First appearance: monsieur lecoq
As a supporting figure in Monsieur Lecoq, Duc de Sairmeuse is not background color—the story leans on what they do once the chapter opens.
Owner of the Hôtel de Sairmeuse, where a reception is being held; his valet Otto is sent to inquire about the disturbance.
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.
