Multiple "perfect suicide cases" occurred in Lukang City one after another.
There were no obvious signs of homicide on the deceased, and there were no signs of intrusion at the scene. The cause of death was suicide. But next to each corpse, there is a book that has long been out of print - "Dialogue with the Abyss".
The author of this book is Fang Yuanshan, a leading figure in psychology who jumped to his death five years ago.
Lin Ying, 34 years old, is the chief expert of the Psychological Crisis Intervention Center. She could see through everyone's thoughts, but she could not understand the words left by her mentor Fang Yuanshan before his death: "Lin Ying, don't save me."
For five years, she relied on two medications to stay asleep.
Cheng Yue, 29 years old, deputy captain of the criminal police detachment. Colleagues call him the "Living King of Hell" - not because he is fierce, but because he is ruthless. He was so cruel that he didn't even let himself go.
No one knew that his father jumped from the twelfth floor twenty years ago and died with the same book on his bedside.
When the city bureau handed the case over to them, Cheng Yue said: "Don't involve psychologists."
Lin Ying sat down and glanced at him: "I have checked your father's case."
For the first time, the word "fear" appeared in Cheng Yue's eyes.
All clues point to the same name - Gu Baizhou. The founder of the psychological counseling organization "Eye of the Abyss", Fang Yuanshan's last student, and Lin Ying's fellow junior.
He is gentle, smart, and impeccable. Every step he took was within the legal framework, and there was no evidence to accuse him.
But he can make a person willingly die without knowing it.
"This is not suicide," Lin Ying said. "This is murder. But the murderer didn't use a knife, but a human brain."
Cheng Yue asked her: "Can you prove it?"
"Can't."
"Then what can you do?"
"I can make him see that there are people lighting lamps in the abyss."
This is a story about the abyss.
It is also a story about light.
Some people are lost in the abyss, and some people are lighting lamps in the abyss. Some people use psychology to control life and death, and some people use psychology to bring people back.
"Don't carry it alone."
This is what two people who climbed out of the abyss said to each other in the darkest moment.
