In a forest somewhere outside the city, the protagonist meets a woman and they have sex. After, he tells her that he has "lost something"—he cannot remember his name. She leads him to a cave and tells him to enter. Inside, he finds long loops of chain fitted with miniature prisms, mirrors, and lenses. He dons the chain and leaves the cave, only to find the woman in the middle of a field, turning into a tree. Panicked, he flees. Many characters in the novel wear the same sort of “optic chain”; all are loath to discuss how they came to do so. On a nearby road, a passing truck stops to pick him up. The trucker, hauling artichokes, drops him off at the end of a suspension bridge leading across the river to Bellona.
