During the antebellum south on the western shore of the broad, mighty , muddy Mississippi River 2,350 miles long and miles wide, in the golden era of the steamboats ( numbering an astounding 1,200, vessels ) feed by more than a dozen tributaries, they continuously went up and down those waters and entered other streams too. A small , tranquil village named Dawson's Landing stood, half a days travel by boat below St. Louis in the state of Missouri not an important place mind you, yet when an intriguing stranger, Mr. David Wilson arrives from a distant part of the country, seeking to practice law here things pick up, he hears loud barking from an unseen dog on his first day, annoyed greatly the new lawyer tells some curious leading citizens that if he owned half the animal he Wilson would kill it... Shortly afterwards the influential people in town gather and discuss those quite remarkable silly words by the newcomer, after a short conversation come to the unanimous conclusion this Mr. Wilson is a pudd'nhead (translation, an idiot) the unfortunate man quickly receives that nickname Pudd'nhead, his high hopes for being a successful lawyer collapses , no one will hire this obvious moron...At about the same time two look alike children are born both boys, one to Percy Driscoll, Thomas Driscoll, from a prominent family in old Virginia his poor wife soon expires in the effort, another from a black slave the beautiful Roxana ( no surnames given them) her son, she names Valet de Chambers. The interesting thing is Roxana is white in appearance, only one -sixteenth black which makes Chambers one -thirty -second he had a white father however one drop of blood , will change your life. Roxy who takes care of the children, is afraid she and her baby will he sold and sent down the river to a fearful fate , by her owner Percy Driscoll and switches children Thomas becomes Chambers and Chambers , Thomas, nobody notices the difference, still one has a fabulous life of wealth and privilege the fake Tom, ( doesn't known he's black) is a cruel vindictive, coward the real Tom a kind, generous, forgiving , brave man suffers misery , humiliation and beatings frequently by the impostor yes, treated like a slave.... Mr. Wilson has plenty of time for a hobby between doing odd jobs in accounting and surveying to survive, virtually unknown to the public fingerprinting, a system that can identify anyone by the patterns on the tips of your fingers, he takes the prints of all on a glass in the village, the amused citizens think just another eccentricity of the addle- brained man, then a mystery happens, local robberies occur in the quiet, peaceful town . More fascinating the enigmatic Italian twins , Luigi and Angelo Capello nobles they say, somehow find this tiny community through a newspaper ad and rent a room, the entire Dawson's Landing is thrilled some excitement finally here, later duels, a murder and an old woman who keeps being seen and vanishing at the site of further unexplained, petty robberies ...A fine story that starts as a comedy and then unexpectedly turns serious, telling and showing the tragedy of slavery... Mark Twain wrote about this evil institution and reached the American conscience.
