Dan Brown talks writing

NBC's Today show had an exclusive interview with Dan Brown yesterday to celebrate the publishing of The Lost Symbol. Matt Lauer, the host, got a tour of the writer's home in New Hampshire. Fans learned that:

• Brown's best time of the day to write is 4 am.
• The Lost Symbol took six years to complete because of the pressure of repeating the Da Vinci Code success and because Freemasonry was so complex.
• Brown's fame gives him access to places other people rarely see.
• He sometimes goes undercover to research his books by joining a tour group, wearing a baseball cap.
• Brown has become more spiritual in recent years.
• He admires the Freemasons because they allow people of all faiths to come together.
• He chose Washington, DC, as the setting for The Lost Symbol because he believes its architecture is as interesting as that of London, Paris and Rome.
