# Duc de Sairmeuse — Monsieur Lecoq character guide > Duc de Sairmeuse in Monsieur Lecoq by Émile Gaboriau. **Role:** supporting **Also known as:** Monsieur le Duc, Sairmeuse **First appearance:** 0000-monsieur-lecoq ## Snapshot A proud returning nobleman who mistakes a handful of hired shouts for a village's love and cannot imagine being wrong. ## Who they are The Duc de Sairmeuse rides back into a transformed countryside convinced that the old feudal prestige still holds, and he reads the Chupin family's noisy welcome as proof of it. His son Martial sees the pretty cottages and skeptical peasants for what they are; the duke shrugs off every omen, too vain to renounce an illusion. That blindness places him at the center of the gathering storm, the aristocrat whose return ignites the resentments the Lacheneur conspiracy will try to exploit. ## Relationships ### [Martial de Sairmeuse](https://www.betterreads.dev/discover/monsieur_lecoq_se/characters/martial_de_sairmeuse) _family_ The Duc de Sairmeuse is Martial's father, a proud and manipulative aristocrat who pressures his son to uphold family honor and class interests. ### [Lacheneur](https://www.betterreads.dev/discover/monsieur_lecoq_se/characters/lacheneur) _rivalry_ The Duc de Sairmeuse and Lacheneur are bitter enemies, as the Duc usurped Lacheneur's family estate after the Revolution. ### [Lacheneur](https://www.betterreads.dev/discover/monsieur_lecoq_se/characters/lacheneur) _rivalry_ The Duc de Sairmeuse and Lacheneur are bitter enemies, as the Duc usurped Lacheneur's family estate after the Revolution. ### [Martial de Sairmeuse](https://www.betterreads.dev/discover/monsieur_lecoq_se/characters/martial_de_sairmeuse) _family_ The Duc de Sairmeuse is Martial's father, a proud and manipulative aristocrat who pressures his son to uphold family honor and class interests. ### [Martial de Sairmeuse](https://www.betterreads.dev/discover/monsieur_lecoq_se/characters/martial_de_sairmeuse) _family_ The Duc de Sairmeuse is Martial's father, a proud and manipulative aristocrat who pressures his son to uphold family honor and class interests. ### [Lacheneur](https://www.betterreads.dev/discover/monsieur_lecoq_se/characters/lacheneur) _rivalry_ The Duc de Sairmeuse and Lacheneur are bitter enemies, as the Duc usurped Lacheneur's family estate after the Revolution. ## In the story ### [XXI](https://www.betterreads.dev/discover/monsieur_lecoq_se/chapters/xxi) Owner of the Hôtel de Sairmeuse, where a reception is being held;
