My 'Eyes on the Spies' Central London tour not only reveals the locations where infamous acts of espionage have occurred but we discover how the incidents impacted on the people involved and the wider world, the human consequences and the lessons we may learn from history. Each tour has only 10 available places ensuring the group is never too large. Each tour guest uses an audio commentary receiver and earpiece. This ensures crystal clear commentary in all conditions.The tour uses the Transport for London rail network (Zone 1) to travel between the most iconic and relevant sites.
