Thirty years of secrets have been hidden in the waves of Linjiang Pier. Detective Chen Mo clutched the red knot left by his grandfather. The shipwreck of the Shunjiang was like an unhealed scar - gun smuggling, the shadow of opium, and the disappearance of thirty workers, which made him breathless.
The red knot loosened and tightened, the jade ring spelled out the anchor code, and from the secret compartment of the provincial office to the London auction house, the shady story pulled out a transnational chain. Grandpa's logbook, father's cellar engravings, and Captain Zhou's deathbed letter were woven into a net, trapping not only the evil people Huang Zhiqiang and Zhao Lidong, but also debts that could not be untangled for generations.
The waves of the river lap at the suspension bridge, and the red rope ties both sin and redemption. Chen Mo knew that the truth hidden in the waves had to be pulled ashore little by little with this rope.
