A Shadow in Moscow by Katherine Reay

Both M16 and the CIA are betrayed by a moleat the highest level endangering the lives of many and especially two very successful female spies. Set over two time lines on 1954 and the 1980s, the story goes into several cities in Europe covering many people and especially families who will be completely disrupted by any breach in the layers and layers of deception, carefully built over the years which made them bothso successful. Two strong women - one the older Ingrid who is a dutiful wife, a charming hostess never drawing attention to herself with British roots and who becomes so good at her job and then there is Anya, just back from Georgetown University, leaving her heart behind in America and now in a field with access to top secret information, living life on the edge as a spy for the CIA. It was a complicated story with many twists in the tale, but well balanced and very enjoyable. Sent by Harper Muse for an unbiased review, courtesy of Netgalley.
