But before we walked in, I saw a familiar figure: Zhao Yan? What is she doing here? She obviously saw me at the same time, and a trace of uneasiness flashed on her face, but she still quickly greeted me, and finally her gaze stayed on Qin Ming's face.

"How did you get here? It won't be for the ...... Senior sister's case, right? That was all three years ago, how can you still ......" Zhao Yan asked with a puzzled expression, and while saying this, she didn't forget to look at Qin Ming twice.

I nodded: "Let's take a look here, I heard that the house has not been touched since it was unsealed, so let's take a look." ”

"No one has touched it all this time? Didn't you say that the house had already been rented? Zhao Yan looked at us with a look of surprise and asked curiously, "It seems that there has never been anyone living in it, but I have been here a few times, and the door is locked." ”

"That house has always been rented by Ouyang Song......" Qin Ming interjected faintly on the side, he didn't seem to pay too much attention to the strange gaze in the eyes of the girl in front of him who was talking.

Zhao Yan's expression became incomprehensible at that moment, and she took out her mobile phone with a wry smile and glanced at it: "I really can't imagine that he has such an infatuated time." But it's no wonder that he was very obsessed with his senior sister at the beginning, but he didn't expect him to be so affectionate. ”

This is a very tightly managed apartment, perhaps because of its close proximity to the school, and the manager of the apartment is very careful. To enter and exit here, you must swipe the access control card, and if you do not have an access control card, you must register with the security guard. Observed at the door for a while. I've noticed that not all people need to swipe their access cards, because if you wait there for a while, you can go in with someone coming out or going in.

The security guard was a very vigilant young man, we only stayed outside for about a few minutes, he kept an eye on Qin Ming's every move from time to time, and when we walked in, he didn't hesitate to block our way.

After showing the ID and confirming our identity, he let us in with an apologetic face. Not bad. It is true that the management is relatively strict. Strange faces appear here, and they are easy to spot.

On the third floor, to the left, closest to the stairs, is the room where Casey lived, supposedly after Casey's parents moved out some of her belongings. It has always been the same. According to Matsuko himself. When paying rent every year. He would ask someone to come and clean it. The door lock is the kind of round hole lock, and after it is closed, it is impossible to see through the crack in the door. I wonder if the town wants to say something. Only to find that the place near the top of the door is a piece of foggy glass, through which you can vaguely see the situation in the room, which not only maintains the lighting in the room, but also maintains the privacy of the residents. However, this does not seem quite right, because in the transcripts of the time, all the people mentioned that they saw the inside through the crack in the door. Qin Ming obviously had the same doubts as me, so with these questions, we used the key given by Songzi to open the door.

It's been almost a year since the last cleaning, so the room is full of dust. The sofa facing the door was still there, and according to Matsuko, it was the same as the original couch, which had been thrown away a long time ago, and it was only at Matsuko's insistence that the identical one was moved back from somewhere else. The living room is still full of all kinds of books, most of them related to the piano, and in addition to these, there are also a few books on chicken soup for the soul.

Underneath the window was a desk with a photograph of Casey, but it was also covered with a thick layer of dust, a picture taken after Casey's performance. Casey in the photo is obviously excited, standing next to her are several classmates who participated in the performance at the same time, and Sun Changqing is standing on the very side. In the drawer was a thick pile of sheet music, some of which had been copied from my own book, and other notes taken during class, and nothing else. It seems that Matsuko is right, and Casey's family didn't pay much attention to these books and the like, so they were able to keep them intact.

The room was very simple, according to the information given by the police at the time, it was a small camera that recorded Casey's last message, which was placed on the chair behind the door. When I pushed the door open, the camera fell to the ground. What is also certain is that the door was not locked, so the first person to find it was able to push it in. There was no sign of anyone else entering, and there was nothing suspicious.

"What are you thinking?" Qin Ming opened his mouth to break the silence, his expression was very solemn.

I shook my head: "It's hard to imagine that a person who is ready to commit suicide would do so much work. By the way, Matsuko said that everything here, something valuable, has been taken away by Casey's family. But they didn't take this photo? It seems that Matsuko has some good things to say, Casey's family, the relationship with her is unusual, or maybe they left these things for other reasons. If it weren't for Matsuko's insistence, I'm afraid it would be difficult for us to see the scene again. ”

"But here...... It's been three years, can any clues be found? What's more, although the poet is infatuated, he invites someone to clean here every year, and many clues have been erased. Qin Ming said helplessly.

Good intentions sometimes do bad things. I opened the curtains, this is the third floor, but there are no tall buildings in front of and behind, so the view here is good. It is about 100 meters away from the building next door, and you can see every move in the opposite building. Downstairs is the lively road, so you can see the cars coming and going downstairs. Perhaps because of a coincidence, I saw Zhao Yan standing on the side of the road, looking at her phone while crossing the street. She...... Did you come here to find someone before? Why did you leave so soon?

"It's a good sight here." I frowned, "I'm afraid Casey knew early on that someone was watching her every move." You see, go through here, cross that road, and over there is the gate of that school. And if I remember correctly, about 100 meters to the left of the gate, there is the boys' dormitory. Matsuko is there to watch Casey every day, right? There is such a person who is obsessed with himself, sometimes it is quite scary to think about. ”

"Scary? I thought you would say touched. Qin Ming said, "Didn't you say that girls are the easiest to be moved?" (To be continued......)
