"Secrets and Spies" - Reader's Digest

If you have any interest in World War II history, or in the history of espionage, I highly recommend the book Secrets and Spies. This is a condensed compilation published Reader's Digest. It is excellent, and would be an especially good WWII primer for junior high and high school students. Most of it is fascinating reading. Included in it, by the way, is the real story behind the movie The Great Escape. I got my copy decades ago, and have enjoyed reading in it ever since.
