"A Rose for Emily" is a short story that was written by William Faulkner. This story shows a southern gothic approach. In one of the scenes, what people discovered when they force open the door to the room above the stairs was a fancy room, and a dead body. The dead body was Homer Barron. It was Emily who killed him and kept him there.
They get Haymitch to take them seriously when they are getting threats for Snow by telling him, and to survive in the quater quell by taking away his liquor.
Correct as you have it. You have two independent clause joined by a semicolon and a conjunctive adverb (therefore). Those go in the order clause/semicolon/adverb/comma/clause, just as you have them.
