Blue Peter

With the publication of the seventh and last Harry Potter book, Harry Potter and the Deathly Hallows, JK Rowling answers children's questions in the Blue Peter studio. In tribute to the Hogwarts Express, Gethin takes a trip on the world's most famous non-fictional steam train, the Orient Express. There's the chance to make your very own owl, and some spooky ghost-busting. Plus, there is a big surprise for JK Rowling herself, with some special messages from her celebrity fans.
