Disclaimer: You know I don't own Harry Potter. I wish I did, but I don't.

"Can you believe that Teddy and Aunt Luna are here?" Lily Luna knew she sounded overly excited, but at that moment she didn't care. It was only Scorpius she was talking to, after all, and he had grown used to her occasional moments of hyperactivity. "I wish you were taking Care of Magical Creatures. Aunt Luna's awesome."

"I gathered that," said Scorpius dryly as they slowly walked around the lake, just talking. Rose had gone off to study- typical- and so they were alone. The students had already been back at Hogwarts a week, but somehow it felt longer, probably due to the amount of homework both the fourth- and sixth-years were already receiving. "Anyway, I don't have time. My schedule's already insane enough as it is."

Lily started to open her mouth to reply, but a first-year Ravenclaw cut her off. The first-year was clutching her side as if she had just run a long distance. "Rose…" She panted. "Wants…you…to…meet…her…in…the…library."

"All right then," Scorpius said. "Come on. Let's go, before Rose comes after us herself."

"She probably just wants to make us start on homework," Lily grumbled. Rose was the brains of the trio. Without her, the others wouldn't get half of their work done, it seemed at times when she went over their essays and corrected them. The only thing they had over her was practical things- both Lily and Scorpius were geniuses at figuring out how to actually perform spells, something Rose needed extra work with.

The pair headed to the library, attracting a stare from James, Lily's older brother, as they walked by. "Hey. Malfoy, where are you and my sister going?"

"To the library," Scorpius replied. "Put your wand away, Potter. There's nothing to be concerned about." Lily shared a look with him. James had been horrified that his little sister had gotten into Slytherin, and rather quickly as well, with barely twenty seconds spent under the Sorting Hat. He had been even more horrified when she became best friends with Scorpius Malfoy, and spent most of his time harassing them. He was in seventh year now, to Lily's happiness- one more year, and he would be gone.

"If I catch you doing anything-"

"Nothing to be afraid of," Lily said easily. "Rose called us by first-year. She's meeting us." The three were infamous for using younger students to communicate with one another. Most of the younger students were happy to oblige, being slightly afraid of what would happen if they didn't. "See you, James."

"See you around, Lils." He didn't even acknowledge Scorpius, which, after all these years, was no longer a surprise. At least he didn't hex the other boy when his back was turned, which was an improvement from earlier years, when both James and Scorpius had been in detention constantly for dueling in the corridors.

Rose was waiting for them in one of the back tables of the library, a couple of books spread out in front of her. She had obviously been doing her homework while she waited, although, of course, rarely a time came when she wasn't doing her homework. Or, (even worse in Lily's opinion) reading for fun. She looked up as they approached, and cleared her things to the side. "You'll never believe what I found out."

"What?" Both Lily and Scorpius leaned forward excitedly. Usually it was one of them who found out a big secret or little-known fact, due to their penchant for eavesdropping and mischief in general. Rose, on the other hand, was usually on the receiving end of interesting or important news.

"There was a girl who almost died today. The whole thing was horrible, you two," she added sternly, "so stop acting like this is big gossip."

"Well, it kind of is," Lily said. "Horrific gossip, yes, but gossip nonetheless. Now, tell us the details."

Rose muttered something that sounded suspiciously like 'Bloody Slytherin,' before continuing. "Anyway, you two know Sara Creevey? The Hufflepuff Chaser?" They nodded. Sara Creevey was a third-year who had joined the team the previous year, and to everyone's surprise was quite good considering her age. "Her broom had a curse on it, designed to throw its rider off. She fell, and would have died if it weren't for Madam Pomfrey. She was almost twenty feet in the air…good thing she wasn't higher. She had the sense to try to land when she noticed her broom was acting weird."

"A Hufflepuff with sense?" Scorpius dramatically fell off his chair. "I never thought I'd see that!" He got up, brushing his shirt off, and sat back down.

"Shut up." Lily smacked his arm. "Al's a Hufflepuff."

"And, he has no sense," Scorpius added, looking smug. "Did you, or did you not, tell me that your brother Al accidentally wandered into the Forbidden Forest? Accidentally? How the hell do you accidentally wander into a giant forest? It's pretty hard to miss!"

"Fine, so maybe Al has no sense, but-"

Rose sighed. "You two are completely missing the point here. Sara's broom was cursed. She's had it since the beginning of last year and it's been fine. That's not right."

"Probably just someone who doesn't like her." Scorpius shrugged. "Everyone's got enemies, right?"

"That's an incredibly advanced curse. I looked it up, and it's way past N.E.W.T. level. Not even all adults can do this. It certainly wouldn't be some student who doesn't like her."

"So you're saying a teacher did this?" Lily wrinkled her forehead. "That doesn't even make sense. Killing a student…wouldn't the death of a student cause Hogwarts to close?"

"Not necessarily. Probably, but not necessarily. And it's rather odd, isn't it, how this happened?"

"Huh?"

Rose sighed again. "The Hufflepuff Quidditch team and the Ravenclaw Quidditch team were having a small practice game on the pitch. Dozens of people were there. Wouldn't it be more sensible, if someone was going to murder someone else, to do it when nobody else was around?"

"Definitely." Scorpius nodded his assent. "Is she going to be alright, anyway? Sara Creevey?"

"Supposedly, although she's not going to be able to attend class for at least a week or two. She's hurt pretty badly- internal injuries and stuff that takes more than Skele-Gro to heal." All three shuddered, having heard horror stories about the taste of that stuff. "I'm going to pop in to see her at some point. I want to know more about this, because it certainly wasn't an accident. Professor Goldstein ascertained that much."

"So you're going to try and figure out who did this?" Lily looked skeptical. "Isn't that a bit dangerous? Trying to find a killer, or wannabe killer, anyway?"

Rose rolled her eyes. "Have you not heard the things our parents did while in school? I'm pretty sure this person, whoever he or she is, is not as dangerous as Voldemort. Besides, there's three of us, and we have a talent for eavesdropping and finding out things that we're not supposed to know."

"No," Scorpius corrected. "Lily and I have the talent for mischief. You're the bookish one. You need our talent if you want to accomplish anything. Lily's got the Marauder's Map, since she stole it from James in second year-"

"First year," Lily interrupted, "And I got the Invisibility Cloak, too, from my dad's office, right before I left for school. You need those things to sneak around."

"Fine," Rose admitted. "I need the pair of you and your tendency to break every single rule, find out everyone's dirty secret, and sneak into places that students are most certainly not allowed to sneak into. Will you help me? Pretty please?"

"Fine," Lily and Scorpius said together. Firmly, they all shook hands.

"We got ourselves a mystery," Rose said.

A/N Please review, it would make me a happy writer.
