Although this is the originality of these three policemen, the historical aspect does me little interested. The fact that the character meets all the "gratin" not the Reich is indeed the best aspect of intrigues, which become fairly unlikely (especially in the third part) ... As for the debate on the guilt of the people German, well ... that's not really what I look for in this type of reading. But the overall feel of a Nazi Berlin in ruins and is well made. As for the plot, they are certainly well-crafted. The side "Philip Marlowe" character is not bad either, although I regretted at times it is a little routine. Despite these reservations, reading quite honest, and well above the all-comers thrillers anyway.
