The Bahamas, 1941. Newly-widowed Leonora 'Lulu' Randolph arrives in Nassau to investigate the Governor and his wife for a New York society magazine. But as she infiltrates the Duke and Duchess's social circle, and the powerful cabal that controls the islands' political and financial affairs, she uncovers evidence that beneath the glitter of Wallis and Edward's marriage lies an ugly, and even treasonous, reality. Windsor-era Nassau seethes with spies, financial swindles, and racial tension, and in the middle of it all stands Benedict Thorpe: a scientist of tremendous charm and murky national loyalties. Inevitably, the willful and wounded Lulu falls in love. Then Nassau's wealthiest man is murdered in one of the most notorious cases of the century, and the resulting coverup reeks of royal privilege. Benedict Thorpe disappears without a trace, and Lulu embarks on a journey to London and beyond to unpick Thorpe's complicated family history.
