Who in the UK felt that earth tremor just now? (About 1am it happened). Quite a big one that! I was upstairs as well so I felt it pretty well. I remember we had one about 6 years ago, but I was in bed... at 6pm ! That was no doubt the first one I've really experienced.
The man who comes back through the Door in the Wall will never be quite the same as the man who went out.
