In the twenty-sixth year of the Republic of China, the dense fog in Jinmen persists all year round. At the intersection of the concession and the old city, strange cases occur frequently and ghosts hide in people's hearts. Shen Yanzhi, a Chinese detective, combines Dickong's wisdom in investigating subtle cases and Sherlock Holmes's logical deductions. He can look for flaws in clues and discern the truth in the treacherous nature of human relationships. From secret room poisonings to serial mysteries, every case is a dilemma of human nature, and every step is closer to the old grudges. He used evidence as a blade and logic as a lamp to break through the layers of disguise and expose the so-called "perfect crime". In the thick fog, he guarded the right path in the world and uncovered the undercurrents and secrets that had been buried for ten years, composing the legend of the Jinmen Detective.
