Dark Star by Alan Furst is a great spy novel about a Soviet (Polish Jewish) journalist in Western Europe who gets involved in espionage.
Pravda foreign correspondent Andre Szara starts out by doing small spying tasks for the NKVD until his whole life is taken over by espionage. Then he gets involved in trying to save Jewish lives by trading some German information with the British.
It is a good spy and historical novel and a fun read. I enjoyed it very much.
