The video added a touch of doubt to the whole case. The three of us struggled to find out all the differences, except for the shoes and earrings, but also the weather, because in the video we found in the library, there was no sound of rain, and there was a lot of noise downstairs. Other than that, it doesn't seem to be any different. Although it is not known exactly what the date of the footage is, it is believed that the date on which the documents were deposited was the day before Casey's suicide. What the hell is going on? The things that were put there were always there, indicating that Casey herself should have put them in, so why did she put these things in there?

"Two of the same video, but different in detail, what do you think is going on? In which direction should we go next? Qin Ming and Leng Ao asked at the same time.

I shook my head helplessly: "I'm just as confused as you are, it's a strange question. Don't you think? If Casey really wanted to kill himself, why did he leave two tapes? Unless it's ...... There's a disc that was recorded before, otherwise she wouldn't have had a chance to put this thing in, would she? ”

Holding the camera, Leng Ao said lightly: "I heard that the new Lin Zi is a computer master, right?" I guess it shouldn't be too hard for her to recover the files inside, right? Give me the address of her house, and I'll have to go to her for help. ”

It seems that in addition to the video, it is the strange-looking key. Although the previous key may seem a little strange, it is not difficult to find out as long as you combine it with the trajectory of Casey's life. But this key. Where does it belong?

Qin Ming quickly found four or five of the best locksmiths, but no one could tell what the key was to the place. One of them thought it might be the key to the safe, but as far as he was concerned, he had never known of a security company that had such a peculiar key to the safe.

It took half a day to get nothing, and watching the time pass little by little, but there was nothing we could do, which made me start to get a little anxious. If you want to find out, maybe it's time to ask the mysterious person for advice.

Qin Ming was still looking through the things he had brought back, to see if he could find any clues. We used to agree on that. Casey was not suicidal. But now it seems that the problem is not just suicide and homicide. We didn't have much time left, so I frowned and decided to go to the mysterious figure first. Find out the key found in Casey's locker.

"Don't you want me to come with you?" Qin Ming was a little puzzled. Glanced at me. An expectant look on his face.

Refusal might have added a little doubt to his mind, right? After much hesitation, I decided to take him with me. Until then, though. I offered to ask him to wait for me outside, because the person I wanted to meet never liked to see outsiders.

It was a frighteningly quiet villa, and the door was guarded by armed soldiers. Qin Ming parked the car on the side of the road with a bit of surprise in his eyes. I raised the key in my hand and said with a smile: "You don't have to think about who is inside, I can only tell you that he is a person with a wide range of hobbies, and studying keys is one of his side jobs." But he has a quirk, that is, he never sees outsiders, so he can only be wronged that you are waiting here. ”

I showed my ID and after the briefing, I was allowed to enter. He lives in a small, two-story building closest to the outside. Accompanied by my secretary, who was in his early forties, I stepped up the wooden stairs to the second floor, where the old man was sitting in a sea of locks, fiddling with a safe. He smiled at me and motioned for the secretary to leave.

"There's nothing wrong with you, you little girl won't come to me. Go ahead. What is it for this time? The old man looked at me with a smile and motioned for me to sit down.

I handed over the key: "We were looking into a three-year-old case and found this. However, we invited experts to take a look, but no one can say what the key is on it, but some people guess that it may be on the safe, as for where it is, which security company issued the safe, it is not very clear. So I can only ask you to come and take a look. Where the hell is the key? ”

The old man took it, first weighed the weight of the key, then looked at the sunlight for a while, and finally found a magnifying glass, looked at the key for a long time, nodded and said: "Well, the judgment is good, it is indeed the key to the safe, but in the market, you can't see that kind of safe." ”

The old man repeatedly emphasized that the key in his hand was actually accurately named a safe deposit box provided by a bank or security company. There are many kinds of safes produced in China, but they can be roughly divided into mechanical safes and electronic safes. Mechanical performance is more reliable and more popular. However, it is also related to time, and in previous years, most of them were safes. The electronic safe is a rising star, and the electronic lock with electronic password, card and other intelligent methods is more convenient. The key I got was obviously the key to the mechanical safe, but it might have been a password. He looked at it carefully for a moment before continuing: "You see, there is a set of codes on it, which should be the code of the bank, and the location of the safe deposit box. As far as I know, there don't seem to be many banks that provide personal safes to individuals, and they are mostly privately owned. You can check it out carefully. ”

With that, the old man handed me the key. After thanking me repeatedly, I got ready to leave. However, the old man seemed to be unsatisfied, and he asked lightly: "I remember, you told me three years ago that you didn't want to investigate the case anymore, and now it seems that you have started investigating the case again, right?" ”

It's a bit embarrassing to me, because that's what I used to say. Without waiting for me to speak, I didn't expect the old man to shake his hand very freely, and said lightly: "Young people, if you can find what you like to do, it would be great, and you can't decide to give up your dream just because you get a little blow." You see, I'm already in my sixties, and I'm still researching what I really like. ”

These words made my heart warm, and I nodded hurriedly, for fear that the tears would accidentally roll out, so I hurriedly turned around and left. (To be continued......)
