Robin Griffith-Jones, the Reverend and Valiant Master of the Temple, says absolutely not. He has written an upcoming book called "Da Vinci Decoded" which debunks the best seller.
On Oct. 13, 1307 -- Friday the 13th -- Philip the Fair, the king of France, arrested the knights on charges of heresy, accusing them of everything from ritualized sodomy to urinating on crosses, said Griffith-Jones. He seized their treasury and kept it all.
The arrests, interrogations, torture and trials took five years and were spectacularly brutal, said Griffith-Jones. The knights were wiped out and buried in The Temple Church -- their secrets buried along with them.
But do those secrets include information on Mary Magdalene? Griffith-Jones says no.
"The real secret of the Knights of Templar has nothing to do with Mary Magdalene and everything to do with international banking," he said.
So does this put an end to the speculation surrounding the mysteries of "The Da Vinci Code?" That's highly unlikely, considering a film version of "The Da Vinci Code" is set to be released in 2006, directed by Ron Howard and starring Tom Hanks.
