Crime scene: 162 mystery solving puzzles to find out who the murderer is

Chapter 132
It was already 11:2, Qingmei went up to the second floor gently, and tiptoed towards her room.At this time, she suddenly heard the folding table overturned and the sound of the tea set clanging to the ground in Yuyan's room.

Yu Yan is a salesman for a cosmetics company. Because of her business relationship, she knows many customers.Recently, a middle-aged man often came to her. Sometimes the two were intimate, and sometimes they quarreled upside down.Qingmei has long been used to it.

But today I didn't hear that man's rough voice, nor did I hear Yu Yan's cry.Before Qingmei could figure it out, suddenly, she heard "Help, help..." in a low voice.Listen again, but there is nothing.

After hesitating again and again, Qingmei knocked lightly on the door of Yuyan's room, but there was no answer, and the door was locked.There was the sound of slippers on the stairs, and Qiu Yun from the first floor walked up suspiciously.

"Qingmei, was it my cousin's voice just now? Qiuyun and Yuyan are cousins, and she lives directly under Yuyan.

"It seems to be. I knocked on the door, but no one opened!"

"Stay here and watch, I'll go down and call the landlord," Qiu Yun said decisively.

Fortunately, the landlord lived next door to the apartment, and soon came up with a key.When Qingmei saw them, she immediately reported nervously: "There has been no sound, and no one has come out!"

The landlord opened the door, and the scene in the house was astonishing.The folding table was overturned, and the fragments of teacups were all over the floor.Yuyan lay motionless on the ground, with a long silk stocking strangled around her neck, apparently dead.There was no sign of anyone in the house, and the windows were ajar.The landlord immediately dialed 110.After a long time, Qiu Yun came to his senses first, "Did the murderer jump out of the window?"

"Impossible, there is a cliff under the window." The landlord denied her opinion.Qingmei walked around the corpse carefully and pushed open the door and window to look. There was an iron pipe for running water outside the window, but it was rusty and full of holes.

"Could it be the sound from the tape recorder?" Qiu Yun said.But the three did not find the tape recorder in the house.

How did murder escape?
[Answer] The murderer was the younger sister of the deceased. She killed the deceased in the house first, then tied a string on the table leg, passed through the open window, and then passed through the hole of the iron running water pipe to her own room , When Qingmei came up, she pulled the rope and turned the table over, making a noise. The rope was also dragged down from the iron running water pipe, and she yelled for help in a very low voice through the iron running water pipe, so Qingmei heard the sound of help being very small.
