|summary=Leave reading West's introduction to the end and dive straight into Masterman's formal (but highly readable) report into the activities overseen by the XX Committee for intriguing insights into some of the real successes of WW2 ~ and some of the ideas that came to nothing. West's introduction makes much more sense reading it after you have some idea of what he's talking about. A fascinating historical document that still resonates with what might just be still going on today. Recommended.

This ''Vintage'' re-issue of Masterman's account of the work of the Twenty Committee is subtitled the ''classic account of World War Two Spy-Masters''. That's a somewhat misleading tease. The book isn't really about the spy-masters, very little information is given about those recruiting, turning, running and protecting the spies. More information - but again relatively little - is given about the spies themselves.
