11 December 1936. The King of England, Edward VIII, has given up his crown, foregoing his duty for the love of Wallis Simpson, an American divorcée. Their courtship has been dogged by controversy and scandal, but with Edward’s abdication, they can live happily ever after.

But do they? Beginning this astonishing dual biography at the moment that most biographers turn away, bestselling historian Andrew Lownie reveals the dramatic lives of the Windsors post-abdication. This is a story of a royal shut out by his family and forced into exile; of the Nazi attempts to recruit the duke to their cause; and of why the duke, as Governor of the Bahamas, tried to shut down the investigation into the murder of a close friend. It is a story of a couple obsessed with their status, financially exploiting their position, all the while manipulating the media to portray themselves as victims.

The Duke and Duchess of Windsor were, in their day, the most glamorous exiles in the world, flitting from sumptuously appointed mansions in the south of France to luxurious residences in Palm Beach. But they were spoiled, selfish people, obsessed with their image, and revelling in adulterous affairs. Drawing upon previously unexplored archives, Lownie shows in dramatic fashion how their glittering world was riddled with treachery and betrayal—and why the royal family never forgave the duke for choosing love over duty.
