Set in 19th century France, THE LAST MISTRESS chronicles the love affair between tempestuous Spanish mistress Vellini and distinguished, well-bred Ryno de Marigny. Ryno's attempt to remain faithful to his wife Hermangarde, a highly regarded young woman of the French aristocracy, profoundly fails as Vellini reappears in Ryno's life, offering him the passion and emotional connection he lacks in his marriage. His reluctant obsession with Vellini eventually overtakes his conscience, as he succumbs to the deceitful path of infidelity.
