Every once in a while I make myself read a story that I am not comfortable with. This was one of them. Her mother dead, Salma goes to live with her father, choosing the attic room for her own. She begins to skip school to go to the cinema and see art house films. Here she meets Margot and the two begin a romance. The fourth character, the house, becomes jealous. This is a very sensual and strange story, but not so strange it lost me as often happens. The house is like a jealous male lover left behind by Salma's turn to Margot, and it eventually gets its revenge. This was one story in a collection called FEN, which Johnson published about five years ago. I will look for it. The stories all take place in East Anglia, a watery, boggy place, I believe. You could feel that in this story.
Here is a review from NPR of the collection.
