Here are some foreshadowings of the discovery of Homer Barron's body:
* The smell: Throughout the story, there is a persistent, unexplained odor coming from Emily's house. This is the first indication that something is amiss.
* Emily's reclusiveness: Emily becomes increasingly isolated and withdrawn, refusing to leave her house or interact with the townspeople. This suggests she is hiding something.
* The arsenic: Emily purchases arsenic, a poison, from the druggist. This immediately raises suspicion and is a clear foreshadowing of a potential crime.
* The "strange" men: Emily is seen with a series of "strange" men, implying she might be using them for a nefarious purpose. The townspeople gossip about these men, further building suspense.
* Homer's disappearance: Homer Barron, a construction foreman, disappears from the town after his last visit to Emily's home. This disappearance raises the obvious question of what happened to him.
* The wedding plans: Emily buys a wedding outfit and refuses to believe that Homer is dead, even years after his disappearance. This suggests she might have kept him with her.
* The silver hair: The townspeople notice that Emily has started to develop silver hair, indicating that she is aging. This is significant because it shows she has continued to live a relatively normal life for many years since Homer's disappearance, suggesting that Homer might be deceased and hidden in the house.
It's worth noting that Faulkner is a master of subtle foreshadowing. He doesn't explicitly state that Homer is dead, but he carefully lays the groundwork for the reader to anticipate the gruesome discovery that awaits at the end of the story.
