Just catching up on this from last week, as the Holy Blood, Holy Grail authors went down in flames. I particularly enjoyed the judge's reasoning that they'd failed to prove that Dan Brown had stolen the central theme of HBHG "because they could not accurately state what that theme was." And do stick around the article long enough to see the judge slap around Brown and basically call much of his testimory misleading or fraudulent. Good times.
And instead of wasting yr time reading either HBHG or (not that you'd even consider it) Da Vinci Code, may I recommend instead Rat Scabies and the Holy Grail. Written by former NME music journo Christopher Dawes, it's the ripping tale of his adventures stomping through the esoteric wilds of southern France with legendary punk drummer Rat Scabies. And until some yet-to-be written Da Vinci Sequel starring Capt. Sensible shows up, the Dawes book is pretty much the gold standard in kickass heresy and esoteric foofarah. Interestingly, the 3rd author of HBHG, Henry Lincoln (who was not part of the lawsuit) shows up several times in RS&HG.
Here's an interview with Dawes and Scabies, from Fortean Times (w/ a few pics, even).
