The red room
The narrator tells the story in a way that comes across is that the only person remotely sane is he. Three of the elderly people in the story fit into the atmosphere of the house. The whole scene is dark and gloomy with only the fire burning which warmed up the house and environment. They all have a monstrous appearance, which seems somewhat in human, which creates doubt in his strong disbelief about ghosts.
The doubts he has do not stop him as he still goes along with his thrilling journey.
As ah enters the room he peers about. Immediately as he shuts the door behind him it's like a panic comes over him and he starts to walk up and down the room, opening the curtains and checking the locks of the windows and looking up the black chimney. He even goes as far as knocking the walls for any secret passages. He decides to light some candles in order to calm his nerves. He finally tries to relax and relies on his revolver to keep him safe.
