We find in this book the ingredients of the Da Vinci Code. Namely investigated combining past and present more or less close. It is also based on the foundations of the Catholic religion. The comparison stops here. I find that the investigation is properly conducted smoothly and takes the reader on a very steady pace. Personally I enjoyed the end of the novel (its denouement). Indeed, in this book, the characters are not "super heroes", they have nothing exceptional and sudden actions have nothing surreal. The end of the book is not the American style ... I do not know enough about religion to be able to criticize what is stated in this book but hey it is a fiction. So it is certainly possible to criticize it as the Da Vinci Code, but the bulk of this book is to make us have a good time this is the case throughout this novel. I did not know the author but I must admit that this novel made me want to find out.
