This book was enthusiastically recommended to me by a couple we met while traveling in Europe. This is a GREAT book! It is the story of criminal, Eddie Chapman, who become a German spy and then a British double agent during World War II. I really enjoyed this book and is perfect "prep" reading for our trip to England in 2015!
Here is a 2011 BBC documentary presented by the author and includes an interview with Chapman!
