During the Jinghe era of the Dayong dynasty, laws and regulations were comprehensive and trade routes flourished, yet dangerous undercurrents swirled beneath the imperial court. On a snowy night in Yunzhou, a woman was found dead in an abandoned temple. The scholar Wei Shubai confessed, a bloodied knife in hand, and the case file was so complete it seemed beyond reproach. But Shen Zhaolin, a young clerk, spotted an out-of-season epiphyllum in the victim’s palm, and with it the first crack between the law and the truth.
The law is a winter night, and a chart reveals all. If the truth blooms for only an instant, he will capture its final shape before the flower fades. He draws “forensic charts,” linking people, objects, places, times, and evidence to illuminate the hidden threads beyond the case files.
From a wrongful conviction in Yunzhou to the Nanjing mint, from the Huai River transport gangs to Chang’an’s powerful elite, from the mysteries of fragrant medicines to the undercurrents of the grain market, Shen Zhaolin and his companions investigate one lead after another, finally closing in on a vast web of darkness that uses the law as a tool and human hearts as its game board.
