Baldrick's proof.

To the uninitiated, I feel that there is a need to point out the point of the last three day's posts.

They do actually prove that Tony Robinson's attempts to disprove the reality of the secret discovered by the priest Sauniere in Rennes Le Chateau are corrupt.

And the really beautiful irony of this is the fact that the very thing Sauniere found is the thing that disproves it, with the much appreciated help of Tony Robinson.

Baldrick is the boy.
