Pete (known by his screenname "Properly Paranoid") works at a publishing house where a brown-bagged manuscript was delivered. Realizing that it would never be published, Pete took it back home and decided to put it up on the internet one chapter at a time.
In the story-within-the-story, the main character, "Norman," believes that there is a conspiracy centered around making his life miserable. It eventually transpires that he is caught between the Ivory Woman and the Vision, who wants him to help a certain writer find a wall.
