I thought I had read all the important main books on the Cold War, but Ben Macintyre comes through and gives us a true life narrative of one of the West's greatest heroes - Oleg Gordievsky. A man who helped, particularly the UK, inform the goings on of the KGB and all the Boris and Natasha's and helped hasten the end of that nasty politik.
This would be best read in the autumn on a train in the UK. Knowing that something good came out of all this, after all. Ben Macintyre probably will be sitting behind you. He has your back covered.
