"Please donate generously to Mrs. Roosevelt's charity. Every penny raised from this series of concerts along the eastern coast of the United States will help with the resettlement and care of child refugees from war-torn continental Europe." Over dinner with J. Edgar Hoover in Washington, Tommy Haupner is shocked to learn that his forgotten and empty Swiss bank account has been topped up regularly with staggering sums of money-deposits that originate in Nazi Germany. Could this bank account have something to do with anonymous letters posted to him at home in London, their contents a single blank slip of paper on which are written two words: "NAZI GOLD"? When he returns to Britain, he soon discovers that not only is his own life in danger but also those of his nearest and dearest who become pawns in a savage game of revenge.
