In Morals of Marcus Ordeyne, we follow the life of Sir Marcus Ordeyne, a middle-aged bachelor and schoolmaster who enjoys the privileges of both wealth and title, allowing him a life of leisure. His world is turned upside down when he encounters a young girl in a London park, who has fled a Turkish harem only to find herself abandoned and destitute after her rescuers sudden death. With no clear path forward, Sir Marcus takes her into his home, leading to a series of unexpected and profound consequences. (Summary by Simon Evers)
