Our Family Secret

Chapter 2-

It's Just Downright Rude

Every day for the last week Luna had searched the library for any mention of Drusilla. Even Hermione had lent a hand, the plight of Drusilla capturing her imagination. Still, they had found nothing, and Luna didn't hold much hope of discovering anything now, after hours and hours of searching. After all, if Hermione the super researcher couldn't find anything then it meant that there was nothing to find.

Still, the research hadn't been a waste. Luna had found out enough information on what life would've been like in Drusilla's time that she'd already finished the report. And, as a bonus, she'd discovered upon an old map plotting all the known sightings of the Crinkled Gorplump. She was going to ask her father to take them on a trip to Argentina (where most of the sightings were recorded) on the summer holidays.

With the end of the research came the realization that she would probably never find out about Drusilla. Luna couldn't deny that she was disappointed. Every night she'd sat up late imagining what could have happened to her. There was the slightly boring explanation that Drusilla was still living. It was a possibility -after all, magical folk had unusually long life spans- but 137 years was a bit too long to live, even for a witch. She liked to think that Drusilla had stumbled upon the Philosopher's Stone and had become immortal: but that was a bit farfetched as well. Her favourite explanation was that perhaps Drusilla had stumbled into an alternate dimension. She liked making up different dimensions for Drusilla to live in. There was the one made entirely out of sweets; the one inhabited by mythical creatures; and the one with no shrimp. She never liked to think that Drusilla had been sucked into a hell dimension. That would be too awful to think about. After all those hours of researching and daydreaming she felt as if she knew Drusilla. Thinking about her death or imprisonment made her as depressed as if it had been Ginny who had disappeared.

Suddenly a horrible idea came to Luna. What if she'd read the name on the family tree wrong? What if Drusilla's date of death had been there all along and she'd just missed it by accident? Quickly Luna found a spare sheet of parchment scrunched up at the bottom of her book bag and took out her wand. "Faminvenio!"

The family tree swiftly mapped itself across the piece of parchment. Spotting a date close to Drusilla's, Luna called out, "Finite Incantatem!" The map stopped growing and Luna bent forward to take a closer look. After a few minutes she found Drusilla's name and relaxed a little. No, her eyes hadn't been wrong. There was no date of death. Thank Merlin she'd been right, Luna reflected as she scanned the rest of map. She wouldn't be able to take it if she'd done all that research for nothing. It was all right for Hermione -she liked researching- but for Luna it was another matter entirely.

Drusilla had a big family, Luna thought as she traced the tree back to the subject of her research project. Lots of sisters that had-

Lots of sisters that had all died at the same time. And what a coincidence- her parents had also died that same time. Luna's heart sped up. There was something seriously wrong with that. Sure, they could of maybe died of a disease- but how likely was that?

Actually, now she was thinking of it, it was probably very likely, especially if Drusilla was muggle-born. But team that snippet of information with the fact that Drusilla had mysteriously disappeared…well, Luna knew it couldn't be a fluke.

"Hermione, look at this," Luna said to Hermione, who was studying on the other side of the table.

"Can it wait?' Hermione asked, soundly slightly annoyed. "I'm trying to work out this Arithmancy equation."

"Look at this," Luna said, ignoring her protestations and shoving the family tree under Hermione's nose.

"What's the matter with it?"

"There." Luna jabbed her finger at Drusilla's family. "Look at their death dates. Isn't that a coincidence?"

"No, not really," Hermione said calmly, "life was tough in those days."

Hermione didn't believe her, but Luna knew she was onto something. People always seemed to laugh at her special sixth sense, but she knew when things weren't right. And something about this situation was definitely wrong.

"Maybe," said Luna excitedly, an idea coming to her, "Maybe they were killed, and Drusilla escaped somehow by doing something magic. That's why her death date didn't come up on the map!" It was all making sense now! That must've been what happened. Perhaps it was some wizards against muggles and muggle-borns, or- "Oooh! Perhaps it was one of those muggle serial killers!"

"Perhaps," Hermione sounded unconvinced. "And you get serial killers in the wizarding world as well."

"But not as often," Luna told her. "Serial killers occur much more commonly in the muggle world."

Her words seemed to trigger Hermione's memory, as a frown crossed her face. "What year did they die?" She asked suddenly.

"1870."

"There's something familiar about all this," Hermione had put her Arithmancy book down. "I should know about this!"

"I don't see how," Luna answered reasonably. "And it mustn't have been particularly important if you can't remember it."

"But that's just it," Hermione said puzzled. "It was something important. Now, what subject would I've heard it in…?"

