Not long after the meeting, some military planes engage in a battle high above the island. The boys, asleep below, do not notice the flashing lights and explosions in the clouds. A parachutist drifts to earth on the signal-fire mountain, dead.
The boys organize a hunting expedition to search for the monster. Jack and Ralph, who are increasingly at odds, travel up the mountain. They see the silhouette of the parachute from a distance and think that it looks like a huge, deformed ape.
Jack declares himself the leader of the new tribe of hunters and organizes a hunt and a violent, ritual slaughter of a sow to solemnize the occasion. The hunters then decapitate the sow and place its head on a sharpened stake in the jungle as an offering to the beast.
Later, encountering the bloody, fly-covered head, Simon has a terrible vision, during which it seems to him that the head is speaking. The voice, which he imagines as belonging to the Lord of the Flies, says that Simon will never escape him, for he exists within all men. Simon faints.
You will never escape me.
When he wakes up, he goes to the mountain, where he sees the dead parachutist. Understanding then that the beast does not exist externally but rather within each individual boy, Simon travels to the beach to tell the others what he has seen. But the others are in the midst of a chaotic revelry—even Ralph and Piggy have joined Jack’s feast—and when they see Simon’s shadowy figure emerge from the jungle, they fall upon him and kill him with their bare hands and teeth.
The following morning, Ralph and Piggy discuss what they have done. Jack’s hunters attack them and their few followers and steal Piggy’s glasses in the process.
