Fudge looked incredulously from Harry to Professor Umbridge. Harry took advantage of his momentary inattention to steal another quick look at Dumbledore, who gave the carpet the tiniest of nods and the shadow of a wink.
“So you have no idea,” said Fudge, in a voice positively sagging with sarcasm, “why Professor Umbridge has brought you to this office? You are not aware that you have broken any school rules?”
“School rules?” said Harry. “No.”
“Or Ministry Decrees?” amended Fudge angrily.
“Not that I’m aware of,” said Harry blandly.
His heart was still hammering very fast. It was almost worth telling these lies to watch Fudge’s blood pressure rising, but he could not see how on earth he would get away with them; if somebody had tipped off Umbridge about the D.A. then he, the leader, might as well be packing his trunk right now.
“So, it’s news to you, is it,” said Fudge, his voice now thick with anger, “that an illegal student organisation has been discovered within this school?”
“Yes, it is,” said Harry, hoisting an unconvincing look of innocent surprise on to his face.
“I think, Minister,” said Umbridge silkily from beside him, “we might make better progress if I fetch our informant.”
“Yes, yes, do,” said Fudge, nodding, and he glanced maliciously at Dumbledore as Umbridge left the room. “There’s nothing like a good witness, is there, Dumbledore?”
“Nothing at all, Cornelius,” said Dumbledore gravely, inclining his head.
There was a wait of several minutes, in which nobody looked at each other, then Harry heard the door open behind him. Umbridge moved past him into the room, gripping by the shoulder Cho’s curly-haired friend, Marietta, who was hiding her face in her hands.
“Don’t be scared, dear, don’t be frightened,” said Professor Umbridge softly, patting her on the back, “it’s quite all right, now. You have done the right thing. The Minister is very pleased with you. He’ll be telling your mother what a good girl you’ve been.”
“Marietta’s mother, Minister,” she added, looking up at Fudge, “is Madam Edgecombe from the Department of Magical Transportation, Floo Network office—she’s been helping us police the Hogwarts fires, you know.”
“Jolly good, jolly good!” said Fudge heartily. “Like mother, like daughter, eh? Well, come on, now, dear, look up, don’t be shy, let’s hear what you’ve got to—galloping gargoyles!”
As Marietta raised her head, Fudge leapt backwards in shock, nearly landing himself in the fire. He cursed, and stamped on the hem of his cloak which had started to smoke. Marietta gave a wail and pulled the neck of her robes right up to her eyes, but not before everyone had seen that her face was horribly disfigured by a series of close-set purple pustules that had spread across her nose and cheeks to form the word “SNEAK.”
“Never mind the spots now, dear,” said Umbridge impatiently, “just take your robes away from your mouth and tell the Minister—”
