JOHN WILKES (Richard Doyle)
Wilkes is an Australian of the exceedingly macho variety. In his late 40's, Wilkes has been all around the world -- at least the desolate parts of it. He's a real treasure hunter, that's quite obvious (although he won't talk about it unless exceedingly drunk or well-seduced). Wilkes believes he has the secret of the treasure of Rennes-le-Chateau. He believes the secret will make him incredibly wealthy. But he ought to be careful to whom -- and how loudly -- he brags about it.
