On Intelligence: The History of Espionage and the Secret World

From the ancient Greek and Roman origins of human intelligence to its use in the Catholic church to Francis Walsingham's Elizabethan secret service to the birth of the surveillance state in today's digital hi-tech age, Colonel John Hughes-Wilson, professional military-intelligence officer and author of the bestselling Military Intelligence Blunders and Cover-Ups, gives an extraordinarily broad and wide-reaching perspective on intelligence, providing an up-to-date analysis of the importance of intelligence historically and in the recent past. Drawing upon a variety of sources, ranging from first-hand accounts to his own personal experience, Hughes-Wilson covers everything from undercover agent handling to photographic reconnaissance to today's much misunderstood cyber welfare.
