The Serial Killers (Complete)

That's when I saw him. A man, who was clearly a man, stood hidden partially by a tree, the midafternoon sun silhouetting him. His face was covered by a burlap sack with holes for eyes and a dripping black line where the mouth would be. Below that he wore a black tux, spattered with red, a Slenderman.
He cocked his head to the side and we stared at each other for a breath. In the next, he was raising his right hand and waving the dripping, crimson blade as if welcoming us to hell.
