It was a bit of a difficult read. Knightly is a journalist for the Times newspaper in London. He was given this assignment by the Times and got permission from Russia to visit Philby for this book. He spent 6 days with Philby. Its odd he extracted this much data. With that said, some of the info in this book is found in other books, Philby's book, 'My Silent War', MacLean's book, 'A Divided Life' so there was a chapter at the beginning on St. John, Philby's father, that added some insight to Philby, the man. Of all of the books I have read about this collective, I think the line, 'The greatest jester, reaps the most praise' holds true. Far too much emphasis was always placed on Philby's life as a spy and how the Russian's allegedly benefitted, winning a paltry praise. I agree that he likely did this standing in his father's shoes. His father, too, was greatly over-rated for his alleged achievements and for all Philby said condemning his father for the way he treated his mother, Philby treated all of his wives as poorly. He may never have hit his wives but he neglected all of them and he distinctly and grossly abused her, denying her financial support and he certainly treated his children far worse than his father treated him, in gross neglect (essentially as they did not exist). He ended his career in his 40's and lived out his following 30 years in a little tiny apartment in Russia with his only 2 rewards, being driven in a car with the so called title of a 'general' and being buried 6 feet under in a hole where None of his family come to visit. If it were not for these books, written by journalists seeking their own personal fame from them, no one would even remember Philby. Philby used his career as a spy as an excuse to become an alcoholic, to have multiple affairs while having multiple wives and cheating on all of them, for foreign travel at the expense of the taxpayer and giving British and American taxpayers nothing in return for their investment. Basically, he was just a loud-mouthed, self-entered, sleezebag who thought far more of himself than everyone else did collectively, although it is the sleezebag who sells books. Both the UK & the USA would have benefitted without him.
