After a busy day, Yu Chu lay on the bed, looking at the ceiling, silently recalling in his mind.

The deceased was dressed in clothes from seven years ago.

Seven years ago, it was the time when that noble young master came to the fog capital. At that time, the young master was only twelve or thirteen years old.

Moreover, a dress from seven years ago, why can the proprietress blurt out the year of the dress?

After wearing clothes for several years, most people forget what year it is.

Unless it's particularly impressive.

Old Jack knew what that noble young master had done seven years ago. A lot of things that are very excessive.

It is not surprising that the aristocracy did not treat commoners as human beings at all, and would play cruel games. But is there any connection between all these things?

Why did the murderer kill?

If there is a reason, then there are traces to follow, but if there is no reason, it is really a pervert, and there is no law in killing people, so who has any way......

There's no way to count on Old Jack anyway.

Yu Chu closed his eyes, lay down for a few minutes, and slowly recalled the dead person he saw today.

She observed a lot, in addition to the shabby clothes, there was also the straight silver knife, which was inserted very accurately and beautifully, and the blood around the corpse was not stained with any traces, and even the handle of the knife did not leave fingerprints......

She suddenly opened her eyes again, sat up from the bed, and remembered that there was something she hadn't noticed.

But it was already dark, and now no one in the city dared to go out at night, which meant danger.

Yu Chu hesitated for two seconds, but still put on her clothes and got up and went out - she had experienced a lot of blood in the world in front of her, but there was nothing to be afraid of.

It's just a little cold and swishing on the body.

She walked out of the detective agency and walked to the scene of the crime in the night, the body had of course been removed, and there was only a pool of blood in the entire dark alley.

She crossed her arms, walked over to the bloodstain, and then crouched down by the wall, her fingers touching the blood sprayed on the wall, and feeling a mark that had been cut by a knife.

When she was just recalling the scene, she suddenly remembered this trace. Because the attention was on the deceased at that time, and not much else, and there were often scratches and graffiti on the wall, the marks were inconspicuous.

It's just that because the traces look a little new, she looked at it twice, and just when she was lying on the bed and remembered, she suddenly felt that something was wrong.

The new scratches, with sharp edges and corners, are most likely left by the silver knife, isn't it very likely that they were left by the murderer? This pervert is careful and obsessive-compulsive, and it is impossible to accidentally leave any traces.

It is only possible that he did it on purpose.

She felt the slender scratch with her fingers, and felt the fork at the end—it was an arrow.

The direction of pointing is ......

Ahead, it seems that there is only a detective agency.

What does it mean to point to a detective agency?

Does it indicate the next step?

He's going to move the detective agency......

But for a pervert, who would he want to kill in the detective agency? If it's random killing without a trace, then she has no clue. But if it really has something to do with the many bastard things that that noble young master did seven years ago...... What exactly does it have to do with it?

Old Jack knew something about the past.

And the original owner, who had not been apprenticed to Old Jack back then, was only fourteen years old that year.

It's just a little girl.
