A Man Without Breath by Philip Kerr

When winter’s final snows still blanket the Eastern Front, veteran investigator Bernie Gunther is thrust into the heart of a deadly war of secrets. Berlin, March 1943: Germany’s defeat at Stalingrad has shattered illusions of victory. Now word reaches the capital of a mass‐grave near Smolensk—Polish officers found shot and buried in the forest of Katyn. The Wehrmacht’s War Crimes Bureau and Propaganda Minister Joseph Goebbels demand proof of Russian guilt—and Gunther is dispatched to get it. In the war-zone where ideology and opportunism collide, Gunther must dig through layers of aristocracy, treachery, propaganda and murder. As the truth claws its way to the surface, survival becomes the greatest investigation of all.
