Harry Potter has not had a good summer. Not only has he had to put up with his overbearing Aunt Petunia and Uncle Vernon Dursley and their dread of his magical abilities, but it seems as if Harry’s best friends Ron Weasley and Hermione Granger have forgotten him – as they haven’t replied to a single one of his letters. Then, suddenly and mysteriously, house-elf Dobby appears in Harry’s bedroom and warns of great danger if the aspiring wizard should attempt to return to Hogwarts. Dobby is so keen to prevent the young Gryffindor from returning to the school for witches and wizards, he has blocked all of Ron and Hermione’s correspondence from reaching Harry. But despite the elf’s mischievous efforts, the ever-determined Harry is rescued from the Dursleys’ dreary clutches by Ron and his brothers – with the aid of a flying car! – and welcomed into the warmth of the Weasley household.
