Correspondence begins with McPhee and FitzGerald's thanks to Fiona for meeting them at the Fawcett Library in May 1983. They explain their plans to write an analysis of Teresa Billington-Greig's published work alongside her biography. Correspondence becomes increasingly personal, charting the growing friendship of Fiona, McPhee and FitzGerald as they arrange personal as well as business-related trips. Letters discuss family, friends and pets. They exchange newspaper and magazine subscriptions, Fiona receiving first The New Yorker and then Gourmet magazine, McPhee and FitzGerald receiving the Guardian newspaper. They discuss current affairs and American politics in great depth over the years, especially the American elections and ongoing abortion protests by anti-choice groups outside planned parenthood clinics.
