Perfect Crime

The perfect crime? Hou Dasheng said: It does not exist! There has been an unsolved case in Jiangcheng for ten years, and the murderer's carefully arranged scene is watertight. The forensic doctor shook his head. The surveillance video was full of snowflakes. Only Hou Dasheng stared at an ordinary button in the evidence bag and sneered: "If you don't want others to know, you have to do nothing yourself." He firmly believes that no matter how perfect the stage is, it will eventually fall apart. When everyone gave up, Hou Dasheng smelled traces of the devil from the worn patterns on his buttons. The sun pierced the dark clouds, and he whispered to the empty interrogation room: "You can't escape." (This story is purely fictitious and any similarity is purely coincidental.)
