All Men are Mortal. Translated by Leonard M. Friedman. New York: W. W. Norton & Co., 1992. English translation of Tous les Hommes sont Mortels (Paris: Gallimard, 1946).
From the publisher:
Probably de Beauvoir’s strangest and most compelling novel, this is the captivating story of a beautiful young actress who revives a downcast stranger at a French resort. He becomes thoroughly attached to her and confides a terrifying truth: he is immortal. But having been resuscitated into enjoying life again, he soon starts breaking free from her grasp and all notions of mortality.
