"...a tall, graceful, well-formed girl, showing her high blood in every line of her face ...the Mellerbys had been Mellerbys from the time of King John, and had been living on the same spot for at least four centuries.... She was fair, with a somewhat thin, oval face, with dark eyes, and an almost perfect Grecian nose. Her mouth was small, and her chin delicately formed.... Her education had been as good as England could afford, and her intellect had been sufficient to enable her to make use of it"
