Meuchelmörder

Why did this word pop into my head? “Meuchelmörder” what did it mean? There had to be a reason why I’ve just learned this word.

The doorbell ranged.

“This is the cops, we need to talk”

“uh….. Just a minute”

I walked over to the door, unsure on what to do. I opened the door slowly, and there was no one there. I closed the door and walk backed quietly.

“Sir! This is important!” said the “cop”

“Your not there!” I said walking toward my bat.

“What are you talking about?” said the “cop”

“I’ve opened the door already, and you weren’t there” I said as I was locking the door.

It was silent after that, maybe I was still asleep.

A note was on the floor next to the bed it read.

“At 8:00 the cops will arrive, but won’t be there. Don’t worry about that, right as you read this note a Meuchelmörder is coming after you. You need to get out of there now!

PS,

What the fuck are you still reading this for?”

A Meuchelmörder? That’s the word, what did it mean? What is coming after me?
