I really enjoyed reading this book, it had a great idea overall and that it worked in the thriller novel. I enjoyed how good the use of the historical setting was and that the Cold War elements worked overall. The characters were everything that I was looking for and enjoyed what I read. Dominc Adler does a great job in writing this and creating the characters in this story.

For those that like alternate history stories, this one may be of interest.
I gave it the following SCORE:
Setting: Late 1950’s in Great Britain, now occupied by the USSR after the allies, without USA’s involvement, have defeated the Germans
Characters: The lead is Thomas Fairburn who was born in Great Britain and has, for his own reasons, willingly become a KGB officer, tasked by Britain’s security leader, Kim Philby (yes, that Kim Philby) to discover who has been assisting a dissident author's defection to the USA. A large supporting cast of British, Russian, and US authorities are involved, including references to historic characters in their new, revised roles.
Overview: Fairburn has his work cut out for him, not only because he has switched allegiances, but also due the shifting and undetermined roles of those he trusts and reports to. He continues throughout the story to question his real assignment, the reliability of his contacts, and whether or not he believes he is doing the right thing.
Recommendation: I rate this book 4 stars
Extras: The tale constantly changes perspectives and, with the complexity of the new political environment, demands attention to who is motivated to do what and why. The eventual role of the US is particularly intriguing.
Thanx to NetGalley and Lume Books for the opportunity to provide this candid review.
