, she often had insomnia and couldn't sleep, so she came to buy medicine. However, the school's hospital management restrictions are very strict, and it is really troublesome to prescribe up to two tablets at a time, so I want to buy more and use it slowly.

The doctor at the private hospital looked at the girl very haggard at the time, not like a lie, and showed her his student ID card for her dream job, so he made an exception and prescribed her fifty sleeping pills (that is, one bottle), and the price was twice as high as usual.

Song Qiankun and the others found the doctor on duty, although he couldn't recall the name on the girl's student ID, but he had the impression that the girl was very beautiful, and it was not ordinary beauty, but a very outstanding kind.

Song Qiankun immediately thought of Meng Mei, and after identifying Meng Mei's photo, the doctor on duty confirmed that the girl who bought sleeping pills was Meng Mei.

Lin Feng analyzed: "Now it is basically certain that the person who bought sleeping pills is Meng Mei, so the person who put sleeping pills in Lei Peng's cup should also be Meng Mei." Then Lei Peng's gas poisoning is not a simple accident, but a man-made murder. ”

Song Qiankun replied: "Yes, according to the existing clues, it is true that this Meng Mei is suspected of committing a major crime. However, I remind everyone to pay attention to one point, that is, when Lei Peng died, his dormitory door was inserted from the inside, which means that there was only the deceased Lei Peng in the dormitory, so how did the murderer escape the scene and plug the door from the inside after committing the crime?"

This is indeed a problem, in fact, this issue has been discussed before, but the cause of Lei Peng's death could not be determined at that time, so it was only a possibility, and now this possibility has become a reality.

Lin Feng was also smoking a cigarette and pondering, obviously he didn't come up with a reasonable explanation.

At this time, Xiao Wei felt that he needed to remind everyone, so he said: "Brother Lin, Brother Song and Cao Fang, let me talk about my thoughts first. I haven't figured out what this is going on, but I'd like to share my thoughts on how I'm thinking about it. Let's hear if it makes sense. ”

Lin Feng motioned for Xiao Wei to continue.

"I've seen Hitchcock's films and Ellery Quinn's more classic novels, especially plots like the murder in the locked room. One thing they all have in common is that they explain the seemingly impossible in a reasonable way, and at the end give people a sense of enlightenment, and then come back and think that this explanation and analysis makes perfect sense. ”

"So, what I'm trying to say is that this case, while not as bizarre as it is portrayed in those novels and movies, still has its own points that are difficult to explain with common sense. But it is real, so there must be some details that we have missed or overlooked, and these details may be the key to solving the mystery. ”

Lin Feng then continued: "I think Xiao Xiao's analysis is worth learning from. The case itself may not be complicated, but it may be more complex to solve than to do. It's like solving an equation, you know the problem first and then get the final result. Solving a case is precisely a rebellious process, we have the result first, and then we have to deduce a reasonable and complete solution process to be considered perfect. ”
