In the meantime, Harry and McGonagall were in hot pursuit of the killer. They followed the trail all over the school.
"Mwah ha ha ha ha!!!!" echoed a voice. Professor McGonagall pulled on the back of Harry's shirt. "Do not move a muscle," she said.
Sure enough, they could see a shadow rising. It looked like it was a person. They were cackling and some liquid was dripping off of their hands. They licked the liquid off of their hands and disappeared.
"What was THAT?" asked Harry.
"It was more than likely the killer," said Professor McGonagall. "Come on, we need to trap it and I've got a plan."
Ron and Cho slowly exited the broom closet and made their way back to the Great Hall.
"Hello... anybody in here?" said Ron, opening the door to the Great Hall.
"You are such an idiot, Ron!" shouted Cho. "Do you want to lead the killer right to us or what? Anyway, I need to find a bathroom. Thanks to your horrible making out skills, my lipstick is all smudged and I must reapply it."
The two of them made their way down the hall, when something caught their eye. It was Professor Trelawney, surrounded by a great red pool of blood!
Ron ran over immediately. "Professor Trelawney! Cho, she's dead! Surrounded by all her sweet-smelling blood. Mmmm, blood."
"Don't go all vampire on me now, Ron," said Cho, carefully making her way to Trelawney, trying not to stain her dress. "You should have got all that neck-biting out of your system by now, you certainly bit me enough."
Cho bent down to inspect the blood. "You idiot! This isn't blood at all! It's sherry. Trelawney was obviously drunk on sherry, broke her bottle, and left this red trail behind her."
Ron looked rather sheepishly at her. But suddenly, a very loud noise was coming for them.
It looked like... Fluffy!
