Umbridge looked quickly at Fudge, then back at Marietta.
“I don’t think you understood the question, did you, dear? I’m asking whether you’ve been going to these meetings for the past six months? You have, haven’t you?”
Again, Marietta shook her head.
“What do you mean by shaking your head, dear?” said Umbridge in a testy voice.
“I would have thought her meaning was quite clear,” said Professor McGonagall harshly, “there have been no secret meetings for the past six months. Is that correct, Miss Edgecombe?”
Marietta nodded.
“But there was a meeting tonight!” said Umbridge furiously. “There was a meeting, Miss Edgecombe, you told me about it, in the Room of Requirement! And Potter was the leader, was he not, Potter organised it, Potter—why are you shaking your head, girl?”
“Well, usually when a person shakes their head,” said McGonagall coldly, “they mean ‘no.’ So unless Miss Edgecombe is using a form of sign-language as yet unknown to humans—”
Professor Umbridge seized Marietta, pulled her round to face her and began shaking her very hard. A split second later Dumbledore was on his feet, his wand raised; Kingsley started forwards and Umbridge leapt back from Marietta, waving her hands in the air as though they had been burned.
“I cannot allow you to manhandle my students, Dolores,” said Dumbledore and, for the first time, he looked angry.
“You want to calm yourself, Madam Umbridge,” said Kingsley, in his deep, slow voice. “You don’t want to get yourself into trouble, now.”
“No,” said Umbridge breathlessly, glancing up at the towering figure of Kingsley. “I mean, yes—you’re right, Shacklebolt—I—I forgot myself.”
Marietta was standing exactly where Umbridge had released her. She seemed neither perturbed by Umbridge’s sudden attack, nor relieved by her release; she was still clutching her robe up to her oddly blank eyes and staring straight ahead of her.
A sudden suspicion, connected to Kingsley’s whisper and the thing he had felt shoot past him, sprang into Harry’s mind.
“Dolores,” said Fudge, with the air of trying to settle something once and for all, “the meeting tonight—the one we know definitely happened—”
“Yes,” said Umbridge, pulling herself together, “yes… well, Miss Edgecombe tipped me off and I proceeded at once to the seventh floor, accompanied by certain trustworthy students, so as to catch those in the meeting red-handed. It appears that they were forewarned of my arrival, however, because when we reached the seventh floor they were running in every direction. It does not matter, however. I have all their names here, Miss Parkinson ran into the Room of Requirement for me to see if they had left anything behind. We needed evidence and the room provided.”
