The photograph has fixed the three figures forever, two men and a woman bathed in bright sunshine. Parisian archivist Helene takes out a newspaper advert calling for information about her mother, who died when she was three, and the two men pictured with her in a photograph taken at a tennis tournament at Interlaken in 1971. Stephane, a Swiss biologist living in Kent, responds: his father is one of the people in the photo. More letters and more photos pass between them as they embark on a journey to uncover the truth their parents kept from them. But will the images and documents from the past fill the silences left by the players? Winner of fifteen literary awards, this dark yet touching drama deftly explores the themes of blame and forgiveness, identity and love.
