A slightly fictionalized account of life at Knole (Chevron in the novel) at the height of the Edwardian period. Probably her best novel.
The City of Florence, Historical Vistas and Personal Sightings, R.W.B.Lewis
I'm about halfway into this one. I don't know why I bought it - I've had a distaste for Florence ever since the Great Gelato Incident of 1998. Perhaps it's time to forgive and forget.
