At twenty-five, genius detective Shen Jin has astonishing powers of observation. In just six months on the job, he has solved three cold cases and become the brightest new star in the major crimes unit.
He suffers from inexplicable headaches and intermittent memory loss. At bloody crime scenes, he always feels a strange sense of familiarity deep inside.
The flawless serial murders he investigates are the work of a meticulous killer with impeccable counter-surveillance skills. The killer never harms the innocent, only punishing the wicked.
Then the clues finally come together, and the truth shatters everything:
The killer he has pursued across countless miles has never been anyone else.
It is another self, buried in his bones: cold-blooded, obsessive, and shaped by crime.
In the name of the law, I hunt down the sins within myself.
The killer I’ve been chasing has always been me.
The plot is suspenseful and interesting.
