The Triumphs of Eugène Valmont

Eugène Valmont introduces himself as a former chief detective of the French government who now plies his trade in London. He explains that the case he is about to recount has haunted Europe for more than a century, tied to a long‑lost diamond necklace discovered in an attic at the Château de Chaumont. The narrative promises a blend of meticulous sleuthing and the lingering superstitions that surround a treasure once meant for Marie‑Antoinette herself.

The story opens in 1893, a year of plenty for France, when the unexpected discovery of five hundred glittering diamonds set the nation’s gossip mills into overdrive. Valmont hints at a chain of misfortunes that befell everyone connected to the jewels—from a ruined jeweller to a doomed countess—suggesting that the gems may carry a malevolent influence. As the detective begins to trace the necklace’s tangled history, readers are drawn into a maze of clues, bankrupt aristocrats, and a secret that could change the fate of those who seek it.

Through crisp period detail and Valmont’s dry, self‑aware voice, the tale feels both a classic whodunit and a commentary on ambition and folly. Listeners can expect a steady unraveling of motives and alibis, punctuated by the occasional flash of the diamonds’ blinding allure. The early act lays the groundwork for a mystery that is as much about human nature as it is about a glittering crime.
