Sounds really mysterious, right?
The story's really not all that exciting, though.
As has been reported for a little while now, the Vatican is releasing a book containing the documents from the 14th century heresy trial of Knights Templar, a religious military order founded in 1118 to protect pilgrims in Jerusalem during the aftermath of the First Crusade.
The centerpiece of the book is a document discovered in the Vatican Secret Archives in 2001 that suggests that Pope Clement V initially absolved the Knights Templar of the charges of heresy against them, but later reversed his decision under pressure from King Philip IV of France, who historians believe probably owed money to the order.
So, a decent dose of intrigue and scandal, I guess, but no Holy Grail.
