In the Rue de Mesrominil there was a little _brasserie_, or public-house, much frequented by servants of the upper class. This place was owned by a man named Edouard Morant, whose daughter, a girl of eighteen, had been the sweetheart of Henri Dessaure, the absconding footman. This girl, learning that Dessaure had been false to her, made it her business to find out who had supplanted her in the affections of her sweetheart, and discovered that Dessaure had been seen very often in the company of a dancing-girl from the Bal Boullier, and also that this girl had left Paris only a few days ago, having purchased a second-class ticket to New York. She further ascertained that the girl had been somewhat in debt, but that shortly before leaving she had discharged her obligations, and also purchased a large amount of clothes and finery. All this the jealous Mlle. Morant told M. Brissard. It was now Saturday, and the dancing-girl had sailed for America on Wednesday. M. Brissard at once communicated with the American police, and when the French Line steamer _La Touraine_ arrived at New York a certain young lady, a second-cabin passenger, was closely followed when she left the ship. No one was at the docks to meet her, but after her luggage had passed the Customs inspection she engaged an express wagon to convey her trunks and bags to an address in First Avenue, near Twelfth Street, giving the address to the driver from a card on which it had been written, no doubt for her guidance. One detective followed the luggage, while a second kept his eye on the girl. Calling a cab, she again showed the card and was driven off, followed by Officer O'Brien, whose colleague, Kernohan, remained with the express wagon. Arrived at her destination, the girl, looking up to make sure of the number, ascended the stairs of a four-storey brick building, the ground floor of which was occupied by a small French restaurant. The cab waited, and shortly a young man came down, who proceeded to pay the driver. The young man exactly answered the description sent over from Paris of the missing Henri Dessaure! After paying the cab fare he returned into the house, while Officer O'Brien called a policeman and instructed him to telephone to head-quarters. So it happened that just about the time Detective Kernohan appeared with the express-man, a third detective arrived on the scene with a provisional warrant, granted by the magistrate at Jefferson Market police-court, for the arrest of Dessaure on suspicion of being a fugitive from justice. The express-man proceeded to unload his wagon, having first rung the door-bell, and once again the young man who bore so striking a resemblance to the Baroness de Martigny's late valet came to the door. This time he was confronted by two officers, who promptly informed him that he was under arrest. "We believe you to be Henri Dessaure, late of Paris," said Detective O'Brien.
