LONDON (Reuters) - Dan Brown's follow-up novel to his global bestseller "The Da Vinci Code" won't be ready by the end of the year as originally expected, his publisher said on Friday.
"We don't know when it's coming, but it's out of the schedule for this year," said Larry Finlay, managing director for Transworld Publishers in London, a division of Bertelsmann-owned Random House.
"At one point we were hoping for it around October or November, but now it's looking like 2007," he told Reuters, confirming a report in the Bookseller trade publication.

Hmm, perhaps the delay is because of the Kryptos announcement? Brown has to rewrite the Kryptos section now... ;)
