Tom and Huck go to the graveyard to try out some superstitious experiment. There they see Dr. Robinson, accompanied by Injun Joe and Muff Potter.
Injun Joe then brings up a point about something the Doctor had done many years before, and says he wants revenge. Dr. Robinson then strikes him to the ground.
Muff Potter was upset that his partner was hit on the ground, and attacks the Doctor. The doctor picks up a board and hits Muff Potter unconscious. Injun Joe, during this time, however, had picked up Muff's knife and took the opportunity and stabbed Doctor Robinson
