Hidden away on Dan Brown's newly designed website is an 'easter egg' - a link to the very first line of his new book The Lost Symbol.

**Spoiler alert: avert your eyes if you don't want the answer**

For those that do want to know the answer, it can be found by going to the section on The Da Vinci Code, selecting 'Resources', clicking on the link to the "Reader's Guide", and then scrolling to the bottom of that page. There you'll find a symbol, if you click on that it takes you to the 'reveal'. The first line of the book is "The secret is how to die." Not exactly a giveaway of the plot, but certainly a tantalising start!
