This Russian spy story just gets better and better. First a young, attractive Russian woman called Anna - with a penchant for uploading suggestive pictures of herself onto Facebook -- is seized in an FBI swoop for being at the centre of a Russian espionage network. Next, it emerges that the agents from Moscow had outwitted the FBI by going back in time. Aware that electronic messages — via mobile, or online -- are are an open book to any decent spook-catcher, they simply learnt from the past and used invisible ink and messages in buried bottles to send information their colleagues in South America. Some of the spies even are said to have been schooled in Morse code. It must be handy for our competitors; for Russia and China in particular, to know that we in the West are so blinded by technology that we have utterly forgotten the lessons of the cold war.