Hermione faded away and her eyes glazed over. This was Hermione's thinking expression, and Luna knew better than to interrupt her. Luna couldn't think of where Hermione might've heard about Drusilla, but Hermione was rarely wrong. That was one reason why Luna liked studying with her- the older girl was brilliant at proof reading and explanations. Ginny was pretty good at that stuff as well, but she had detention with Professor Snape at the moment. The Drusilla mystery hadn't really appealed to her anyway.

Luna leant back in her chair as she waited for Hermione to come up with the answer. Today had been an unusually good day. Her housemates had left her alone for some reason and Luna had enjoyed a strangely quiet day. Snape was still teaching History of Magic, but he had been quite civil to her after she'd answered every question on his pop quiz correctly. "Finally joined the real world, Miss Lovegood?" he'd sniped at her as he handed it back to her. Luna chose to view it as a compliment.

"I've got it!"

Luna looked up to find Hermione beaming. "Really?" She asked, smiling herself. ""So what did you get?"

Hermione's face fell a little. "Well, it wasn't really what I was expecting it to be…" Hermione said slowly. "In fact, it's probably better if you read it yourself."

"Pardon?" Luna followed Hermione as the older girl crossed to the other side of the library.

"I have to admit, I was surprised at myself that I'd forgotten," Hermione said as the stopped in front of the non-fiction section.

"What did you forget?" Luna asked, getting a little annoyed. Couldn't Hermione see that she was on tenterhooks here?

"Ah! Found it!" Hermione darted forward to the shelves and pulled out a book. As they crossed back to their desk Luna craned for a look at the title. To her disappointment, there wasn't one. "C'mon, Hermione, tell me," she cajoled.

Hermione just smiled, and Luna scowled. She hadn't figured Hermione for a sadist.

"Okay," Hermione said, as they sat back in the chairs, "This is probably going to come as a surprise to you. I certainly wasn't prepared for it myself."

"Just tell me!"

Hermione flipped through the book until she came to a section titled 'Vampires'. "I found this book while I was researching for a DADA assignment," she told Luna.

"And?"

Hermione turned a few more pages. "Look at that," she instructed Luna.

Luna bent forward for a closer look.

Famous Vampires Possibly some of the most famous and well-known vampires other than Dracula were known as the 'Scourge of Europe'. For decades they brought terror into the hearts of thousands of people all over the continent.

"Vampires?" Luna whispered, looking at Hermione. "Drusilla was killed by vampires?"

Hermione gave an impatient sigh and pointed at a section further down. "Look. It goes through all the members of the Scourge of Europe."

Luna looked down to where Hermione pointed and almost had a heart attack.

"Drusilla was a vampire?" Luna whispered, her eyes wide. Well, she certainly hadn't expected that.

Hermione nodded. "Yes. She was a seer, you know. Not a quack like Trelawney, but a real seer. The vampire Angelus heard of her and wanted to make her his childe. He killed her family and drove her crazy before he turned her."

"I'm related to a famous vampire?"

"Yes. I'm so sorry, Luna-"

"That is so cool!" Luna interrupted, a grin on her face.

Hermione looked shocked. "It-it is?"

Luna nodded. "Wow. So that's why her death date never appeared. She's not dead, she's undead."

"Er...yes." Hermione looked bewildered. "Luna, you do know that she killed thousands of people…"

Luna nodded. "Yeah. That is a bit scary. But, you know, she can't help being a vampire. Crinkled Gorplumps like to feast on human entrails but they can't do anything about it because it's in their nature."

Hermione looked slightly repulsed. "They eat entrails? And you still like them?"

"Oh yes. Crinkled Gorplumps have the ability to-"

"Anyway," Hermione interrupted, "What are you going to do now? You should probably keep it a secret. You don't want people thinking-"

"That I'm even weirder than they thought?" Luna asked with a bitter smile. "Don't worry, I won't."

"I didn't mean it like that."

"It is a point, though. Not everyone is happy to have a vampire as an ancestor."

"No, they aren't."

Luna smiled. "But I am. I've never had any one famous related to me."

"Even if they're famous for the wrong reasons?" Hermione asked, raising her eyebrow archly. "You're taking this very well. If I was related to her I would disown myself."

"That's taking it a bit far," Luna said. "But anyway, most of my questions still haven't been answered."

"What in Merlin's name do you mean?" Hermione asked, surprised. "You now know why Drusilla never had a death date, why her family all died at the same time…"

"But I still don't know why she left Hogwarts!"

