Dan Brown and The Da Vinci Code

It seems that everyone is coming out of the woodwork to try to get their 50 cents...claiming that Dan Brown had stolen the plot for the Da Vinci Code. This book based on the theory that Jesus married Mary Magdalene, that they had a child and that the blood line survives. I don't believe this to be true...but I admit I enjoyed the book tremendously. I am waiting impatiently for the movie to be released (Tom Hanks) this May...unless this is taken to court. Hopefully not.
