This is the fifth Harry Potter book by J.K. Rowling and in this book, Harry resorts, to hiding outside to listen to the news on T.V. As he is desperate to find out what is being done about Voldermort. He also feels he is being left in the dark and he guesses rightly that Ron and Hermione are together while he is stuck, in Privet drive.
There is a loud pop which startles Vernon and Petunia Dursley and they then discover where Harry was hiding and so he had to leave.
Then later on Harry is sitting on a swing in a park when Dudley comes up and taunts him. Dudley then realizes that something is happening, but he mistakenly thinks that Harry is doing magic.
Dudley then feels extremely scared and turns to run away, and Harry had to save his cousin from the Dementors. Also, Harry is feeling confused, as it seems that the headmaster Albus Dumbledore is distancing himself from him..
