Plot introduction
Just returned from years overseas on a secret mission, Albert Campion is relaxing in his bath when his servant Magersfontein Lugg and a lady of unmistakably aristocratic bearing appear in his flat carrying the corpse of a woman. At first Campion is unwilling to get involved, but he is forced to bring his powers of detection to bear on the case, and to solve not only the mystery of the murdered woman but also the alarming disappearance of some well-known art treasures. Campion discovers the clue to the mystery by tracing two bottles of a very rare wine.
