This isn't a thriller and it can be very dry and tiresome at times. However, from the academic standpoint , this is an interesting work on the CIA.
Good or bad, this book was a product of its times, and I understand that. It wasn't fashionable in the 1970s to spy, and there were some controls needed on CIA.
However, I think Agee goes to far in releasing secrets.
Agee takes the reader through recruitment, training and CIA life. If he had stopped there and left out designations, cover and agent names it would be a sort of dry but informative work.
Aldrich Ames sold names and operations for money to the Soviet Union. Phil Agee sold them to a book publisher. I see little difference.
