The Bernie Gunther novels began with a trio of critically acclaimed crimes noir, two set in pre-World War II Nazi Germany (March Violets, The Pale Criminal) and one in the immediate aftermath (A German Requiem). Over a dozen years passed before Kerr returned to the character, a former soldier who later worked as a private investigator, whose career he has continued to chronicle since. You can find a very good summary of the novels here, written by Philip Turner.
