'It is rather awful, Emma thought as she walked across the fields down to the farm, how this business is leading us all into subterfuge and deception, and we can't really tell who is friend and who is enemy . . . '

Emma wakes up one morning to an apocalyptic world. The cosy existence she shares with her grandmother, a famous retired actress, has been shattered: there's no post, no telephone, no radio - and an American warship sits in the harbour. As the two women piece together clues about the 'friendly' military occupation on their doorstep, family, friends and neighbours gather round to protect their heritage. In this chilling novel of the future, Daphne du Maurier explores the implications of a political, economic and military alliance between Britain and the United States.
