"Blunt himself was responsible for editing the MI5 monthly briefings which were handed to Churchill, so was in a very good position to bury everything that Churchill may or may not have wanted to know about Agent Josephine and Arnhem."

"The arguments that Blunt was making about his own treachery are the same ones that some of the British jihadis were using to justify their own actions."

"Things haven't changed as far as the Russian leaders view the world."
