The Mask.

Some say it was a myth. But I experienced it first hand. Gather round children, for this is a story about a man they called the mask. It was the fourth of February 1998, A Partly normal boring day in New York city. When we first met him..
Standing on top a large building near a park. Cops gathered as a girl desperately cried for help as he dangled her off the roof by her hair in one hand. In the other He held a knife."Let the girl go and we won't shoot!"one of the cops demanded in a voice like silk the mask responded with"as you please" as he dropped her off the building. The cops hadn't the time to get a blanket to catch her with so they watched as she landed on her neck and die. When they'd adverted their attention he'd disappeared like a shadow melting into thin air. That was just the first attack.The attack that stuck out most was his fourteenth one. He had a cycle.every two weeks he'd strike leaving hints of where'd he be next the first hint was his knife.He had attacked a steak restaurant after the girl. But on the fourteenth attack he broke cycle and left a much bigger hint. He walked into a bar and began to flirt a unlikely woman took to him rather quickly. He offered her a drink he'd dosed with poison. He stood up and locked the door swinging around on his heel to pull out a knife. He could of brought a gun but he wanted to watch them suffer.The girl couldn't let out a scream before he'd slit her throat and watched the blood drain from her neck.A man in his forties yelped as the mask turned to face him hands covered in blood. He then took the man by the neck and slammed him into the window of the bar breaking the glass and sending shards everywhere including the mans face. Then a woman who was a stripper there followed he made sure to kill the bartender slowly"Here's your tip sir"he said with a purr as he stepped on the bartenders throat squeezing the life he had left out of him.The mask then wrote up a nice letter and left.The cops came only moments after he'd left to discover the horrid slaughter house this bar had become.He had strung intestine from two stools with the note between them he'd also sat up the people as if they were still alive. When the cops opened the letter it read
"If it's in a park,or if it's in a bar
you can't get rid of the Mask.
He wears a mask
he's tall and black
but that's how they describe him.
A rumbling sound, than three sharp stabs.
you better run,
Your stomachs open.
and your honestly hoping'
that he won't hear a sound
but that's when you know that he's around.
you have an itch under your nose
and that's just how the story goes.
So close your eyes and count to ten
better hope you don't wake up again.
'Cause if it's in a park,or if it's in a bar
you can't get rid of the mask.
.... you'll see him if you look"
"It's the fuckin babadook poem."one of the cops said"yes Mr.Wells but he's put a twist. This is his next hint.
