The public appetite for spies, both real and fictional, seems inexhaustible. But where and when did spying begin and how has the art and craft of espionage developed over the centuries? Spies in History is a collection of portraits of some of the most famous spies we know, but it also includes some lesser known and more surprising names. A remarkable line-up of distinguished historians, scholars and writers examine the evolution of intelligence and counter-intelligence – from ancient times to the Cold War and the age of Putin, Trump and Xi Jinping – to reveal the truth about espionage and the myths that surround it.
