"When you have eliminated the impossible, whatever remains, however improbable, must be the truth."

Sir Arthur Conan Doyle

Abby shot up from her coffin a scream escaping from her mouth. She fumbled for the light as she grabbed her silver locket and grasped it tight in her hand. She breathed deeply trying to calm herself down, after all it was only a nightmare. Except to Abby it was more than that, it was a memory.

The clock on her bedside table read 5:20, no point trying to get back to sleep now. She sighed, removing her covers. After getting both feet on the ground she stood up, resting a hand on the table to support herself. With the locket still clenched in the other hand, she made her way towards the fridge. After removing a caff-pow and taking a gulp, she fumbled wearily over to the sofa. Ever since that fateful night, Abby had struggled to sleep. Well, more refused than struggled. Every time she closed her eyes the same pair of amber ones would stare back at her. During college she'd come across the glorious invention of caff-pows and never looked back. Not only did the caffeine keep her up, it held the memories at bay.

She opened her cell phone and stared at the display. She pondered over whether to call Gibbs or not but as usual she came to the same conclusion, no. She couldn't tell him what really happened, he wouldn't believe her. To be fair, Abby struggled to come to terms at the beginning too. After the hunter, John, had rescued her, he tried to explain everything. All about how the myths and stories are true, about demons and werewolves but, being partly still in shock, it didn't sink in for a few hours and by that time he was long gone. After dropping her off to the hospital, John had given her his number, for if anything popped up again, and the 'don't tell the hospital what really happened' speech before driving off into the distance in a classic old Impala. She'd never called him though, he didn't seem like the person who would give you a shoulder to cry on. Although she didn't want to believe anything that happened those three days, science couldn't explain the events, it must have really been the truth.

Armed with her new best friend, caff-pow, Abby had spent the next two weeks researching everything she could find about werewolves. The coffin wasnt due to being a twilight fan but instead due to vampires being werewolves worst enemies. She came up with the idea that if she looked and acted like their mortal enemy, they would leave her alone. To be honest, it had worked well so far.

Every myth portrayed them in a different way. Some said silver would hurt them, others said normal weapons, so Abby had done the only thing that seemed sensible at the time. She joined a church. It gave her confidence that there was someone else out there supporting her every day and a figure to combat all evil. It was also part of the reason she started at NCIS. Afterall, werewolves are partly human so, sometimes evil is human too.

When the clock turned 6:30 Abby decided it was late enough for her to turn up to work without alerting to the point that she couldn't sleep again. Although he never pried for answers, Gibbs gave her a knowing look as he delivered his first caff-pow of the morning to her.

"You alright Abs?" he asked as he walked through the door of her lab. She nodded, taking the caffeinated beverage and its safety into her hands. "We've got a case up in Baltimore, they found the body of a Navy Seal. By the sounds of things there's going be a lot of blood analysis for you. I'm going to head over as soon as the rest of the team gets in."

She took a sip, caffeine adrenaline shooting through her. "Yeah, no problem Gibbs. Lets catch a bad guy!" she replied embracing the old agent in a hug. After taking in the scent of woodwork and bourbon she trotted back to her computer as Gibbs walked towards the elevator. Secrets were hard to keep and it took all her strength not to call after Gibbs and embrace him again. Taking another sip, Abby pulled over her chair and sat down at her desk. Pushing the memories to the back of the mind she started up her computer and reached for the locket that always hung around her neck. She gripped it tight.

Two hours later when the crime scene was fully investigated and all evidence bagged and tagged, Gibbs and the rest of the team returned back to HQ. When Gibbs had said they had a body he was slightly off. It was more like multiple body parts that would make up a Navy Seal had he not been ripped to shreds. It was a spineless attack which bared resemblance to a wild animal attack. Teeth and claw marks were all over the torso which had been ripped open by the attacker.

Bishop had collected a hair from the gaping wound where the organs would normally be contained and it was down to Abby to analyse it to confirm the species of animal so they could alert metro to be on look out for any wild animals in the DC and Baltimore area.

A bleep sounded from Abby's computer, Ducky the coroner, was requesting a video conference. "What's up Duc?" asked Abby, peering at the small screen which now housed Doctor Mallards face.

"My dear Abigail, I would focus your work around the torso area. Although the victim sustained multiple injuries and dismemberment it was all post-mortem."

"So what killed him then?"

"His heart was ripped straight from his chest. This obviously caused multiple problems for the dearly departed so his death was fairly quick and painless. In fact, it's the only part of him we don't have accounted for. It is said however that the heart is one of the most vitamin rich organ in the human body so I can understand why the animal took more of a liking to it than..."

Abby didn't move. She closed the video conference without a goodbye and reached into her back pocket retrieving a cell phone. She flipped open her phone entering Johns number into the display. After a glance up to check her lab she pressed call. The phone beeped in her shaky hands as she lifted it up to her ear. "Hello?" answered a rough male voice from the other end of the line.

"Is this John Winchester?" Abby enquired.

"I'm sorry, he's not available at the moment." the man replied.

"Well... Um... Sorry... Just tell him Abigail Sciuto called and... Get him to call me back."

"He can't."

She paused thinking everything through. "Um... Okay never mind then. It's just something popped up and well..."

"He's dead."

"Oh. Look I'm really sorry for your loss and just forget it okay. Never mind, I just thought I had a case and..."

"What sorta case."

"Well I'm a forensic scientist for NCIS. We're kinda like the FBI except not. We only deal with Navy deaths and stuff like that but they don't and plus the FBI are also meaner. And well, the team just found a body of a Seal by the name of Thomas Jones. All evidence points to an animal attack, ripped clothes and paw marks and all but the thing is he was found in a suburban area, witnesses saw a man entering the alley beforehand and its around the full moon."

"That doesn't necessarily make it a werewolf attack." grunted the man on the other end.

"His heart was missing. Not just missing more like ripped from his chest missing."

"Hmm." he pondered, another male voice could be heard faint in the background. "Okay, fine. Well it does sound like a case, me and my brother will come check it out. Where abouts are you?"

"Washington DC." The elevator pinged as the door opened. She heard Tony arguing with McGee about how the the murderer was a character from the movie 'The Wolf Man'. "Look I can't talk now. There's a diner on 53rd that does decent hamburgers, I will meet you there. Call me when you arrive in DC." She hung up the phone in a rush before she could hear the reply. Turning right as Tony entered her lab, Abby placed her phone in her back pocket before walking over to her computer and pulling up the hair sample on the screen.

"Look Tony, just because a witness saw a guy enter the alley just before Ducky's estimated time of death it does not mean a modern version of Larry Talbot killed the guy." started McGee. "Abby will have analysed the hair Bishop found on what was left on the body. It will come out as dog or fox or some animal and that will be that."

"A very hungry, angry animal McHopeful."

"Sorry McGee. Its human. No DNA on it to trace by but there's no doubt that it came from a man."

"There we have it Tim, the Wolf Man strikes again."
