The theme of the book is simple: a man is dying: you feel him sinking throughout the book; his thought and his memories pervade the whole with greater or lesser distinction (like the swell and fall of uneven breathing), now rolling up this image, now that, letting it ride in the wind, or even tossing it out on the shore, where it seems to move and live for a minute on its own and presently is drawn back again by grey seas where it sinks or is strangely transfigured.
