Author JK Rowling says she is tempted to create a "director's cut" of two Harry Potter novels, because she ran out of time to finesse them.
Rowling, whose first adult novel, The Casual Vacancy, is published on Thursday, said she had deliberately taken her time to write it.
Her final Potter book, Harry Potter and the Deathly Hallows, came out in 2007.
Rowling said she wrote her latest book simply because she "wanted to".
It is aimed specifically at an older audience and includes adult themes and swear words.
