A young woman returns to an empty London house after an impulsive Alpine adventure with a younger man; she relives their mistaken detour to a mountain inn, the prolonged shared days that became intimacy, and the uneasy shift back to routine. The narrative moves between vivid travel episodes and domestic stillness, tracing her practical control during the journey, the admiration that accompanied their companionship, and her deliberate preservation of the experience as memory. Themes include the tension between desire and duty, the shaping of identity by fleeting romance, and social expectations around age and womanhood.
