A/N: Sorry about the late update, but the internet was down so I'd written the chapter but couldn't post it! :/

Had another day off school because of the electrics again. They went off at the beginning of the day so we could go home before lunch haha!

If you guys have any ideas for the story, then please let me know! I do have a storyline, but it's so rough you can't really call it a 'storyline'... more of an idea ;)

"Hello?" Mikey called out, poking his head round the large door of the library. His voice echoed through the huge room and he cautiously stepped inside. "Ms. Jefferys?" he jumped as the door slammed closed behind him, and he let out a shaky breath. The Library had tall, wide bookcases crammed with thick books stretching all the way from the floor to the ceiling, and they lined the walls perfectly, the only part of the faded crimson wallpaper being around the fireplace on the wall opposite Mikey. There were tables and chairs in the middle of the room, but no computers and no desk for a librarian. "Weird," Mikey muttered to himself as he wandered further into the room.

Above the fireplace, there was a portrait of a man bearing a striking resemblance to the one on the stairs, although this man seemed to be older and had a much colder gaze. "Hello?" Mikey tried again, frowning as the only response he got was his own voice.

"Hi," Mikey nearly jumped out of his skin, instead letting out a less than manly scream at the voice from behind him. He spun round to face a red haired girl with freckles, who looked to be a couple of years older than him. She was carrying three old looking books and seemed to be trying desperately to hold in her laughter at Mikey's reaction. "Sorry, didn't mean to scare you."

"No no, it's fine. You didn't scare me, I just...uh..."

The girl giggled, "So what are you doing here?" she asked, looking at him expectantly.

"I, uh, I have a detention with Ms. Jefferys."

"Oh."

"What are you doing here?" Mikey asked, realising that the girl, apart from him, was the only person in the library. Didn't she have any friends?

"Uh...research!" she said, and Mikey nodded, unconvinced.

"About what?" he asked, tipping his head to try to see the words on the cover of the book.

"Religion!" she blurted, swivelling her body to try to keep the title out of Mikey's eyesight, but he had already read the cover.

"What's the history of the school got to do with RE?" he asked.

"Oh, uh, well..."

"Michelangelo!" Mikey gasped and turned his attention to the strict woman standing by the fireplace. "You are in a detention, I do not expect you to be socialising with anyone. Have I made myself clear?"

"Y-Yes, Ms. Jefferys." stuttered Mikey.

"And Miss O'Neil. I've told you before about speaking to students when they are in a detention. Leave immediately."

April nodded and walked quickly to the door, sharing a parting look with Mikey before leaving.

"Sorry Miss, I didn't think you were here." said Mikey.

"Well I was. Now be quiet and sit in that chair until the detention is over." Mikey sighed and slumped in the chair the deputy head was pointing at, leaning on the table with his head resting on his arms.

"Hey, Donnie." said Raph, entering his younger brother's room. "Can I talk to you?"

"Sure Raph, one sec." replied Donnie. His tongue was sticking out of his mouth as he carefully used a ruler to draw a diagram, and his brown fringe was hanging in his face, but he wasn't paying it any attention, all of his focus being on the task at hand.

Raph sighed. Once his brother had started on homework, there was no stopping him. "But Donnie," he tried again. "It's really important." It had been three days since Mikey's trip to the library, and Raph was really starting to notice the weird occurrences in the mansion.

Donnie put down his pencil with a huff. "What?" he looked quizzically at his brother and Raph couldn't help but smile.

"Have you noticed that there are less and less of us in our classes?" he asked, turning serious once again.

"Yeah..." said Donnie. "So?"

"So, don't you think it's weird that they're vanishing like that, with no explanation? It's happening in all the year groups – I've asked around."

"The teacher said that they're moving schools, which is pretty believable, considering how creepy this place is."

"Yeah, but in four days I've lost seven people in my maths class alone. Don't you think that's kind of suspicious?"

"Maybe," replied Donnie, "but I don't think it's any cause for concern. I mean, what can we do about it anyway?"

"Donnie, so many students are disappearing – what if it happens to us?"

"It won't, we're not leaving this school any time soon."

"But I knew those people, and they didn't mention leaving once. They just disappeared overnight!"

"So what?" asked Donnie, getting annoyed. "Why are you making a big deal of this Raph?"

"Because I think there's more going on here than we originally thought!" Raph sighed and brushed a curly lock of brown hair from his face. "Look, separately things seem normal, but put together don't you think they're a little strange?"

"Like what?"

"The moving furniture, opening windows, closing doors, creepy teachers, the age of the school, the disappearing students, the knocking on the walls" Raph counted them off on his fingers and Donnie rolled his eyes. "Casey agrees with me."

"Who's Casey?" asked Donnie.

"Boy in my PE class. We were talking about this yesterday. He said his friend, April, was looking into the history of the school to try to get more information on what's going on."

"This is ridiculous." Donnie crossed his arms.

"I'm serious!"

"You sound like Mikey!"

"Maybe he was right!" said Raph, opening the door of their room. "About this place, I think Mikey was right. I'm going to find Casey and we're gonna find out what's going on."

"Yeah, you do that," huffed Donnie as the door to his room slammed.

"Leo?" asked Mikey. Leo had decided that he and Mikey would study together so he could help his little brother get his grades up, although Mikey wasn't exactly paying attention to his elder brother's tutoring. The computer room was empty, and even though Leo would never admit it, he felt as though someone other than Mikey was there, watching them. He looked over at the painting on the far side of the room; the only wall without a row of computers against it. It was of a young woman wearing a bonnet and a puffy white dress, although, like the other paintings, her gaze was cold and her mouth was set in a firm line, staining her otherwise beautiful features.

"Yeah Mikey?" replied Leo, smiling at his brother.

"It's Thursday today, isn't it?"

"Yeah," replied Leo.

"Well, Alyssa told me that weird stuff happens every night on Thursday."

"She did?" Leo raised an eyebrow.

"Yeah."

"What kind of stuff?"

"I dunno, she just said that I shouldn't leave my room, no matter how much I might want to."

"That's a little creepy, even for her."

"I know." said Mikey, staring at his computer screen. "So what do you think?"

"Huh?"

"About what Alyssa said. What do you think?" Mikey repeated.

"Well, you wouldn't come out of your room at night anyway Mikey. I would ignore her – she's probably just trying to scare you."

"Yeah, you're right." said Mikey, although Leo could tell he wasn't convinced.

"Hey, let's go back to your room. I think we've had enough studying for one day." Decided Leo, seeing that his little brother was clearly too worried about what Alyssa had told him to pay Leo any attention. "We'll continue this another time. If you get scared tonight just wake up Raph."

"Hey!" said Mikey as they reached the door of the computer room. "I'm not scared!"

"Clearly," Leo said with a smirk. Mikey huffed and continued out of the room, and Leo took one last look at the painting before following his younger brother out.
