The river of life, of mysterious laws and mysterious choice, flows past a deserted embankment; and along that other deserted embankment Charles now begins to pace, a man behind the invisible gun carriage on which rests his own corpse. He walks towards an imminent, self-given death? I think not; for he has at which to build; has already begun, though he would still bitterly deny it, thought there are tears in his eyes to support his denial, to realize that life, however advantageously Sarah may in some ways seem to fit the role of Sphinx, is not a symbol, is not one riddle and one failure to guess it, is not to inhabit one face alone or to be given up after one losing throw of the dice; but is to be, however inadequately, emptily, hopelessly into the city's iron heart, endured. And out again, upon the unplumb'd, salt, estranging sea.
~ John Fowles
