The Slaves of Paris by Emile Gaboriau

The Marquis de Croisenois lived in a fine new house on the Boulevard Malesherbes near the church of St. Augustine, and in a suite of rooms the rental of which was four thousand francs per annum. He had collected together sufficient relics of his former splendor to dazzle the eyes of the superficial observer. The apartment and the furniture stood in the name of his body-servant, while his horse and brougham were by the same fiction supposed to be the property of his coachman, for even in the midst of his ruin the Marquis de Croisenois could not go on foot like common people.

The Marquis had two servants only in his modest establishment -- a coachman, who did a certain amount of indoor work, and a valet, who knew enough of cookery to prepare a bachelor breakfast. This valet Mascarin had seen once, and the man had then produced so unpleasant an impression on the astute proprietor of the Servants' Registry Office that he had set every means at work to discover who he was and from whence he came. Croisenois said that he had taken him into his service on the recommendation of an English baronet of his acquaintance, a certain Sir Richard Wakefield. The man was a Frenchman, but he had resided for some time in England, for he spoke that language with tolerable fluency. André knew nothing of these details, but he had heard of the existence of the valet from M. de Breulh, when he had asked where the Marquis lived.
