The diaries began in 1930 when my mother Anne was 15 and living in Sussex, and conjured up a world of hunt balls, tennis parties and upmarket travel through France and Italy. A few teenage ‘crushes’ were described — she fixated on one Lady Ann Cole, with green eyes and a green fan, after a dance in January; then in the same year, in August, on Brioni (now Brijuni), an island off Croatia, there was American Mary, ‘delicate and faun-like’. In spring 1932, my mother, 17, while staying at the Hôtel Imperial in Paris, romanced about a young widowed Italian contessa.
