The City

What happens

The household travels to the city for Josie’s ‘portrait’. They are met by Paul, Josie’s father, an engineer who has been ‘substituted’ out of his job and now lives in a community of similarly displaced people. At Mr Capaldi’s studio, Klara discovers the truth: the ‘portrait’ is an AF body, an exact Josie, waiting to be inhabited. If Josie dies, Klara is to ‘continue’ her, not imitate her, Capaldi insists, but become her, because in his view there is nothing inside Josie beyond the reach of science. The Mother, wrung out by grief and fear, begs Klara to agree. Paul takes Josie away in fury.

That evening Klara and Paul find the Cootings Machine in a scrapyard and destroy it, using fluid drawn from Klara’s own body, a sacrifice that she knows may impair her. Meanwhile Helen humbles herself before her old lover Vance to beg a college place for Rick, and is coldly savoured and refused; and a woman in a theatre queue turns on Klara with open hatred: ‘First they take the jobs. Then they take the seats at the theatre?’ On the drive home, Klara sees a new Cootings Machine, her sacrifice, it seems, was for nothing.

A closer look

Capaldi versus the human heart

Part 4 stages the novel’s central argument as a debate between two men. Capaldi is the pure materialist: a person is information, patterns, retrievable data, ‘nothing inside Josie that’s beyond the Klaras of this world to continue.’ Paul reaches instead for ‘the human heart… in the poetic sense’, something ‘unreachable’ inside each of us, and then makes the most honest admission in the novel: ‘I think I hate Capaldi because deep down I suspect he may be right.’ Ishiguro refuses to settle the question here; he saves the answer (and it is an answer, of a kind) for Klara in Part 6. In an essay, treat Capaldi less as a villain than as a position, the novel needs him the way a debate needs an opponent.

The scrapyard sacrifice

Klara giving up her own fluid to poison the Cootings Machine is science written as scripture: an offering, made in secret, at real personal cost, on behalf of another. It is also (and this is the Ishiguro touch) very possibly pointless, since the machine is simply replaced. The gesture matters more than its efficacy. Compare the Mother, who will sacrifice anything except her own hope, and Capaldi, for whom sacrifice is an irrational rounding error. Whose version of love survives the novel best?

A society fraying at the edges

Around the central drama, Part 4 quietly widens the lens: Paul’s community of ‘substituted’ professionals, the theatre-goer’s anti-AF fury, Vance’s gatekeeping of the one route left for unlifted children. This is your AO4 goldmine, automation and displaced workers, resentment of new technology, elites pulling up the ladder, but weave it in; never bolt it on. One integrated sentence (‘Paul’s “substitution” echoes contemporary fears of AI taking white-collar work…’) outscores a paragraph of recited facts.

Key quotations

Quotation	Method	Why it matters
‘We’re asking you to become her.’	Shock revelation	The novel’s premise detonates: companionship was always, potentially, replacement.
‘Something unreachable inside each of us… But there’s nothing like that.’	Antithesis (Paul vs Capaldi)	The soul, asserted and denied in a single exchange, the question the whole novel turns on.
‘I think I hate Capaldi because deep down I suspect he may be right.’	Confession, modality	Doubt as characterisation: even the novel’s humanist can’t be sure.
‘Hope. Damn thing never leaves you alone.’	Personification, colloquial register	The Mother’s hope as affliction, a bitter counterpoint to Klara’s sustaining faith.
‘First they take the jobs. Then they take the seats at the theatre?’	Rhetorical escalation	Public resentment of AFs, the social backlash that will leave Klara in the Yard.
‘Perhaps all humans are lonely. At least potentially.’	Aphorism, qualified claim	Klara’s conclusion from the city, tentative, precise, and truer than anything the adults say.
