here that the first of these fictional walkers around Northampton was the author himself in the concluding chapter of the previous novel, Voice Of The Fire. Moore's narratives impart information about urban geography and history which was sadly lacking in my attempt at a fictional urban walk. See here. I have suggested here how this literary technique might be applied to an sf or superhero series.
Does it make sense when some characters enter a hereafter that comprises an unfolding of their familiar urban environment into higher dimensions? It would if the hereafter were our mental projection but why should it be? People arriving in a new continent or on a new planet find the unexpected.
