He skidded around another corner and a curse flew past him; he dived behind a suit of armor that exploded. He saw the brother and sister running down the marble staircase ahead and aimed jinxes at them, but merely hit several bewigged witches in a portrait on the landing, who ran screeching into neighboring paintings. As he leapt the wreckage of armor, Harry heard more shouts and screams; other people within the castle seemed to have awoken…
He pelted toward a shortcut, hoping to overtake the brother and sister and close in on Snape and Malfoy, who must surely have reached the grounds by now. Remembering to leap the vanishing step halfway down the concealed staircase, he burst through a tapestry at the bottom and out into a corridor where a number of bewildered and pajama-clad Hufflepuffs stood.
“Harry! We heard a noise, and someone said something about the Dark Mark—” began Ernie Macmillan.
“Out of the way!” yelled Harry, knocking two boys aside as he sprinted toward the landing and down the remainder of the marble staircase. The oak front doors had been blasted open, there were smears of blood on the flagstones, and several terrified students stood huddled against the walls, one or two still cowering with their arms over their faces. The giant Gryffindor hourglass had been hit by a curse, and the rubies within were still falling, with a loud rattle, onto the flagstones below.
Harry flew across the entrance hall and out into the dark grounds: He could just make out three figures racing across the lawn, heading for the gates beyond which they could Disapparate—by the looks of them, the huge blond Death Eater and, some way ahead of him, Snape and Malfoy…
The cold night air ripped at Harry’s lungs as he tore after them; he saw a flash of light in the distance that momentarily silhouetted his quarry. He did not know what it was but continued to run, not yet near enough to get a good aim with a curse—
Another flash, shouts, retaliatory jets of light, and Harry understood: Hagrid had emerged from his cabin and was trying to stop the Death Eaters escaping, and though every breath seemed to shred his lungs and the stitch in his chest was like fire, Harry sped up as an unbidden voice in his head said: not Hagrid… not Hagrid too…
Something caught Harry hard in the small of the back and he fell forward, his face smacking the ground, blood pouring out of both nostrils: He knew, even as he rolled over, his wand ready, that the brother and sister he had overtaken using his shortcut were closing in behind him…
“Impedimenta!” he yelled as he rolled over again, crouching close to the dark ground, and miraculously his jinx hit one of them, who stumbled and fell, tripping up the other; Harry leapt to his feet and sprinted on after Snape.
And now he saw the vast outline of Hagrid, illuminated by the light of the crescent moon revealed suddenly behind clouds; the blond Death Eater was aiming curse after curse at the gamekeeper; but Hagrid’s immense strength and the toughened skin he had inherited from his giantess mother seemed to be protecting him. Snape and Malfoy, however, were still running; they would soon be beyond the gates, able to Disapparate—
Harry tore past Hagrid and his opponent, took aim at Snape’s back, and yelled, “Stupefy!”
He missed; the jet of red light soared past Snape’s head; Snape shouted, “Run, Draco!” and turned. Twenty yards apart, he and Harry looked at each other before raising their wands simultaneously.
“Cruc—”
But Snape parried the curse, knocking Harry backward off his feet before he could complete it; Harry rolled over and scrambled back up again as the huge Death Eater behind him yelled, “Incendio!” Harry heard an explosive bang and a dancing orange light spilled over all of them: Hagrid’s house was on fire.
“Fang’s in there, yer evil—!” Hagrid bellowed.
“Cruc—” yelled Harry for the second time, aiming for the figure ahead illuminated in the dancing firelight, but Snape blocked the spell again. Harry could see him sneering.
“No Unforgivable Curses from you, Potter!” he shouted over the rushing of the flames, Hagrid’s yells, and the wild yelping of the trapped Fang. “You haven’t got the nerve or the ability—”
“Incarc—” Harry roared, but Snape deflected the spell with an almost lazy flick of his arm.
“Fight back!” Harry screamed at him. “Fight back, you cowardly—”
“Coward, did you call me, Potter?” shouted Snape. “Your father would never attack me unless it was four on one, what would you call him, I wonder?”
“Stupe—”
“Blocked again and again and again until you learn to keep your mouth shut and your mind closed, Potter!” sneered Snape, deflecting the curse once more. “Now come!” he shouted at the huge Death Eater behind Harry. “It is time to be gone, before the Ministry turns up—”
“Impedi—”
But before he could finish this jinx, excruciating pain hit Harry; he keeled over in the grass. Someone was screaming, he would surely die of this agony, Snape was going to torture him to death or madness—
“No!” roared Snape’s voice and the pain stopped as suddenly as it had started; Harry lay curled on the dark grass, clutching his wand and panting; somewhere overhead Snape was shouting, “Have you forgotten our orders? Potter belongs to the Dark Lord—we are to leave him! Go! Go!”
And Harry felt the ground shudder under his face as the brother and sister and the enormous Death Eater obeyed, running toward the gates. Harry uttered an inarticulate yell of rage: In that instant, he cared not whether he lived or died. Pushing himself to his feet again, he staggered blindly toward Snape, the man he now hated as much as he hated Voldemort himself—
“Sectum—”
Snape flicked his wand and the curse was repelled yet again; but Harry was mere feet away now and he could see Snape’s face clearly at last: He was no longer sneering or jeering; the blazing flames showed a face full of rage. Mustering all his powers of concentration, Harry thought, Levi—
“No, Potter!” screamed Snape. There was a loud BANG and Harry was soaring backward, hitting the ground hard again, and this time his wand flew out of his hand. He could hear Hagrid yelling and Fang howling as Snape closed in and looked down on him where he lay, wandless and defenseless as Dumbledore had been. Snape’s pale face, illuminated by the flaming cabin, was suffused with hatred just as it had been before he had cursed Dumbledore.
“You dare use my own spells against me, Potter? It was I who invented them—I, the Half-Blood Prince! And you’d turn my inventions on me, like your filthy father, would you? I don’t think so… no—”
Harry had dived for his wand; Snape shot a hex at it and it flew feet away into the darkness and out of sight.
“Kill me then,” panted Harry, who felt no fear at all, but only rage and contempt. “Kill me like you killed him, you coward—”
“DON’T—” screamed Snape, and his face was suddenly demented, inhuman, as though he was in as much pain as the yelping, howling dog stuck in the burning house behind them, “—CALL ME COWARD!”
And he slashed at the air: Harry felt a white-hot, whiplike something hit him across the face and was slammed backward into the ground. Spots of light burst in front of his eyes and for a moment all the breath seemed to have gone from his body, then he heard a rush of wings above him and something enormous obscured the stars. Buckbeak had flown at Snape, who staggered backward as the razor-sharp claws slashed at him. As Harry raised himself into a sitting position, his head still swimming from its last contact with the ground, he saw Snape running as hard as he could, the enormous beast flapping behind him and screeching as Harry had never heard him screech—
Harry struggled to his feet, looking around groggily for his wand, hoping to give chase again, but even as his fingers fumbled in the grass, discarding twigs, he knew it would be too late, and sure enough, by the time he had located his wand, he turned only to see the hippogriff circling the gates. Snape had managed to Disapparate just beyond the school’s boundaries.
