Gu Xin came to the table, smelled the half-drunk cup of tea, and suddenly found that there was a handkerchief under the table, and a mandarin word was embroidered on one corner of the handkerchief.

She didn't pick it up, and the book says that she can't touch the things on the scene.

She suddenly found that her observation was still too one-sided, maybe there were other clues in it, and for a while, Gu Xin's interest in solving the case came, so she looked here and there in the house.

In addition to the footprints on the window and the handkerchief on the floor, she also noticed that there was something wrong with the walls of the house, and the back of the house, which was obscured by a painting, turned out to be empty.

If she can't touch anything at the murder scene, she can go to the next room to take a look.

So, Gu Xin came to the next room and determined the same location as the painting on the wall at the murder scene, there was also a painting there, and it was crooked.

She called a servant: "Take this painting down and push it hard." ”

Officer: "? ”

Gu Xin: "Don't pestle, you push it, I'll let you do it, what's the wrong thing for your boss to find me." ”

The official stepped forward and took down the painting.

Gu Xin stepped forward and knocked on the wall, but it was empty, and then let the officials push it.

This push is only a little loose.

The officials were stunned.

Gu Xin: "Make a little effort." ”

The official face was red, although Princess Xinxin was very powerful, but I was the official of Jingzhao Mansion, unlike other people who were in a trusting relationship, I was selected layer by layer by strength.

So, he did his best.

A hole was introduced, and this hole could pass through a small person, and a tall and thin person could pass through it.

Gu Xin came to the table in this room and looked at the foot of the table, there was dust, there were traces of movement, and there were half shoe prints on the table.

She couldn't help but speculate that Li Yuyan was not the murderer, the murderer stunned Li Yuyan, killed Xiaocui, and then put it in Li Yuyan's hands, and then imprinted a footprint on the window, piercing through the hole in the wall to the next room.

In this way, the murder scene is locked, and the person investigating the case will think that someone has escaped from the window when he sees the shoe prints, and it is estimated that no one thought that Bai Er was on the opposite side of the window, and he didn't see anyone escape.

In terms of time, they arrived across the street and saw Li Yuyan, Bai Er was there, and then they slowly crossed the street, said a few words downstairs, and went upstairs.

That is, when she was crossing the street, Li Yuyan entered the room and drank tea and fainted.

She went downstairs, Xiaocui was killed, the murderer arranged the scene, escaped through the hole in the wall, and she went upstairs.

When she went upstairs, the murderer was still blocked by her in the next room.

After she entered the house, Dongxue was standing outside the door, and it was definitely impossible for the murderer to escape.

Later, she talked to Bai Er, talked to Li Yuyan, and then Dong Xue argued with Xiao Er.

It is likely that Xiao Er did not come up from downstairs, but came out of the next room.

If he really came out of the next room, he turned around and went to this room, anxiously asking about the situation, and Dongxue would only think that he came up from downstairs.

That's right, most likely.

Fortunately, she asked the shopkeeper to leave all the things to do in time, otherwise this little two ran away, where to find it?

Gu Xin knocked everywhere on the wall of this room again, except for the connection with the next room, everything else was solid and complete.

She felt more and more that it was the little two.

Let the servant look at the room as well, and then she went downstairs.
