Why there has to be always dark and only one hope of that light stand dangling above your head , my mind was shivering for the thought that if they found out my sister is not really dead...
My mind my racing now ,sweat beads have started forming on my forehead ,I was just trying to adjust my eyes to that dim light hanging from above and swinging like pendulum but I heard the cracking of door and from there appeared a figure and it shut the door roughly making a loud noise.
The first thing I noticed was his eyes which were staring at me like ,I was a prey and he was the predator and then he grabbed me by my hand and made me stand and started walking in my direction slowly , I was just making my way as far as possible from him but my back hit the wall and I gasped as his hand reached my shoulder and he pressed his body against me . Without wasting a time he whispered in my ear "Let's do it your way, tell me about S.F and leave otherwise I will make your life living hell.",this made me realize that I'm trapped now and nodded my head as answer and he had a half smile on his face and my plan was definitely working, he motioned me with his hand to sit and he turned this was his mistake and I just took the gun from his back pocket and hit him hard on his head that his consciousness was gone .
This is to be done in my way then so be it, I was out of that damn facility in not more than 30 min I could hear sirens blasting and the helicopter noise but little did they know ,how I really was?? A scientist or a criminal.
