"Johnson did not hit Jill as hard as he used to hit his wife before she left him, not nearly as hard as he hit prisoners who were reluctant to talk. Until then Smith had shown no expression and had said nothing; he had simply let himself be forced along. He had understood none of it and had tried to do nothing at all. When he saw his water brother struck by this other, he twisted, got free — and reached toward Johnson — — and Johnson was gone. Only blades of grass, straightening up where his big feet had been, showed that he had ever been there. Jill stared at the spot and felt that she might faint."
