"My friend is dead, my neighbour is dead, my love, the darling of my soul, is dead; it is the inexorable consolidation and perpetuation of the secret that was always in that individuality, and which I shall carry in mine to my life's end. In any of the burial-places of this city through which I pass, is there a sleeper more inscrutable than its busy inhabitants are, in their innermost personality, to me, or than I am to them?"

--from "A Tale of Two Cities" (1859) By Charles Dickens
