Write about what you know, as creative writing students are always told. So Graham Greene did just that when he wove the story of his 13-year adulterous relationship with Catherine Walston into his 1951 novel The End Of The Affair. Son Oliver finds it all very fascinating, while daughter Anne is coldly disapproving of her mother's involvement with someone she regarded as selfish and demanding. Greene didn't help matters by naming his fictional cuckolded husband Henry; Walston Snr was called Harry.
