The Adulterous Woman by Albert Camus

A middle-aged woman married to a practical, unimaginative man grows acutely aware of the emptiness of her domestic life while on a business trip; wandering alone one night she climbs to a hill overlooking the distant city and is seized by an intense, fleeting sense of possibility and desire that seems to offer an escape from boredom and isolation, yet when she returns to her husband the promise dissolves into the familiar resignation, leaving her to confront the painful gap between longing and action and the existential solitude at the heart of her marriage.
