A first class war time thriller this. It follows the familiar - but rarely successful - storyline of what Britain would have been like if the Nazis had invaded these islands and took over the country in 1940.
It follows the story of man caught up in a very difficult position - he is a fluent German speaker and so he is called upon to be an interpreter for the senior officers of the occupying power which leaves him hated by the loyal Brits but still mistrusted by his German masters.
To complicate things, our hero, Nick Penny, then becomes one of the most senior members of the growing Resistance movement and his double life causes him, his family and his friends many problems and agonies as the story grows.
This has more validity than some of the other books on the subject I have read in that it seems to portray a more honest and accurate picture of what life would have been like under the Nazis where not every Brit would heroically fight the invaders and many would actually view the occupation as an opportunity for self-advancement.
This is a well-written and well-researched book which makes for great holiday reading. It has all the elements you want from a page turning thriller - chases, battles, double-dealing, blackmail etc - with more thought-provoking elements such as the true nature of occupation, what would Britons have done when we first saw hints of Jewish persecution and, indeed, would we really be as brave to take on an enemy as we imagine we would?
