I first discovered Philip Kerr on a visit to Partners & Crime bookstore in New York in 2007 (now closed unfortunately). A chat with one of the staff seeking some recommendations for new crime writers introduced me to Philip Kerr, I have been a fan of his Bernie Gunther series ever since. Gunther is a tough murder detective struggling to maintain his integrity, pursue criminals and steer through the political maze of Nazi Germany. Gunther is a great character that you return to in each novel with enthusiasm, Kerr also has a good eye for historical detail and the realities of surviving and/or flourishing under the Nazi regime.
Prussian Blue is the 12th in the series, each book stands alone and their is next to no dependency on having read it’s predecessors so you could jump in with Prussian Blue or start at the beginning with March Violets. Prussian Blue starts in 1956 with Gunther working in a hotel on the French Riviera trying to lead a quiet life, he becomes entwined in an operation ordered by Erich Mielke the head of the Stasi and things go downhill from there. The plot flits between 1956 and a case that Gunther had in 1939 just before the start of the war. It’s tense, atmospheric and at times quite humorous, well worth reading.
