June 1940. Britain is Europe's final bastion of freedom - and Hitler's next target. But not everyone fears a Nazi invasion. In factories, offices and suburban homes are men and women determined to do all they can to hasten it.

Throughout the Second World War, Britain's defence against the enemy within was Eric Roberts, a former bank clerk from Epsom. Equipped with an extraordinary ability to make people trust him, he was recruited into the shadowy world of espionage by the great spymaster Maxwell Knight. Roberts penetrated first the Communist Party and then the British Union of Fascists, before playing his greatest role for MI5 - as Hitler's man in London.

Codenamed Jack King, he single-handedly built a network of hundreds of British Nazi sympathisers, with many passing secrets to him in the mistaken belief that he was a Gestapo officer. Operation Fifth Column, run by a brilliant woman scientist and a Jewish aristocrat with a sideline in bomb disposal, was kept so secret it was omitted from the reports MI5 sent to Winston Churchill.

In a narrative that grips like a thriller, Robert Hutton tells the fascinating story of an operation whose existence has only recently come to light. Drawing on newly declassified documents and private family archives, Agent Jack shatters the comfortable notion that Britain could never have succumbed to fascism, and celebrates - at last - the courage of individuals who protected the country they loved at great personal risk.

I have been an avid reader of anything to do with WWII and the Holocaust. There are very few things that could shock me about that era. Then I read Agent Jack and had my mind blown.

I don’t know why I was so surprised to read that there were Nazi sympathizers in England. I shouldn’t have been. Considering that Germany is a little over an hour (flying time) from England, it should have made sense. I will admit, it threw me off the book for a little bit. Once I was able to wrap my mind around that, I was able to get somewhat get into Agent Jack.

Agent Jack took me six days to read. Four of those six days were spent traveling. Ever travel with three kids? Then you understand why it took me so long to read. The other reason why it took me so long was that I had to force myself to read and finish the book. Which, if you have done it, isn’t a good thing. I also found it extremely dry. There was a lot of information to process.

There were parts of the book that I found interesting. It involved the MI5, which is England’s equivalent to the US’s CIA. I found it fascinating the politics that went into everything. I haven’t read a lot of books on the MI5, but what I have read caught my interest.

Agent Jack had a wide assortment of people as main characters. But the main guy, the bank clerk who was essential to everything, was fascinating. He kept tabs on 500 people without blowing his cover. Which, to me, is impressive. I can’t even keep tabs on three people without running into issues.

I liked that the author chose to portray the Nazi sympathizers in a way that explains why they felt that way. A lot of these sympathizers were refugees from WWI and harbored anger towards England. They would do anything to help Germany, which included betraying the country that took them in.

The author did a fantastic job of showing what happened to all the key players, good and bad, at the end of the book. I will say that I was inscensed over how Eric Roberts was treated. That poor man gave years and to get treated like that!! Shameful.

I would give Agent Jack: The True Story of MI5’s Secret Nazi Hunter an Older teen rating. There is no sex. There is mild language. There is mild violence. I would recommend that no one under the age of 16 read this book.

I would reread Agent Jack: The True Story of MI5’s Secret Nazi Hunter. I would recommend it to family and friends.

**I voluntarily reviewed a complimentary copy of this book**
