Nothing has immediately changed since the last time you were here. The door opens out into another big, empty space, half the width of the block. Your torch picks out a single door in the partitioning wall, the other side of which is a mirror image of where you are now. You walk around a stack of stored furniture, and then go through the double doors to where the toilets and the entrance to the lift is.
Opposite is the corridor that leads to Metcalf’s office. You go down it, and try the door. It’s still locked, and there’s no light leaking from under the door. You lost your keys when you fell, so you can’t try them again. If you want in, you’re going to have to break down the door somehow.
