M was a double agent during the cold war, working on the side of the west. But when the Iron Curtain fell, he felt abandoned by the secret services he risked his life for.

M's story is told by Eleni Braat, associate professor of international history at Utrecht University and Ben de Jong, research fellow at Leiden University. They've been interviewing him in depth for their research on what happens to spies when their secret service days come to an end.
