Andrew Morton, author of Diana: Her True Story, turns his attention to Wallis Simpson, the twice-married divorcée who claimed the heart of Edward VIII, causing his abdication. Drawing on interviews, secret letters, diaries and previously unseen primary sources, Morton charts Wallis’s life, from falling in love with a female teacher as a teenager to ignoring the cries of her husband as he lay dying. While Morton makes plain Wallis’s disdain for the duke, it seems his devotion to her never wavered.
