Six years that changed the monarchy
The book follows the crisis in order, from the first meeting to the wedding no royal attended, and stops at each point where things could have gone differently.
The Prince of Wales meets Wallis Simpson, an American married to her second husband, at a country house party.
His 16-year relationship with Freda Dudley Ward ends, and Wallis becomes the centre of his life.
George V dies. Edward becomes King, and his courtiers start to worry about what comes next.
After weeks of pressure from the government and the palace, Edward signs the Instrument of Abdication.
He tells the nation by radio that he cannot carry on "without the help and support of the woman I love".
Edward and Wallis marry in France. Not one member of the royal family attends.
