A/N: Hallloooo. I suck at writing long chapters, apparently. Because this chapter is so short that it could be me (Hehe :p). Anyways... Here is a little baby filler chapter for y'all because I'm brain dead from finals.

Thank you thank you thank you to Fan-of-Fandom279! I'm so glad that you're liking my little attempt at writing.

Chapter Four

"What do you mean she's coming for him? How could she possibly have heard about him from prison?"

"Heard about him?" Lestrade lifts an eyebrow and opens his mouth as if to continue questioning, but Sherlock quickly interrupts.

"He knows, John." Sherlock gives a slow nod in Lestrade's direction before continuing. "Who do you think was in charge of the investigation?"

John looks over at Lestrade and he gives a small, slow nod. "Right. He's known this entire time." He brings his eyebrows together as he turns his gaze back to Sherlock.

"I want to have some officers out here." Lestrade gestures in the direction of the windows. "Just in case she comes here."

"You didn't come here to ask for his help?" John sounds slightly skeptical as he questions Lestrade.

"Just to offer our help." Lestrade shakes his head as he stands from the chair. He then turns towards the stairs. "Well, not exactly an offer. The officers are already outside."

Sherlock rolls his eyes before something suddenly dawns on him and he hurries down the hall. John lets out an exasperated sigh as he turns towards Lestrade. He lifts his shoulders in an apologetic gesture and then nods as the man heads towards the stairs. Lestrade hops down the steps and then heads out the front door to the building. The sound of the door slamming can be heard as John crosses to the window. He nods to himself as he sees the officers spread out around the front of the building.

Sherlock lets out a breath as he pushes open the door and sees Kaley sitting on his bed. She looks up from the book she had been reading, a confused expression on her face. She blinks her blue eyes slowly as Sherlock walks over to her and then sits down. He places a hand on her knee and squeezes it slightly. Kaley looks down at his hand and then back up at his face as she makes a small questioning noise.

"Nothing. Don't worry about it." Sherlock speaks softly to her as he lifts his hand from her knee and then places it on her shoulder. He squeezes it and then leans forwards, resting his chin on the top of her head. Sherlock stays there for a moment before leaning back and looking her in the eye. "Why don't you tell me about your experiment?"

Kaley's face breaks into a wide smile as she begins to explain her experiment. She waves her hands around animatedly as she speaks, gesturing at her hair every so often to demonstrate her point. Sherlock watches with a fond expression as the young girl continues to explain, stopping every few minutes to ensure that her father is still listening and then continuing again. She rambles on for about an hour until she is interrupted by snoring sounds.

Kaley stops talking and laughs softly to herself. She stands from the bed and crosses over to the closet where a small case stands, holding all of her clothing. She pulls some out and then slips into the bathroom. When she steps back out, dressed in a dark blue hoodie, black jeans, and ankle boots, she makes sure not to alert John.

She tiptoes down the hall and then slips into the foyer outside of the flat. She pulls her phone from her pocket and checks the time. Just past noon. Perfect. She could head to the library and be back in time for a late lunch. What could possibly go wrong?

Kaley pops one of her earbuds in as she enters the library. She hums along to the song as she crosses the empty area at the front of the library and heads towards the section on psychology. She keeps glancing over her shoulder with a slightly confused expression. She is fairly certain that someone had been following her since she'd left 221B.

No. She's one hundred percent sure. This same brunette woman had been behind her throughout the entire walk to the library. Kaley sucks in a deep breath before ducking behind a shelf of books. She picks up a random book and begins to flip through the pages as she watches the woman out of the corner of her eye. Suddenly, the woman's disappears from her line of sight and Kaley looks around in a panic.

She shakes her head quickly, attempting to calm herself down. She could probably just be overreacting about this. Her father has always blamed her of having an overactive imagination. Kaley begins to nervously pull at a strand of black hair as she walks further down the isle of books. She examines the titles as she walks, not necessarily looking for a specific book, but simply examining those that were at hand.

The raven haired girl continues reading over the titles, having completely forgotten any of her worries from before as she completely emersed herself in finding a book. She hums along to another song, foot tapping against the ground. She stops for a moment to pick up a book titled "Sociopaths, Psychopaths, and More" and gives a small laugh. She reads the small blurb at the back of the book and then sets it back down.

"Is the book not to your liking?"

Kaley whips around at the voice coming from behind her and turns towards the sneering face of the brunette woman. She attempts to back away from the woman, but she suddenly feels a hard object hitting her across the back of her head. She stumbles forwards, falling onto her knees and letting out a terrified squeak as she slowly loses consciousness.
