is portrayed as the embodiment of human folly. His weakness for gambling leads him into debt. After his father's death, he is adopted by his uncle Judge Driscoll, who frequently disinherits him, only to rewrite his will again to include him. Capello twins Luigi and Angelo Capello, a set of near-identical twins, appear in Dawson's Landing in reply to an ad placed by Aunt Patsy, who is looking for a boarder. They say they want to relax after years of traveling the world. They claim to be the children of an Italian nobleman who was forced to flee Italy with his wife after a revolution. He died soon afterward, followed by his wife. One of the twins is said to have killed a man. One of the twins kicks Tom because he made a joke about him at a town meeting. As a result, Tom's uncle Judge Driscoll challenges Luigi Capello to a duel. David "Pudd'nhead" Wilson Wilson is a lawyer who came to Dawson's Landing to practice law, but was unable to succeed at his law practice after alienating the locals. He establishes a comfortable life in the town, working as a bookkeeper and pursuing his hobby of collecting fingerprints. Although the title character, he remains in the background of the novel until the final chapters. Each chapter begins with clever quotations from Pudd’nhead Wilson’s Calendar, a project of Wilson's which endears him to Judge Driscoll but further confirms everyone else's opinion of him as a pudd’nhead.

More importantly, he found that the serious tone of the story of Roxy and Tom clashed unpleasantly with the light tone of the twins' story.

So I pulled out the farce and left the tragedy. This left the original team in, but only as mere names, not as characters. The characters
