After nine years, Hannah Setterington has decided to sell the Distinguished Academy of Governesses and explore the secrets of her past. To that end she has agreed to be a companion to the elderly aunt of Lord Raeburn, a man enshrouded by dark mystery and haunted by the rumor that he murdered his wife. A strong-minded woman accustomed to the vagaries of nobility, Hannah believes the rumor to be so much piffle, until she comes face to face with Lord Raeburn.
