"I have two cases that'll keep you entertained. I have a vampire at a medieval fair and a killer carnival" Lestrade explained, holding the relevant file up as he spoke. Eve and Sophia grinned and snatched the first file.

"We'll take the medieval fair, you two have fun at the carnival" Sophia said as the pair ran for the elevator. The three men watched them vanish behind the silver doors.

"Should I be worried?" Lestrade questioned, looking to Sherlock and John.

"Greg, I think you should be very worried" John answered, Sherlock nodding his agreement as he looked through the second file.

"Soph, do we really have to wear these?" Eve complained, holding up a green dress and black cloak.

"The dresses and cloaks, yes, this is a costume fair. As for that particular dress, no. The TARDIS blue one over there is yours, the green one is mine" Sophia answered, pointing to the dress hanging on the back of the door.

"Okay, a little better. What's our plan then?" Eve asked as she examined her dress.

"You're the decoy; you'll distract him, and then make him leave. Then he'll go after me, I'll act like the damsel in distress as he reveals himself, then we kill him together" Sophia summarised quickly. Eve nodded and went to grab her gun, she had a feeling she would need it.

Timeskip

"Soph, he knows I'm a hunter, he's being careful" Eve told her friend, watching the vampire in question scan the marketplace.

"I'll be fine, I'll get him to follow me and show himself. He's hungry by the look of it so it shouldn't be hard" Sophia replied, "But I'll wait a bit, let the place quiet down. Are you going to take to the roof to follow?"

Eve nodded and pulled the hood of her cloak up, then disappeared down the closest alley and found her way to the roof. Sophia watched her vanish before she crossed the marketplace, deliberately walking into the vampire.

"Oh, sorry about that" Sophia muttered. She looked casually over to Eve as she walked away, heading down the path into the park, knowing full well that the vampire was following her.

It wasn't until she got into the woodland area of the park that he made himself known though.

"Are you sure you want to be out here alone?" Sophia turned at the question.

"I'll be alright as long as you don't try to scare me to death again" she snapped in reply, surprised when the vampire chuckled.

"It wasn't my intention, I only wished to see if the young lady was alright" he answered smoothly and Sophia played along.

"All these costumes and the decorations keep making me lose my way, I used to come to the event as a little girl, but everything has changed in recent years"

"There have been quite a few changes recently that would make anyone confused, would you perhaps like me to guide you around"

"...Can I trust you not to be some creepy serial killer?"

"If I can trust the same of you"

And so, Sophia let the vampire take her arm and lead her away from the crowds. She was aware of Eve following further into the forest, able to hear her flatmate's disguised heartbeat due to practice. Spells were wonderful things to learn, allowing Eve to follow Sophia and the vampire unnoticed until they came to one of the smaller buildings at the edge of the fair.

"Thank you so much for guiding me back, I just hope I can find my friend again in all this chaos." Sophia addressed her vampire 'guide'.

"I'll wait with you until then, I wouldn't be much of a gentleman if I didn't."

"Are you sure? Don't you have a date for the event? I've seen you talking to quite a few of the women around here."

"They all seem to run away from me at the end of the day. Is it awful of me to hope that you won't be doing the same?"

"Why would I run from such a gentleman? Unless I was right and you are just a creepy serial killer with a gentleman act?" Sophia suggested. The vampire laughed a stereotypical villain laugh and slowly guided Sophia away from the fair again. Into one of the back buildings. The building there had been crime scene tape around earlier that morning.

The crime scene team had worked fast, at Sophia and Eve's request, to gather what they needed and clear it. They had been told there would be another crime scene by the evening, the vampire doing the killing (because they knew something supernatural was behind it) hopefully and had done as the girls had asked.

"Perhaps I am, perhaps I'm not. Why do you seem so interested in that possibility?"

"Because three girls have gone missing from the fair in as many days. Something has to be up."

"And there's no investigation going on?"

"They're in amongst the fair now, they're giving everyone warnings about walking off with strangers alone and all that sort of thing."

"Yet you chose to ignore that advice?"

"I'm not worried, I've learned to take care of myself, didn't have much of a choice."

"Why would such a lovely lady like you have to learn self defence?"

"Because things like you have a habit of trying to take advantage of people like me, and it had to stop somewhere." Sophia's answer was accompanied by a blade slotting between the vampire's ribs and into the heart. When the vampire's body jerked again, Sophia shoved him over and retracted the blade back into the gauntlet hidden under the fancy sleeve, happy that the bullet will have finished the job. Eve emerged from her shadows to wander over – surprisingly casually, she'd come to the same conclusion as Sophia – and put another bullet in the vampire's skull for good measure.

"That went well," she stated, looking down at the corpse that had stopped twitching.

"Definitely. We've even got time to still enjoy the fair for what it is."

"Shall we then?" Eve offered her arm and Sophia took it.

"We'll go and tell the crime scene team about the corpse on the way back to the festivities," Eve nodded and led Sophia into the shadows again, the corpse in the middle of the floor proof of their odd method. Sometimes working like the assassins of old worked in their favour, no-one expected it anymore.
