The story opens with a blunt confession: "Murdering Stein was easy." This direct, almost clinical statement sets the tone for a narrative that balances hard science with psychological tension. The setting—a wrecked ship on a low-gravity asteroid—immediately establishes physical constraints that shape every action. Characters weigh only five or six pounds, and the extreme curvature hides Jonner's legs from view. Fontenay uses these details not as decoration but as functional elements of the plot, influencing how characters move, communicate, and plan.

The narrative voice shifts between Kraag's interior monologue and dialogue-heavy scenes. Kraag's thoughts are calculating and defensive, while Jonner's speech is measured and deliberate. This contrast creates a rhythm of action and reflection, with the pace slowing during Kraag's strategic analyses and quickening during exchanges of threats.

A Duel of Unequal Resources

The conflict is framed as an asymmetric struggle: Kraag holds the ship, the guns, and the food supply, while Jonner is outside, weaponless, with limited provisions. Yet Kraag feels increasingly on the defensive. Fontenay builds tension by cataloging each advantage and its erosion. Kraag has "the guns, he had the sphere," but Jonner systematically strips away his comforts—removing the solar mirror, battering the hull, forcing Kraag to live in a spacesuit.

The dialogue reveals a power dynamic that contradicts the material imbalance. When Kraag threatens Jonner with a gun, Jonner laughs and warns him away from his old .45, claiming it "is a lot more likely to turn on my enemies." This exchange, laced with dark humor, shows Jonner's psychological upper hand. Kraag's internal question—"How had it happened? How could it happen?"—underscores his bewilderment at being outmaneuvered despite superior firepower.

Scientific Precision as Narrative Device

Fontenay weaves technical details into the story without halting the action. The escape velocity of the asteroid is given as 1,552.41 feet per second, and the diameter as 0.06 (presumably Earth diameters). These figures are not exposition; they are debated by the characters, revealing their expertise and the uncertainty of their situation. Stein's calculations suggest they are on Ceres, but Jonner notes discrepancies with the latest tables.

The low gravity is a constant physical presence. Characters slip rather than walk, and a boulder that would weigh a ton on Earth can be moved by hand. This environment shapes the duel: Kraag cannot simply shoot Jonner from a distance because the curved horizon hides him, and Jonner's sledgehammer blows shake the sphere. The science is not window dressing but a constraint that drives the plot.

Pacing Through Alternating Perspectives

The narrative oscillates between Kraag's tense interiority and external scenes of Jonner's methodical work. Kraag's sections are filled with strategic calculations and paranoia: he paces, smokes, and reviews his options. Jonner's actions are described with spare, physical detail—digging, burying Stein, writing on a monument. This alternation creates a rhythm of stillness and motion.

Fontenay uses time markers to control pace. Kraag's watch tells him when it is morning; he sleeps fitfully, waking every 30 or 40 minutes to a blow on the hull. The ultimatum—"You have today to surrender. Tonight I'm going to hatch you out"—gives the narrative a deadline. The slow burn of Kraag's waiting contrasts with the impending violence, making the story feel both deliberate and urgent.

Readers should attend to how Fontenay uses the asteroid's physical laws to shape the conflict. The low gravity, limited resources, and curved horizon are not merely atmospheric; they are active elements that determine what characters can and cannot do. Pay attention to the way Kraag's internal monologue reveals his growing unease, and how Jonner's actions—each small and deliberate—accumulate to shift the balance of power. The story rewards close reading of its technical details and the subtle psychology of its duel.
