1994, Wuling, a small border town.
Detective Captain Lin Yi grew up in a Taoist temple and learned the art of observing people - when a person lies, his eyes will turn to the right, and when a person is poked in a painful spot, he will have a freezing reaction for a few tenths of a second.
Corpses in caustic soda barrels, cannibalism in rental houses, ashes in incinerators... 12 Strange cases, 12 lives, all clues ultimately point to the same person - overseas smuggler Su Laizi.
The fake nails he sold killed people; the drugs he sold turned people into ghosts; the murderers he forced out burned people to ashes.
Lin Yi touched the unburnable fake nail in his pocket and knew that this battle had just begun. (This book is a work of fiction.
