Grania and Sylvia Fox live in the Georgian house of Aragon, with their mother, their Aunt Pidgie and Nan O'Neill, the family nurse. Grania is conducting a secret affair with Nan's son, Foley, a wily horse-breeder, whilst Sylvia who is 'pretty in the right and accepted way' falls for the charms of Captain Purvis. Attending Aragon's strawberry teas, the British Army Officers can almost forget the reason for their presence in Ireland. But the days of dignified calm at Aragon are numbered, for Foley is a member of Sinn Fein.
