Monsieur Lecoq, Volume II by Emile Gaboriau

The Duke de Sairmeuse was one of those men who remain superior to circumstances. He was possessed of vast experience, and great natural shrewdness. His mind was quick to act, and fertile in resources. But when he found himself immured in the damp and loathsome station-house at the Place d'Italie, after the terrible scene we have just recalled, he felt inclined to relinquish all hope. He knew that justice does not trust to appearances, and that when an investigating magistrate finds himself in presence of a mystery, he does not rest until he has fathomed it. He knew only too well, moreover, that if his identity was established, the authorities would endeavour to discover the reason that had led him to the Poivriere; now he could scarcely doubt but what this reason would soon be discovered, and, in that case, the crime at the Borderie, and the duchess's guilt, would undoubtedly be made public.

This meant the Assize Court for the woman who bore his name -- imprisonment, perhaps execution, at all events, a frightful scandal, dishonour, eternal disgrace! And the power he had wielded in former days was a positive disadvantage to him now, when his past position was filled by his political adversaries. Among them were two personal enemies, whose vanity he once had wounded, and who had never forgiven him. They would certainly not neglect the present opportunity for revenge. At the thought of such an ineffaceable stain on the great name of Sairmeuse, which was his pride and glory, reason almost forsook him. "My God, inspire me," he murmured. "How shall I save the honour of the name?"
