Eva and her family have fled Russia for Europe but WWII is brewing. A charismatic and mysterious Englishman takes Eva under his wing and recruits her as a spy from where she becomes fully immersed in WWII subterfuge in the US. Later in 1970s Oxford, the truth of her past is slowly revealed to Eva‘s daughter. It was consistently absorbing and then became so gripping I couldn‘t look away. I enjoyed the spy focus being the US rather than Europe too.
