Sixteen years after Richard Hill testified in court that he crouched under the tablecloth and saw Henry Clayton rape his white momma and murder her and his black poppa, a DNA swab earns the prisoner a pardon and his freedom. Returning to Red River Falls, Clayton claims that he has been reborn and offers to help Hill, now a patrol officer, identify who really killed his parents. Hill, who relives the family horrors every day, doesn't believe him. But how can he prove DNA evidence wrong?

Here, in Ask the Brains, Part 1, they’ve compiled some of the best and most interesting inquiries about the human brain.
