Orley Farm by Anthony Trollope

Lady Mason on her return from London found a note from Mrs. Orme asking both her and her son to dine at The Cleeve on the following day. As it had been already settled between her and Sir Peregrine that Lucius should dine there in order that he might be talked to respecting his mania for guano, the invitation could not be refused; but, as for Lady Mason herself, she would much have preferred to remain at home.

Indeed, her uneasiness on that guano matter had been so outweighed by worse uneasiness from another source, that she had become, if not indifferent, at any rate tranquil on the subject. It might be well that Sir Peregrine should preach his sermon, and well that Lucius should hear it; but for herself it would, she thought, have been more comfortable for her to eat her dinner alone. She felt, however, that she could not do so. Any amount of tedium would be better than the danger of offering a slight to Sir Peregrine, and therefore she wrote a pretty little note to say that both of them would be at The Cleeve at seven.
