After the frigate Alliance runs aground, its officers take the lifeboats and cut the towlines, abandoning more than a hundred crew on a makeshift raft. Over days adrift, the survivors kill the wounded and weak to stretch rations and resort to cannibalism.
On the raft, cruelty arrives through calculation rather than frenzy. Once food and space are fixed and the rescuers have gone, each killing is reasoned out as the arithmetic of who can still be kept alive. The horror is that the men stay rational, so the mind that made civilization possible also organizes the slaughter.
The guests treat the sea as something to be located and measured. The painter Plasson paints the sea with seawater, searching for the point where it begins. Professor Bartleboom records where each wave stops for his Encyclopedia of the Limits. The sea keeps defeating their instruments, so each quest exposes the seeker's need for edges more than it reveals anything about the water.
The inn half treats the sea as a remedy. The frail Elisewin and the adulteress Ann Devereia are sent to the shore to be healed or corrected by exposure to it. The raft half, titled 'the belly of the sea,' shows the same water devouring people and stripping them to appetite. Setting the halves side by side shows that the romantic, therapeutic view of nature is only possible from dry land.