"I doubt you'll ever know that," Hermione said with a grin. "What are you going to do, track her down and ask her?"

"Oh, Hermione!" Luna exclaimed. "What a brilliant idea!"

"No, no, Luna, it's not." Hermione gave a deep sigh. "She's not some mythical animal that's not real. She's flesh and blood, and if she saw you she'd probably rip your throat out."

"Lots of things you think are made-up are actually real," Luna snapped, feeling a little angry. She never laughed at what Hermione thought.

"Look, Luna, I am sorry. But I can't, in all good conscience, let you track down a psychotic killer."

"I just want to know what happened to her," Luna protested, standing up and grabbing her book bag. "Anyway, you're not my dad. You can't tell me what I can and can't do." And with that, Luna turned on her heel and stormed out of the library.

Hermione watched her go with a frown on her face. Then, with a sigh, she pulled the book towards her and began to read.

For such a brilliant day, it went downhill pretty fast. First, Luna had had the fight with Hermione. Then Filch had caught her running back to Ravenclaw Tower and had given her detention. When she finally got back to her dormitory, she found that her trunk had been rifled through, all her sweets eaten, and someone had broken her statue of a Welsh Green that always sat on her bedside table. The statue was fixed with a quick repairo, but Luna fancied the snout was still a bit crooked.

She was most upset about Hermione, though. Of all the mean things to say. To Luna, those creatures were as real as Hagrid's dog Fang. Hermione had no right to say that they weren't. And to top it all off, she called her Aunt Drusilla a psychotic killer. Luna supposed that that was true, but she never went up to Draco Malfoy and told him his father was a murdering Death Eater who ought to rot in Azkaban. For one thing, it was just downright rude.

"Luna!"

Luna turned to see Hermione racing down the stairs towards her. "Please go away, Hermione. I'm making a concerted effort not to talk to you."

"I wanted to say I'm sorry," Hermione said quickly, stopping in front of Luna. "What I said was out of line, but I was just worried about you."

"I accept your apology," Luna said, her face breaking into a smile, "and I'm sorry that I'd made up my mind that I was going to ignore you for the rest of the week."

Hermione stepped into line with Luna as they made their way to the Great Hall for breakfast.

"I've been searching for the last few days, and I've found the last known location of Drusilla." Hermione said, reaching into her pocket and pulling out a list. "Drusilla was last seen in Los Angeles, America, after her sire set her alight."

"How terrible of him!" Luna interrupted.

"Very terrible," Hermione agreed, though she sounded more as if she agreed with Angel than Luna. "Anyway, she disappeared after that and no-one's heard from her since." Hermione hesitated. "If you really want to know what happened to her, LA is probably the best place to start."

"Oh, thankyou, Hermione!" Luna said brightly, throwing her arms around the older girl. "I could never have found out all that by myself."

"I know you couldn't," Hermione answered, her voice slightly muffled by Luna's arm. "So I know I'll blame myself if something happens to you over there."

"Thankyou, thankyou," Luna said, pulling away. "I'm going to owl my dad straight away and ask if I can go to America in the next holidays. They're only four weeks away, you know." Luna clapped her hands together excitedly. Something occurred to her and her face fell. "But where am I going to stay? Daddy can't come with me- he's going to Zimbabwe for a few months. I'm supposed to be staying at my aunt's."

"I've thought of that too. I don't want my friend staying with some total stranger. Anyway, LA's a dangerous place. All those crime shows are set in LA and who knows what might happen if you're by yourself," Hermione paused for breath.

"What are crime shows?" Luna asked, curious.

Hermione sighed again. "Never mind. But my favourite uncle lives in LA. I could probably arrange for you to stay with him for a few days."

"Really?" Luna brightened. "Hermione, wow!"

"I know you won't stop looking for Drusilla, so I want to make sure you'll be as safe as possible," Hermione said worriedly. "My uncle is a muggle, though, and he has no idea magic's real. I'll need to teach you a bit about the muggle world."

"You won't need to teach me much," Luna replied. "I take muggle studies. I know all about fellytones and Davy-Dee players."

"I'll just er- test you to see what you know, then," Hermione said, struggling to hide a laugh.

"So what's you uncle's name? So I can tell my dad," Luna explained.

"Wesley Wyndham-Pryce," Hermione answered. "I haven't seen him for a few years, but I email him sometimes. He's nice, a bit geeky though. He's a complete and utter muggle- no clue about anything mystical. Oh well, I'm sure he'll say yes, and we'll see what happens then."

Luna was still beaming. "This is going to be so much fun!"
