Night Watch — Discworld #29 — City Watch

Pratchett’s Masterwork

By 2002, Terry Pratchett had written twenty-eight Discworld novels. In Night Watch — the twenty-ninth — he wrote the one that almost everyone agrees is the best. It is a time-travel story, a political novel, a meditation on mentorship and loss, and the fullest expression of everything he had been building across thirty years of fiction. It is also, at regular intervals, very funny. But the jokes here carry weight in a way that even the finest earlier Discworld novels do not fully anticipate.

The premise is deceptively clean: Sam Vimes, now Commander of the City Watch and one of Ankh-Morpork’s most powerful figures, is thrown back in time during a confrontation with a serial killer. He lands in the Ankh-Morpork of thirty years earlier, on the eve of the Glorious Revolution — the uprising that shaped the city and the political generation that runs it in Vimes’s own time. Worse, he has landed in the place of his own mentor, John Keel, who dies in the translation. To get back to his own time — and to his pregnant wife — Vimes must become Keel, and train his own younger self.

The Ethics of Revolution

What Pratchett does with this premise is astonishing. The Glorious Revolution is neither glorified nor cynically dismissed. It is shown as a genuine expression of human desire for dignity — and also as something that will be betrayed, suppressed, and rewritten before the last barricade comes down. Vimes knows how this story ends. He has to live through it anyway.

The novel’s political intelligence is formidable. Pratchett has thought deeply about what revolutions are for, what they cost, and why the ideals they represent tend to outlast their practical outcomes. The “Treacle Mine Road” uprising is not merely background — it is the novel’s subject, examined with the same rigour Pratchett brought to religion in Small Gods and to justice in Guards! Guards!.

A Mentor’s Impossible Task

The emotional core of Night Watch is the relationship between Vimes and his younger self — a young watchman not yet hardened into cynicism, still capable of the naive belief in the Watch as an institution of justice that Vimes the Commander has had to fight his whole career to preserve. Watching Vimes teach his younger self the things that made him who he is — knowing the price those lessons came with — is handled with a delicacy that the label “comic fantasy” does not remotely prepare the reader for.

The scene at the barricade that gives the novel its most famous image — the lilac, worn in remembrance of those who died for something briefly real — has become one of the touchstones of Pratchett’s work, cited by readers as the moment they understood the full scale of what he was doing.

Why Read the Preceding Books First

Night Watch can be read in isolation — it provides enough context to be comprehensible. But it cannot be fully felt without knowing who Vimes is: the arc from the drunk captain of Guards! Guards! to the Commander of this novel is one of fantasy fiction’s great character trajectories. Readers new to the Discworld should begin with Guards! Guards!, work through the City Watch sub-series, and arrive at Night Watch having earned it.

Our rating: 4.6/5 — Pratchett’s masterwork: a time-travel political novel that uses the Discworld’s comic architecture to explore revolution, mentorship, and the nature of justice with a moral seriousness and emotional power that few novels of any genre can match.

Pratchett at His Best

Terry Pratchett published Night Watch in 2002, twenty-eight novels into the Discworld series. It was the year he turned fifty-four. He had spent nearly two decades building Sam Vimes from a drunk with a conscience into one of fiction’s most fully realised moral figures, and he knew it. Night Watch is the novel of a writer who knows exactly what he has been building and has decided to do the most ambitious possible thing with it.

The result is the novel that, in reader polls taken consistently across the two decades since its publication, is chosen as Pratchett’s best. Not the funniest (that is probably Wyrd Sisters or Going Postal), not the most philosophically rich (that is probably Small Gods), but the one that brings together everything Pratchett could do — comedy, character, political intelligence, emotional depth, genuine historical engagement — into a single unified achievement.

The Glorious Revolution of Treacle Mine Road is not based on a single historical event but on a composite of the urban uprisings that marked European cities throughout the nineteenth century: the barricades of Paris, the insurrections of Vienna and Berlin in 1848, the specific texture of a moment when ordinary people decide that the situation is unacceptable and act on that decision. Pratchett takes this seriously. He does not romanticise it — Vimes knows how it ends, which means the reader knows — but he does not dismiss it either. The people who die at the barricades die for something real, even if what they died for does not survive in the form they imagined.

The lilac worn on the anniversary is Pratchett’s most lasting image: a reminder that some events are too important to be processed into history, that some losses demand continued acknowledgment. The detail that the Discworld’s Ankh-Morpork has a population that still, decades later, wears lilac on that day — has organised its collective memory around the recognition of what happened — is one of the finest things in the entire series.

Pratchett was knighted in 2009 and died in March 2015. Night Watch appeared thirteen years before his death, at a point when he was at the height of his powers and producing his most important work. Readers who come to it last, after working through the preceding Watch novels, will find it changed their understanding of everything that came before.
