Ms. Atwood wrote a clear picture of Marguerite Harrison , she was bright , daring and complex. I went on to do some research of this woman after reading the book and was amazed at her tenacity in the Russian jail system, it might be a good follow up to read one of Ms. Harrison' own books. I can see that it may have difficult to get more personal if she did not leave any trace of diaries or journals. It may have been helpful to explore her relationships with her mother and her relationships with men, her son to add to the picture. I was fascinated with her fearlessness and espionage skills . She is an unsung hero of her day and so this story needed to be told - thanks to the author . ( )
