If you get the chance, read the 'Station Series' books by David Downing. He has written a series of espionage thrillers, based around the character, John Russell, who is living in Berlin in the '40s with his actress girlfriend, Effi Koenen. Both take the same jaundiced view as Bernie does. They are well-written and very well researched. Read them in sequence starting with 'Zoo Station'. You will feel right at home if you love Bernie.
