Wexford is in China on a study tour of historic sites. To his amazement, he has psychic experiences, including a vision of the body of a Chinese nobleman dead for two thousand years. Wexford's tour party is made up of strangers, but he feels tense and claustrophobic among them. Then a young Chinese student drowns during the trip. On his return to England, Wexford is called to a murder scene, and the dead woman, who has been shot, was one of those with him on his Chinese trip. There is no obvious motive, and he decides to investigate all his fellow tourists, finding hidden greed, treachery, theft, and adultery.
