Young Tom Sawyer’s mischievous ways greatly troubled his Aunt Polly. Late one night, Tom and his friend Bill Harper played “river pirate.” While on Jackson’s Island, they saw Injun Joe and another man arguing over a large black box. Joe stabbed the fellow and planted his knife on a third man who was asleep by the fire. At the court trial, Tom exposed the real killer and Joe escaped by smashing through a window.
