The Angel and the Devil

Chapter 1

I was 15-years-old when my family died in that fire that SHE started. She took my family away from me. She took my mother. She's the one that made me put my protective wall up because I thought she loved me. She is the one that broke my heart for the final time. So I locked my feelings up except anger and hate. Yeah, anger and hate were the two feelings I held onto.
Anyway, so as always I head to work at 6:00am to get a head start on my cases and files. Oh um I'm a deputy at Beacon Hills Sheriff Station. I've been working here for 8 years. I joined the department to catch Kate, the one who started the fire in my family home. But I haven't had any luck... YET!
The sheriff, my boss, has a son that comes in at 11:00am to bring the sheriff his lunch. He's always wearing the same red hoodie and the same red and white converses. Okay so maybe I analyse this boy too much but there's something about him that every time he walks in, a little bit of my wall breaks, but I rebuild it real quick.
This Thursday Stiles (which is the boys name) came into the station with three bags of food. He went into his fathers office and came back out and and heads towards me. But I had to show that I didn't care so I put a plain expression on my face.
He came and sat down opposite me and smiles. I nod back, not showing any emotion. I don't understand, I've scared everyone in this town but yet this 19-year-old boy buys me food and is extremely close to me. He isn't afraid, I actually see love in his eyes when he looks at me.
So we sat there in silence eating our food, obviously I say 'thank you' we're eating in silence until Stiles looks at me and asks "Derek, isn't it?" He says pointing at my badge. I nod and he looks deep into my eyes, tilts his head and chuckles "you don't talk much do you? You always have your head in those files. What you looking into?" I chuckle a little but not enough for him to notice. I hand him the file and while reading it his smile slowly fades away.
He looks up and the emotion I now see in his eyes is sorrow. He looks back at the papers, tilts his head and his eyes widen "you've been chasing her around in circles." I look at him with a 'well nah I know that' expression and reply "yes Stiles, I know, thank you!"
"No! I mean you've been chasing her round in circles because you've missed a key detail." I look at him with confusion written all over my face. He puts the file on the desk and grabs a pencil and starts circling every letter that starts a new line and it spelt out:
Next target Sheriff Station 10th May at 6:00pm. We both lift our heads at the same time and panic fills our eyes. I pick up my phone, today is the 10th May and the time is 1:59pm and I calm down a little I look at Stiles point him to his dads office signalling that he should tell his father. He stands up looks at me and smiles, I nod back and he walks off to his fathers office.
