Rosemary Sutcliff tells her own story, about her life until her first books were published, and she started writing a diary, in Blue Remembered Hills—A Recollection. It has been most recently republished by Slightly Foxed. It was first published in 1983 by The Bodley Head.
Rosemary Sutcliff talks about herself and her writing—the only recorded interview with her that I have heard— in an interview on BBC Radio with Roy Plomley for an edition of the long-running, classic radio programme Desert Island Discs, also in 1983. Roy Plomley had presumably read her memoir.
When anybody asks me where I was born, or when I am called on to provide that information in filling out a form, I admit with a distinct sense of apology that I was born in Surrey.
