The Housemaid's Secret

Tonight, I will be murdered. Lightning flashes around me, illuminating the living room of the small cabin where I'm spending the night. It all started with a simple cleaning job. And now it might end with my blood being mopped off the cabin floor. And then I hear the footsteps, growing closer. It's hard to judge, especially since everything is so dark, but I'm pretty sure there is now somebody here with me.
All the hairs on my neck stand up. I am no longer alone. My heart sinks into my stomach. I have made an incredibly bad judgment call. I have underestimated an extremely dangerous person. And now I will pay the ultimate price.
