Charlotte Philby's latest novel tells the story of her grandfather, Kim Philby, the notorious double-agent in the Cambridge spy ring. Edith and Kim is her fourth novel, and tells the linked stories of her grandfather and Edith Tudor-Hart, the Vienna-born photographer and Communist agent who recommended Kim Philby for recruitment by the KGB. Charlotte Philby's father was a child when her grandfather defected. He tracked him down in Moscow years later, and as a five year old, Charlotte went on a family visit to Kim in Russia. She says initially she didn't want to write about Kim Philby because she didn't want to define herself through his life. But after years of having other people project versions of her grandfather, the time has come to reclaim the story.
