Summary
Five days after his return from 1881, Vincent D’Agosta finally accepts Pendergast’s invitation to afternoon tea at the Riverside Drive mansion. The familiar setting feels alien to him now; his journey to the nineteenth century has left him with a darker worldview and lingering disorientation—he wakes at night just to breathe clean air, free of coal smoke and manure.
At the mansion, D’Agosta finds Pendergast by the fire, with Constance’s harpsichord music and stiletto awaiting her recovery. Also present are Proctor and Mime, the reclusive computer genius in a wheelchair who repaired and enhanced the time machine. Mime eagerly recounts his work, revealing the machine now requires only a single operator and possesses expanded capabilities. Pendergast acknowledges the debt owed to both men: Mime’s mind and Proctor’s hands.
D’Agosta inquires about Constance, learning she needed six units of blood and emergency surgery for a peritoneal laceration—but her strong constitution is pulling her through. Pendergast confirms she prepared carefully for Binky and Joe, leaving them the mansion and a fortune under the care of Féline, Mary, and Murphy. Leng, he notes, is dying or dead from either the mansion’s collapse or Constance’s poison.
The conversation pivots to the machine’s fate. Mime presses Pendergast to exploit its potential—curing diseases, accessing future energy technologies—while Pendergast counters that every technological advance has been weaponized against humanity. Though conflicted, Pendergast promises not to destroy the machine but refuses to authorize its use without extreme deliberation. He permits Mime to study it further, forbidding any activation—a condition Mime accepts with theatrical reluctance and a dark joke about revisiting childhood bullies that lands in frosty silence.
Key Events

- Mime recounts the repair process, highlighting the challenge of sourcing exotic components and his contempt for Proctor’s soldering skills.
- Pendergast delivers a diplomatic tribute, crediting Mime’s intellect and Proctor’s labor equally for their safe return.

Character Development
Vincent D’Agosta emerges as a man fundamentally altered by temporal displacement. The journey was not a mere adventure but a psychological rupture. His nightly ritual of breath-verification signals trauma: the nineteenth century was so sensorily oppressive that his body now mistrusts modern air. The reunion with Laura reveals reciprocal transformation—her anxiety during his absence stripped away marital complacency, leaving raw gratitude. D’Agosta has moved from skepticism about Pendergast’s world to a haunted insider’s perspective.
Aloysius Pendergast displays characteristic ambivalence about power. Having nearly lost Constance to the machine’s earlier use, he now faces Mime’s technological evangelism with weary caution. His argument—that no innovation escapes weaponization—is not abstract philosophy but hard-won wisdom. Yet he refuses destruction, suggesting unresolved temptation. His praise of Proctor and Mime shows leadership through recognition, but the chapter leaves his ultimate intentions ambiguous.
Mime receives his most substantial characterization in the series. His physical limitations contrast with transcendental intellect. The chapter reveals him as voluble, egotistical, and hungry for audience—the recluse who secretly craves connection. His bullying anecdote humanizes him, while his eagerness to exploit the machine foreshadows future conflict. The thalidomide embryopathy backstory grounds his genius in bodily vulnerability.
Proctor demonstrates quiet competence and professional dignity. His retort about acquiring components at three in the morning earns him sympathy, and D’Agosta’s observation that Proctor’s chest swelled at Pendergast’s praise confirms the chauffeur’s deep investment in approval. His silent scoff at Mime’s utopianism aligns him with Pendergast’s caution.
Constance Greene remains offstage, but her survival dominates the chapter’s emotional backdrop. The medical details—six units of packed red blood cells, peritoneal surgery—underscore the near-fatal cost of her mission. The arrangements for Binky and Joe reveal her foresight and maternal responsibility, transforming her from avenger back into protector.
Themes, Symbols, or Motifs
Clean Air as Psychological Marker – D’Agosta’s compulsion to verify the absence of coal smoke, tallow, and manure converts atmosphere into a symbol of temporal dislocation. The nineteenth century was not just dangerous but viscerally alien; modern air becomes proof of home.
The Double-Edged Gift – Pendergast’s challenge to name an un-weaponized technology crystallizes the novel’s central anxiety about the time machine. Mime’s counterargument—cold fusion, graphene, antiviral medicine—sets up an irresolvable ethical tension that drives the chapter’s drama.
Hands and Minds – The chapter draws explicit contrasts between Proctor’s physical labor and Mime’s cognitive brilliance. Pendergast’s diplomatic synthesis praises both, but Mime’s dismissal of Proctor’s soldering reveals status hierarchies even among allies. The machine itself embodies this duality: a device of pure intellect that required bloody hands to repair.
The Unresolved Promise – Constance’s stiletto atop her music, both awaiting her recovery, functions as a visual emblem of interruption. Her story is not finished, and the objects of her dual identity—artist and killer—remain in limbo, mirroring Pendergast’s suspended decision about the machine.
Why This Chapter Matters
Chapter 68 functions as both denouement for the 1881 mission and prologue for future conflict. It closes the immediate narrative loop: Constance will survive; the children are provided for; Leng is dying or dead. D’Agosta’s psychological processing validates the journey’s reality and cost. But the chapter’s primary work is to refuse closure on the time machine itself.
Pendergast’s forbearance—neither destroying nor using the device—establishes suspended stakes that will haunt subsequent installments. Mime’s promised obedience paired with his bullying-revenge joke signals unreliability. The machine, now enhanced to single-operator function with expanded range, is more dangerous than before precisely because it survived its near-destruction. The chapter transforms the device from plot mechanism into ethical MacGuffin, ensuring its shadow falls over whatever comes next.
Study Questions and Answers
1. How does D’Agosta’s psychological state in this chapter reflect the deeper costs of time travel, beyond physical danger?
D’Agosta’s compulsion to wake and verify the air’s cleanliness demonstrates sensory trauma—the nineteenth century’s olfactory assault has recalibrated his baseline for normalcy. This is not nostalgia or thrill-seeking but a destabilizing rupture that makes the familiar feel provisional. His reunion with Laura, though joyful, was awkward; the journey created an experiential gap that words cannot fully bridge. The chapter suggests that time travel’s true cost is the erosion of one’s ability to inhabit the present without vigilance.
2. What is the significance of Pendergast’s refusal to either destroy or use the machine?
Pendergast’s suspension of decision reflects a philosophical stance: the machine’s potential for good is inseparable from its potential for harm, and any choice forecloses possibilities he is not prepared to abandon. His historical argument—nuclear power produced the bomb, genetics enabled euthanasia—reveals a worldview shaped by pattern recognition of unintended consequences. Yet his promise not to destroy the machine betrays hope or curiosity, the very quality Mime seeks to exploit. The ambivalence makes Pendergast morally legible as a man wrestling with temptation rather than a saint who has transcended it.
3. How does Mime’s characterization complicate the reader’s expectations of a reclusive genius?
Mime subverts the stereotype of the silent, detached savant. He is talkative, theatrical, hungry for praise, and quick to belittle Proctor’s practical skills. His joke about traveling to 1983 to torment a childhood bully reveals pettiness beneath the intellectual grandeur, while his craving for audience contradicts his supposed reclusiveness. These contradictions humanize him, but they also make him unpredictable—someone whose brilliance does not guarantee wisdom, and whose reassurances about not activating the machine feel performative rather than sincere.
