During the St John’s Eve celebrations of 1834, Benjamin January learns that his sister Olympe has been arrested for murder. The evidence is slight, but Olympe is a defiant woman of colour associated with vodou, making her an easy target for officials who have little reason to provide her with a fair hearing.
January searches among markets, cemeteries, religious communities and Creole households while graveyard dust left at his door warns him to stop. To save Olympe, he must separate spiritual belief from calculated intimidation and uncover who benefits from a killing concealed by fear and racial prejudice.
