Something not quite right

I get out of the lift in our apartment building and as I’m walking along the long, rubbery corridor towards our flat, something catches my eye. Through the window at the end, I see the lights of another house. Buildings do tend to sprout up like mushrooms around here, but I’m sure that wasn’t there before. Maybe it’s because I’m coming home at an unusual time and the people who live in that house are not normally home, so I’ve never noticed the lights before. No, that can’t be right. There was never a building that close to ours. They’ve built a bloody house overnight! But how come I didn’t hear any noise? And how come someone’s already moved in?

The weirdness is just beginning – I’m so busy staring suspiciously at the new house that I don’t notice the light outside our flat. WTF? Did I leave that on? I never even use that light! Something terrible’s happened. The police are in our flat because Beast has been found dead or some such. As I reach out to the door handle, something stops me. A red umbrella propped against the wall. And a strange sticker on the door. I blink uncomprehendingly for a moment before I see it. Flat 201. Wrong floor. I trudge off down the rubbery corridor again, shaking my head.
