Harry Potter and the Order of the Phoenix (novel)/Recap/C01 Dudley Demented
Harry Potter is hanging out on a summers day - under his uncle's sitting room window. He's listening for news of recent murders, because Lord Voldemort is once again alive. He leaves but meets his piggish cousin Dudley, who proceeds to insult Harry. Harry threatens Dudley with his wand, and Dementors show up. Chaos ensues as Dudley nearly loses his soul and is reduced to gibbering temporary insanity. And who should arrive to rescue the duo but Mrs. Figg, the elderly neighbour who just happens to be Squib and friend of Dumbldore.
