The narrative centers on Suzanne, a violist in a string quartet, immediately following the death of her lover, Alex, a famous conductor, in a plane crash. The story explores Suzanne's grief, her struggle to maintain a semblance of normal life with her husband Ben, a composer, and her friend and quartet colleague Petra, and her anxieties about the affair being revealed, especially by Alex's widow, Olivia Elling.
