A worldwide phenomenon- Da Vinci Code

Having read the book, now I know why it is a mega bestseller, 40 million copies sold since its publication in 2003, more or less made its author Dan Brown a multi millionaire.
The content of the book is controversially sensational, sensationally controversial. Never would I expected that it contained so much believable information ( even though it is fiction). The chase drama is something , A Matter of Honour by Jeffrey Archer and the Search for the Holy Grail is definitely something like Indiana Jones , Raiders of the Lost Ark and Last Crusade.
A wonderful reading indeed. There is a picture of the last supper, see the arrow pointing to a feminine figure, that could be Mary Magdalene sitting together with the Apostles. I have not noticed 'her' in the picture before.
