Jason Matthews
6 Stars Best New Espionage Everything
I have reviewed over 300 books on intelligence, almost all of them non-fiction. Apart from the George Smiley series by John Le Carre the only other fiction book I can think of that garnered my respect was Tears of Autumn by Charles McCarry.
This book, by a former SE Division (Soviet Division) Operations Officer also known as a Case Officer (C/O) is SENSATIONAL. I bought it at the airport when my planned reading for the return flight turned out to be junk (Life After Google).
