When Catherine woke and turned the light on, she was shaking, her whole body was cold. This, she thought, is aftershock. She had been fine all afternoon: a little sleepy, but fine. Now she was trembling. Her feet were freezing.

She put on a cardigan, found warm socks and turned the central heating on. It was still dark and too early to let the dogs out. She made coffee, stronger than usual, and sat at the kitchen table without putting on the main light. She liked this time of day. If the tide was coming in, the air was salty and fresh, and you could watch daylight starting out on the water past the rocks.
