The Tainted Line consists of sixteen chapters. A cold case in a narrow alley in the old city sets the story in motion, unfolding a web of fate that stretches across more than a decade. From the bloodstained old backpack that raises the first suspicions on a rainy night in Chapter One, to the buried clues falling into place beneath the daylight in Chapter Sixteen, the story steadily explores the gray zones hidden in the cracks of everyday life and the tangles of human nature. In the opening chapters, the protagonist, an ordinary auxiliary police officer, steps into the fog. Statements from street thugs and anonymous evidence from an abandoned construction site gradually lead him to the interests deliberately erased from the story of the city’s governance. In the middle chapters, fragmented recollections from different witnesses piece together several secret cases swept up in the tide of corruption over the years. The protagonist’s own long-buried family history also slowly intertwines with the hidden tainted line. In the later chapters, as various forces vie for advantage and probe one another, the protagonist tears open the tangled web lurking beneath the city’s seemingly peaceful surface. Forced to navigate the dangers of choosing between the law and personal loyalty, he ultimately uncovers the complete truth behind the original murder and uproots the entire network of corrupt interests that had remained hidden for years. All sixteen chapters fit together tightly. Through grounded details and stark storytelling, the book portrays the resolve and struggle of those standing at the edge of the abyss, while revealing the faint but undying light of justice amid the surging waves of corruption.
