"Harry," the old wizard said from behind the desk, the aged voice level as the blue eyes stared out at him from beneath the shining half-moon spectacles. Headmaster Dumbledore had garbed himself in robes of midnight purple; not true formal black, but dark enough to come close indeed to deadly seriousness, as the wizarding world counted the meaning of fashions. "Were you... responsible for this?"
"I cannot deny that my influence was at work," Harry said.
The old wizard took off his glasses, leaned forward to stare at Harry directly, blue eyes to green. "I will ask you one question," the Headmaster said in a quiet voice. "Do you think that what you did today was - appropriate?"
"They were bullies and they came to that hallway with the direct intent of hurting Hermione Granger and seven other first-year children," Harry said levelly. "If I am not too young for moral judgment, then neither are they. No, Headmaster, they didn't deserve to die. But they did deserve to be stripped naked and glued to the ceiling."
The old wizard put his glasses back on. For the first time that Harry had seen of him, the Headmaster seemed to be at a loss for words. "As Merlin himself is my witness," said Dumbledore, "I haven't the faintest notion of how I ought to react to this."
"That's pretty much the effect I was aiming for," said Harry. He felt like he ought to be whistling a merry tune, but unfortunately he had never learned how to whistle reliably.
