The Heart Is a Burial Ground

On a brisk day in 1970, a daughter arrives at her mother's home to take care of her as she nears the end of her life. 'Home' is the sprawling Italian castle of Roccasinibalda, and Diana's mother is the legendary Caresse Crosby, one half of literature's most scandalous couple in 1920s Paris, widow of Harry Crosby, the American heir, poet and publisher who epitomised the 'Lost Generation'.
