The claim:

“Serious researchers like Antoine Captier, Jean Pellet and Gérard Dutriat have attested they have seen the original photos from Corbu’s time. You have to remember Corbu already talked about the parchments long before De Sède’s book came out. It is now believed Corbu allowed Plantard and the Chérisey [sic] to make carbon copies of them. They worked them into the parchments we know today and added in some simple codes like the raised letters in the small parchments that would support their claim to the French throne”

Rennes-le-Château researchers claim they are interested in Philippe de Chérisey. Philippe de Chérisey wrote in a letter to Pierre Plantard that it would be a good idea to invent the story of the parchments because the story of the Dead Sea Scrolls was popular during the 1960s.

Except that it's only THEIR version of Philippe de Chérisey that they are interested in. Their version that feeds their fantasies.
