The Marchioness of Brinvilliers, the poisoner of the seventeenth century

A dramatic historical romance set in old Paris follows a web of intrigue around a notorious poisoning conspiracy, tracing arrests, escapes, secret rendezvous, and judicial investigations. Interacting groups — conspirators, suspects, medical and legal figures, and desperate associates — pursue revenge, protection, and advantage through deception and passionate entanglements. Scenes shift from crowded streets and river mills to catacombs, prisons, and country estates, unfolding discoveries and stratagems that lead to capture, exposure, and final reckoning while maintaining a tense, atmospheric portrait of social danger and moral collapse.
