He cleverly persuades his friends to trade him small treasures for the privilege of doing his work.Tom falls in love with Becky Thatcher, a new girl in town, and persuades her to get "engaged" by kissing him. But their romance collapses when she learns Tom has been "engaged" previously to Amy Lawrence. Becky cries for a great deal of time until the other students begin to notice, and she becomes embarrassed. Shortly after Becky shuns him, he accompanies Huckleberry Finn to the graveyard at night, where they witness a trio of body snatchers, Dr. Robinson, Muff Potter, and Injun Joe, getting into a fight in which Robinson is murdered by Injun Joe. Tom and Huckleberry Finn swear a blood oath to not tell anyone about the murder, as they feel that if they do, Injun Joe would murder them.
