In The Hole by Øyvind Torseter, a man is moving into a new home, and he notices a hole in the apartment. The hole seems to move around, appearing in a wall, on the floor, in a door, etc.
The man makes a phone call, saying, “I’ve found a hole . . . in my apartment . . . it keeps moving . . . take it with me . . . to you?” Attempting to capture the hole in a box, he heads out the door with the box and takes it to a lab for tests.
The book has a die-cut hole that runs through the entire book, and in every page the hole is part of the story.
Are holes part of the world? Are they physical objects? What are they made of? If they’re made of nothing, how do we perceive them? What makes something a hole? Does it have a shape? Do holes really exist? If you fill a hole, is it no longer a hole?
