Isolation and Community

The remote island of Ransay is both a refuge and a trap—its small, close-knit community is initially suspicious of outsiders, yet the protagonist must rely on local allies (like Jean) to survive, showing how isolation fosters both secrecy and solidarity.

The narrator experiences profound loneliness after Rutherford's departure, drifting alone in the fog.

The narrator's solitary landing on a desolate island and his encounter with a single, suspicious individual emphasize the isolation and the fragile beginnings of community.

Alone on the island, the protagonist finds temporary refuge and community at a farm, contrasting his solitary mission with the warmth of human hospitality.

The island of Ransay is depicted as a small, isolated community with only a few 'civilised' houses, where everyone is known and a stranger stands out.
