Irene and her brother live in an old spacious house all by themselves. They come from an upper class family which means that they stay in the house all the time without going to work.
House Taken Over
Each of the sibling have hobbies to do. The narrator likes reading books and his sister is good at knitting. They usually finish cleaning and doing other chores and then practice their hobbies.
One time, while he was preparing some matè to drink, the narrator heard voices behind the door that connects them to the other part of the house. He quickly shut the door and continued preparing his tea.
He told Irene about what happened but she didn't seem very shocked or gave a reaction at all. Though she always keep hallucinating in her sleep and he keeps moving and throwing things at night. This shows that they are scared of what's happening since their true emotions come out at night.
The narrator and his sister started hearing the voices clearer. The noise was coming from the kitchen. At that point they realized that "they" are taking over the house.
Irene and her brother quickly left the house without having time to take anything with them. They took the key and got rid of it so no one can enter it again. They didn't have any other place to go to.
