~*Amelia's POV*~

The hall was finally up to standards for a Trinians party and the bar was set and ready to supply drinks. Kelly had put me in charge of overseeing the first years who were transporting the drink from one of the basements, where it was kept.

I walked back up to the dorms with everyone to get changed, no doubt. When we got there all the girls went to their respected area and I went to my small space next to Annabelle. I had noticed that Annabelle fitted in perfectly but she had her own space, she didn't look like she fitted in with any of the cliques either. It made sense that she had her own space I guess. I noticed she would spend most of her time with Kelly, who being head girl probably couldn't be in a clique.

"Are you alright?" Annabelle's concerned voice reached my ears and pulled me out of my thoughts.

"I'm fine, why?" I assured.

"It's just you were staring at me." She said flatly.

"Sorry, I didn't mean to." I apologised, embarrassed I had spaced out staring at her.

She seemed to lighten up after I apologised, like she had suspected me to be staring at her because I was judging. She went back to getting ready then I noticed that the girls weren't changing. They were only toughing up make-up and altering their uniform slightly where it had been changed during activities of the day.

"Umm...Annabelle?" I called her quietly.

"Yeah?" She said

"Why is everyone staying in their uniform?"

"Oh, it's because another school is attending and something else to do with pride for our school probably." She explained.

After that I decided to do the same, not that there was much for me to do. My black skinny jeans hadn't changed during the day and my shirt was just as plain as ever. The way I wore my uniform didn't look anything like St Trinians, I had never had the opportunity to alter or change the way a school uniform looked. I was stumped by this and had no idea how I would change it anyway.

The party had started and it was a riot, just like Annabelle and Andrea had warned. Lots of people were on the dance floor, some were stupid dancing others were better and were showing off. Girls were sat around the circular tables that had been put up and were talking with friends, others were off in corners snogging some of the boys from the other attending school, which of course was an all-boys school. Some were sat at the bar chatting and drinking, even the first years were purchasing alcohol that they otherwise wouldn't be allowed to drink. The band of St Trinians was on the stage playing the music that people were dancing to.

I was currently watching Kelly and Annabelle who were dancing. Kelly was making a joke of grinding against Annabelle, who was laughing and blushing at her best friends actions. Chelsea who was nearby was laughing along with Kelly at Annabelle, whilst she danced with some of the boys from the other school.

I was watching and observing people from a seat in the corner of the room with a glass of whiskey and my own company. A few people had approached me, like Andrea, who had come and talked to me for a bit before she saw a guy on the dance floor who sparked her interest. I was waiting for the moment when most people would be to drunk or involved in the dancing to notice someone leaving the party.

An hour maybe two went by and it was coming up close to midnight, the party had started at four when everyone was in the hall. The room all of sudden went quiet and I thought the band had given up playing. That was when I noticed they had started a new song but it was quieter than the others. Practically all of the girls made their way onto the dance floor, leaving a very small proportion of the student body around the outside, not dancing. It was only once the song got going did I hear the lyrics.

"We are the best, so screw the rest!

We do as we damn well please!

Until the end, St Trinians!"

It was their school song, which I probably should have guessed they had, and it was being led by Kelly. Kelly was walking through the crowd of students with a bottle of bear held above her head. She had a look of extreme pride about her and all of the other girls looked the same, even the ones not dancing.

I made to exit the room, this would be the perfect opportunity to get out. Before I left I gave the room a last quick sweep to see if anyone was watching, there wasn't thankfully. So I slipped out the double doors quietly and unnoticed, but not before I caught the look Annabelle was giving Kelly. The look was one of pride, defiantly but there was something else there as well. She had been looking at Kelly, which figures. Every time Kelly turned her back Annabelle always managed to give away just a bit of an emotion, love? I couldn't be sure whether it was but I had caught Kelly once giving Annabelle's retreating back the same look.

Pushing the thought of Kelly and Annabelle aside I opened the door to the dorm and entered. It was, as I predicted, completely empty. Someone had left the lights on as well, which made it easier to see and meant I didn't have to stumble across the whole dorm to the light switch. I walked briskly over to the geeks section and started looking for Polly's laptop. I found it on top of her bedside table with its lid left open. I sat down on the bed where Polly had been sitting when everyone was getting ready.

Of course Polly put the lock screen up to stop people getting onto it. Earlier during the week, when I was planning against them, I knew that this was what I wanted to do to get back at Polly. So while she was off doing a perimeter check, I installed a camera above where she usually sits. It was a spare on from the ICT class, so it wouldn't be missed when the geeks came to check the security cameras. From the recording of Polly logging onto her laptop I managed to figure out her password.

