Episode synopsis
During both World Wars, Britain's counter-espionage service proved highly effective - no enemy spies operated for more than a few days, and many were "turned" to send false intelligence back home. Later, MI5 faced criticism for failing to expose the Cambridge spies, then remodelled itself as a counter-terrorist organisation.
