When the living cannot resolve a case, the dead will speak. When debts go unpaid in this world, the underworld will collect. This is the notebook of a Yin-Yang agent, written in blood and tears. Within these pages, you will find answers: why do the last subway trains on late-night, empty lines always carry a few invisible passengers? What century-old grudge lies hidden in the dry well of an ancient house? The monsters and ghosts you dismiss as legend—they are closer than you think, lurking around you and me. Open this notebook, and it will lead you into the most real and terrifying side of China. One warning: as you read, do not look back.
