Leo tried to delete the file, but the icon stayed glued to the home screen. He pulled the battery, but the screen stayed lit. The bone-white interface began to bleed into the edges of his physical world. The purple LED on his keyboard turned white. The light in his hallway flickered in code.

Leo installed it on a burner phone.
