One summer in the sixties, in a staid suburb south of London, nineteen-year-old Paul comes home from university and is urged by his mother to join the tennis club. There he’s partnered with Susan Macleod, a fine player who’s forty-eight, confident, witty, and married, with two nearly adult daughters. She is a warm companion, her bond with Paul immediate. And soon, inevitably, they are lovers.

Basking in the glow of one another, they set up house together in London. Decades later, Paul looks back at how they fell in love and how—gradually, relentlessly—everything fell apart. As he turns over his only story in his mind, examining it from different vantage points, he finds himself confronted with the contradictions and slips of his own memory—and the ways in which our narratives and our lives shape one another.
