Alfred Vicary was pulled in to serve the MI-5 at the beginning of WWII. Whilst most German spies have been routed out, there is a division which has buried their intelligence officers deep in Britain. It's been allocated to Vicary and his team to stop these spies sending out crucial information about the upcoming invasion. But he's only a professor of history...The beginning of the book felt messy. There were a lot of characters being introduced and timeline was slightly back and forth within a few years. So, I quickly got confused however after a handful of chapters, the story settled down and the main characters are now on focus. Up to halfway, it was slightly slow but after halfway, it was suddenly Bam! Bam! Bam! Fast paced and action packed. I really liked this part of the book. Unfortunately, since I'm not up with the technicalities and lingos of espionages and was strategies, I was slightly lost. In any case, it didn't drag me down too much.
