Cheng Nan watched the window bolt fall with a snap, and a spiritual light suddenly flashed in his head, Cheng Nan clapped his hands excitedly and shouted, "I know." 【Big > book> package > small > said > net]"

Chengnan suddenly screamed, startling everyone present, Lin Wei's hand shook, the mop in his hand fell to the ground with a snap, and said angrily: "Don't be so startled, you want to scare people to death."

Zhang Mei was also taken aback and asked, "Chengnan, what do you know so excited." ”

Lin Wei, who was lazy in the south of the city, called from the side, walked straight to the window, pointed to the window bolt and said: "Officer Zhang, I remember that when the canteen owner died a few days ago, a police officer in your team investigated and said that in the deceased's room, it was found that the bolt hole of the window was artificially enlarged, right?"

Zhang Mei frowned, she didn't know what Chengnan wanted to say, but she did hear about it and nodded and wondered: "That's right, why did you suddenly remember this matter?"

"I know how the murderer killed someone, and then I set up such a secret room murder method" Seongnam Road.

"Ah" Zhang Mei was taken aback, looked at the window bolt, and when he saw the window bolt, his head suddenly flashed, and he wondered: "Are you talking about the problem with this window bolt, no, I checked the window at the beginning, and it was indeed trivial"

"Yes, the windows are closed, yes, but I have a way to get myself out and the windows will automatically turn back." Cheng Nan said confidently.

Lin Wei on the side also heard Cheng Nan come back that day to mention this secret room murder case, his first reaction was whether it was a ghost or not, and now when he heard Cheng Nan say this, he was immediately very curious, and said: "Oh, what can you kid do?"

Cheng Nan smiled and walked outside the window, beckoned to Zhang Mei who was in the window, and said, "Officer Zhang, do you have a toothpick for me?"

Zhang Mei glanced at Chengnan strangely, not knowing what he wanted to do, but she still took out one of the boxes of toothpicks that Xiao had just bought today and handed it over.

Xiao Gang and Lin Wei also walked strangely to the window to see what Chengnan was going to do.

Chengnan took the toothpick from Zhang Mei's hand and said, "I won't say anything about the murderer who came in from the door and killed the canteen owner.

I now talk about how the murderer escaped from the scene after killing the deceased and set up that secret room. ”

Chengnan stood outside the window and pointed to Zhang Mei who was in the window and said: "Officer Zhang was also present that day, he should know that the door was locked from the inside at that time, and there is no problem with checking the door, so the murderer is most likely to go out through this window." ”
