In the story “House Taken Over” by Julio Cortazar, there is a sense of uncertainty to help create an atmosphere of fear created by not telling what or who was taking the house over. “I heard something in the library or the dining room.” (Cortazar 39) The Narrator describes what he hears but never tells what it is. The narrator sounds scared and acts nervous. This makes the reader have a nervous feeling because they are uncertain of what it is and they know it can’t be anything good. First, the narrator hears something in the other part of the house. Next, he falls to the ground, shuts the door, and locks it. The narrator then goes on like nothing happened. Once he reaches Irene’s room he explains what happened and neither sound really concerned.
