Here is a couple of Character Overviews. See the link below for further information.

Charlie Biggs
Charlie Biggs is a big, fifty-year-old black man. All his life he has been timid and submissive, but he finally learns to stand up for himself when he kills his employer, the abusive Beau, who is going to shoot Charlie. After the killing, Charlie hides for a while but finally realizes he must come back to face up to the consequences. He believes that by his actions he has finally become a man, and he insists on being called Mr. Biggs. He is killed in the shoot-out with the lynch mob.

Fix Boutan
Fix Boutan is the father of Beau. For many years he and his family and other like-minded whites have been able to take the law into their own hands. They have a long history of beating, killing, and abusing black people. As everyone expects, Fix wants to go to Marshall to lynch the killer of Beau. But two of his sons, Gil and Jean, oppose him, and Fix calls the lynching off. He says that the family must act as one, and if they disagree, he will not act. Fix says that he never wants to see his sons Gil and Jean again, but at the end of the novel there is a hint of reconciliation between Fix and Gil, as they sit together in the courtroom.

Candy
Candy is the strong-minded, independent, thirty-year-old niece of Jack and Beatrice Marshall. Her parents were killed in an automobile accident when she was five, and she was mostly raised by Miss Merle and Mathu. Her boyfriend is Lou Dimes. Candy is small and thin, with close-cropped hair. She wants to protect Mathu, and she insists that it was she who killed Beau. It is also her idea to summon the men to bring shotguns and empty number five shells, so that they can all claim to have killed Beau. When Mapes arrives, Candy is vigorous in her defense of the black men, and contemptuous of Mapes. Later, she becomes resentful when all the men want to discuss the situation in private. Mathu tells her to go home, and Lou bundles her into the back seat of her own car. In the courtroom scene at the end of the novel, Mathu asserts his independence from her, while she and Lou are reconciled.
