He gestured at his massive chest. Harry understood. Dudley was remembering the clammy cold that filled the lungs as hope and happiness were sucked out of you.
“Horrible,” croaked Dudley. “Cold. Really cold.”
“OK,” said Uncle Vernon, in a voice of forced calm, while Aunt Petunia laid an anxious hand on Dudley’s forehead to feel his temperature. “What happened then, Dudders?”
“Felt… felt… felt… as if… as if…”
“As if you’d never be happy again,” Harry supplied dully.
“Yes,” Dudley whispered, still trembling.
“So!” said Uncle Vernon, voice restored to full and considerable volume as he straightened up. “You put some crackpot spell on my son so he’d hear voices and believe he was—was doomed to misery, or something, did you?”
“How many times do I have to tell you?” said Harry, temper and voice both rising.
“A couple of—what’s this codswallop?”
“De—men—tors,” said Harry slowly and clearly. “Two of them.”
“And what the ruddy hell are Dementors?”
“They guard the wizard prison, Azkaban,” said Aunt Petunia.
Two seconds of ringing silence followed these words before Aunt Petunia clapped her hand over her mouth as though she had let slip a disgusting swear word. Uncle Vernon was goggling at her. Harry’s brain reeled. Mrs. Figg was one thing—but
“How d’you know that?” he asked her, astonished.
Aunt Petunia looked quite appalled with herself. She glanced at Uncle Vernon in fearful apology, then lowered her hand slightly to reveal her horsy teeth.
“I heard—that awful boy—telling
“If you mean my mum and dad, why don’t you use their names?” said Harry loudly, but Aunt Petunia ignored him. She seemed horribly flustered.
Harry was stunned. Except for one outburst years ago, in the course of which Aunt Petunia had screamed that Harry’s mother had been a freak, he had never heard her mention her sister. He was astounded that she had remembered this scrap of information about the magical world for so long, when she usually put all her energies into pretending it didn’t exist.
Uncle Vernon opened his mouth, closed it again, opened it once more, shut it, then, apparently struggling to remember how to talk, opened it for a third time and croaked, “So—so—they—er—they—er—they actually exist, do they—er—Dementy-whatsits?”
Aunt Petunia nodded.
Uncle Vernon looked from Aunt Petunia to Dudley to Harry as if hoping somebody was going to shout “April Fool!” When nobody did, he opened his mouth yet again, but was spared the struggle to find more words by the arrival of the third owl of the evening. It zoomed through the still-open window like a feathery cannon-ball and landed with a clatter on the kitchen table, causing all three of the Dursleys to jump with fright. Harry tore a second official-looking envelope from the owls beak and ripped it open as the owl swooped back out into the night.
“Enough—effing—owls,” muttered Uncle Vernon distractedly, stomping over to the window and slamming it shut again.
Harry read this letter through three times in quick succession. The miserable knot in his chest loosened slightly with the relief of knowing he was not yet definitely expelled, though his fears were by no means banished. Everything seemed to hang on this hearing on the twelfth of August.
“Well?” said Uncle Vernon, recalling Harry to his surroundings. “What now? Have they sentenced you to anything? Do your lot have the death penalty?” he added as a hopeful afterthought.
“I’ve got to go to a hearing,” said Harry.
“And they’ll sentence you there?”
“I suppose so.”
“I won’t give up hope, then,” said Uncle Vernon nastily.
