I am really not going into the secret behind the mystery of holy grail but my idea is to somehow see what was the secret behind the success of this book or even if I do not worry about the success of the book, I want to write why I liked this book so much to read it multiple times. First of all, I bought this book purely because of the media publicity that it was getting. Before that I had not read anything of Dan Brown or on the same topic and I did not have much interest as well.
Once I started reading the book, it is really difficult to put it down. Dan Brown has learnt the art of closing each chapter in such a way that you want to know what happens next. This is something that he has done in all his books, though his earlier books became famous only after “The Da Vinci Code”s success. This is an excellent way of writing a mystery or thriller book. Reader is not only waiting for the last page of the book but is equally eager to read next chapter and next page.
The second thing that makes it a good read is a controversial and mystery topic. Since it is so difficult to conclusively prove what happened in history, it is easier to use half information for a completely new angle to historical facts. This is something that he has done really well. It actually does not matter whether it is true or not. As long as it sounds a bit plausible, readers will lap it up as I did. Even if it is not true, many readers would wish it to be true and somehow that makes it true for them.
Finally, the use of names from current generation of people, places gives it a look of reality. Even though the author may claim that it is a work of fiction to avoid lawsuits against him, when he starts writing about Louvre, various historical places and place of worship across Paris and London, he is asking readers to believe what he is saying. Readers would recognize the places, the pictures and their own experiences of visiting them and it becomes really hard to separate fact from fiction.
In the end, whatever he did, he wrote a great book which I have enjoyed reading. Fact or fiction is not for me to decide. In this case, unlike for other books, I even liked the movie adaptation.
