From this Saturday millions of people around the world will finally discover the secrets of the seventh and last Harry Potter book, marking the final chapter in an extraordinary publishing phenomenon.
Extra barbed wire was installed around the Suffolk printworks and guards have been put on the doors, as speculation mounts about how the Harry Potter series will end.
Security arrangements have been stepped up at the Clay’s in Bungay, printers of the final instalment in the series; Harry Potter and the Deathly Hallows, which will be published at one minute past midnight on July 21 – it is already the most ordered book in history.
Staff have also had to face restrictions – most are not allowed to take mobile phones into work in case they use a camera phone to take pictures. They can only take a small bag into work, which has to be searched. They also need identification to get into the building, and have signed a contract banning them from talking about the book. And workers who normally scan-read the books for errors as they are being printed have been banned from doing so in case the secrets leak out.
