Then in the evening I took a Jack the Ripper walking tour, which was really interesting; the guide was Donald Rumbelow, who's apparently the leading international authority on the Ripper. He made it seem like a story; it was like walking through a movie set. At one point, we were standing in front of a parking garage and Donald was describing the apartment building that used to be there, where Mary Kelly (the last victim) was murdered. Suddenly, a young man climbed over the second-story garage railing, shinnied down to the ground, and ran down the alley. It was eerie, like seeing a reenactment of what it must have been like to a passerby, even though the building was different.
Anyway, now I'm sitting in an internet cafe in Oxford Street. I shopped and hit Starbucks (the slowest Starbucks in the entire world!), and I'm about to go to the London Dungeon, of which I know very little except that it's supposed to be (a) entertaining, and (b) creepy. We'll see.
