Catherine's ups and downs were part of Nick's mythology of the house. Toby had told him about them, as a mark of trust, one evening in college, sitting on a bench by the lake. "She's pretty volatile, you know," he said, quietly impressed by his own choice of word. "Yah, she has these moods." To Nick the whole house, as yet only imagined, took on the light and shade of moods, the life that was lived there as steeped in emotion as the Oxford air was with the smell of the lake water. "She used to, you know, cut her arms, with a razor blade." Toby winced and nodded. "Thank god she's grown out of all that now." This sounded more challenging than mere moods, and when Nick first met her he found himself glancing tensely at her arms. On one forearm there were neat parallel lines, a couple of inches long, and on the other a pattern of right-angled scars that you couldn't help trying to read as letters; it might have been an attempt at the word ELLE. But they were long healed over, evidence of something that would otherwise be forgotten; sometimes she traced them abstractedly with a finger.

"Looking after the Cat" was how Gerald had put it before they went away, with the suggestion that the task was as simple as that, and as responsible. It was Catherine's house but it was Nick who was in charge. She camped nervously in the place, as though she and not Nick was the lodger. She was puzzled by his love of its pompous spaces, and mocked his knowledgeable attachment to the paintings and furniture. "You're such a snob," she said, with a provoking laugh; coming from the family he was thought to be snobbish about, this was a bit of a facer.
