"We may dream, perhaps, that it might be possible to have another and higher romance of London, that men's souls have stranger adventures than their bodies, and that it would be harder and more exciting to hunt their virtues than to hunt their crimes. But since our great authors (with the admirable exception of Stevenson) decline to write of that thrilling mood and moment when the eyes of the great city, like the eyes of a cat, begin to flame in the dark, we must give fair credit to the popular literature which, amid a babble of pedantry and preciosity, declines to regard the present as prosaic or the common as commonplace."
