The story opens with a deathless world where a woman is dying. Anne Tabor lies on a mercury bath, and Webb Fellow, a doctor, attends to her. The clinical setting—mercury support, sedatives, blood from the whole city—immediately establishes a society where medical technology is advanced but emotions are suppressed. Webb's slip of the word "dear" triggers a chain of self-awareness, and the phrase "it's a long life" recurs as a mantra of sanity. Marks uses this repetition to underscore the tension between human feeling and the imperative of emotional control.

Clinical Diction and the Language of Detachment

The narrative voice in the excerpts is deliberately clinical. Webb Fellow is introduced with his title "Doctor," but the text notes that "almost everyone in this age had an M. D. certificate." This casual universality of medical expertise deflates the specialness of the profession. Descriptions of Anne's condition use precise terms: "mutated cancerous cell," "mutant leukemia." The mercury bath is described as a "silvery surface," blending the technical with the aesthetic. Webb's internal conflict is rendered through physical symptoms: "the web of his emotions tighten and twist into a knot of unreason." The language of medicine and machinery pervades, even in moments of intimacy.

The Recurring Catchphrase as Thematic Anchor

The phrase "it's a long life" appears multiple times, functioning as a societal slogan. Anne says it with a sigh; Webb internally calls it "That damned phrase again!" and "the cliche of cliches." Marks uses this repetition to show how a culture of immortality has reduced complex emotional wisdom to a reflexive dismissal. The phrase is invoked to explain away attachment, jealousy, and violence. When Webb later reflects on his actions, he thinks "It would still be a long life for Anne," revealing how the mantra has been internalized even in crisis. The story thus critiques the very logic it presents.

Dialogue as a Battle of Subtext and Control

Dialogue in the excerpts is often indirect, with characters speaking around their feelings. Webb's "I'm glad you came to me, Anne" is met with her explanation that she chose him over Cliff because "Cliff hasn't practiced for a century or more." The reason is practical, not emotional. When Webb repeats "dear," Anne's response is a question: "Did I hear correctly?" The exchange is a dance of acknowledgment and denial. Later, the confrontation between Webb and the roboid Clifford reveals a dialogue where one party is performing a scripted role. Clifford's calm explanation—"To discharge the murder impulse"—uses the language of computation and therapy, not accusation.

The Robot Double and the Logic of Prediction

The twist that the murdered Clifford is a robot—"Ainsley the Second. Strictly a lab job"—introduces a layer of metafictional play. Clifford reveals he anticipated Webb's actions using a "probability computation" based on Webb's genetic pattern and stress factors. This turns the murder into a controlled experiment. The robot's purpose is to "discharge the murder impulse" so that the real Clifford remains safe. The story thus uses a science-fictional device to literalize the theme of emotional management. The final line, "there is no total key," suggests that life—and narrative—resists final resolution.

The story's brevity (under 7,000 words) and its reliance on a single setting—the medical suite—create a tight focus on psychological and philosophical conflict. Readers may note how Marks balances the clinical with the colloquial, and how the robot twist reframes the earlier dialogue as a kind of scripted performance. The absence of a definitive ending aligns with the story's skepticism about closure in an immortal world.
