Spymasters

This series takes us back through the centuries and looks at the most famous spies - men and women who wield real power, pull the invisible strings, choose the operatives and establish the methods used by the secret services of the world. They are the cold eyed, ruthless servants prepared to do anything to serve their political or royal masters. We are taken through dark corridors, smoky rooms and underground tunnels into the worlds of the people who watch and collect information on anyone they want. They lay before us the codes and cyphers and they tell the stories of the most infamous spymasters of all. (Viasat)
