Curtain

Curtain Review

In 1940, with German bombs falling on London and no certainty that she or her life’s work would survive the war, Agatha Christie wrote what she intended to be Poirot’s final case and locked the manuscript away. She would not allow it to be published until after her death. She wanted to say goodbye to her detective on her own terms, in her own time, without external pressure.

Curtain was published in September 1975, six months before Christie died. It is everything a farewell should be and almost nothing a commercial finale would dare to attempt.

Arthur Hastings returns to Styles Court — the country house in Essex where, decades earlier, his friend Hercule Poirot solved his very first English murder case. Styles is now a guest house, somewhat faded. Poirot is there already, old and wheelchair-bound, his heart condition severe. He has asked Hastings to come. Among the guests, he has identified someone he calls X — a murderer of unusual cunning, a person who has never been convicted because they arrange for others to commit the crimes they engineer. Poirot intends to stop X.

The concept Christie deploys — the indirect murderer who operates through suggestion and psychological manipulation — is one of the most intellectually original ideas she ever brought to the series. It places the central problem at the intersection of law, morality, and evidence in a way that conventional detection cannot resolve, and forces Poirot to act outside every constraint he has honoured for his entire career.

What gives Curtain its particular weight is the return to Styles. Christie understood that the resonance of an ending depends on the resonance of a beginning. The circle closes, and it closes perfectly.

Written During the Blitz

The circumstances of Curtain’s composition are essential to its meaning. Christie wrote it in the early years of the Second World War, when German bombs were falling on London and there was genuine uncertainty about whether any of them — Christie, her manuscripts, her life’s work — would survive. She wrote Poirot’s farewell as an act of insurance: if she died, the final chapter of her detective’s story would exist. She deposited the manuscript with her publisher with instructions that it should be published after her death.

That it was published instead in 1975, while Christie was still alive but in severe decline — she would die in January 1976, four months after the book’s appearance — gave the novel a different kind of valedictory weight than she had originally intended. She was alive to see the world respond to Poirot’s death. The New York Times ran an obituary for Hercule Poirot on its front page in August 1975, the only time a fictional character had been accorded this distinction. It is a measure of how completely Christie had made her creation real.

The Return to Styles

The decision to set Poirot’s final case at Styles Court — the country house where he had solved his first English case more than fifty years before — was not merely a sentimental gesture. Christie understood that the best endings return to the beginning not for nostalgia but because the circle reveals what the journey has meant. The Styles of Curtain is shabby, reduced, somewhat worn; the world that produced the bright social scene of The Mysterious Affair at Styles has passed through two world wars and come out different. Poirot and Hastings have aged with it.

Hastings’ narration in Curtain achieves something it rarely managed in the earlier Poirot novels: genuine emotional depth. He is older, widowed, and arriving at Styles with his daughter in tow — a daughter who, in an irony Christie clearly intended, reminds Poirot of Hastings’ younger self. The symmetry is not labored; it simply exists, as good structural choices in long fiction tend to exist, as an inevitability that could only be seen from a sufficient distance.

The Moral Architecture of the Solution

The concept Christie deploys — a murderer who operates by suggestion, by subtle psychological manipulation, by creating the conditions in which others commit the crimes the puppet-master has designed — is genuinely original in the detective fiction genre. It places the central problem where no conventional investigation can reach, because the person most responsible for the deaths has technically committed no crime. The law cannot touch X. The evidence is immaterial. Poirot’s methods — physical evidence, testimony, logical deduction — are useless here.

This impossibility is what drives Poirot to the action that defines the novel’s final act and that separates Curtain from any other entry in the series. Christie does not flinch from the implications. Poirot acts, and the act costs him exactly what it should cost him, and the novel ends in the only honest way it could.

The decision to have Hastings understand only retrospectively what his friend did — and why — is perfectly calibrated to the series’ fundamental relationship. Hastings has always understood Poirot less fully than he believed. In the end, what he misses is not stupidity but an unwillingness to believe his friend capable of what his friend was capable of. That failure of imagination is its own kind of tribute.

Our rating: 4.5/5 — A genuinely remarkable finale, written under wartime conditions and published posthumously, in which Christie gives Poirot a farewell of extraordinary emotional honesty and intellectual originality.
