A literary treasure: the recently discovered letters that chronicle the passionate affair of a young woman in Paris in 1928. The Passion of Mademoiselle S. is a tour de force. In language that is by turns elegant, impassioned, and surprisingly graphic, these love letters are a portrait of a sexual and psychological obsession. Berthault’s notes on the period add dimension and context to the correspondence. But it is the voice of Simone—that of a sensual, vulnerable, and curiously modern woman—that comes through most vibrantly and echoes down the centuries.
