A collection of long-lost letters dating from 1928 recently discovered in a dusty cellar in Paris paint a vivid portrait of a passionate love affair between a woman – identified only as Simone – and her married lover, Charles. As their relationship evolves in sometimes shocking and unexpected ways, Simone lays bare her desires, fears, anxieties and fantasies as she is driven to increasing lengths to gain satisfaction.Framed by illuminating insights from the man who found and edited them, these letters open a window into another time and another life, and a woman whose voice echoes down the century and still resonates today.
