chunk: Puddn'head Wilson moves into the background as the focus shifts to the slave Roxy, her son, and the family they serve. Roxy is only one-sixteenth black, and her son Valet de Chambre (referred to as "Chambers") is only 1/32 black. Roxy is principally charged with caring for her 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 further south, Roxy fears for her life and the life of her son. First she decides to kill herself and Chambers to avoid being sold down the river, but then decides instead to switch Chambers and Tom in their cribs so that her son will live a life of privilege.
