What's a street vigilante?

It's someone who stops crime. An ordinary Joe or Jodess who takes justice into their own hands, who defends the streets from evil.

What's a beat down?

What Jane Rizzoli lives for, and the beginning to a very strange story.

She had never run so hard in her life. Every step felt like a thunderous stomp. Heaving, gasping for breath, she skidded across the street, the grey hooded streak disappearing into an alleyway in front of her. She stepped out, swinging herself around the corner. The man had hit a dead end; in front of him was a chain link fence. The teenage girl was not but a few yards away. The gun was beginning to slip from his hand.

It was near the end of the chase. The masked man could tell that little bitch was going to get him.

He turned around, gun raised. Jane's eyes widened, her feet felt lighter than they had all day. His finger tightened around the trigger.

Click.

Confused, he tapped the trigger again.

Click.

Click.

Click.

She was smiling, sprinting towards him. Yes, he realized, he was fucked. Running seemed out of the question, the girl had had the best of him.

The police sirens were getting closer, but were they were too late. Jane had to dish out her own justice. She tackled him to the ground, scratching her arm on the cement. He grabbed onto her shirt with his sweaty hands and quickly lost his grip. Her hand found his wrist and she twisted it, so that she was straddling his back.

CREAK

His arm was breaking. Jane had never been so proud. The aching in her muscles began to subside, her pride now making her body glow. She swept her wet, black, curly hair from out of her eyes.

Behind her, police cars came to a screeching stop. "Hands behind your head!" Very slowly, the head of the operation approached her. His gun was resting on his opposite wrist, his arms were tense and his finger was resting on the trigger. "Jesus, Rizzoli," he took a sigh of relief. He lowered his gun and raised a hand in the air. It was like a bag of wind being released, the officers lowered their guns. "What have you gotten yourself into?" Jane knew that voice, kind of deep, caring, soft… Korsak. The man beneath her squirmed as she pushed herself off of him. She took a deep breath, her legs hurt as she turned to face the overweight, bearded Detective Korsak. "Rizzoli, I really wish I didn't have to do this. Cuff 'im."

Jane smiled. "Serves him right-" An officer walked towards her, hand cuffs in hand. "What? You can't-"

"You interfered in an undercover operation, that's an offense. Sorry, kid, but we have to take you in."

The look on her face caused Korsak to shutter. It was not anger or sadness, but shock. She had been betrayed, she felty betrayed. Her eyes were wide, her body rigid. She could not believe it. After all the chasing, and then finally catching the guy, she is punished? It didn't seem right, and the more she thought of it, the more anger came to her. The officer fastened the handcuffs around her wrists, and was lead into the police car. Her eyes never left Korsak's face.

"Wait here until we come and get you." Korsak patted Jane's boney back and disappeared into the offices behind her. She adjusted her tank top, uncomfortable in her current state of mind. It was never her fault she had happened to have walked in on a massive drug trade. She was doing what she thought was right, and she stopped something awful from happening. So why did she end up here?

Jane was sitting in the lobby of the Boston Police Headquarters, in a line of blue-plastic chairs against some offices. It was mostly empty in the main lobby besides a few odd looking maintenance workers. All of the on-call uniforms were sent to clean up Jane's mess. How could she have messed up so bad? All she wanted to do was help, and there was no way the police could get there in time. She was doing Boston a favor, really, a big stinking favor. That's it, she was riled up now. She was going to get those sons of-

Besides Jane was a sniffling girl, around seventeen or eighteen. She had a baby face, like Jane's brother Frankie, but she had a tiny body. Her blonde hair covered her sour face. Jane tried to ignore her, but the a sick feeling tossed around in her conscience.

Finally, Jane asked, "Are you okay?"

"No." The girl said.

"Okay." She turned away from the girl, and tried to get back to being angry. But her attention was caught once more.

"It's just that I burglarized."

Jane raised a curious eyebrow. "You did what now?"

"Burglarized. It's the past tense form of the action verb burgle. It comes from the stem to burgle-"

"So you stole something?"

The girl wiped a tear from her eye. "Yes." Jane hated it when people beat around the bush.

"How'd you get caught?"

"I didn't, I'm turning myself in." The girl scooted closer to Jane, and looked up at her. Jane could see that she was quite pretty; she had one of those sweet faces, one of the faces that seemed so much like home. "I didn't realize it, but I-I accidently forgot to pay for it at the store."

Jane tried not to laugh. "Are you being serious?" The girl broke into sobs. "Don't do that, uh." Jane scooted to the chair next to the girl. "Uh, okay." As Jane lifted a hand to pat her back, the girl felt into her arms. "Hey, it'll be okay, or something." Jane ran her hand over her blonde hair. For once in her life, she had no idea what to say. "They won't arrest you for burger-bugle."

"Burglary!"

"Yeah, that."

The girl looked up, wiping her last tears against her hand. "Maura," she said. Her body stopped heaving with sobs and she began to straighten her back. "Maura Isles," she extended a wet hand.

Jane leaned away and kept her hands to her side. "Jane Rizzoli." She stared at the hand extended to her, a sarcastic smile on her thin lips.

"Oh," Maura looked down at her hand, embarrassed. "Sorry, I didn't realize…" She put her hand down and her face turned red.

The door to the office opened, and Korsak stuck his head into the lobby. "Rizzoli, he is ready to see you now. And you- uh," it was a face he did not recognize.

"Maura," Maura said.

"Okay, Maura, why don't you come in too."
