Calder Walton is one of the world's leading intelligence historians. He is editor-in-chief of the Cambridge History of Espionage and Intelligence, to be published by Cambridge University Press in three volumes, which will be a landmark study in the global history of intelligence. Currently the Assistant-Director of the Applied History Project at Harvard's Kennedy School of Government, Calder holds a PhD in History from Trinity College Cambridge, where he wrote his first, award winning, and widely acclaimed book, Empire of Secrets: British Intelligence, Cold War, and the Twilight of Empire (Harper Press 2013). While pursuing a PhD and postdoctoral fellowship at Cambridge, Calder was a principal researcher on Christopher Andrew's unprecedented, authorized, centenary history of the British Security Service, Defence of the Realm (Penguin 2009). This research position provided Calder, for six years, with unique access to British intelligence records. Calder is a regular commentator on intelligence and national security matters in news and media outlets both sides of the Atlantic. Calder is also a qualified English barrister and has worked on several high-profile litigation cases involving defence and security matters, providing him with expertise in the legal issues of intelligence.
A masterpiece! The intelligence report on Russia and Ukraine in February 1922 with which Spies begins could have been written on the eve of Putin's invasion a hundred years later in February 2023. A major obstacle to understanding the current crisis, triumphantly overcome by Calder Walton, is Historical Attention-Span Deficit Disorder. As Spies vividly demonstrates, we are living through the latest stage of an Epic Intelligence War Between East and West which began a century ago and shows no sign of ending. * Christopher Andrew, author of The Defence of the Realm: The Authorized History of MI5 * A vivid account of intelligence skulduggery... Walton is incisive in his analyses... A gripping, authoritative work * Kirkus, starred review * Spies is the book we have all been waiting for. Calder Walton is one of the leading intelligence historians of his generation, and his epic account - replete with human drama and tragedy - shows that Russia's struggle against the west neither began with the Cold War nor ended with the disintegration of the Soviet Union. This volume will engross the general reader and policy makers alike, not least because it provides an unsettling window into the behaviour of the second challenger, the People's Republic of China. * Professor Brendan Simms, Cambridge University *
