In 1894, Alfred Dreyfus, a Jewish officer in the French army, was wrongfully convicted of being a spy for Germany and was imprisoned on Devil's Island. Oxford historian Ruth Harris presents the scandal of the century in all its human complexity. Drawing on private letters and thousands of previously unconsidered sources, Harris offers a definitive account of the tragic drama that divided French society and stunned the world. Sweeping and engaging, Harris's retelling of the Dreyfus Affair extricates it from the myths of both the left and the right, offering a new understanding of one of the most significant episodes in modern history.
