Picture this:  I'm in the house all alone.  The washing machine & dishwasher have finished their cycles, the TV and CD player are off; it's quiet. There's not a breath of wind outside and none of the windows are open. The doors are locked. I'm peacefully catching up on Board action and...
the loft hatch crashes open and hangs there, swinging on its hinges. Aaaaaargh.
Do I go up the ladder and stick my head through the hatch - or will it be chopped off by some maniac zombie whos been hiding up there waiting for the perfect moment to get me by myself and behead and disembowel me?
Or maybe I've just been thinking about Sean of the Dead in my sleep!
