Holy Blood,Holy Grail

Iteresting to see the authors of The Holy Blood and Holy Grail are suing Dan Browns publishers over the Da Vinci Code,saying that they had a conflict of interest over the theme of both books.The authors of HBHG are named Leigh and Baigent,quite interesting that the protagonist in Da Vinci Code is Sir Leigh Teabing.....Teabing being an anagram on Baigent...ps Brown does refer to HBHG in course of writing.
