As someone fascinated by the mystery of Rennes Les Chateau, the Priory of Sion and the Da Vinci Code i read this book with interest. Picknett and Prince debunk many of the myths surrounding Rennes Les Chateau, pointing out that documents concerning King Dagobert, Merovingian bloodlines and the priory of sion are later additions and forgeries. They also take a fresh look at other aspects of the mystery, such as the interest of a Hapsburg Duke in Rennes Les Chateau other less explored areas.
They also debunk some of the theories of more fanciful writers on the subject.
On the downside, the book goes into great depth on the subjects of french politics and secret political groups. I found this these sections of the book quite dense and difficult and i lost some interest and even skipped a few pages. Overall though, its another interesting and well written book from Picknett and Prince
