Dan Brown's THE LOST SYMBOL sold well over one million copies in its first 24 hours in the shops, breaking sales records for an adult fiction title. The sales - across the UK, US and Canada - were announced by the novel's American publisher Knopf. In the UK, Waterstone's* said that as well as being the fastest ever selling hard-back adult novel (the previous holder of the record was Thomas Harris for HANNIBAL) The Lost Symbol was also it's fastest selling e-book and audio download. The record-breaking sales for Brown's thriller, however are still well short of those for J.K Rowling's HARRY POTTER AND THE DEATHLY HALLOWS, which sold more than 2.6 million copies in its first 24 hours in the UK alone.
