The second in David Downing's critically acclaimed WWII espionage series

It’s the summer of 1939. British journalist and longtime Berlin resident John Russell has just been granted American citizenship when his girlfriend, Effi, is
arrested by the Gestapo. He had hoped his new nationality would allow him to stay safely in Germany with Effi and his son, but now he’s being blackmailed. To
free Effi, he must agree to work for the Nazis. Can he turn this situation to his advantage?
