a/N Hey guys! So i'm really super excited about this story! It's been an idea I've had running around my brain for awhile now. I wanted to put the Preface and first Chapter out to see what people thought of it. It's definitely going to have a darker theme then my other Fic I'm writing right now called Right Side of Rock Bottom (if you haven't, go check it out!) but I feel like it's really good. Let me know what you think, should I continue writing it?!

Without any more introduction here's The Monster Within.

Preface

"I made you." He chocked out, rolling over to look into her cold, dead eyes. Blood was everywhere. "I made you, Mitchell. You're basically just a copy of me."

"I am so much more than a copy of you." As she spoke the words, she raised the gun. Her hands were steady. She couldn't help but laugh. Oh. the irony of the situation.

"Do it." He dared. There wasn't ever a flash of worry on his face, in fact he was smiling. It was almost as if he had always expected to meet his end this way, at the hands of Beca Mitchell. "It'll only prove how much of a monster you are."

"That's the thing, sometimes it takes a monster to destroy a monster."

Bang!

Chapter 1: Fletcher Jones

6 Months Earlier

"Hey kid," Beca walked up to the table that her younger sister had been sitting at, waiting for her. "Sorry I'm late."

"It's okay," Emily smiled at her as she sat down. "I got you your usual."

"Oh my god, thank you!" Beca practically moaned into her cup. "This is why you're my favorite sister."

"I'm your only sister." Emily deadpanned. She couldn't help but roll her eyes at her big sis.

"So, tell me, how's school?" Beca asked turning her full attention to her sister.

Emily was the only thing Beca had in this world. She was the reason why Beca did the things she did. Ever since Beca was 15 and Emily was 10 they only had each other. There parents had unexpectedly died in a car crash. With their death, Beca was left to protect and care for her younger sister and that's exactly what she did.

"It's soo good!" Emily practically squealed. "I met this guy the other day named Benji."

Beca stopped for a moment. "Benji? That's a weird name."

"Well his real name is Benjamin but he doesn't like it and he thinks Ben is too boring so he goes by Benji." Emily explained. "He's in my Psychology class and we just started talking yesterday. He's super nice and kinda dorky."

"Sounds interesting." Beca thought. "Are you two going to go out?"

"No… I mean he hasn't asked me so probably not." Emily explained looking down at the table.

"Why don't you ask him?" Beca wondered.

"I don't know… wouldn't that be weird?" Emily asked.

"What? Em, what are you even talking about." Beca asked. When had her little sister gotten this mentality. "It's not weird to ask someone out. Do you like him?"

"Yes."

"Do you want to go out with him?"

"Maybe." Emily confessed.

"Then ask him out!" Beca explained in an exasperated tone. Why the hell are you encouraging this? Do you want your baby sis to grow up?

"Okay," Emily nodded her head but still seamed to be thinking about it.

"Are you going to do it or are you going to keep thinking about it until you talk yourself out of it again?" Beca asked with a smirk.

"Shut up." Emily rolled her eyes. She hated how well her sister knew her. "I'm going to do it. I was just thinking of how."

"Try by saying Hey Benji, would you like to go on a date? That usually does the trick." Beca explained with a laugh. This got her a kick in the shines. "Ouch! Don't be a jerk." But she was still laughing.

Just then the door to the coffee shop opened and in walked to police officers. Both women, one had long blonde hair. She looked a little stern and kind of like she had a stick up her ass. The other was a cute redhead whose smile looked like it could be the answer to world peace. Beca couldn't help but notice her strikingly beautiful and perfect sky blue eyes.

"Beca… Earth to Mitchell!" Emily had been trying to get her sisters attention since the officers walked in.

"Yeah, sorry Em." Beca turned her attention back to her sister.

"So, how's work?" Emily asked. Beca worked as the assistant to the CEO of Nightline Clubs Inc. However, Emily knew there was something more to Beca's job. Beca would always tell Emily she was crazy whenever she brought up her suspicions but that didn't stop her from feeling that way.

"It's good. But Luke's been a pain in the ass lately." Beca explained. Luke Matthews that is. "But nothing super ground breaking has been happening.

Just before Emily could respond Beca's phone chimed with a text. She looked down to see who it was from.

Unknown: Your delivery has arrived.

Beca looked at her sister with an apologetic look. "Sorry kid. You shouldn't have mentioned work."

"You gotta go?" Emily asked, however she already knew the answer.

"Yeah," Beca stood up and walked over to pull her sister into a hug. "Go to all your classes today! I mean it, no skipping your writing classs!"

"Dang it Becs, really? It's sooo boring though!" Emily whined.

