The code Da Vinci - Investigation into the true mysteries of a best-seller

According to the authors of this documentary, the American novelist Dan Brown would have taken as a starting point the the business known as of Rennes-the-Castle to write Da Vinci Code.
Inquire into the lower parts of a best-seller. Jean-Patrick Pourtal, impassioned by the mysteries of Rennes-the-Castle which it has studied for twenty years, points, evidence with the support, the many correspondences - names, the events - between the business which, at the end of XIXe, returned celebrates Rennes-the-Castle, small village of the Aude, and Da Vinci Code.
He convenes historians, writers, specialists in the religions, journalists, the mayor of the village and even the secretary general of the priory of Sion.
Each one of them revives these strange events.
As in the book, the business starts with an assassination. Antoine Gélis, priest of the village of Coustaussa, is found lying in his blood on November 1, 1897. In spite of the many indices, the crime remains mysterious. The victim was close to Berenger Saunière, priest of Rennes-the-Castle, the close village. The two friends seemed to share the secrecy discovered by the Saunière abbot during work which it undertook in his church.
Nobody will never know what it put at the day, if these are not documents that it translated in Paris.
The film recalls the discovery of the treasure, the travel of the priest in Paris, his visit of the Saint-Sulpice church then of Louvre, where it was delayed on the Shepherds of Arcadie, a Chick table which curiously points out a tomb located beside the village. With each stage, it raises the enigmas which the priest left behind him. On his return, the abbot is taken of a builder fever.
Which treasure could well have found to undertake of so great work? One evokes that which the Visigoths would have reported of Jerusalem. It restores the church, which it devotes to Marie Madeleine and in which it seems to have wanted to leave the many ones and strange information.
For some, Marie Madeleine would have remained in the south of France, taking along with it the body of Jesus.
One returns from there here to the thesis developed by Dan Brown in his book, on the relation which would have linked Jesus with the latter. But the mystery remains and the investigation continues…

The secretary general of the priory of Sion affirms that ritual priory of Sion such as they are described in the book have nothing to do with reality.
On the other hand, it does nothing but maintain the mysteries and rumours while answering, after a hesitation, “I cannot answer you” when the journalist asks to him whether the priory of Sion hides and transmits secrecies. If that is not the case, why not simply not answer “not”.

In the absence of raising the veil on the mystery, this report makes it possible to discover (or rediscover) a superb area full with mysteries (and not inevitably in connection with Da Vinci Code!)
