Monsieur Monde is a successful middle-aged businessman in Paris. One morning he walks out on his life, leaving his wife asleep in bed, leaving everything.

Not long after, he surfaces on the Riviera, keeping company with drunks, whores and pimps, with thieves and their marks. A whole new world, where he feels surprisingly at home--at least for a while.

Georges Simenon knew how obsession, buried for years, can come to life, and about the wreckage it leaves behind. He had a remarkable understanding of how bizarrely unaccountable people can be. And he had an almost uncanny ability to capture the look and feel of a given place and time. Monsieur Monde Vanishes is a subtle and profoundly disturbing triumph by the most popular of the twentieth century's great writers.
