Black Alice is a novel by Thom Demijohn (Thomas M. Disch and John Sladek), written 1968.
During the Sixties, in Virginia, while the blacks fight for their civil rights, a white young girl is captured in Baltimore. The little Alice Raleigh, eleven years and blonde like corn, and heiress of an immense fortune, is kidnapped with a ransom of a million dollars. Her kidnappers, trying to make her invisible to the police officers and the federal agents, manage to brown her skin and her hair. They sequester her in a house held by an old black woman, near Norfolk. Slowly, Alice adapts herself to this surprising life, completely new for her. She eventually discovers who is the real instigator of its capture.
