Query: A Major Disappointment

I was excited to read this book but was very disappointed. The book attempted to juxtapose Robert Hannsen's life with that of Louis Freeh's but, in the end, didn't do justice to either one. The background provided to Hanssen's upbringing was informative, but after the onset of Hanssen's spying, the book simply seemed to bounce chronologically in no coherent fashion between Hanssen's spying and Freeh's career at the FBI. Paragraphs seemed to be independently written and then patched together in the best manner possible from the author's point of view, but the book laked flow. Moreover, numerous digressions into events like the Oklahoma City bombing and Ruby Ridge served no purpose other than to increase the number of pages in the book. Having read and really enjoyed Stuart Herrington's "Traitors Among Us," another book about Cold War espionage, I thought this book fell rather flat.
