Céleste Albaret was Marcel Proust's governess and confidante for the last eight years of his life. Between them, a unique complicity and friendship have been forged, a mutual fascination. At the end of her life, Céleste delivered her memories to Georges Belmont. She recounts the shared daily life, the sleepless days and nights, the relentless writing of Research. Marianne Denicourt has extracted from this fascinating and major testimony the essential moments of the life of M. Proust and delivers them to us with an accuracy of interpretation which immerses us in the intimate life of Marcel.
