A man came in, and it was a fresh surprise for Marius, as the man he now saw was a perfect stranger to him. This man, who was old, by the way, had a large nose, his chin in his cravat, green spectacles, with a double shade of green silk over his eyes, and his hair smoothed down and flattened on his forehead over his eyebrows, like the wig of English coachmen of high life. His hair was gray. He was dressed in black from head to foot,--a very seedy but clean black,--and a bunch of seals, emerging from his fob, led to the supposition that he had a watch. He held an old hat in his hand, and walked bent, and the curve in his back augmented the depth of his bow. The thing which struck most at the first glance was that this person's coat, too large, though carefully buttoned, had not been made for him. A short digression is necessary here. There was at that period in Paris, in an old house situated in the Rue Beautreillis near the arsenal, an old Jew whose trade it was to convert a rogue into an honest man, though not for too long a period, as it might have been troublesome to the rogue. The change was effected at sight, for one day or two, at the rate of thirty sous a day, by means of a costume resembling as closely as possible every-day honesty. This letter-out of suits was called the "exchange-broker." Parisian thieves had given him that name, and knew him by no other. He had a very complete wardrobe, and the clothes in which he invested people suited almost every condition. He had specialties and categories: from each nail of his store hung a social station, worn and threadbare; here the magistrate's coat, there the curé's coat, and the banker's coat; in one corner the coat of an officer on half pay, elsewhere the coat of a man of letters, and further on the statesman's coat. This creature was the costumer of the immense drama which roguery plays in Paris, and his den was the side-scene from which robbery went out or swindling re-entered. A ragged rogue arrived at this wardrobe, deposited thirty sous, and selected, according to the part which he wished to play on that day, the clothes which suited him; and, on going down the stairs again, the rogue was somebody. The next day the clothes were faithfully brought back, and the "exchange-broker," who entirely trusted to the thieves, was never robbed. These garments had one inconvenience,--they did not fit; not being made for the man who wore them, they were tight on one, loose on another, and fitted nobody. Any swindler who exceeded the average mean in height or shortness was uncomfortable in the "exchange-broker's" suits. A man must be neither too stout nor too thin, for the broker had only provided for ordinary mortals, and had taken the measure of the species in the person of the first thief who turned up, and is neither stout nor thin, nor tall nor short. Hence arose at times difficult adaptations, which the broker's customers got over as best they could. All the worse for the exceptions! The
