“Keep your fat mouth shut, then,” said Harry, turning away.
BANG!
Several people screamed—Harry felt something white hot graze the side of his face—he plunged his hand into his robes for his wand, but before he’d even touched it, he heard a second loud BANG, and a roar that echoed through the entrance hall.
“OH NO YOU DON’T, LADDIE!”
Harry spun around. Professor Moody was limping down the marble staircase. His wand was out and it was pointing right at a pure white ferret, which was shivering on the stone flagged floor, exactly where Malfoy had been standing.
There was a terrified silence in the entrance hall. Nobody but Moody was moving a muscle. Moody turned to look at Harry—at least, his normal eye was looking at Harry; the other one was pointing into the back of his head.
“Did he get you?” Moody growled. His voice was low and gravelly.
“No,” said Harry, “missed.”
“LEAVE IT!” Moody shouted.
“Leave—what?” Harry said, bewildered.
“Not you—him!” Moody growled, jerking his thumb over his shoulder at Crabbe, who had just frozen, about to pick up the white ferret. It seemed that Moody’s rolling eye was magical and could see out of the back of his head.
Moody started to limp toward Crabbe, Goyle, and the ferret, which gave a terrified squeak and took off, streaking toward the dungeons.
“I don’t think so!” roared Moody, pointing his wand at the ferret again—it flew ten feet into the air, fell with a smack to the floor, and then bounced upward once more.
“I don’t like people who attack when their opponent’s back’s turned,” growled Moody as the ferret bounced higher and higher, squealing in pain. “Stinking, cowardly, scummy thing to do…” The ferret flew through the air, its legs and tail flailing helplessly.
“Never—do—that—again—” said Moody, speaking each word as the ferret hit the stone floor and bounced upward again.
