Dr. Peabody (the only character who appears in all of Faulkner's first three Yoknapatawpha novels) is the Jefferson doctor who pays a home visit to Addie twice, the second time when she dies. He is a large man, “weighing two hundred and twenty-five pounds” (42); in order to climb the hill to the Bundren house he must be hoisted up with a rope. The two chapters he narrates in a colloquial storytelling manner reveal his bemusement at the antics of the Bundrens - especially Anse.
