Louise tossed and turned that night, she sat up in her four poster bed shaken with sweat. She couldn't stop thinking about Lucius Malfoy... she didn't feel safe knowing that he might still be in the school. She slipped out from the duvet and put her slippers on. She padded across the carpet to Hermione's bed.

"Hermione!" She whispered and shook her gently "I need to go and do something,".

Hermione opened her eyes and sat up slowly, she fixed Louise with a cold stare "Like what? I hope you're not going to cause any trouble,".

Louise shook her head "Of course I'm not, I just need to make sure Lucius isn't still in the school, I can't sleep, will you come with me?"

Hermione smiled. "Ok,". She got out of bed and slipped her dressing gown. She beckoned Louise to follow her. She led her into the boys dormitory where Harry and Ron were sleeping.
"Wait here,". Hermione said quietly to Louise.

Louise stood by the door nervously. She watched Hermione tip-toe towards Harry's four-poster and gently shake him awake. Harry sat up and Hermione whispered something in his ear. Harry glanced at Louise and slipped out of bed. He went to his school trunk and pulled out something that was very silvery. It was quite hard to see what is was in the dark. Louise could just about see Harry and Hermione.

Harry grinned at Louise in the dark. "This Louise is an invisibility cloak and we're gonna use this to see if Lucius is still in the school,".

Louise smiled back at Harry.

Louise joined Harry and Hermione under the invisibility cloak, her heart was beating so fast she thought she'd pass out. She gave them an encouraging smile and the 3 of them walked out of the boys dormitory and carefully stepped down the stairs. Louise thought she saw a shadow behind one of the armchairs in the common room but she ignored it. They made their way to the portrait hole and climbed through it.

"Now what?" Asked Hermione as the 3 of them stood in the deserted corridor.

"We try not to get caught,". Harry smiled "And we're gonna find Lucius,". He winked at Louise and led her and Hermione down the dark corridor.
When they had got to the end, Harry stopped and scratched his chin. He wasn't sure where to go.

"We could go to the Potions classroom,". Louise said "Him and Snape might be plotting something,". She shuddered at the thought.

"Good idea,". Harry said.

The 3 of them turned left towards the dungeons and Louise slipped her hand into Harry's and shivered. The dungeons gave her the creeps. Harry gave her a shy smile and all 3 of them slipped through the open door of the Potions classroom. There was one single candle burning on Professor Snape's desk but the classroom appeared to be deserted.
They all gave a sigh of relief and were about to turn to go when there was a sudden gust of wind and the single burning candle went out in a flash.

The invisibility cloak slipped off of them, but they didn't realise...

Louise could feel someone blowing on the back of her neck, it was warm and she shuddered. A pair of hands then grabbed her by the hair and put a piece of duck tape around her mouth to silence her muffled screams. The hands then dragged her out of the classroom and Hermione and Harry were left alone in Professor Snape's classroom.
The candle that had been blown out came alight again and this caused Hermione to grab Harry's hand.

"Ouch!" Harry pulled his hand away.

"Sssssh now Potter,". Said an oily voice from behind them. "Don't want everybody in the castle to hear you now do you?"

Harry and Hermione both turned around. Professor Snape was standing arrogantly behind his desk, his cold black eyes pierced Harry's and he smiled. "Where's your friend Louise?"

"She's here with us,". Hermione said confidently. She turned and to her surprise, no-one else was in the room. "She was with us,". She muttered under her breath, her cheeks a dark shade of magenta.

"Where is she?" Harry demanded taking his wand out. He took a step towards the laughing, greasy Professor. He loathed this man... he wanted to kill him.

"Oh she's safe... for now,". Snape laughed also taking his wand out. "Now, don't you dare challenge me Potter, you know I'd beat you any day,".

Hermione tugged the back of Harry's robe, "Please Harry no, he's a teacher,".

Harry put his wand back in his robe and turned around to leave when the same pair of hands that had grabbed Louise, smacked his face so hard that he fell to the cold stone floor...
