Twenty minutes afterwards a carriage stopped at the house, a lady alighted in a black or dark blue dress, and always thickly veiled; she passed like a shadow through the lodge, and ran upstairs without a sound escaping under the touch of her light foot. No one ever asked her where she was going. Her face, therefore, like that of the gentleman, was perfectly unknown to the two concierges, who were perhaps unequalled throughout the capital for discretion. We need not say she stopped at the first floor. Then she tapped in a peculiar manner at a door, which after being opened to admit her was again fastened, and curiosity penetrated no farther. They used the same precautions in leaving as in entering the house. The lady always left first, and as soon as she had stepped into her carriage, it drove away, sometimes towards the right hand, sometimes to the left; then about twenty minutes afterwards the gentleman would also leave, buried in his cravat or concealed by his handkerchief.
