One night, Tom goes with Huckleberry Finn, the town drunk’s son, to the graveyard to try out a “cure” for warts. When they arrive there at midnight, they see Injun Joe murdering Dr. Robinson. The murderer blames his drunken companion Muff Potter for committing the crime and in addition to that, Injun Joe’s accomplice gets arrested the next day. Because Tom and Huck are afraid of him, they swear not to tell anybody about what they have seen.
