Harry has yet again spent the summer holidays at the Dursleys'. He has had plenty to think about, though - from the death of his beloved godfather Sirius Black, to the terrifying chase through the Ministry of Magic by the Death Eaters, to the fierce duel he witnessed between Professor Dumbledore and Lord Voldemort. It is the middle of the summer, but there is an unseasonal mist pressing against the windowpanes. Harry is waiting nervously for a visit from Professor Dumbledore himself. He can't quite believe that Professor Dumbledore will actually appear at the Dursleys' of all places.
