Mrs. Boynton is sadistic and domineering, behaviours which she may have carried over from her original profession of prison warden. Sarah is attracted to Raymond Boynton, while Jefferson Cope admits to wanting to take Nadine Boynton away from her husband, Lennox Boynton, and the influence of her mother-in-law. Having been thwarted in her desire to free the young Boyntons, Sarah confronts Mrs. Boynton whose apparent reply is a strange threat: "I’ve never forgotten anything – not an action, not a name, not a face." When the party reaches Petra, Mrs. Boynton uncharacteristically sends her family away from her for a period. Later, she is found dead with a needle puncture in her wrist.
