A/N: Kay, hope you guys like it! I am in LOVE with the idea of an NCIS/Harry Potter crossover. And don't sweat it, I'm still working on Castaways!

The entire school was in a state of shock. Class as usual had lost all meaning. Professor Trelawney was so distraught that she had been holed up in Dumbledore's old office for hours being consoled by a flustered Professor McGonagall. Even Snape had seemingly lost a little of his callous touch. He couldn't be too hard on them, not after what had happened. After they had found her.

The entire Second Floor corridor had been cordoned off, the ghosts guarding it especially grim today.

At about six thirty that morning, Parvati Patil had run heartbroken from Cormac McClaggen's dormitory and to the girls' bathroom to wash her tear-stained face. That was when she had noticed that one of the cubicles was locked. Wondering who else could possibly have been up at that hour, she had decided to investigate. She knocked on the cubicle door.

"Hello…who's in there?" she called. She was greeted with silence. Parvati knocked softly again, pressing her ear to the pale green door. She could not even hear breathing. Thinking that the occupant could have somehow hurt themselves, she took a quick peek under the door. Yes, she could definitely make out a pair of legs. Panicking now, Parvati reached into the pocket of her robes and drew her wand.

"Alohomora," she whispered.

Parvati could have spent her entire life preparing herself for the sight that awaited her behind that pale green door, but it still would have had the same effect on her.

The door blasted open off its hinges and a myriad of colours hit Parvati's eyes. The first was brown, of the girl's hair.

The second was red.

The girl was on her knees, her arms slack at her sides. Her light brown curls splayed messily around her face. Her face that was currently hanging inside the toilet bowl.

It almost looked like she was just being sick. Parvati probably would have believed that, if it weren't for the silence.

And the blood.

The white porcelain seat was stained in puddles of the thick, crimson liquid. It looked like a massacre. Lighter shades of red were spattered over the walls, and a deep, clotted slit ran across the length of her pale throat. The contrasting, almost-black blood from the wound dripped slowly onto her once-white school blouse.

Parvati's throat went dry. Her knees began buckling under her as she let out a strangled scream. Her vision swam and her head spun as she collapsed to the ground, uttering one word before giving in to the blackness encroaching her.

"Lavender…"

Tony DiNozzo sat at his desk, in the process of rolling up yet another paper ball to throw at an irritated Timothy McGee. Across from them sat an exasperated Ziva David, rolling her eyes at the childish antics of the Senior Agent.

"Really, Tony. Must you always torture McGee like this?" she sighed.

"All part of the job description," smirked Tony, as he launched the freshly wadded paper ball at McGee's head. The Probationary Agent groaned at the impact. Tony raised his arms in victory until he felt a small object collide with the back of his head. He shot Ziva an accusatory glance. She held her hands up in surrender.

"Do not look at me! I did not…"

"I did," said a familiar voice.

"Boss!" squeaked Tony. "Heh, I thought you were in a meeting with the director…"

"I was," Gibbs said simply. "Gear up."

The agents began retrieving their equipment.

"Dead Marine?" asked Tony.

"No."

"Dead Naval Lieutenant?" suggested Ziva.

"Nope."

"Dead Commanding Officer?" asked a puzzled McGee, his expression matching that of the other two agents.

"Nope," said Gibbs again.

"Then what-"

"You may want to brief them first, Jethro," said Jenny from the second landing on the stairs, effectively cutting Tony off. Gibbs gave her a look, but decided against defying her. He proceeded to put his things down on the desk.

"So, no dead Marine?" clarified Ziva.

"No. Dead teenage girl."

*Phoof*

"Uh, Boss? How is that our jurisdiction?" Tony asked.

"Well if ya'd shut up for a second, I could probably explain!" said Gibbs, annoyed. Ziva snickered and Tony shot a glare at her. Jenny walked down into the bullpen.

"Perhaps it would be best if I explained, Jethro," she said, putting her hand lightly on his shoulder. Tony and Ziva exchanged looks as Gibbs handed the reins over to the director. She clicked a button and a picture of a pretty brunette girl appeared on the screen.

"Lavender Brown, discovered and identified by her friends a couple of days ago. Her throat was slit, but we won't know for sure if that was the cause of death until we get Ducky to have a look at her," Jenny explained.

"Then, what are we still doing here?" questioned McGee. Jenny sighed.

"She's at a school in England."

Everyone's mouths fell open.

"Again, how is this our jurisdiction?" exclaimed Tony. Jenny ignored this and continued.

"Her father is U.S Lieutenant Kevin Brown, part of top secret government operation 'Black Storm.' Moved from Britain when his daughter started school," she said.

"Black Storm?" asked Ziva.

"We can't go into details on that," said Jenny, "but basically he saw something he shouldn't have. He's been receiving threatening emails from an untraceable account somewhere abroad, promising death and suffering. We believe that this may have been the writer following through on the 'suffering' part. Making it," she paused, her eyes resting on Tony, "our jurisdiction," she finished, walking away. There was silence for a few moments.

"Ya waitin' for an invitation? Get goin'! We've got a plane to catch," said Gibbs.

"…an-and then, I found her," sobbed Parvati, "and blood, there was so…so much blood," she wailed. Professor McGonagall nodded her head grimly. Snape stood in the corner of the office, as surly as usual. Light sniffles came from the other corner where Professor Trelawney rocked backwards and forwards, curled in a ball, hiccupping every now and then.

