I would not have read this book had I not first read "The Secret War Against the Jews" by Loftus & Aarons. Their information was so incredible I felt I had to check it against other published works. The book is supposed to show how Britain's MI6 and MI5 handled the Philby spy case, as well as his three spy-pals. It was said there was a fifth spy in the bureau, one that could not be ascertained. According to Loftus & Aarons, this person actually was Kim Philby's father, Harry St. John Philby. Unfortunately, he is not mentioned in Spycatcher. However, you won't be disappointed with the details of being a spy, planting devices, outwitting the other side, and outwitting your own side in an effort to maintain secrecy. The author retired from MI5 in 1976; therefore, it covers his active work up to that time.
Highly touted book that was initially banned in Britain because it was too truthful about the nature of British intelligence services.
I truly remarkable telling of a first hand look at the secret war during and after WWII. I was sorry to see this end.
