Everyone was looking around. "Oh my God we're all going to die!" shouted Draco Malfoy. McGonagall looked at him and raised her eyebrows.

"You all were here," said Hermione Granger, "you all had motive. Somebody in this room killed Percy Weasley." Everyone looked from person to person.

"I know who did it!" said Harry. "It was Snape!" Everyone rolled their eyes. "No really! It has to be! I heard him muttering incantations! He killed Percy Weasley!"

Professor Snape turned around. Maybe it was because he was used to Harry blaming him every time anything went wrong, but he didn't look that upset. "How many times have you accused me of various forms of murder and foul play, Mr. Potter?" he said. "Hmm? And how many of those times have you been correct?"

"You are so lucky to have me with you for dinner!" exclaimed Professor Trelawney. "I have the INNER EYE, and I will be able to use my powers to tell you exactly who killed Percy Weasley." She closed her eyes and placed her fingers to her temples, chanting strangely. "Emmm, emmm, emmm.... Yes! It was Colonel Mustard in the Conservatory with the Wrench!"

Everyone looked at her skeptically. "Umm, that was just a practice," she said, "I'm getting it, I'm getting it. Oh! Of course! Why hadn't I thought of this before! It was.... THE GRIM!"

This time people groaned out loud without concern for Professor Trelawney's ego. "Now now!" said Professor Dumbledore. "Miss Granger is right. Someone killed young Percy Weasley. I would like everyone to follow me to my office. Nobody will be allowed to leave until we can figure out the culprit."

Everyone left the Great Hall and went up to Dumbledore's office.

"Professor Snape, would you fetch me the Veritaserum," said Professor Dumbledore. "Now, I expect one of you know what Veritaserum is used for."

"I do, Professor!" said Hermione Granger, her hand waving wildly. "Veritaserum, also known as Truth Potion, when drank will force the drinker to be completely truthful and to answer every question honestly. It is a very powerful potion strict guidelines for its use have been set by the Ministry of Magic."

"Very good, Miss Granger!" said Dumbledore. "A billion points to Gryffindor!"

Professor McGonagall looked at him skeptically.

"Isn't this Who's Line is it Anyway? Where everything is made up and the points don't matter?" McGonagall shook her head. "Oh," said Professor Dumbledore, "well, make it 10 points then."

Just then, Professor Snape returned with the bottle. "Shall we begin the interrogations then?" she said.

"Certainly, Professor Snape," said Dumbledore. "Before you speak, I would like you to take some Veritaserum. Let the interrogations begin! We'll start with you Mr. Potter."
