There is a kind of deliberate, even Aristotelian unity to this novel. Thus, the novel starts at daybreak, and the successive chapters are located at different times of the evolving day—noon, twilight, midnight—and ends at the end of the 24-hour cycle, dawn again. It is another matter that this diurnal cycle is actually spread over many years and several generations. But despite this appearance of formal ordering, the novel itself seems to use its very formlessness, its sense of fated drifting, as part of its narrative argument.
