First of all, I warn those who do not like to know too much about the plot before starting a book. The back cover reveals elements that occur only in the last quarter of the book, which is rather a shame. I think it is a thriller it is best to start with little clear history, especially as it is quickly carried away by the plot. Polar nice, well made, with endearing investigators which we also followed the daily. It makes you want to read the other books of this writer to find them.
