The Duke of Saint-Simon, memorialist (and Lauzun's brother-in-law)

The two brothers-in-law lived in Marly in a house where they shared a certain intimacy and Saint-Simon, according to what he says, had to ""extract from him [Lauzun] stories of the past"," among which most probably were those about the mysterious prisoner, based on his nocturnal conversations with Fouquet in Pignerol.At his death in 1754, Saint-Simon left a large number of manuscripts, which were not published due to an "Order of the King" to keep them secret in 1760.After full examination by two of the King's historiographers, a first edition of the "Memoirs" was issued in 1830.
