A VANISHED KILLER REARS HIS HEAD When several students from a prestigious private school flee campus overnight, the Yancheng Municipal Public Security Bureau launches a search—only to find one of the runaways murdered. As Sergeant Luo Wenzhou and his team investigate, they uncover a cruel ritual carried out by the students’ own peers, and powerful parents who would rather the case be forgotten. But the ritual is only the beginning. The boy’s death is soon linked to a series of highway murders from more than a decade earlier. Following that trail, it becomes clear that all the bureau’s most recent cases contain a common thread…a thread tied to Fei Du.
