“Mad, am I?” said Moody, his voice rising uncontrollably. “We’ll see! We’ll see who’s mad, now that the Dark Lord has returned, with me at his side! He is back, Harry Potter, you did not conquer him—and now—I conquer you!”

Moody raised his wand, he opened his mouth; Harry plunged his own hand into his robes—

“Stupefy!” There was a blinding flash of red light, and with a great splintering and crashing, the door of Moody’s office was blasted apart—

Moody was thrown backward onto the office floor. Harry, still staring at the place where Moody’s face had been, saw Albus Dumbledore, Professor Snape, and Professor McGonagall looking back at him out of the Foe-Glass. He looked around and saw the three of them standing in the doorway, Dumbledore in front, his wand outstretched.

At that moment, Harry fully understood for the first time why people said Dumbledore was the only wizard Voldemort had ever feared. The look upon Dumbledore’s face as he stared down at the unconscious form of Mad-Eye Moody was more terrible than Harry could have ever imagined. There was no benign smile upon Dumbledore’s face, no twinkle in the eyes behind the spectacles. There was cold fury in every line of the ancient face; a sense of power radiated from Dumbledore as though he were giving off burning heat.

He stepped into the office, placed a foot underneath Moody’s unconscious body, and kicked him over onto his back, so that his face was visible. Snape followed him, looking into the Foe-Glass, where his own face was still visible, glaring into the room. Professor McGonagall went straight to Harry.

“Come along, Potter,” she whispered. The thin line of her mouth was twitching as though she was about to cry. “Come along . . . hospital wing . . . ”

“No,” said Dumbledore sharply.

“Dumbledore, he ought to—look at him—he’s been through enough tonight—”

“He will stay, Minerva, because he needs to understand,” said Dumbledore curtly. “Understanding is the first step to acceptance, and only with acceptance can there be recovery. He needs to know who has put him through the ordeal he has suffered tonight, and why.”

“Moody,” Harry said. He was still in a state of complete disbelief. “How can it have been Moody?”

“This is not Alastor Moody,” said Dumbledore quietly. “You have never known Alastor Moody. The real Moody would not have removed you from my sight after what happened tonight. The moment he took you, I knew—and I followed.”

Dumbledore bent down over Moody’s limp form and put a hand inside his robes. He pulled out Moody’s hip flask and a set of keys on a ring. Then he turned to Professors McGonagall and Snape.
