And I tell you straight out: suspicious this makes me, for what is the cause to bring magic back when it has been replaced by something clearly more serviceable? So the first riddle I put my mind to was this: in a world where carriages travel without beasts to pull them, and food is effortlessly abundant, and there is ample light to sunder any darkness, from all manner of peculiar torches, none of them given to burning down a place even if it is all wood, and where all and sundry wear grander clothes than most anyone in London and an astonishing variety what's more . . . something there must be, some commodity or advantage, that magic can attain but mankind cannot yet. Nothing material can it be, for no magic I ever knew summoned such luxuries for royalty as everyday folk here take as commonplace.
