The Sign from the Adult World
While the boys sleep, a military dogfight occurs high above the island. A parachutist is shot down and drifts to the mountain top, becoming entangled in the trees. This 'sign' from the world of grown-ups is ironic; rather than bringing rescue or wisdom, it brings the grim reality of war and death to the boys' doorstep. The corpse's movement in the wind creates the illusion of a living creature, setting the stage for the chapter's terror.
