Yet they remained close together on the doormat, backs against the door, scared to move farther into the house.
“Well, we can’t stay here forever,” said Harry, and he took a step forward.
“Severus Snape?”
Mad-Eye Moody’s voice whispered out of the darkness, making all three of them jump back in fright. “We’re not Snape!” croaked Harry, before something whooshed over him like cold air and his tongue curled backward on itself, making it impossible to speak. Before he had time to feel inside his mouth, however, his tongue had unraveled again.
The other two seemed to have experienced the same unpleasant sensation. Ron was making retching noises; Hermione stammered, “That m-must have b-been the T-Tongue-Tying Curse Mad-Eye set up for Snape!”
Gingerly Harry took another step forward. Something shifted in the shadows at the end of the hall, and before any of them could say another word, a figure had risen up out of the carpet, tall, dust-colored, and terrible; Hermione screamed and so did Mrs. Black, her curtains flying open; the gray figure was gliding toward them, faster and faster, its waist-length hair and beard streaming behind it, its face sunken, fleshless, with empty eye sockets: Horribly familiar, dreadfully altered, it raised a wasted arm, pointing at Harry.
“No!” Harry shouted, and though he had raised his wand no spell occurred to him. “No! It wasn’t us! We didn’t kill you—”
On the word kill, the figure exploded in a great cloud of dust: Coughing, his eyes watering, Harry looked around to see Hermione crouched on the floor by the door with her arms over her head, and Ron, who was shaking from head to foot, patting her clumsily on the shoulder and saying, “It’s all r-right… It’s g-gone…”
Dust swirled around Harry like mist, catching the blue gaslight, as Mrs. Black continued to scream.
“Mudbloods, filth, stains of dishonor, taint of shame on the house of my fathers—”
“SHUT UP!” Harry bellowed, directing his wand at her, and with a bang and a burst of red sparks, the curtains swung shut again, silencing her.
“That… that was…” Hermione whimpered, as Ron helped her to her feet.
“Yeah,” said Harry, “but it wasn’t really him, was it? Just something to scare Snape.”
Had it worked, Harry wondered, or had Snape already blasted the horror-figure aside as casually as he had killed the real Dumbledore? Nerves still tingling, he led the other two up the hall, half-expecting some new terror to reveal itself, but nothing moved except for a mouse skittering along the skirting board.
“Before we go any farther, I think we’d better check,” whispered Hermione, and she raised her wand and said, “Homenum revelio.”
