Checkout Billmon's Whiskey Bar on Porter's resignation inCIA Confidential. And read why I think that Intelligence Services Are Not `Intelligent'. Finally, six recommended spy novels: Eric Ambler'sThe Mask of Dimitrios; Graham Greene's The Third Man: Alan Furst's Dark Star; Charles McCarry's The Tears of Autumn; John Le Carre's Tinker, Tailor, Soldier, Spy ; Len Deighton's Berlin Game. I would recommend reading everything by Ambler, Greene, Le Carre, and Furst (a relatively new author who has written great stuff using Nazi-occuppied Europe, epsecially Paris, during WWII as backdrop). As far as Deighton and McCarry, I would recommend their earlier novels. The more recent ones are not so good.
