The latest Harry Potter Book, "Harry Potter and the Deathly Hallows" has been leaked on to the Internet – despite a rigorous security exercise that has shrouded the run-up to its release on Saturday.
Now, photographs of all 759 pages of the book have appeared on BitTorrent file sharing sites.
UK and US publishers are trying to stem the leak, ensuring copies of the book are removed and not republished from some site, but many international sites are outside their jurisdiction.
The last of the Harry Potter books has been eagerly awaited by fans, and surrounded by rumours about which of the main characters – if any – will be killed off.
Until today, the publishers have managed to keep on lid on so-called "spoilers", altough some bloggers have claimed to know the outcomes.
The latest, definitive, leak to the Internet has prompted fears – hopes by some – that some booksellers may start selling the book before the official deadline.
