5 years ago.

Today's the day I've been waiting for for a long time. I have worked my ass off the finally get the promotion I've been wanting for over 3 years now.

I make my way to the bus stop, waiting for line 12 that goes straight to my work. It's about 5 minutes later when the bus finally arrives. I get in the bus and I'm about to sit down at the first avalaible seat there is. A girl, with the brightest blue eyes stares right at me, she smiles at me and gives gestures for me to sit down.

I nod at her and sit down next to her. She looks away but I see her looking at me through the reflection of the window. This makes me smile. I notice how beautiful the girl is. She has straight blonde hair that's about the length of shoulders. She has beautiful full lips and eyes that light up the whole world.

''Hey'' I say to her, hoping for a response.

The girl turns around to face me and smiles ''Hey. How are you?'' she asks me, seeming genuinly interested in how I'm doing.

''I'm a bit nervous to be honest..'' I admit, I take a deep breath before talking again ''I'm hoping to get a promotion today. But how are you?''.

''That's awesome'' the girls says to me. ''I'm doing fine. Just going to visit my parents for the weekend''

''Nice. I can't wait fort he weekend'' I tell her.

I want to continue the conversation but I can't because I already arrived at my destination. So I get up before facing the girl one more time ''It was nice meeting you…? I'm so sorry. But what's your name? I ask a bit shy.

The girl gives me a hint of a smile before answering ''I'm Clarke. It was nice meeting you as well'' she says to me.

''Lexa'' I add. ''I'm lexa'' I say before turning around leaving the girl in the bus behind.

I get out of the bus and start making my way to the bus. Not paying any attention to my surroundings because the girl from the bus has taken over my thoughts. Something about her made me feel something special. I couldn't exactly tell what it was, but she seemed so genuin, caring, loving.

My thoughts are interrupted when I arrive at work and the security guard greets me ''Good morning, miss Woods''

''Good morning, Titus. Enjoy your day'' I tell him before heading inside.

I make my way to the conference room on the 3rd floor. I walk inside to meet all my colleagues inside.

''Good morning'' I tell them before sitting down next to Lincoln. Lincoln is one of my best friends. We met in College and became close friends right from the start.

''Hey Lex'' Lincoln says to me.

I turn around facing Lincoln ''Hi, nervous?'' I ask him.

He nods but remains quiet because of our boss who walked into the room.

''Good morning chief'' everyone says before turning their attention to the papers in front of them.

''Good morning everyone. Thank you for coming today. I've got some exciting news'' the chief tells us.

''I need someone to go undercover..this is a big chance. The first person to succesfully finish the mission will be the next chief of the police department. But let me remind you of one thing, this mission will require everything of you. You will have to give up everything, your life, your own identity, everything'' the chief admits.

I look around the room seeing my colleagues their reactions. I notice how scared some people up. Giving up your life to go undercover is a big thing. We all know how dangerous it can be.

The chief interrupts the silence in the room ''Any volunteers? he asks.

''Me'' I say. I'm not even thinking about what's at stake. Because I know I've wanted to be the next chief for so long.

''Very well. Miss Woods, meet me in my office in 10. The rest, get on with your work. Have a good day'' the chief says before walking out of the room.

It's about ten minutes later when I'm sitting across from the chief in his office.

''It's a bold move. I'm proud of you miss Woods. You've been one of our best dectectives. You deserve this chance. I think you'll be the one who will succeed'' he tells me.

''Thank you for trusting me, sir'' I tell him.

''Anytime miss Woods. So let's talk details''.

I nod and remain silent for the next 30 minutes. The chief explains every detail of the mission. I didn't know how big this was until I heard the name Wallace Cage. Wallace Cage is one of the most notorious hit men in the city.

It's about an hour later when I'm leaving the building behind. I'm starting with my mission right away. I am not Lexa Woods anymore. No, my new name, well my undercover name is Alexandra Trikru. An foreign exchange student from Germany. I don't know why this suits me but I think it has something to do with the fact that I'm only 26, and one of the youngest dectectives from the Polis City force.

I take the train to south east part of the city to get to my new appartment where I'll be living for a while. My first job is to track down a few of Cage his associates. Apparently he has a huge network all throughout the city. The chief told me explicitely to not trust anyone.

I arrive at a big appartment building about 15 minutes later. It looks old, but somehow peaceful. I take the stairs to the third floor until I'm standing in front of appartment 111.

I open the door and walk into the appartment. It's empty except for an old couch and a tv that appears to be broken. The kitchen is nothing more than two cabinets, a stove and a small fridge that's making a lot of noise. It's not much, but it's enough for me. I've lived in worse places.

I am about to sit down when I hear a knock on the door. I grab the gun from the table and put it in my back pocket of my jeans before rushing to see who's at the door.

I open the door, while holding on hand on the gun. I can never be to careful.

''Can I help you?'' I ask with a serious tone in my voice.

''Ehm yeah..'' the person tells me.

But before I can say anything else she looks up and is clearly taken by surprise to see me standing in front of her ''Lexa?'' she asks surprised.

I take in the girl in front of me. I recognize her beauty immediately. It's the girl from the bus.

''Clarke'' I say surprised.
