'An overwhelming, immersive, suspenseful success.' - Lee ChildAuschwitz, 1944. Alfred Mendl's days are numbered. But he has little left to live for - his family were torn away from him, his life's work burned in front of his eyes - until a glimmer of hope arises as he watches a game of chess. To the guards Mendl is just another prisoner, but in fact he holds knowledge that only two people in the world possess. The other is working hard for the Nazi war machine.
