On Green Dolphin Street by Sebastian Faulks
Mary Van der Linden is a pretty, reserved, Englishwoman whose husband, Charlie, is posted to the British embassy in Washington. One night at a cocktail party Mary meets Frank Renzo, a reporter who has covered stories from the fall of Dienbienphu to the Emmett Till murder trial in Mississippi. Slowly, reluctantly, they fall in love. Their ensuing affair, in all its desperate elation, plays out against a backdrop that ranges from the jazz clubs of Greenwich Village to the smoke-filled rooms of the Kennedy campaign.
