River of Wisdom: The Burning Embers of Bianjing is a historical mystery novel set against the backdrop of the famous Northern Song painting Along the River During the Qingming Festival. Rooted in the bustling streets of Bianjing in the third year of the Xuanhe era, the story begins with the "Plum Blossom Boat Case" and unfolds into a series of intricate mysteries entangling the imperial court, the martial world, and ordinary city life.
The protagonist, Zhao Buyou, known as the finest legal mind among the common people, is unexpectedly drawn into the bizarre case of the Plum Blossom Boat on Rainbow Bridge. A mysterious black ship behaves strangely in the dense fog, its crew vanishes without a trace, and clues such as a severed hand floating in the water, forbidden weapons belonging to the Imperial Guard hidden in a secret compartment, and a silver hairpin embroidered with plum blossoms lead him into a tangled web of smuggling, murder, and political conspiracy. As the investigation deepens, the disappearance of Taixue student Liu Erlang, the secret movements of Chu Lan, a woman from Jiangnan, and the vast network behind corruption in river transport gradually come to light, even implicating collusion between the chancellor's faction and the forces of the martial world.
With delicate prose, the novel recreates both the splendor and the undercurrents of Northern Song Bianjing: the bustling traffic on Rainbow Bridge, the splendid embroidery workshops on Panlou Street, and the clandestine dealings at Liuxi Wharf all intertwine with the common folk's struggle to make a living and the power games of the imperial court. As Zhao Buyou and his "case-solving team," made up of his younger sister Zhao Ban'er, his younger brother Zhao Mo'er, and others, unravel one mystery after another, including the "Sachet Case," the "Plum Blossom Boat Case," and the "River Transport Smuggling Case," they must face both overt threats and hidden dangers, from a scar-faced assassin to corrupt county officials. They must also seek the truth amid the struggle between imperial power and political factions, exposing the shocking conspiracy concealed beneath the prosperity depicted in Along the River During the Qingming Festival.
