Read it through once

“I didn’t invite her, and when we came back from London I didn’t know she was here. No one invited her. She’s a friend of my mother’s, and just after you and I went to town my mother got a note from her. She had arrived in England (she usually lives abroad, though she has first and last spent a good deal of time here), and asked leave to come down for a few days. She’s a woman who can make such proposals with perfect confidence; she’s so welcome wherever she goes. And with my mother there could be no question of hesitating; she’s the one person in the world whom my mother very much admires. If she were not herself (which she after all much prefers), she would like to be Madame Merle. It would indeed be a great change.”
