Elizabeth von Arnim's novel tells the story of four dissimilar women in 1920s England who leave their damp and rainy environs to go on a holiday to a secluded coastal castle in Italy. Mrs Arbuthnot and Mrs Wilkins, who belong to the same ladies' club but have never spoken, become acquainted after reading a newspaper advertisement for a 'small mediaeval Italian castle on the shores of the Mediterranean to be let furnished for the month of April'.
