RLCResearch.com is reporting that Richard Leigh, co-author with Michael Baigent and Henry Lincoln of Holy Blood, Holy Grail, died last Wednesday, the 21st of November, aged 64. Leigh had been in the news over the past couple of years due to the high profile plagiarism court action against Dan Brown (in regards to copying themes from Holy Blood, Holy Grail for his bestseller The Da Vinci Code). I haven't seen confirmation from official sources of his death, but have heard from a number of people in the alternative community about it (heart attack being blamed) - I will update if/when I hear official word.
