In Paris 1890, Lady's maid Denise le Louarn fears the worst when her mistress, Odette de Valois, vanishes from the Pere-Lachaise cemetery during a visit to her husband's grave. All alone in the great metropolis, Denise knows just one person she can go to for help: Odette's former lover, Victor Legris. When the frightened girl turns up at his bookshop and tells him her story, Victor feels there must be a simple explanation for Odette's disappearance. But as he begins to look into the matter, it soon becomes clear that something sinister lies behind events at the Pere-Lachaise.
