In 1890, the French writer Joris-Karl Huysmans wrote to a young Dutch novelist he was searching for "a demoniac sodomite priest" who performed the black mass. Joris-Karl - "J.K." for the friends - needed this man for a new book about satanism which would become "Là-bas" (translated as "Down There" or "The Damned"). J.K. did find the priest... It was the Chaplain of the Holy Blood Chapel of Bruges, Louis Van Haecke. Now this "Super Satanist" also wrote a book... about the Precious Blood of Bruges!
There is undoubtedly a Code in it. Question is: a Da Vinci... or a Nostradamus Code?
