Born in idyllic Devonshire and earning a PhD in economics, heiress Rose Dugdale was an improbable candidate for joining the Irish Republican cause. But as Anthony Amore recounts here, Dugdale perpetrated the first aerial terrorist attack in British history and pulled off the biggest art theft of her time: In 1974, she led a gang into the Russborough House and made off with millions in prized paintings, including a masterpiece by Johannes Vermeer. With astonishment and a measure of respect, Amore tells the story of this lifelong radical.
