Quote from : Quartet Book

She spent the foggy day in endless, aimless walking, for it seemed to her that if she moved quickly enough she would escape the fear that hunted her. It was a vague and shadowy fear of something cruel and stupid that had caught her and would never let her go. She had always known that it was there - hidden under the more of less pleasant surface of things. Always. Ever since she was a child. You could argue about hunger or cold or loneliness, but with that fear you couldn't argue. It went too deep. You were too mysteriously sure of its terror. You could only walk very fast and try to leave it behind you.
