The story begins in August 1939, when young adults Oliver, Calypso, Polly, and Polly's brother Walter are visiting their disorganised Aunt Helena and her husband Richard Cuthbertson at their house by the sea in
Cornwall, which has a
camomile lawn. Ten-year-old Sophy, the daughter of Richard’s late half-sister, lives with them and is delighted with the arrival of her cousins, especially Oliver. The family is often visited by the twin sons of the rector of the parish and by Max and Monika Erstweiler, a Jewish refugee couple from
Austria whom the rector has taken in; they are missing their only son, Pauli, reported to be in a German
concentration camp. The cousins invent 'The Terror Run', a cliff path dash which they race at night by the light of a full moon. They are joined by some of the adults, and Sophy is determined to run it as well. However, on a daylight practice run, a
coastguard exposes himself to Sophy, with surprising results. After he has fought in the
Spanish Civil War, Oliver is depressed and disenchanted, but develops a crush on Calypso. She fends him off, determined to make the most of her beauty and marry a much richer man. Polly is intelligent and practical, and when the
Second World War breaks out in September 1939 she joins the
War Office to work for
Military intelligence, while her brother Walter joins the
Royal Navy, Oliver the army, and the twins the Royal Air Force. Meanwhile, Max and Monika are
interned as enemy aliens. Calypso marries Hector Grant, a Scottish landowner and member of parliament, but has many affairs. The Erstweilers are released, and Helena begins an affair with Max, and Richard with Monika. Walter is killed at sea, and Calypso has a son, Hamish, shortly after her London house has been hit by a bomb, with Sophy acting as midwife. Pauli Erstweiler is reported to have died in Dachau, but in fact survived the war. In 1984, more than forty years later, the survivors meet again at the house in Cornwall for the funeral of Max Erstweiler. He had become a well-known violinist and bought the house from Helena after Richard’s death. Oliver is now a well-known author. Oliver says he has had two failed marriages to Calypso lookalikes. He and Sophy find they are both single and leave the funeral together, planning to get to know each other. The house now belongs to Pauli, who plans to replace the camomile lawn with a swimming pool and sell the property. ==Cast==
