David Kepesh is white-haired and over sixty, an eminent TV culture critic and star lecturer at a New York college, when he meets Consuela Castillo, a decorous, well-mannered student of twenty-four, the daughter of wealthy Cuban exiles, who promptly puts his life into erotic disorder. Since the sexual revolution of the 1960s, when he left his wife and child, Kepesh has experimented with living what he calls an `emancipated manhood`, beyond the reach of family or a mate. Over the years, he has refined that exuberant decade of protest and licence into an orderly way of life in which he is both unimpeded in the world of Eros and studiously devoted to his aesthetic purists. But the youth and beauty of Consuela undo him completely. His worldliness, his confidence, his reason desert him, and a maddening sexual possessiveness transports him to the depths of deforming jealousy.
