On a visit to her mother’s isolated country home in 1978, Ruth Gilmartin learns that her mother, Sally, has been living a lie. She’s really a Russian named Eva Delectorskaya, and during WWII, she worked as a spy for the British Secret Service. Now Sally/Eva believes that her life is in danger, and she needs Ruth’s help to find her former spymaster, Lucas Romer.

During wartime, Eva is sent to America on an assignment of seduction and deceit. When a second mission becomes deadly, she is convinced someone must have betrayed her team. With the killer or killers closing in, Eva goes on the run and into a lifetime of hiding. Thirty years later, she must confront the traitor before it’s too late.
