In my opinion, I feel very strongly that the short story, The Landlady is a horror story. Think about it, In the beginning, it is a dark and rainy day. That is how almost all scary stories are told. The author, Roald Dahl, used a lot of words like deadly or words that mean death in the beginning.
When Billy sees the Bed and Breakfast, he goes straight to it, it sticks out from all the other houses, with paint fading. The flowers next to the window are common in funerals. Billy peeks inside and sees a dog lying down next to the glowing fireplace. Then, he goes inside and meets the landlady, who allows him to rent a room. The landlady acts really kind, she offers to make the price of his room cheaper, plus, the Bed and Breakfast have very cheap rooms. Billy then realizes that the dog is stuffed. In fact, all the animals in the room are stuffed after dying.
After Billy goes into his room, he is asked to sign his name in a notebook in a drawer. Billy then sees that the last entries were from years ago. There were two entries, and that the news said that there were two missing people. The Landlady then tells him that the two people are still in their rooms. They were stuffed, just like the other animals. Later, when they are having tea, the Landlady keeps on shutting him down when he asks about it. Billy thinks that the tea he has tasted like bitter almonds, which actually contain a type of poison.
In the end, Billy probably died from the tea of just like the other two people, got stuffed. The message is deception, then Landlady, who acts very nice at the beginning is the one who kills Billy. These are my reasons why I think that the Landlady book is a horror story.
