"The theme of this story: surreal caper. The main characters: stupid lawman and ugly inventor. The start of the story: temptation. The end of the story: death."
That could work. A surreal caper is kind of perfect for the Fear Mythos. Although why would a thief post on a blog? Stupid lawman could work, too, and ugly inventor. Temptation? Temptation for what? Hmm, have to think about that. But of course it would end in death.
If you keep going, every story ends in death. Cheery!
