The usual rash of speculation is already surrounding the new Harry Potter book, set for release next month (21 July), but now a hacker claims to have stolen a copy of the manuscript and is posting key plot details on the Web.
The hacker, known as Gabriel, says he stole a digitial copy of "Harry Potter and the Deathly Hallows" by breaking into the computer system at Bloomsbury Publishing.
The publisher has warned members of the public to be wary of people claiming to know the book's plot as there are many rumours doing the rounds.
Speculation is rife about whether Harry Potter or one of his Hogwarts school friends, Ron Weasley or Hermione Granger, are killed off in the final book.
Gabriel says in his Web posting that he is revealing the book's content in order to make it useless and boring for people to read it.
