"What was strange to Susan was that she felt nothing. She could think sad thoughts, because in the circumstances they had to be sad. She knew who was in the coach. But it had already happened. There was nothing she could do to stop it, because if she'd stopped it, it wouldn't have happened. And she was here watching it happen. So she hadn't. So it had. She felt the logic of the situation dropping into place like a series of huge leaden slabs. (p. 301)"
