It’s the stuff of fiction. Ian McEwan’s mother had an affair with an army officer and became pregnant while her husband was away fighting in World War II. She ended up giving away the baby via a newspaper ad saying “Wanted, home for baby boy aged one month: complete surrender.” After her husband was killed in the war, however, she married the baby’s father and went on to have Ian, who didn’t know about his long lost brother until recently. According to an article in The Independent, McEwan’s brother David Sharp is turning the story into a book.
