The Bronx is the home of Martin Dekker, a high-school physics teacher whose life is characterized by punctuality, solitude, and a habit of moving through city streets unnoticed. The borough is not presented through an extended scene of its own; instead, it enters the novel as the place Martin lives and as a destination Diane Lucas imagines during a crisis that makes even an ordinary journey uncertain.

Martin’s Home and Daily Life

Martin lives alone in the Bronx and teaches physics at a charter school for gifted students. He is described as always on time, neatly dressed, and clean-shaven, yet socially unobtrusive: he walks the streets unseen. At school, his semi-eccentric manner makes him a guide into the subject’s dense intellectual terrain. The details set his professional presence against his solitary life outside the classroom; the Bronx is associated with a man who can be attentive and purposeful while remaining almost invisible in the city around him.

A Journey Diane Imagines

After meeting Martin, Diane wonders whether he plans to return home to the Bronx. She mentally traces a possible route on foot, imagining him going north through East Harlem and then needing to cross one of the bridges. Her uncertainty is practical rather than abstract: she does not know whether pedestrians would be allowed to cross, whether the bridges would be reserved for cars and buses, or whether anything outside is operating normally. The journey never becomes a confirmed itinerary. It remains Diane’s conjecture, shaped by the loss of dependable transport and by the distance between where Martin is and the home she pictures for him.

The Borough Against a Failing City

The wider breakdown makes Diane’s imagined route consequential. In another domestic scene, Max Stenner and Diane find that their television has gone blank and their phones, landline, and computers no longer work. At a clinic, people describe stalled elevators, an abandoned subway, and empty office buildings; the lights then fail, leaving the waiting room in darkness. These failures establish the conditions that make Diane wonder how Martin might get home, but the text does not specify that each outage occurs in the Bronx. The borough’s significance lies instead in how infrastructure failure turns a familiar address into a difficult question of distance, access, and safe passage.

From Unseen Streets to Crowded Streets

Martin’s earlier association with streets where he walks unseen is later set against Max’s experience of crowded streets. Moving through the crowd, Max recalls something Martin said and wonders whether the scene before him might be an aspect of Martin Dekker’s mind repositioned in three dimensions. The novel does not identify this crowd as the Bronx, so the connection is imaginative rather than geographic. Still, it places Martin’s home borough within a larger pattern: urban space, once traversed routinely and almost invisibly, becomes difficult to interpret when ordinary systems and familiar bearings can no longer be trusted.
