Spooks, Spies And Videotape - London's Secret War

It has been 70 years since the Special Operations Executive was disbanded, following the end of the Second World War.

During the war, spooks and spies kept what they did and where they worked secret, even from close family.

Now a special app has been launched which allows users to discover more about wartime London on their phones.

It was developed with the help of war veterans and uses archive material from the time to reveal which British buildings were used by spies.
