This is an unusual novel with more than one story interpolated within the overall account of the fall and rise of David "Pudd'nhead" Wilson. His story is that of a would be lawyer who has a clever remark of his misunderstood, which causes locals to brand him a "pudd'nhead" (nitwit). His hobby of collecting fingerprints does not raise his standing in the eyes of the townsfolk, who consider him to be eccentric and do not frequent his law practice in Dawson's Landing. How he overcomes this distinction holds the novel together.
There are at least two other stories that are interposed with his. In the first, A slave named Roxy who is one-sixteenth black and majority white, while her son Valet de Chambre (referred to as Chambers) is 1/32 black. Roxy is principally charged with caring for her wealthy and inattentive master's infant son Tom Driscoll, who is the same age as her own son. After fellow slaves are caught stealing and are nearly sold "down the river" to a master in the Deep South, Roxy fears for her son and herself. She considers killing her boy and herself, but decides to switch Chambers and Tom in their cribs to give her son a life of freedom and privilege.
In the other thread, twin Italian noblemen visit Dawson's Landing. Tom quarrels with one. Tom robs and murders his wealthy uncle, and the blame falls wrongly on one of the Italians. From that point, the novel proceeds as a crime novel. In a courtroom scene, the whole mystery is solved when Wilson demonstrates, through fingerprints, both that Tom is the murderer and not the true Driscoll heir.
While this is not the best of Twain's works, it has redeeming features and is notably one of the first novels to use the evidence of fingerprints in solving a judicial case.
