The liquid in the cauldron seemed to heat very fast. The surface began not only to bubble, but to send out fiery sparks, as though it were on fire. Steam was thickening, blurring the outline of Wormtail tending the fire. The movements beneath the robes became more agitated. And Harry heard the high, cold voice again.
The whole surface of the water was alight with sparks now. It might have been encrusted with diamonds.
“It is ready. Master.”
Wormtail pulled open the robes on the ground, revealing what was inside them, and Harry let out a yell that was strangled in the wad of material blocking his mouth.
It was as though Wormtail had flipped over a stone and revealed something ugly, slimy, and blind—but worse, a hundred times worse. The thing Wormtail had been carrying had the shape of a crouched human child, except that Harry had never seen anything less like a child. It was hairless and scaly looking, a dark, raw, reddish black. Its arms and legs were thin and feeble, and its face—no child alive ever had a face like that—flat and snakelike, with gleaming red eyes.
The thing seemed almost helpless; it raised its thin arms, put them around Wormtail’s neck, and Wormtail lifted it. As he did so, his hood fell back, and Harry saw the look of revulsion on Wormtail’s weak, pale face in the firelight as he carried the creature to the rim of the cauldron. For one moment, Harry saw the evil, flat face illuminated in the sparks dancing on the surface of the potion. And then Wormtail lowered the creature into the cauldron; there was a hiss, and it vanished below the surface; Harry heard its frail body hit the bottom with a soft thud.
Wormtail was speaking. His voice shook; he seemed frightened beyond his wits. He raised his wand, closed his eyes, and spoke to the night.
The surface of the grave at Harry’s feet cracked. Horrified, Harry watched as a fine trickle of dust rose into the air at Wormtail’s command and fell softly into the cauldron. The diamond surface of the water broke and hissed; it sent sparks in all directions and turned a vivid, poisonous looking blue.
And now Wormtail was whimpering. He pulled a long, thin, shining silver dagger from inside his cloak. His voice broke into petrified sobs.
He stretched his right hand out in front of him—the hand with the missing finger. He gripped the dagger very tightly in his left hand and swung it upward.
Harry realized what Wormtail was about to do a second before it happened—he closed his eyes as tightly as he could, but he could not block the scream that pierced the night, that went through Harry as though he had been stabbed with the dagger too. He heard something fall to the ground, heard Wormtail’s anguished panting, then a sickening splash, as something was dropped into the cauldron. Harry couldn’t stand to look… but the potion had turned a burning red; the light of it shone through Harry’s closed eyelids…
Wormtail was gasping and moaning with agony. Not until Harry felt Wormtail’s anguished breath on his face did he realize that Wormtail was right in front of him.
Harry could do nothing to prevent it, he was tied too tightly… Squinting down, struggling hopelessly at the ropes binding him, he saw the shining silver dagger shaking in Wormtails remaining hand. He felt its point penetrate the crook of his right arm and blood seeping down the sleeve of his torn robes. Wormtail, still panting with pain, rumbled in his pocket for a glass vial and held it to Harry’s cut, so that a dribble of blood fell into it.
He staggered back to the cauldron with Harry’s blood. He poured it inside. The liquid within turned, instantly, a blinding white. Wormtail, his job done, dropped to his knees beside the cauldron, then slumped sideways and lay on the ground, cradling the bleeding stump of his arm, gasping and sobbing.
The cauldron was simmering, sending its diamond sparks in all directions, so blindingly bright that it turned all else to velvety blackness. Nothing happened…
