Rachel Field's novel is based on the true story of Field's great-aunt, Henriette Deluzy-Desportes, a French governess who fell in love with the Duc de Praslin, her employer. When Praslin's wife was murdered, Henriette was implicated. It was a real-life scandal that contributed to the political turmoil before the French Revolution of 1848 which deposed France's Louis Philippe I.| Wikipedia|
