Lovesey, P: Rough Cider

The standalone novel from the critically-acclaimed Peter Lovesey. Rough Cider was nominated for an Edgar Award.
It is World War II and American soldiers stationed in rural England have made friends, especially with the local girls. After a dance to celebrate the pressing of the apples into cider, the resentment of the local men leads to violence and a murder. Later, a baby girl is born.
Years later, Theo, a university lecturer, is approached by an American girl called Alice. She wants to be told about her father, a GI hanged for murder in Somerset during World War II. As a boy, Theo had been a principal witness for the prosecution.
Alice persuades him to revisit the farm where Theo was evacuated, staunchly determined to discover the facts. The horrors of the past take on a frightening immediacy when long-forgotten jealousies come to the surface and another murder is committed.
