The Sexual Life of Catherine M. was Catherine Millet's diary of sexual encounters and explorations. But one day she discovered a letter from which it became clear that her partner was involved elsewhere. Jealousy (Serpent's Tail, 2009) details the crisis provoked by this discovery and her reaction to it. Jealousy is the paradoxical confession of a libertine, who succumbs to the 'timeless and universal malady'. Catherine Millet is art critic, curator, and founder and editor of the prestigious magazine Art Press.
