As the grand jury convenes, Byron joins the gathering crowd downtown, self-conscious about his new role as the champion and savior of another man’s woman. He returns to the boardinghouse where Mrs. Beard has packed and stored his remaining items. He is finally able to meet with the sheriff and arrange to have Joe Brown taken out to the Burden farm later that day. Hidden in a clump of bushes, Byron watches the deputy push Brown into the cabin and close the door. Byron gets on his mule, loaded with his belongings, and rides off in an attempt to start a new life elsewhere. On the crest of a hill, he turns to see the Burden property below and notices Brown run out of the back of the cabin and make a mad dash for the woods. Turning the mule around, Byron gallops off in pursuit.
The narrative then shifts to Brown’s perspective as he is escorted from the jail and taken to the cabin. Once inside, shock, rage, and fear descend on him when he sees Lena and his newborn son. Brown lies, saying that he sent Lena money to come meet him but that he did so through an unreliable source. Realizing that he is trapped, he opens the cabin’s rear window and escapes. Reaching a shack, Brown pays a young man to bring a hastily scrawled message to the sheriff requesting that the courier return with the entirety of the reward money.
Brown is seated and waiting when Byron comes upon him. Byron gives Brown the chance to rise to his feet, and the men fight, Brown eventually getting the better of his smaller opponent. When Byron finally rises, bloody, from the grass, he walks to a railroad junction where he sees Brown jumping on a passing train. Headed back to town, a man in a wagon stops beside Byron to tell him that Christmas has been killed in town within the past hour.
The district attorney, Gavin Stevens, places the Hineses on the train for their return journey home and assures the elderly couple that their grandson’s body will be sent along the next day. It emerges that Joe Christmas was found hiding in Reverend Hightower’s house when he was recaptured and killed. A former schoolmate, coming to Jefferson to visit Stevens, steps off the train as the Hineses are boarding.
The account of Christmas’s escape and death is then told through the eyes of Percy Grimm, a young white supremacist with a zeal for the U.S. military. With a ragtag guard of American Legion members, he commands his men to patrol the town square and surrounding area. When Christmas escapes, Grimm commandeers a messenger’s bicycle and takes off in pursuit. Chasing Christmas to Reverend Hightower’s house, Grimm and three armed men burst in on the minister, who, taken by surprise, claims that Christmas was there with him on the night of the murder. Ignoring the preacher’s somewhat incoherent words, Grimm finds Christmas in the kitchen, where he shoots him five times and then, with a butcher knife, castrates him.
The recounting of Joe Brown’s trip to see Lena and his newborn son in the cabin epitomizes Light in August’s fluid sense of time and exploration of multiple perspectives. First, Faulkner offers Byron’s version of the proceedings, examining his murky motivations in wanting to reunite the child’s biological parents. Later, Faulkner retells the same event from Joe Brown’s point of view. The two separate accounts are then fused into a new and resulting action, when Byron witnesses Brown escaping via the cabin’s back window. Byron gives chase, and their showdown ensues. Though beaten, Byron emerges from the fight infused with a new purpose and willingness to assume personal risks he would never before have dreamed of.
