Twilight sat at her desk, a quill floated slightly above a blank piece of paper. She knew what she needed to write, she just didn't know how to write it. She hated getting writer's block, and it was driving her crazy trying to fight through it.
A quiet knocking at the door drew her attention away from the paper. "Come in." She said. The door slowly opened and Spike stepped inside, carrying a tray with a tea kettle and cup on it.
"Twilight? I thought I'd bring you some tea. You've locked yourself in here for days. What's going on?"
"Thanks, Spike." Twilight said, levitating the tray over to the desk and pouring herself a cup of the warm tea. "I'm fine really, I just don't know how to write this last part of my little project I've been working on."
"Alright, so what do you have so far?" Spike said, peering over Twilight's shoulder. She gasped and covered the paper with her hooves.
"No no no! Its not ready yet!"
"Twilight, you don't have anything, do you?"
"No. Unfortunately I don't. I wanted to make the ending a surprise for the reader, but I can't figure out how to do it. You've read all the other parts, so you know how it goes, All the evidence is pointing towards Miss Pennyhoof as the killer, but there is still some suspicion about Dr. Quicksilver. I left off at the detective about to reveal all the evidence and say who he thinks did it."
"So what's wrong with that?"
"I need it to be more of a twist."
"Here's an idea: how about I write this part?" Spike said, "Think about it, I know this story just as well as you do, I know what you're going for here, and you need a break."
"Alright Spike. Take over for me, I'm going for a walk." She said, getting up and leaving the room. Spike sat down and began to write.
The detective stood near the fireplace, looking into the flames as he smoked a pipe. He turned to the crowd of anxious ponies, all the evidence was coming together. He turned to one of the police officers in the room, calling to him.
"Good sir, lock the doors! The killer is in this very room!" There was a gasp as everypony looked around, wondering who it was. The detective smirked before gesturing with his pipe. "Yes, the killer is none other than..." He paused, building the tension. "ME!" He yelled out, pulling a knife from his over coat and slaughtering the remaining ponies one by one.
THE END.
Twilight turned to Spike. Then she began to laugh.
