Between real thriller based on a somewhat implausible plot and a popular science book which we do not clearly distinguish the boundaries between what is scientific fact accepted by the research community and what is still only supposition or theory more or less smoky, this novel is a bit disappointing. This is not a plagiarism of The Da Vinci Code, but it contains the same ingredients, the same structure that begins with the death of a great man and the appointment of a specialist wrongly convicted in cryptology and related sciences must leak and conduct his own investigation to prove his innocence. In conclusion, thriller side is not great, popular work side, it lacks a few serious and documentation.
