The protagonist of The Wife of Sir Isaac Harman is Lady Harman, née Ellen Sawbridge. The moral, emotional, and intellectual conflicts that this tall, sensitive, graceful woman confronts arise in the context of a loveless marriage with Sir Isaac Harman, a self-made man who has grown rich as the proprietor of International Bread and Cake Stores and Staminal Bread. Sir Isaac meets his future wife when she is only seventeen and still a student in a boardinghouse in Wimbledon; she marries him largely out of pity. But the marriage is not a happy one, despite great wealth and the birth of four children. Sir Isaac is inherently domineering, and in an age of Suffragettes he encounters a desire for greater freedom in his wife.
