A story of espionage and extremism the world's first secret service, and the terrorist threat they faced. The end of the 16th century England is a pariah state on the edge of a largely Catholic continent. For the protestant Queen Elizabeth I, the enemy is everywhere the Pope has given licence to kill her. This legion of threats demands a shadowy new army. And so the age of espionage begins. This is the story of the Cecils, the spymasters who ran the world's first secret service. Their counter-terrorist network reached into the very heart of the Catholic enemy, and they secured the Britain we know today. Includes subtitles for the Hard Of Hearing
