As she walked down the corridor on the seventh floor, beside herself with fury, Umbridge was glaring at nothing in particular. In her fist, she was clutching a copy of a rubbish paper called the Quibbler. She ground her teeth in anger; how dare that boy be spreading his filthy lies publicly! She had thought that after quite a few detentions with her blood quill, he would have given up and abandoned his lies, but now! In fact, far from discouraging him, she thought it might have even encouraged him! She began pacing the deserted corridor, walking back and forth, trying to think of a way to discredit him. What she really needed, she thought, was access to the truth. She needed a full proof way for everyone to find out what a nasty little lying attention seeking brat he was. She needed-
A door suddenly appeared on the wall next to her as she passed the same spot for the third time. Mouth hanging open, she stared at the door in shock. She was sure the door hadn't been there a moment ago. Had she, perhaps, discovered some long lost Hogwarts secret? She opened the door, only to feel immense disappointment. It was only a small cupboard, most likely for storage. It was nearly empty, accept for a pile of dusty books in the corner. Long lost Hogwarts secret indeed, she scoffed, turning away; when suddenly the title of the top book seemed to flash, as if trying to get her attention. Harry Potter and the Sorcerer's Stone.
Ever so slowly, Umbridge approached the pile of books. Looking closer, her lips curved up into a nasty grin as she examined the seven books. This was exactly the type of thing she had been looking for. It was as if the room had appeared just for her... it was as if it was created for the purpose of serving her.
Tossing the Quibbler to the floor, she picked up the books with a quick flick of her wand, smiling cruelly to herself. The brat Potter was going to get what was coming to him.
"Surely you don't mean to let her go through with this, Headmaster!" Professor McGonagall looked furious.
"I'm afraid," said Dumbledore, "That I have no say in the matter."
"But-But-" McGonagall spluttered, "But Potter! At least say he doesn't have to hear it! He's been through too much already; would you be so cruel as to force him to live through it again?"
Dumbledore lowered his head sadly and nodded. "I couldn't agree with you more... however, Dolores has ordered that everyone be in the Great Hall at eight o' clock tomorrow morning. I have a feeling she won't show Harry any kindness whatsoever. She will glory at the pain this will put him through, and she would sooner marry a muggle than spare him this agony."
"But Headmaster, he doesn't even know what she is planning! What a horrible thing to wake up to, hearing that books of your life we're going to be read aloud to the entire school! At least warn him, let him prepare himself mentally, let him seek comfort from his friends!"
Dumbledore shook his head. "Dolores made it quite clear that nobody at Hogwarts but the staff should know… but," he said, before the Gryffindor head of house could protest, "I think we could help, perhaps, by bringing in a few people who would support Harry." He lifted his head, and Minerva was surprised to see that his eyes were moist. "If you would, Minerva, send an owl to a few of Potter's close friends."
"The Weasleys, and Lupin definitely," she said, trying to name the people she knew cared about Harry very much. "Tonks and Mad Eye…"
"And Sirius." said Dumbledore.
"Do be reasonable, Dumbledore," she said, "You know Black can't come to Hogwarts; not with all those Ministry workers Dolores invited."
"I think," he said politely, "That Sirius may be one of the only people who will truly be able to help Harry cope with this. I know Sirius would most definitely not want to miss this… he should be safe if he agrees to come in his animagus form, at least until the books prove him innocent."
McGonagall nodded, slightly reluctantly, being worried for Black's safety. "I'll see to it that those owls are sent, Headmaster."
"Harry? Harry! HARRY!"
Harry Potter sat bolt upright in his bed up in Gryffindor Tower. He was sweating profusely, and shaking uncontrollably.
