IS THE STORY OF DA VINCI CODE WRITTEN BY DAN BROWN TRUE?

I don't know if it is true. But it is pretty interesting. Anyways, now my mind is open to anything. After I read the book, I looked at a picture of the Last Supper we had at home and I could see the woman next to Christ. The picture has been with us for years and I had never noticed that. It made the whole thing a lot more interesting and believable. I'm sure there must be something to it even if the whole thing might not be true. But I'm not commenting on whether it's totally true or not till I do some more research on the matter.
