"Claire! Claire! Look what I found!" said an excited and flustered third year. She was running down the corridor towards another third year with a piece of parchment clutched in her hand.
Claire stopped in the middle of the hallway and waited for the girl.
"Addy? What is it?"
"I found it in the Come-and-Go room. I asked for something that would help me snuck into the kitchens and help without pranks! The room was completely empty except for this." she said, thrusting a piece of parchment at her friend. Written across the front was the words 'Mischief Managed.'
As soon as Claire grabbed it and both girls were holding it, the message disappeared and longer inscription took its place.
"Bloody Hell!" muttered Addy.
Claire examined the piece of parchment and hesitantly place her wand under the inscription and read it out loud.
"I solemnly swear that I am up to no good."
The message disappeared and a welcome took its place. She opened the parchment and a slow devious grin spread across her face.
"Oh Addy." she said. "We are going to have a lot of fun with this."
She turned it around to show her the map that showed them everyone and everywhere in Hogwarts.
Claire closed the map and after a moment's thought, spoke with her wand pointed at the map.
"Mischief Managed."
