Paris. The late reign of Louis XIV. A death that should have been ordinary.

On 31 July 1672, a man is found dead in his Paris rooms—and an inventory opens a locked cassette that should never have been opened. Inside: “diverse vials” and nine letters linked to Marie-Madeleine d’Aubray, Marquise de Brinvilliers. In the official account, those letters point to an unthinkable claim: that a noblewoman poisoned her own father (1666) and two brothers (1670). And the vials? “Virulent poisons” said to leave little trace—perfect for a world where illness already looked like death.

What begins as a private scandal becomes a matter of state, tangled with money, influence, and ministerial rivalry. Brinvilliers runs. Paris hunts. And when the machinery of justice finally closes around her, “truth” is produced through procedure—confession, coercion, and spectacle.

The Marquise of Poison is true crime and history: it follows the paper trail, keeps the legal process visible, and separates what can be shown from what is merely said—refusing the easy, sensational version of a case that terrified a city.

Content note: murder, coercion, judicial violence, and execution.
