Pudd'nhead Wilson is a novel by American writer Mark Twain. Its central intrigue revolves around two boys—one, born into slavery, with 1/32 black ancestry; the other, white, born to be the master of the house. The two boys, who look similar, are switched at infancy. Each grows into the other's social role.
