The Death Eater was lifted off his feet. He writhed through the air like a drowning man, thrashing and howling in pain, and then, with a crunch and a shattering of glass, he smashed into the front of a bookcase and crumpled, insensible, to the floor.
“I see what Bellatrix meant,” said Harry, the blood thundering through his brain, “you need to really mean it.”
“Potter!” whispered Professor McGonagall, clutching her heart. “Potter—you’re here! What—? How—?” She struggled to pull herself together. “Potter, that was foolish!”
“He spat at you,” said Harry.
“Potter, I—that was very—very
“Yeah, I do,” Harry assured her. Somehow her panic steadied him. “Professor McGonagall, Voldemort’s on the way.”
“Oh, are we allowed to say the name now?” asked Luna with an air of interest, pulling off the Invisibility Cloak. The appearance of a second outlaw seemed to overwhelm Professor McGonagall, who staggered backward and fell into a nearby chair, clutching at the neck of her old tartan dressing gown.
“I don’t think it makes any difference what we call him,” Harry told Luna. “He already knows where I am.”
In a distant part of Harry’s brain, that part connected to the angry, burning scar, he could see Voldemort sailing fast over the dark lake in the ghostly green boat… He had nearly reached the island where the stone basin stood…
“You must flee,” whispered Professor McGonagall, “Now, Potter, as quickly as you can!”
“I can’t,” said Harry, “There’s something I need to do. Professor, do you know where the diadem of Ravenclaw is?”
“The d-diadem of Ravenclaw? Of course not—hasn’t it been lost for centuries?” She sat up a little straighter. “Potter, it was madness, utter madness, for you to enter this castle—”
“I had to,” said Harry. “Professor, there’s something hidden here that I’m supposed to find, and it
There was a sound of movement, of clinking glass. Amycus was coming round. Before Harry or Luna could act, Professor McGonagall rose to her feet, pointed her wand at the groggy Death Eater, and said,
Amycus got up, walked over to his sister, picked up her wand, then shuffled obediently to Professor McGonagall and handed it over along with his own. Then he lay down on the floor beside Alecto. Professor McGonagall waved her wand again, and a length of shimmering silver rope appeared out of thin air and snaked around the Carrows, binding them tightly together.
“Potter,” said Professor McGonagall, turning to face him again with superb indifference to the Carrows’ predicament. “if He-Who-Must-Not-Be-Named does indeed know that you are here—”
As she said it, a wrath that was like physical pain blazed through Harry, setting his scar on fire, and for a second he looked down upon a basin whose potion had turned clear, and saw that no golden locket lay safe beneath the surface—
“Potter, are you all right?” said a voice, and Harry came back. He was clutching Luna’s shoulder to steady himself.
“Time’s running out, Voldemort’s getting nearer. Professor, I’m acting on Dumbledore’s orders, I must find what he wanted me to find! But we’ve got to get the students out while I’m searching the castle—It’s me Voldemort wants, but he won’t care about killing a few more or less, not now—”
“You’re acting on Dumbledore’s orders?” she repeated with a look of dawning wonder. Then she drew herself up to her fullest height.
“We shall secure the school against He-Who-Must-Not-Be-Named while you search for this—this object.”
“Is that possible?”
“I think so,” said Professor McGonagall dryly, “we teachers are rather good at magic, you know. I am sure we will be able to hold him off for a while if we all put our best efforts into it. Of course, something will have to be done about Professor Snape—”
“Let me—”
“—and if Hogwarts is about to enter a state of siege, with the Dark Lord at the gates, it would indeed be advisable to take as many innocent people out of the way as possible. With the Floo Network under observation, and Apparition impossible within the grounds—”
“There’s a way,” said Harry quickly, and he explained about the passageway leading into the Hog’s Head.
“Potter, we’re talking about hundreds of students—”
“I know, Professor, but if Voldemort and the Death Eaters are concentrating on the school boundaries they won’t be interested in anyone who’s Disapparating out of Hog’s Head.”
“There’s something in that,” she agreed. She pointed her wand at the Carrows, and a silver net fell upon their bound bodies, tied itself around them, and hoisted them into the air, where they dangled beneath the blue-and-gold ceiling like two large, ugly sea creatures. “Come. We must alert the other Heads of House. You’d better put that Cloak back on.”
