Good book if you're in a thriller mood. Keeps you quite engaged even though you already know the actual ending of it all because you want to actually know how the story and the characters eventually end. 

Some of the problems with the plot and writing - 

after reaching the island in the sefond half, it becomes sort of obvious how it will end. The writer, however, does a good job of distracting you from that part by engaging you in sex and a bit of emotions. 

I did NOT enjoy the fact that the cold-blooded murdered spy just kept on neglecting to kill that ONE woman at the very end and brought about the defeat of his country. I mean COME ON. That really was stupid after all his cold-bloodedness throughout the chase.

And the continuous repetition by EVERY character ever, about how 'Die Nadel' was the only spy of value in Germany and how the entire war depended on him. After the third time, I was just constantly eye-rolling. 

Thr author kept introducing new characters with names and  backgrounds of a full page even though they are hardly mentioned for two lines. This was happening even in the final act. Felt like it needed a bit of editing. 

Anyway, despite my seemingly many problems with it, I did quite enjoy this WWII spy-thriller. It could have been  better edited, but nevertheless it's not a waste of time, I can assure you. 

Additionally, I did learn about the FUSAG and realised the reason behind the hue and cry of the landing of the allies at Normandy. So yay to that.
