Chen Mu has been sitting in the archives department for five years, sorting files, filing, and getting off work every day. His life is like the paper spit out from the copy machine, one after another.
He has a secret that he has hidden for more than 20 years: he can see gray and black lines on people's bodies, growing from the heart outwards, which are malicious. The deeper the lines, the worse the person is. Those who are clean are good people.
He didn't want to be discovered, let alone use this.
Shendu is different. She is the deputy leader of the serious crime team. She does not believe in evil but only proves evidence. She has been pursuing one case for twelve years - the unsolved case of her father Shen Guoping. She thought that if she waited long enough, the answer would emerge from the cracks in the paper.
The serial case tied them together. Chen Mu couldn't avoid it, and Shen Du couldn't get rid of it. After checking, all the clues pointed to the same person: psychological counselor Xu Zhiyuan. Be gentle, be decent, and always wear light-colored sweaters.
When Chen Mu saw him for the first time, he took a look from a distance - the man's chest was clean and there was no trace at all.
No malice is required to kill someone. The secret that had been hidden for twenty years could no longer be hidden. Chen Mu finally said to Xu Zhiyuan: "Patterns can deceive people, but corpses cannot."
He relied on paper records, living witnesses, cold corpses - things that everyone could reach out and touch.
In "Pattern of Sin", a man who sees secrets and a man who believes in evidence join forces to chase a murderer who has no malicious intent.
