An expert historian on Mary, Queen of Scots draws on hundreds of her encrypted letters to paint a vivid portrait of one of history's most compelling figures. For almost two decades before her execution at Fotheringhay Castle in 1587, Mary, Queen of Scots was a prisoner. From her chambers, she wrote countless letters, many encrypted using complex ciphers to prevent her communications from being intercepted. In this way, she used language to exert her will and her influence, even while incarcerated. More than four hundred years after Mary's death, the discovery of further encoded letters has led to renewed interest in the breadth of her correspondence while in captivity. In Captive Queen: The Decrypted History of Mary, Queen of Scots, Jade Scott draws on hundreds of these ground-breaking letters to create a vivid picture of one of history's most fascinating personalities. She interprets Mary's complex relationships with friends and enemies alike throughout the years of her imprisonment, illuminating Mary's strategic vision while bringing her captivity to life like never before.
