Martin’s book provided the disturbing, destabilizing experience of being thrust back into a period of intense racial hatred as if it were happening in real time. It is one thing to recall famous photographs of police dogs set loose on child marchers during the civil rights movement, or of lynch mobs picnicking around a still-hanging corpse. It is another to be confronted with a meticulous, day-by-day reconstruction of relentless bigotry in action. Nearly every page of Martin’s book brings to life the atrocities inflicted upon Black children and parents, and a handful of white allies, in the town of Clinton, Tenn., during the year after its high school desegregated under a federal court order.
