This is an interesting historical fiction that mixes facts and fiction. There's a thriller side but it's the depiction of an age when fascism was seen as the barrier to stop bolshevism.
A violent age and this book talks about what happened, how the secret services used violence and fascist.
it's well written and interesting even if a bit disturbing at times.
Recommended.
Many thanks to the publisher and Netgalley for this ARC, all opinions are mine
