Harry Potter and the Runaway Convict
Chapter 24

Smiles spread across the faces of Fred, George, Ginny, Bill, Charlie, Percy, Arthur and Ron Weasley, Albus Dumbledore, Minerva McGonagall, Remus Lupin, Kristin Waters, Julie Montgomery, even Severus Snape, but most of all, Harry Potter and Sirius Black.
Just as Judge DeRosa had been declaring Sirius guilty, the door had been thrown open, and no one had ever been happier to see Melissa Gumtree, rat in tow.
"I have proof that Sirius Black is innocent, your honor, and it comes in the form of this." She thrust the rat towards the judge.
"Young lady, that is a rat you hold there in your hands. Why is that rat going to make Sirius Black
"This is no rat, your honor. This is an Animagus by the name of Peter Pettigrew. She stuck her wand at the rat, murmured something, and it transformed into a short, balding man.
"Peter!" Morgan shrieked, and she tried to run at her husband, but was blocked by the Judge, who was carefully examining Peter Pettigrew.
"Severus, you brought the Veritaserum as I asked, did you not?" Judge DeRosa asked.
"Of course, your honor," Snape said, and he handed the Judge a vile that contained a potion it it.
"Are you going to question Pettigrew?" Snape asked.
"First, I intend on finding out if this man here truly is Peter Pettigrew, and then yes, I will question him and Black both. Young lady, if this rat is who you say, and he tells us the same thing that Mr. Black has just told us, then you may have just stopped me from making the biggest mistake of my entire life, and mor eimportantly, saved an innocent man. Thank you," he said.
"You're welcome," she said.
"Not yet, I'm not. Wait until we have finished the questioning."
"Yes, sir," she said.
"Court is now back in order, and I have at the stand Sirius Black and Peter Pettigrew, both under the influence of the strongest truth potion known to wizards- Veritaserum. Proceed."
