Sade discovers that Rush has "cheated" while writing a composition called, "Our Friend the Dog". Although his actions probably can't be construed as the world's worst crime, he indeed sees the error of his ways once he reflects on the matter. He is ashamed that his integrity has been soiled.
He must re-do the paper, and this time the subject is his dog, Mr. Albert R. Johnson, and a trip they once took to Lake Bloomington.
The title is one I have provided purely for identification purposes.
