When the doorbell rings, it's not a knock at the door, but a clatter at the switch. It's the doorbell to the room where he hid from the killer. He's worried that someone is in the room, but he can't find anyone there. He asks the doorbell man if he saw anyone when he went upstairs, and the man says he didn't. He tells him that he saw his sister enter the room before him, and that he knows that she is selfish, greedy, and a scornful person. The doorbell man says that the street lamp is fine, but the wattage of it is too high, which causes too much heat. He suggests that they replace it with a more energy-efficient one.
