This PowerPoint presentation summarizes the characters and plot of Mark Twain's novel Pudd'nhead Wilson. It shows that Roxana, a slave, switched her newborn son with her master's son. Years later, when the boys' identities are revealed, Thomas Driscoll (who is actually Valet de Chambre) is arrested for murdering his uncle. Pudd'nhead Wilson is able to prove his innocence using palm print analysis, revealing that Valet de Chambre and Thomas Driscoll had been switched as infants.
