This is a historical fiction about Elizabeth Park. Elizabeth park was a British secret agent in the prelude to the second world war. She was the agent who stole first the enigma code machine for the British and later the bombe which was a Polish prototype computer for codebreaking. This book was exteemly interesting and more so because it is based on a real person. The picture it presents of the diplomatic community however is not very diplomatic. The amazing thing is not how little they accomplish but that they accomplish anything with their condescending attitude and confidence in the inferiority of all other people. Another interesting thing about the book is how people can be changed. The book shows how Mrs. Park who wanted nothing more than to love her husband and have a family through her husband’s actions is slowly pushed toward the intelligence service. Mrs. Park even though her methods were unethical made the world a better place. People can learn how by refusing to give in they can build something greater than their wildest dreams.
