Remember Pierre Plantard St. Claire from that book? He died last year. Allegedly he was secretive as all get out to the end.
Ah Pierre Plantard. Descendant of the J-man himself. Don't tell me he died without leaving any offspring? Have "the desposyni" died out???
Hey did you ever play Gabriel Knight 3? They lifted the whole plot of that video game from the... "theories" in that book. It was fun :)
