At eleven o’clock that night, they said good bye to Ron in the common room and went down to the entrance hall with Neville. Filch was already there—and so was Malfoy. Harry had also forgotten that Malfoy had gotten a detention, too.

“Follow me,” said Filch, lighting a lamp and leading them outside.

“I bet you’ll think twice about breaking a school rule again, won’t you, eh?” he said, leering at them. “Oh yes... hard work and pain are the best teachers if you ask me... It’s just a pity they let the old punishments die out... hang you by your wrists from the ceiling for a few days, I’ve got the chains still in my office, keep ’em well oiled in case they’re ever needed... Right, off we go, and don’t think of running off, now, it’ll be worse for you if you do.”

They marched off across the dark grounds. Neville kept sniffing. Harry wondered what their punishment was going to be. It must be something really horrible, or Filch wouldn’t be sounding so delighted.

The moon was bright, but clouds scudding across it kept throwing them into darkness. Ahead, Harry could see the lighted windows of Hagrid’s hut. Then they heard a distant shout.
