Shan Tao Yun, now the reluctant constable of a remote Tibetan town, has learned to expect the impossible at the roof of the world, but nothing has prepared him for his discovery when he investigates a report that a nun has been savagely assaulted by ghosts. In an ancient tomb by the old nun lies a gilded saint buried centuries earlier, flanked by the remains of a Chinese soldier killed fifty years before and an American man murdered only hours earlier. The Tibetans are terrified, the notorious Public Security Bureau wants nothing to do with the murders, and the army seems determined to just bury the dead again and Shan with them. .
