[The Edwardian era] was a time of booming trade, of great prosperity and wealth in which the pageant of London Society took place year after year in a setting of traditional dignity and beauty. The great houses—Devonshire, Dorchester, Grosvenor, Stafford and Lansdowne House—had not yet been converted into museums, hotels and flats, and there we danced through the long summer nights till dawn. The great country-houses still flourished in their glory, and on their lawns in the green shade of trees the art of human intercourse was exquisitely practised by men and women not yet enslaved by household cares and chores who still had time to read, to talk, to listen and to think.
