chunk: Twin Italian noblemen visit the town to some fanfare, and Tom quarrels with one. Then at last, desperate for money, Tom robs and murders his wealthy uncle and the blame falls wrongly on one of the Italians. Thereafter the story takes on the form of a crime novel. In a courtroom scene, the whole mystery is solved when Wilson demonstrates, through fingerprints, that Tom is both the murderer, and not the real Driscoll heir.
  The book ends in bitter irony. Although the real Tom Driscoll is restored to his rights, his life changes for the worse, for having been raised a slave, he feels intense unease in white society, while as a white man he is forever excluded from the company of blacks.
  In a final twist, the murdered man's creditors successfully petition the governor to have Tom's death sentence overturned. Now that he is shown to be black, he is a slave, and as such, is rightfully their property. His sale "down the river" helps them recoup their losses.
