Charles noticed it to Lady Harriet; and several of the visitors spoke of her this morning as a very pretty, lady-like, and graceful girl.  This was Thursday; on Friday, as Lady Harriet had told her, some visitors from the more immediate neighbourhood were expected to stay over the Sunday:  but she had not mentioned their names, and when Molly went down into the drawing-room before dinner, she was almost startled by perceiving Roger Hamley in the centre of a group of gentlemen, who were all talking together eagerly, and, as it seemed to her, making him the object of their attention.  He made a hitch in his conversation, lost the precise meaning of a question addressed to him, answered it rather hastily, and made his way to where Molly was sitting, a little behind Lady Harriet.  He had heard that she was staying at the Towers, but he was almost as much surprised as she was by his unexpected appearance, for he had only seen her once or twice since his return from Africa, and then in the guise of an invalid.  Now in her pretty evening dress, with her hair beautifully dressed, her delicate complexion flushed a little with timidity, yet her movements and manners bespeaking quiet ease, Roger hardly recognized her, although he acknowledged her identity.  He began to feel that admiring deference which most young men experience when conversing with a very pretty girl:  a sort of desire to obtain her good opinion in a manner very different to his old familiar friendliness.  He was annoyed when Sir Charles, whose especial charge she still was, came up to take her in to dinner.  He could not quite understand the smile of mutual intelligence that passed between the two, each being aware of Lady Harriet’s plan of sheltering Molly from the necessity of talking, and acting in conformity with her wishes as much as with their own.  Roger found himself puzzling, and watching them from time to time during dinner.  Again in the evening he sought her out, but found her again preoccupied with one of the young men staying in the house, who had had the advantage of two days of mutual interest, and acquaintance with the daily events and jokes and anxieties of the family-circle.  Molly could not help wishing to break off all this trivial talk and to make room for Roger:  she had so much to ask him about everything at the Hall; he was, and had been such a stranger to them all for these last two months, and more.  But though each wanted to speak to the other more than to any one else in the room, it so happened that everything seemed to conspire to prevent it.  Lord Hollingford carried off Roger to the cluster of middle-aged men; he was wanted to give his opinion upon some scientific subject.  Mr. Ernulphus Watson, the young man referred to above, kept his place by Molly, as the prettiest girl in the room, and almost dazed her by his never-ceasing flow of clever small-talk.  She looked so tired and pale at last that the ever-watchful Lady Harriet sent Sir Charles to the rescue, and after a few words with Lady Harriet, Roger saw Molly quietly leave the room; and a sentence or two which he heard Lady Harriet address to her cousin made him know that it was for the night.  Those sentences might bear another interpretation to the obvious one.