I wasn't the biggest wiz with computers and technology but I knew more than most people did. Well I knew enough to be able to hack Polly's computer so that every time she logged on before her desktop came up she would receive a message that would be reading:

"WARNING: Some of the cookies from the website /gayporn have been permanently saved to the zip folder; 'St Trinians Pictures'."

I did this by changing the programing for the start-up of the laptop ever so slightly and leaving my own message behind. The next step would be to add some photos to the zip file that was on here. I knew the zip file was there because Polly had shown me some pictures from the start of the year. When she had I noticed the folder was a zip folder, this meant that anything in the folder couldn't be taken out but it could be added.

I searched the internet for inappropriate pictures and found quite a few that would be good enough. I saved them all to the zip folder and then cleared the parts of the internet history that showed me searching the images. I then went and checked the folder for the images I had saved. As expected they were all there.

Two out of three pranks complete, one more to go.

I placed Polly's laptop back where it belonged and went to find what I would need for the next prank. I went back to my draw under the bed, this time pulling out a packet of party poppers and a siren. The siren was a pranking siren and could be used to record a simple warning message then a siren would go off. This would repeat until it is stopped by someone. The siren is easily trigger, like a gun when you want to fire it. The siren is in the shape of a megaphone and was the gift that Aunty gave me. As for the party poppers I would be attaching them to the bathroom door.

Before I could begin to put the prank up and together I needed to get into the head girls room. I sat on my bed for a moment facing the door opposite it. I knew that Kelly locked it with a key that she kept with her. However I also knew that Annabelle had a spare. I just need to think where Annabelle would have put it.

Then it hit me, Annabelle has a box underneath her bed that she puts things she treasures in. The lock on that would be easy enough to pick. I grabbed to hair clips off the side of her bed side closet and pulled out the box from the side. I used the hair pins to unlock it, the lock was surprisingly better than I thought so it took me an extra minute than I wanted to get in.

Once in I tried not to look at most of the stuff in there, I mean it is her privet stuff. I found the key without having to move to many things aside. I picked it up and left the box open on the floor half hidden under her bed and walked over to the head girl's door.

Here goes nothing, I thought.

The door opened with a satisfying click and I entered triumphantly. Not really wanting to spend too much time doing this, conscious that someone might notice my absence at the party. I rushed back out to collect the party poppers and the siren. I used a stall and attached the siren to the ceiling above the door, I did this on the inside of the room so that no one would notice it until it was set off. I then attached a piece of string, that I had stolen, to the trigger and then to the door itself. The string was loose so that it would be pulled tight when the door was fully open, which would set of the siren by pulling the trigger.

With that set I looked around her room, it was of a good size with a double bed placed in the centre of the wall on the left side. The bed had space either side that was occupied by two small bedside closets like the ones that we all had in the dorm. There was a window at the other end of the room, it had a window seat with cushions and a book was left upside down marking a page. There was a desk against the right wall that had a laptop on and other books and bits of paper and a stationery pot. Next to the desk was a door, presumably her personal bathroom.

I opened the door and sure enough it lead to a slightly messy bathroom. Mostly different bottles of stuff lay around, things that I had never heard of. Mostly it was the brands on the bottle that I hadn't heard of, other times it was what was in the bottles.

Ignoring the bottles and slight mess, I grabbed the chair that I had also used to put the siren up and pulled it over to the bathroom. I stepped onto the chair and used the same cello tape to attach the poppers to the door frame. I then attached the strings from them to the door on the outside of the door, thankfully the strings on them reached.

I then grabbed the chairs and the equipment I had used and exited her room, I used the key to lock the door and then placed that back in the box. I made the box look as identical as I had found it and placed that back where Annabelle had placed it. I stood up and looked around the dorm everything was as it should look, nothing stood out or looked suspicious. I had removed the camera from above Polly's station earlier when I left her the message.

I made my way back down to the party making a pit stop at the ICT rooms to drop off the camera. When I re-entered the party everything was as it pretty much had been an hour and a half ago. Obviously the people had moved about got drinks and stopped and started dancing, but it didn't look as though they suspected me missing. I sat at one of the stools by the bar and ordered another whiskey, I just couldn't keep away from it.

After about another hour or so the party had died down and Miss Fritton had come in to close it to an end. The girls who had fallen asleep at their seats in the room or on the floor were left there. The rest made their way to the dorm slowly. Some girls were using their friends for support, too drunk to walk themselves. Somehow Kelly, Annabelle and Taylor found me in the mass of people walking up the stairs.

"Ya know, you is a proper party pooper ain't ya?" Taylor said whilst walking slightly wonkily up the stairs beside me.

"Am I?" I replied

"Yeah, I didn't see you on the dance floor once tonight." Annabelle said, there was a look in her and Kelly's eyes, which said that they knew I had left.

I shrugged and said, "I don't like parties." which is true, I hated them in fact.
