I must have been sitting on a chair on the balcony for hours. The evening shadows were drawing on apace, so I hurried back into the living room, feeling it was weird to be there all alone with every one of the other 98 apartments in The Denizen unoccupied. I knew these were ghost homes that the owners had bought as investments and not to live in, but even so it seemed odd that besides me there was only the concierge in the building. The sun had sunk below the horizon by this time. With my own eyes I saw that one of the doors I had shut was standing wide open! I turned to the other two bedroom doors. They were closed as I had left them. It was the master bedroom door that had moved. For a second I stood appalled and frightened.
