Mabel grew up motherless in a country house full of roses, preferring her garden to London's gloomy social round, and never learned that her father had been watching her admirers with anxious suspicion. She carries one buried sorrow — a brother banished from Oxford and sent abroad, whose whereabouts her father refused to reveal. When Collins arrives to tell her Sir James is dead, her stunned, uncomprehending grief opens the novel's emotional register and ties her fate to the mystery's heart.
