Code Name: Red Silk

Three years ago, a secret operation wiped out an entire twelve-person special forces squad. Gu Lin, its sole surviving captain, bore the infamy of being the “Lone Wolf who got them killed” and spent three years suspended pending investigation. At the same time, Song Ling, the provincial department’s youngest criminal profiler, accidentally killed her partner Lin Kai during an arrest. She gave up writing about her work, was demoted, and lived with guilt and nightmares.

Three years later, an unidentified woman’s body is found in the city moat, with a string of mysterious numbers carved into her palm. The numbers turn out to be Song Ling’s own invention, her “criminal gene marking system,” a code known only to her and her late partner. Meanwhile, the tactical hand signal on the victim’s arm points to Gu Lin’s Lone Wolf assault team.

Two people who should never have crossed paths are bound together by this corpse. Suspicious of each other, they are forced to work together, only to find that every clue points to the same place: Blackwater Town, a border settlement where twelve soldiers were buried.

And even deeper mysteries are beginning to surface: Lin Kai, though dead, seems to have left traces behind; the drug lord “King of Hell,” who should be in prison, had secret dealings with Gu Lin; and the last person to access a top-secret file with its key pages torn out was none other than Lin Kai himself...
