The rooms reserved for the travellers on the first floor were three in number; consisting of two bedrooms opening into each other, and communicating on the left with a drawing-room.  Complete so far, the arrangements proved to be less satisfactory in reference to the third bedroom required for Agnes and for the eldest daughter of Lord Montbarry, who usually slept with her on their travels.  The bed-chamber on the right of the drawing-room was already occupied by an English widow lady.  Other bedchambers at the other end of the corridor were also let in every case.  There was accordingly no alternative but to place at the disposal of Agnes a comfortable room on the second floor.  Lady Montbarry vainly complained of this separation of one of the members of her travelling party from the rest.  The housekeeper politely hinted that it was impossible for her to ask other travellers to give up their rooms.  She could only express her regret, and assure Miss Lockwood that her bed-chamber on the second floor was one of the best rooms in that part of the hotel.

On the retirement of the housekeeper, Lady Montbarry noticed that Agnes had seated herself apart, feeling apparently no interest in the question of the bedrooms.  Was she ill?  No; she felt a little unnerved by the railway journey, and that was all.  Hearing this, Lord Montbarry proposed that she should go out with him, and try the experiment of half an hour’s walk in the cool evening air.  Agnes gladly accepted the suggestion.  They directed their steps towards the square of St. Mark, so as to enjoy the breeze blowing over the lagoon.  It was the first visit of Agnes to Venice.  The fascination of the wonderful city of the waters exerted its full influence over her sensitive nature.  The proposed half-hour of the walk had passed away, and was fast expanding to half an hour more, before Lord Montbarry could persuade his companion to remember that dinner was waiting for them.  As they returned, passing under the colonnade, neither of them noticed a lady in deep mourning, loitering in the open space of the square.  She started as she recognised Agnes walking with the new Lord Montbarry—­ hesitated for a moment—­and then followed them, at a discreet distance, back to the hotel.

Lady Montbarry received Agnes in high spirits—­with news of an event which had happened in her absence.

She had not left the hotel more than ten minutes, before a little note in pencil was brought to Lady Montbarry by the housekeeper.  The writer proved to be no less a person than the widow lady who occupied the room on the other side of the drawing-room, which her ladyship had vainly hoped to secure for Agnes.  Writing under the name of Mrs. James, the polite widow explained that she had heard from the housekeeper of the disappointment experienced by Lady Montbarry in the matter of the rooms.  Mrs. James was quite alone; and as long as her bed-chamber was airy and comfortable, it mattered nothing to her whether she slept on the first or the second floor of the house.  She had accordingly much pleasure in proposing to change rooms with Miss Lockwood.  Her luggage had already been removed, and Miss Lockwood had only to take possession of the room (Number 13 A), which was now entirely at her disposal.
