Imprisoned for nearly 20 years by her cousin Queen Elizabeth I, Mary, Queen of Scots, fought her battles through words, sending and receiving coded letters hidden in books, garments, and even beer barrels. Historian Jade Scott, of the University of Glasgow, Scotland, has uncovered the human and political depths behind Mary’s captivity through 57 recently decrypted letters, coded missives that reveal her as a strategist, an adept diplomat, and a woman navigating the perilous politics of Elizabethan England. In her new book, Captive Queen: The Decrypted History of Mary, Queen of Scots, Scott draws on these newly decoded letters to illuminate Mary’s time in captivity, her alliances and betrayals, and the intricate game of espionage that ultimately led to her execution.
