I really don’t understand why the authors of The Holy Blood and the Holy Grail are suing Dan Brown for using their ideas. Surely if you have a good idea then you’e happy if other people publicise it too.

Maybe they just don’t like their work being associated with something quite as trashy as The Da Vinci Code.

Or maybe (and I think this is far more likely) they’ve realised that their twenty year old book is all a bit embarassing and they would rather that Brown didn’t go round reminding people of its existance.
