Ha, I never heard his name as place. (I'm really bad with names that way; I don't hear them as regular words, just sounds of a person's name). But now, as I imagine it, Jack London does not feel like what he writes at all. My immediate image was a London street at night, shiny with rain and a man with a top hat and cane and less than noble intentions. I think there's a melding of London and Jack the Ripper in that.
