Anya Pavlovitch is a Russian ex-pat working for the U.S. Office of War Information (OWI).
Macdonald 'Mac' Benson is a member of the newly formed O.S.S.
The time period of this trilogy of adventures of these two people is 1943. The War Against Japan in the Far East was well underway but the Japanese were still very much in control of virtually every part of the Asian coastal region from Korea to Vietnam.
When the first mission the two would go on was started, they had not yet met and when they do get pushed together for that assignment, they immediately decided they really had no use for each other. Making things even more interesting is that when the two are ordered to head to Shanghai, they shared a common mission but had really two quite different objectives. It is hard to form a trusting partnership when truth is hidden. And yet both will learn that survival will depend on that trust.
The author was kind enough to provide a limited character sheet for each of the two main characters in this series. According to those, we learn that:
Pavlovitch is 42 years of age, born in Moscow in 1902. She has jade green eyes with Titian red hair which had not yet been touched by any gray. She stands 5'4" tall and has a slender build. "Her petite features and complexion similar to vanilla ice cream gave her an air of youthfulness, even though the wrinkles at the corners of her eyes stood out". When we first meet her she is working as a translator for OWI, being an expert in several languages.
Benson is 36 years old, born in Maine. He has blue eyes and brown hair. He is 6'1" tall with a 'brawny' build. On our first encounter with him he is working in the U.S. Navy as an Intelligence officer.
Benson's opinion about Pavlovitch is not very high. Her rating of him is even lower. It makes for an interesting mission.
