Paris, 1900. Comte de Landois has ordered his wife Marguerite to travel from Paris, to join him in the Loire Valley. Her journey into the pastoral quiet is shattered by the appearance of a dead man on the railway tracks. Who is he? And why does Marguerite's young traveling companion pale when she sees him? When the Comte presents Marguerite with an adopted baby, and his sudden friendship with local clerics imposes new rules and regulations on her behavior, things start to take a sinister and troubling turn. The sister of her young companion goes missing and Marguerite calls in Chief Inspector Durand to help hunt her down. Together, they begin to unravel a tangled world of small-town secrets, disturbing obsessions and unholy loves.
