'My name is Darcy, I'm your nurse and I'm here to help you.' I repeat the words I've said so many times. Except this time, I don't mean it...If you saw me walking down the street, you'd think I was pretty ordinary - I wear the typical crisp, white nursing uniform, my hands are scrubbed clean and you'd have no reason to believe I was anything other than a good citizen. A good nurse.But looks can be deceiving. You shouldn't trust me - because I don't even know if I can trust myself.Now I stare at the reflection in the mirror - dark smudges under my eyes and blood on my hands - listening for the sound of police sirens.Because the truth is I had to do something terrible. I broke all the rules a nurse should follow. I wanted someone gone so badly. And now they're dead because of me.I'm looking over my shoulder everywhere I go because I'm sure someone knows my secret. Then when my home is broken into I know one simple truth: this isn't over yet...It's only the beginning.The police are the least of my worries now. But to save myself, am I going to have to kill again?
