I'm sure all of you can imagine my very great disappointment when I discovered, after having left King's Cross station last August (in the midst of a fire alarm in the Tube station below) that there is indeed a platform nine and three quarters at King's Cross, with directions for us tourists to find it. Clearly, that fire alarm was a conspiracy. I really don't feel, having been pushed out into London, that I was saved from a greater evil.
Of course, there were many signs concerning Middle earth about Oxford.
