Camilla focuses on the story of the Tyrold family. Augustus ("Mr Tyrold") and Sir Hugh Tyrold are brothers who, after a period of estrangement lasting an unspecified number of years, are reunited after Sir Hugh sends Mr Tyrold a letter expressing his desire to move near his parsonage, requesting him to purchase an estate called Cleves and prepare it for the arrival of Sir Hugh, his niece Indiana Lynmere, and her governess Miss Margland (his other ward, Clermont Lynmere, is to be sent to "the Continent" to be educated). His primary motivation for the move is that after years of being active, and a confirmed bachelor, he is injured and becomes too weak to partake of the active physical and social life he once enjoyed.
