I've never actually read Mayhew, but feel I've long had him, through
brilliant osmosis, with Kellow Chesney's Victorian Underworld, which is easily one of my favorite books
ever. People assume, when I tell them that, that Chesney would mainly
have influenced The Difference Engine, but actually this was very
consciously the basis of the criminal society of Neuromancer, et al. It
was a Victorian model, as I saw what's since come to be called
neoconservatism producing a neo-Victorian world. Not a bad call, either!
I literally had The Victorian Underworld on my desk constantly,
throughout the writing of Neuromancer, and for years after.