"Thank you, dear. You may go back to bed now, Miss Patil," ushered Professor McGonagall, helping the distraught girl out the door. She sighed.

"Severus, what is happening? Such a brutal…muggle way of killing! Whoever did this intentionally wanted to cause pain!" she exclaimed, horrified.

"Some people…enjoy it," said Snape. McGonagall's expression was one of sheer terror.

"Severus…we have had no break-ins for years. Do you realize what this means?" she cried. Snape gave a curt nod.

"We have a psychotic killer…inside our school!"

"That stupid plane couldn't have bumped us up to first class?" Tony complained as he rubbed his neck. Ziva rolled her eyes.

"Get over it, DiNozzo," said Gibbs. The team sat on the empty Hogwarts Express after an exceedingly weird explanation from Director Shepard that magic was, in fact, real. They still had a hard time believing it, except for McGee, who seemed extremely interested.

"Hogwarts School of Witchcraft and Wizardry…" he mused aloud. "Says here they're the top sorcery school in the world, impeccable education record…" he said as he flipped the page of his pamphlet.

"Hmph, seems like you've finally found your kin, elf-lord," sneered Tony. Abby punched him in the arm, hard. He winced. "Point taken," he hissed through his teeth in pain.

"Well I for one am excited! I knew magic was real!" Abby said excitedly. "Although I'm gonna have to find a British supplier of Caf-Pow…" she continued, slightly put out. "I can't believe they actually pulled in a muggle lab for me!" she squealed. The others gave her blank looks.

"A what lab?" asked a puzzled Tony. Abby sighed.

"Muggle! You know, non-magical people? Like us!" she explained. The team didn't even bother to ask how she knew this.

"It sounds like a dirty word," said McGee. The others shrugged.

The steam train wound its way around the mountain like a brilliant red snake, exposing the lush green valleys below. Ziva sighed.

"It is beautiful," she said, wistfully. An unexpected thought occurred to Tony at that particular moment, but one he would never say out loud. His hand spasmed slightly as it sat next to Ziva's, and he instead settled for a simple "It is." Ziva saw the twitch and her intuition told her that there was more on his mind. She turned and gave him a small smile. They locked eyes for a fraction of a second before looking away and discarding the entire thing. Gibbs sighed as he watched. This was going to be a long trip.

Professor McGonagall and newly appointed deputy Headmaster Professor Snape stood at the tall iron gates of Hogwarts in anticipation of the Muggle investigators arriving at their school. This crime was committed like a muggle, she had decided, so it should be solved like one. She had called the police, but they had referred her to a national organization, saying that this was "much bigger than they thought" who in turn had called up U.S.A authorities and had decided that this was best solved by a unit called NCIS, who solved mysteries in relation to their Navy. She did not understand why, but was read into it, discovering that Lavender's gruesome murder may have been a hit on her father.

This had made Minerva's blood boil, torturing and murdering an innocent young girl to punish her father. It was sickening. Now Lavender would never grow up, have children, fall in love…although it may have been a while before that last one happened after her latest heartbreak involving a certain Weasley child…

So Professor McGonagall had expected at least something like the investigators she had seen on television, that muggle contraption. Tall, heavy-set, surly fellows, with bristled moustaches and gruff voices. Nothing like what had come out of that black car.

The car drove madly around the corner, swerving to avoid a herd of Thestrals. She wondered for a moment why they could see them, but then remembered that being police—they would have seen a lot of death. Maybe even caused it. Drifting in a circle after heading in the wrong direction, the car screeched to a stop in front of the two shocked educators, the doors opening.

And what she had been expecting, had been entirely wrong.

The first man that stepped out was young (for her) and very good looking, with a charming smile that only seemed to be on display because he had escaped the dangerous vehicle. The smile vanished as his head swam.

"I swear Ziva, if I'm ever in a car with you driving again, just shoot me before you go. It would be a much less painful death," he groaned. The next person that stepped out of the car was a woman, exceedingly beautiful with long dark curls, and very exotic looking. This must be 'Ziva.' She grinned mischievously as the next passenger stumbled his way out of the vehicle. He was cute, a little chubby, and looked like he had a good head on his shoulders. The next thing that the teachers saw emerge from the doorway was a ten inch high, shiny, spiked black boot. They gulped as the boot was followed by a pair of black lace stockings, a red, chained tartan skirt, a white skull top and a pair of jet black ponytails. But all of their anxiety melted when they saw the huge, excited, bubbly grin on the girl's face, and the way she was jumping up and down. After that, the next person that came out was…in fact not a person at all. The tiny yellow lab waggled its entire body as it bounded around the Goth girl's boots with ecstatic energy.

And the last figure that materialized in front of them near made Minerva's heart stop.

You could tell he was the boss; authority oozed from his pores and he carried himself with pride. His silvery-grey hair swept over his head lightly, and his eyes sparkled sky blue.

He was probably the most handsome man that she had seen in her entire life.

And that was a long time, she thought as she sighed in awe.

A/N: LOL McGonagall likes Gibbs! Hahaha! Please, please, pretty please review! Thank you! OH by the way, as you could probably tell, in my world, Jenny is still alive, Abby still has Mortimer and…basically anything that may seem like it doesn't make sense actually does! REVIEW! :D
