The Chase

He is pursuing me! I can't figure out what he wants from me, but all I know is that if he catches me, I will die. How do I know that? I just have a feeling that it is true. The last time I saw him, he was way taller than me. He towered over me like a mountain of bones and flesh. Except for the red glow where his eyes are supposed to be, he looked perfectly normal. But there was this vibe around him that made me shiver with fear whenever he looked my way. There was no way to see his face, as it is always in the shadow of his lowered hat and high-necked trench coat. Whenever I was within viewing distance of this particular stranger, my body tenses up. My instincts tell me to run far away from him. What is he?
