At its heart, this novel is about “the search for truth.” It explores the boundaries between justice and revenge, the struggle between reason and obsession, and the fight between institutions and corruption. As Qin Chuan investigates a series of murders, he must face the hunt laid by criminal forces and break free of the shackles of his own trauma. Caught between institutional rules, human weakness, and the whirlpool of fate, he must forge a lonely, courageous path as an investigator. Through mysteries nested within mysteries and a hair-raising pursuit of the killer, the story conveys its central message: “True justice is not a perfect outcome, but the resolve to persevere throughout the search.”
