Eventually, Dumbledore straightened up. "She's not dead, Argus."
Lockhart went silent, while Filch stared at Mrs Norris. "Not dead? But why's she all, all stiff and frozen?"
"She has been Petrified." Dumbledore replied. ("Ah! I thought so!" said Lockhart) "But how, I cannot say..."
"Ask him!" Filch shrieked, turning towards Draco, who shrank back.
"No second-year could have done this." Dumbledore said firmly. "It would take Dark Magic of the most advanced-"
"He did it, he did it!" Filch spat, his face purpling with rage. "You saw what he wrote on the wall! The Malfoys know Dark Magic, all of them! He did it! He knows how!"
"Watch your words, Filch." Snape whispered horribly from his position in the shadows. "I do not condone attacks on those under my charge, especially if there's no proof."
The two most hated men in Hogwarts glared at each other.
