In 1940s Portugal, everyone is willing to trade secrets if the price is right. Britain stands alone against the forces of Nazi Germany. Livvy Redmond is a young newspaperwoman determined to serve Britain’s spymaster in the face of danger. When she arrives in neutral Lisbon, she discovers a city full of spies, refugees, and the secret police. At an elegant party to meet a double agent, Livvy witnesses him fall to his death from a balcony and must now determine what secrets he wanted to pass her. Further complicating matters, she must guard the man’s young daughter from sinister people trying to kidnap the girl. Gambling on the assistance of British embassy staff, Livvy commits to uncovering the truth while keeping the orphan safe. With spies and traitors lurking around every corner, Livvy must race against time to learn the secret someone has already killed to keep hidden – and is willing to murder again to protect.