"Hey, just think if you fail that class because you aren't going to it you're just going to have to retake it." Beca pointed out. "I love you."

"I love you too!" Emily smiled at her sister. "Do you know how long you'll be gone?"

Sometimes Beca's job took her away from the city for days at a time. Once it was even a month.

"It's just a day thing." Beca smiled at her. "Pizza and crappy TV tonight?"

"Of course," Emily smiled brightly. "Is that even a question?"

"Perfect, I'll text you when I'm on my way home." Beca kissed Emily's cheek. "See you later kid."

"Bye." Emily smiled back, then she watched as Beca made her way out of the café. She couldn't help but wonder if Beca was ever going to let her in about her job.

The Guild

"What the fuck do you want, Phoenix." Beca called as she made her way into the shut down night club. They used it as a sort of homebase during the day. At night, they used it as a place to scout clients. The club was owned by Nightline Clubs Inc. so it was an obvious choice for them.

"I've got a job for you, Titanium." Phoenix came into view as she rounded the corner. Phoenix's real name was Luke, but you were never allowed to call him that while at the Guild. No one was allowed to go by there real names while here. Beca was known as Titanium to the members of the Guild.

He handed Beca a folder. She sat down on the black couch and opened the folder. There was a picture of a middle-aged man. He had graying hair, it was long, dark brown eyes, he was missing a few teeth and just had a really creepy look about him. Beca lifted the picture and began to read the information that was accompanied with it.

Subject: Fletcher Jonas

Address: 19 W Colonial Street Apt. 1

Crime: Rape of at least 3 women and 1 child

Client: Anonymous

Desired Action: Death

Requested Member: Titanium

Beca continued to read through the file. It disgustingly enough went in to more detail about this piece of shit. Beca could feel her blood boil as she read what he had done to those people. After finishing the file Beca looked up to Phoenix.

"So?" He asked with an expecting look on his face.

"I'll take care of it." Beca said with a chilling tone. Her eyes turned from the dark blue to an almost black. She was no longer Beca Mitchell, she was now the Assassin, Titanium.

"Go talk to Aussie about how you're going to carry it out." Phoenix ordered.

"Will do," Beca agreed. "Hey, we need to talk about Emily's security. I need you to check on some guy named Benjamin. He goes by Benji."

"Just go." Phoenix dismissed her.

"Dude, I'm serious." Beca protested. "I can't have her being in a relationship with someone that could possibly hurt her."

"We have bigger fish to fry right now!" Luke yelled. "Go get your man and then maybe we can talk about this!"

"Yes sir." Beca gave a fake salute and walked out of the room to go find the Guild's weapon specialist.

"Hey A." Beca called as she walked into the room.

"Titanium! How's it shaking?" A large girl came walking up to Beca, she had a giant ass sword in hand. Beca was a little worried, not because she thought Aussie would hurt her intentionally, but she had a tendency to get a little excited.

"Do you wanna put the sword down?" Beca asked her.

Aussie's real name was Amy, which wasn't actually her name either but that's what she went by in the real world anyway. She was from Australia and had a hugely impressive knowledge of weapons. She was in charge of the Guild's armory. Which usually meant that Beca got all the cool weapons because A liked her the best.

"Sorry about that." Amy smiled as she put the sword down. "So, what can I do for my favorite assassin?"

"I need the biggest syringe and needle you got." Beca explained. She knew exactly how she would handle this fucker.

"Ohh, what do you have in mind?" A asked as she walked Beca toward the medical section of the room. "What kind of poison do you want?"

"I don't need any." She explained as she took the supplies. A gave her a curious look. Then Beca explained exactly what she had in mind for Mr. Jonas.

Fletcher Jones' Apartment

Beca had been sitting in the dark apartment for almost an hour, just waiting for this scumbag to return home. She was sitting in the far corner, being hidden by the shadows. The door opened and in walked a very obviously intoxicated man. Beca had to study him for a moment but quickly confirmed that that was indeed Fletcher.

He made his way over the fridge and grabbed another bottle of beer before stumbling toward the couch. Fletcher fell onto it with a groan. Beca very quietly made her way around to the back of the couch.

She stayed still, waiting for him to inevitably pass out. Just as she suspected he downed his beer and was out within a matter of seconds. The sleeping pill she dissolved into it helped of course.

Beca filled the syringe with air, before sticking it into the man's chubby left arm. She slowly pushed the air into his vein. Within a matter of moments, he was dead. The excessive amount of air in his bloodstream had caused his heart to stop, almost immediately.

He never saw her, That's the thing, Titanium was never seen.

