The Hanging Beam Conspiracy

Ten years ago, three unresolved cases in southern Fujian: three officials were hanged from beams, each scene left with a red cloth strip, and the killer vanished without a trace. Ten years later, Chen Guodong, deputy director of the Binhai City Planning Bureau, dies by the same method. The red cloth strip reappears. Lu Weimin from the officialdom, Su Mo from the underworld, and Lin Shen from the laboratory are bound together by this case. The hands are still moving. — Description from novelcodex.org
