It was a heavy wooden door with a revolving handle lock and a small built-in lock.
It was a common lock. On one side was a square push button for locking, and in the middle was a small round button. After pressing it, the latch would bounce back.
Following the direction of Miyamoto Ami's finger, there was an inconspicuous small hole less than 10 centimeters above the embedded door lock.
There was a vertical groove on the square handle of the door lock. Babsi looked at this and said," I finally understand why the killer didn't turn the handle lock, but used an embedded lock.
The door is locked." Miyamoto Ami also said confidently,"Of course, this is related to the murderer's entire setup!”Tan Hao was confused by what he heard.
"What are you talking about?" I don't understand at all.”Babsi didn't reply, instead carefully searching the surroundings.
Especially on the floor.
Miyamoto Ami pointed at the hole and asked Tan Hao,""Look at this small hole. It looks like it was nailed in by something?”
"Needles?"
"Don't you think it's too thick if it's a needle?”
"Nail? No, it seems too thin."
"Stop guessing. I'm telling you, it's a pushpin.”
"Pin?"
"That's right, and the groove on this pushing hand was also man-made later.”
Babsi said," We didn't find any pushpins when we searched the crime scene. They're not there now either. They might have been taken away by the murderer."”
Tan Hao said,"Impossible, how can a pushpin set up a secret room?"”
Babsi shook his head and said,"Yamei, explain it to him."”
"My great detective," Miyamoto Ami sighed,"you don't even know about such a simple secret room layout?" First, he nailed a pushpin on the embedded door lock.
Then, he used one end of the silk thread to tie the pushpin, and the square push hand in the middle to make the silk thread fit into the groove. Then, it went around the door handle and reached out from the keyhole below.
You just need to stand outside the door and pull the other end of the rope, and the embedded door lock will automatically lock. The secret chamber is complete."
Tan Hao thought about the process and said,"Reaching out from the keyhole below, isn't it too difficult?"”
Babsi said," It's not big at all, because the lock has been hollowed out in advance. It's always been a broken lock, otherwise the owner of the room wouldn't have done it again."
A small embedded door lock was installed in one fell swoop.”
Tan Hao twisted the door handle with his white gloves, and as expected, he did not exert any strength. He had never opened this door before, so it was inevitable that he did not know the mysteries behind it.
"Where's the pushpin?" he asked. According to your deduction, the pushpin should still be in this room.”
"The murderer must have returned to the crime scene and taken it away," Babsi said.”
"Impossible," Tan Hao said. Wouldn't his secret chamber be set up in vain? Besides, the door was already locked. How could he get in?”
Babsi said," So, the murderer was smart enough to enter the room at the same time that the body was found and take away the thumbtacks that were important evidence.”
"Impossible! Absolutely impossible!" Tan Hao shouted. She can't be the murderer!" Of course, he knew who Babsi was suspecting because he had replied after the incident.
There was only one suspect at the crime scene-Fang Xiaoyu! Tan Hao was agitated. He continued,"Fine, even if she's the murderer, how do you explain a thin and weak woman?"
How could a woman make a 1.78-meter-tall man put his neck on the rope on the beam? How could he explain that Liu Zekuan heard the voice of the living Liu Jingyang?”
Miyamoto Ami saw that Tan Hao's face was red and quickly went forward to persuade him,""Tan Hao, calm down. Babsi is just suspicious, we need to be suspicious when we're investigating cases
Everything!"
Tan Hao didn't listen to her at all and said,""Just you wait. I will find out everything. I will find out who the real murderer is! I'll prove to you that she's innocent
!”After saying that, he slammed the door and left!
