This is another one I read recently. As the name suggests, its the story of Operation Mincemeat (the deception operation in the run up to the Invasion of Sicily involving "Major Martin"). The book assumes you have very little prior knowledge of the Operation, British Intelligence in WWII and the spy rivalry in Spain; so it explains all of these topics. However, it doesn't do so in a way that is annoying for those already aware of these topics. GOOD: Gives a very complete picture of the Operation and doesn't glance over any details Includes photos of the letters and items carried by "Major Martin". I didn't know these existed in the public domain, so I was pleasantly surprised. Flows extremely well. MacIntyre is an historian, yet writes like a novelist -- it keeps you interested throughout, and doesn't get dry. A good mix of cold facts and amusing stories. As you may expect, there are a good number of references to Ian Fleming's eccentric plans, and many of the unique personalities working in intelligence. Provides a good view of British Intelligence in the first half of WW2, even though it is not the book's purpose (the purpose, of course, is to discuss Operation Mincemeat). Everything mentioned in the book is tied directly to the Operation. For example, the book describes the workings of British Intelligence by how it related to the Operation. Provides adequate information about the participants' lives (even post-war). When I'm reading, I always want a to know about of the key participants, not just how they acted in such a time period. Many books don't do this. MacIntyre did quite a bit of research for his book -- he didn't just assemble information that was already out there. Notably, he found out the inspiration for the Operation came from a 1939 Ian Fleming memo. He also confirmed "Major Martin's" identity. BAD: MacIntyre does go off on tangents to provide information on the key participants. So you might have 3 or 4 pages dedicated to the life of a participant that doesn't directly discuss the Operation. As I said, I like this, but others may find it irritating and irrelevant. I only thought that one tangent was excessive. This is another very good book. I highly recommend it.
