Originally published in 1869, this surprisingly modern story explores the relationships between three men, one old and very rich, two young and very poor. After returning from a prolonged period in Europe, Maximus Austin joins his friend Theodore Lisle at the luxurious estate of Frederick Sloane, who has hired Theodore as his secretary. It quickly becomes clear that Sloane's affections are fickle and that his fortune is up for grabs. But what exactly are the motivations of the two young men? Is one of them really more virtuous than the other? And who, exactly, is the 'light man' that the title refers to? Henry James keeps us guessing, right up to the end of the story. This early work displays James' intense ability to illuminate the psychology behind human behavior.
