National Geographic and the International Spy Museum bring you an interesting look at history through declassified documents, nothing too in-depth on each document though. Enough to make you think a little harder and possibly do a bit of research onto the subjects that grab your attention. The various documents span years – from the Cold War to World War Two back to the days of the Civil War and some go back much further.

Basically you are presented with a (sometimes poor quality) photograph of t

Mr. Allen has written an interesting book. He briefly discusses 50 of the most important/prominent espionage stories in history. The only issue I have with the book is the discussion of each story often seemed too brief. Most sections only contained three or four pages, giving only the briefest glimpse of the incident. In spite of this, the book works well as an introduction to espionage. [return][return] The title is somewhat misleading, while the book attaches some type of document to each of ...more

Really enjoyed this book. I am a history buff, and the background of the 50 documents gives a cool perspective of many events in history. There were a few typos in the book, but they didn't distract.

Not a very in depth book at all but, it gives you a quick overview of some of the most important spy cases in history. We have Benedict Arnold, Aldrich Ames, Robert Hannsen,Jonathan Pollard, the Walkers and many others mentioned in here. This is probably a good book for a younger reader who isn't knowledgeable about these cases as it would probably induce them to read more detailed books about the cases that interest them
Maybe this book is for a history buff. I was hoping it would ignite interest in history by learning a little dirk... but it was mostly stuff I had no prior knowledge of or was just plain not worth writing a book about. If things are declassified past the point of anyone caring then maybe a book shouldn't be written about it because most of these didn't sound like anything worth keeping a secret about.
This book written by the curator of the Spy Museum takes a look at secret documents and the espionage stories that go with them. From stories of the Cambridge 5, Aldrich Ames, Robert Hanssen and Benedict Arnold the stories are pretty brief but interesting and the photos of the documents they show are pretty cool to look at.

A book chronicling some of the most important formerly classified pieces of intelligence/instances of espionage in history. A pretty interesting grouping of pieces, with some fun stories and some crazy older issues it brought up. Not too bad.

A bit repetitive, but interesting & informative. This covers a broad range of declassified history, from the Spanish Armada to Al Qaeda. I wish it focused less on the Cold War, even if that era did generate more government secrets than any other.

50 summaries of documents declassified by US government. Circumstances around documents summarized and implications on history noted. Several spy stories included. Very interesting read!

Not worth the time. Pretty boring.
Great read to ingest small snippets of formerly classified documents.
