It had been two weeks since Cammie and Zach had been spotted in Australia. Nothing since. Not even Tina had heard anything and that was worrying. It had been almost three months and she hadn't heard anything.

It was lunch and the whole of my year were outside enjoying the September sun. My roommates and I were listening to Lauren telling us about the latest fashion in England. Well, I sort of spaced out. As much as I love fashion, I was writing an Ancient Languages essay, eating a marmite sandwich and worrying about Cammie.

"Hey, Bex? You okay?" Lauren scooted over to me. She was actually a nice person when you got used to her ridiculously short skirts and her blunt way of saying things. "Yeah. I'm fine." I said lamely, not bothering to put on a fake, cheery voice. My English friend just raised a perfectly shaped eyebrow. "Come on, Bex. What's wrong, seriously?" I sighed and pulled at the grass. "It's Cammie. These stupid twats are after her and no one knows why." I blinked back the tears. I wasn't usually one to cry but my best friend could be in trouble right at that very second and I was lying on the grass doing homework. "Someone knows." Lauren whispered. Whoa, déjà vu, I thought.

"Hey, guys! Mr Solomon is headed towards us!" Liz stage whispered and hastily straightened her skirt. I finished off a Latin sentence in my Ancient Languages essay and gathered up my pens (which could also stun someone if you pressed the nib). "Change into normal clothes and meet me by the foyer in ten minutes." Mr Solomon said, "Even you Liz. Tell the rest of your CoveOps classmates as well." And with that, he left. Liz looked very confused.

Macy was on the verge of yelling at Liz because she refused to wear eyeliner and I was deciding which handbag I was going to bring. "I think the black one." Lauren appeared at my side in the mirror, "It's the most practical." I gaped at her in disbelief. The girl was wearing six inch heels, for God's sake! I was starting to think that she didn't own a pair of flat shoes. "Plus, black goes with everything." She stated, seeing my jaw drop.

"For God's sake Liz! Wear the damn eyeliner!" Macy screeched.

"No! I'm not going to be chatting up boys! I don't even know why I'm going." Liz made an excellent point and Macy growled in frustration. Why was Liz going? It was a CoveOps practical and Liz wasn't taking CoveOps anymore.

"Maybe Mr Solomon needs help with electrical equipment?" Lauren guessed while touching up her red lipstick.

"Okay girls," Mr Solomon clapped his hands and looked round at the girls waiting in the foyer, "Your mission is to find a disc. The disc has a password so you have to find the password too." He spun on his heels and led us to a van.

Once crammed into the van, we were handed comms units. "Miss McHenry, was the driver of the car that just passed a man or a woman?"

"Trick question, it was a truck and it was a man around his late fifties."

"Very good Macy." Mr Solomon nearly smiled. Nearly.

"Sir, why am I here?" Liz asked after fifteen minutes of silence.

"Well, Liz, you know the most about computers."

We clambered out the back of the van when we got to a very busy mall. "You have until five to retrieve the disc and get the password, ladies." We split up in groups; me, Lauren, Macy and Liz together and Anna, Tina and Mick together.

"What about the guy in the trench coat? It's far too hot for a coat!" Liz said quietly as we went down the escalator. "No. He's alone and if he had the disc he would have backup." Lauren replied. We passed the other group and Anna shook her head and carried on walking, it was such a small gesture that no one would've noticed, except for us of course.

An hour later we were no closer to getting the disc. "Hey, didn't we see those boys come in here just a minute ago?" Macy elbowed Lauren as three (really fit) boys left the cafe we just entered. "Yes." And so the following began. We kept our distance but had them in sight until they went in the men's loo. "I guess we wait until they come out now." Liz said sitting down on a bench.

"No. We follow them." I told my brainy friend.

"What?" She squeaked loudly and the group of old ladies behind us stared. "They're in the men's bathroom! We can't just waltz into the men's toilet! In case you haven't noticed, none of us are men." She lowered her voice.

"They could climb out the window and then we'd lose their trail." Lauren said, "I have an idea. Follow my lead." She grabbed Liz's hand to prevent her from backing out and marched in the men's toilet. "Oops! Wrong loo!" She said very loudly and then walked out again. "What was the point in that!" Macy exclaimed. Liz had turned a startling shade of plum. "Well, all the stall doors were open, the boys weren't in there and the window was open."

The four of us pushed our way through the crowded shopping centre which had filled up considerably because of all the teenagers who had just been let out of school. Finally, we got to the car park. The boys were nowhere to be seen. "Great, we've lost them!" I threw my hands in the air in frustration. It was quarter to four. Time was running out. "There they are." Macy nodded towards the traffic lights.
