The Fourth Man - The story of Blunt, Philby, Burgess and Maclean

This book was written in 1980, less than a year after Mrs. Thatcher named Anthony Blunt as The Fourth Man. It is a sequel to the author's earlier book on Burgess and Maclean. Whilst a bit dated now, it is interesting and easy to read, albeit a bit subjective on occasion. Unfortunately, it bears the hallmarks of quick production. There are one or two printing errors, and some inconsistencies about dates. Nevertheless, if you are, say, going on holiday and want a good read, it's worth taking. You won't be bored.
