start of the volume, Steinmetz introduces the concept of "chevaliers d'industrie," or polite sharpers, detailing their methods of manipulation and deceit. The opening chapters recount the rise of these skilled con artists, illustrating their gradual encroachment upon the innocent, often by involving them in gambling schemes laced with treachery. One highlighted character, Olivier, a young man from a respectable family, falls prey to the persuasive tactics of a card-sharper named Chauvignac, leading him into a series of gambling exploits that culminate in ruin. The opening sets the stage for a historical examination of how gambling not only ensnares individuals but can also perpetuate cycles of despair, violence, and social decay.
