In the shadow of the modern city, a folk reasoning team moves forward among serial unsolved cases, social weird phenomena and the gray of justice. Ten major cases of different styles involve multiple complex interest groups and far-reaching historical entanglements. As the case progresses, team members continue to face their own secrets, family ties, and crises of faith. Each part has an independent main line of major cases, and at the same time connects the ultimate mystery throughout the book "The Case of the Disappearance of Mother". All story lines finally converge in the tenth part, and the truth is revealed, showing the huge tension between legal principles and human relationships.
