A good thriller in the end, but not THE thriller of the year, no. And if you like historical atmospheres under the IIIrd Reich, I would advise to darken without waiting in Philip Kerr's universe and his no less FABULOUS "trilogy Berliner".
Moreover, a small publisher to succeed, thanks to Gérard Collard, out of anonymity, stand out hundreds and hundreds of books that appear, then yes, if only for that this book deserves to be advised and read. For it is at least as good as most thrillers of big plants, with the difference that has certainly been produced with heart and passion.
