London, Sep 17 (ANI): American writer Dan Brown's new book 'The Lost Symbol' is said to have broken sales record in the first 36 hours of its release in the UK, after it sold more copies than any other adult hardback novel.
The book, which went on sale on September 15, has sold more than 300,000 copies in the UK.
The previous best-selling adult hardback was Thomas Harris' 'Hannibal', which has sold 298,000 copies since it was published in 1999.
'The Lost Symbol' once again features Harvard symbologist Robert Langdon from 'The Da Vinci Code', and had a UK first print run of a million.
According to Publisher Transworld, the book has sold more than 1million copies worldwide.
Transworld warned it was on the lookout for websites offering pirated copies of the new novel, after reports that two sites had already posted material from the book.
"We have a very vigilant team who are constantly scanning the web to investigate potential piracy issues," the BBC quoted a spokeswoman as saying.
"If and when they do find any rogue material out there we will issue 'take down' notices," she added. (ANI)