Beca checked his pulse to make sure he was dead. Confirming the kill she placed a small titanium 'T' on his chest. It was her signature after all.

She took a quick look around the room to make sure she left nothing behind that she didn't mean to. With that she walked out of the apartment, making sure she wasn't seen and made her way down the street.

She stopped at the nearest payphone and dialed the familiar number. It rang and then there was an answer.

"Yes." Blaze's voice came over the phone.

"Call it in." Beca stated and then hung up the phone.

She walked down the street and disappeared without a second look back to the apartment building.

Chloe's POV

Officer Chloe Beale and her partner Officer Aubrey Posen had just received a tip about a death in an apartment building. They had gone to check it out. After knocking on the door of apartment 1 and receiving no answer they decided to enter by force. After breaking in, they searched the dark apartment, guns drawn. Neither officer knew what to expect going in, they never did.

Just as Chloe went left, Aubrey went right. They both searched each part of the apartment until Chloe went to the couch.

"Body!' Choe yelled out and continued to search. They had to make sure everything was secure before examining the man.

"Clear!" Posen yelled out.

"Clear!" Chloe yelled after a moment. They both walked over to the couch. Aubrey made it first, so she checked him for a pulse but shook her head.

"Wait." Posen stopped and pointed at the mans shirt. There, on top of it, lay a small silver 'T'. This made Posen shudder and Chloe just stared intensely at it. They had found this exact same 'T' at multiple crime scenes across the city. They had been finding them for years.

"Damnit!" Posen grumbled. "When are we going to catch this freak?"

"I wonder what this guy did to catch their attention?" Chloe had noticed a pattern of 'T's killings. They only killed criminals. It was kind of a weird twist of fate. A murderer who murdered criminals.

"You don't recognize him?" Aubrey turned to look at her partner.

"No," Chloe took a better look at him while Aubrey called it in to get the forensics team in. But they already knew they weren't going to find anything. They never did.

"It's Fletcher Jonas, that guy that just got away with rape." Aubrey explained, and suddenly Chloe knew exactly who he was. He had just barely been found not guilty due to a technicality. It was pretty obvious the man had done it, but an officer messed up and Jonas' lawyers took it and ran with it.

"I guess it's not really a surprise then." Chloe said without thinking. She had pretty conflicting feelings about this 'T' person. Obviously, what they did was wrong, but they had also stopped a lot of really bad people from hurting someone else again. Chloe couldn't really blame 'T' for wanting justice for the victims.

Beca's POV

"Hey, Em." Beca called as she put her keys down and took off her coat. She could smell the pizza and was so happy about it.

"I'm in the Livingroom." Emily called back happy as ever.

Beca made her way into her apartment. She was greeted by her dog Marco. He was black, and fluffy. He came up to about Beca's knee.

"Hey buddy." Beca smiled at the dog and started to pet him. As she began to walk. he walked beside her. She turned the corner to see Emily sitting on the couch, enjoying a piece of pizza, and watching 13 Reason's Why. "Hey, how was your day?"

"It was good." Emily smiled. "I even went to my writing class."

"Well done!" Beca gave her an enthusiastic thumbs up. "Do you want a gold star?"

"Shut up!" Emily rolled her eyes. Beca sat down and Marco jumped right up and laid his head on her lap. "How was your day?"

"Pretty uneventful." Beca explained as she took a piece out of the box. "Do we have to watch this?"

"No, we can watch something else." Emily smiled at her. "I was just about to switch it to the nightly news actually, I wanted to see what the weather was going to be like tomorrow."

"Oh please, that's what you have a phone for." Beca laughed. "You just want to make fun of the two nimrods that do the reporting. What's their names?"

"Gail and John." Emily laughed as she changed the channel and sure enough their faces popped on the screen.

"It's a great day here in Atlanta!" Gail cheerfully explained.

"Did you finally get some?" John asked causing Gail to glare at him. Beca just rolled her eyes at the man. He was such a discussing man.

"Today, the Barden Bella's won their second straight national championship…" Gail started but suddenly stopped reporting. Then John took over.

"We are just getting word now that a body was found on Colonial Street. Rumor has it that its that of Fletcher Jonas. Let's head over to Jason on scene."

"God, did you hear about that guy?" Emily asked turning her attention to Beca.

"Yeah, everyone knows about this guy." Beca shook her head. She was still pissed about how he almost got away with it.

The reporter on the scene went on to explain how police had found the body about 20 minutes before. "It appears Mr. Jonas had a heart attack but there is cause for suspicion. However, we don't have any more information for now. Once we know more, we'll let you know. Now back to you Gail."

Just then Beca got a text.

Unknown: Well done, T.
