Act of Oblivion

A Manhunt Across an Ocean

Robert Harris has built one of the most reliable careers in historical fiction by finding the propulsive thriller buried inside the historical record. From the alternate-history menace of Fatherland to the papal intrigue of Conclave and the Dreyfus affair of An Officer and a Spy, he has a gift for transforming meticulously researched history into page-turning suspense. Act of Oblivion continues that tradition, mining a fascinating and little-known true story: the transatlantic manhunt for the men who signed the death warrant of King Charles I.

The novel opens in 1660, in the aftermath of the English Civil War and the collapse of Cromwell’s Commonwealth. With the monarchy restored under Charles II, the new king turns his attention to vengeance. The “Act of Oblivion” of the title was a real piece of legislation granting amnesty for crimes committed during the war — with one crucial exception. The regicides, the men responsible for executing the king’s father, were explicitly excluded from pardon, marked for death and hunted without mercy. Two of them, the real historical figures Colonel Edward Whalley and his son-in-law Colonel William Goffe, flee across the Atlantic to the Puritan colonies of New England, hoping to disappear into the wilderness.

Hunter and Hunted

Harris structures the novel as a relentless cat-and-mouse chase. Pursuing the fugitives is Richard Naylor, a clerk of the Privy Council and Harris’s chief fictional invention — a coldly obsessive manhunter who makes the capture of the regicides his personal mission. As the two colonels move from one precarious hiding place to another, sheltered by sympathetic Puritans but never safe, Naylor follows their trail with implacable determination, crossing the ocean himself to run them to ground.

This pursuer-and-prey structure gives the novel its momentum. Naylor is a genuinely compelling antagonist, his obsession given a personal dimension that Harris reveals gradually, deepening the reader’s understanding of why he hunts with such ferocity. The fugitives, meanwhile, are sympathetic without being sentimentalized — men of fierce religious conviction who believed they were doing God’s work in executing a tyrant, now reduced to hunted animals living in caves and cellars, paying a terrible price for their part in history.

Two Worlds in Contrast

One of the novel’s great pleasures is its vivid evocation of two utterly different worlds. In England, Harris conjures the paranoid, vengeful atmosphere of the Restoration court, where old loyalties are deadly and the settling of scores is brutal. In New England, he renders the harsh, unforgiving reality of the early Puritan colonies — the brutal winters, the precarious settlements, the rigid theocratic communities, the ever-present danger of the wilderness and of conflict with Indigenous peoples. The contrast between the sophisticated cruelty of the Old World and the grim hardship of the New gives the book its rich texture.

Harris’s research, as always, is impeccable, and he wears it lightly, weaving historical detail into the narrative without bogging it down. The reader emerges with a vivid sense of a turbulent period and a genuine understanding of the stakes for everyone involved.

Pacing and Patience

If the novel has a weakness, it lies in its middle stretch. The sections depicting the colonels’ long years of hiding in the New England wilderness — the privation, the boredom, the slow erosion of hope — are atmospheric and emotionally affecting, but they also slow the momentum that the manhunt structure establishes so effectively. The fugitives’ enforced stillness is the point, dramatically, but it means the chase occasionally stalls, and readers craving relentless thriller pacing may find these passages a test of patience. The large cast of historical figures can also be challenging to track in the early chapters.

These are minor reservations. Act of Oblivion is, on balance, a thoroughly satisfying historical thriller, and its quieter passages serve a real purpose, dramatizing the psychological toll of a life spent in hiding and fear.

Faith, Conviction, and Doubt

Beneath the chase, Harris is deeply interested in belief. Whalley and Goffe were not opportunists but devout men who signed the king’s death warrant in the conviction that they were instruments of divine justice. Years later, hunted and broken, they are forced to wrestle with whether that conviction still holds — whether God truly sanctioned what they did, or whether they have damned themselves and their families for a cause that has crumbled to dust. Harris treats this spiritual crisis with seriousness and sympathy, refusing to caricature the Puritan worldview that drove these men. The novel becomes, in part, a study of how zealous certainty curdles into doubt under the pressure of suffering and exile. That interior dimension lifts Act of Oblivion above mere adventure, lending the manhunt a moral and psychological weight that lingers after the chase concludes. It is a reminder that the most enduring historical fiction illuminates not just events but the inner lives of those who lived through them.

A Story Worth Telling

What elevates Act of Oblivion is its thematic resonance. It is a meditation on the long reach of political vengeance, the obsessive nature of pursuit, and the way history’s defeated are hunted long after the war itself is over. Harris finds genuine pathos in the plight of men who acted on conviction and lived to see their cause collapse, and genuine menace in the figure who will not rest until they are dead. The moral complexity — these regicides were both principled idealists and king-killers — gives the novel a depth beyond its thriller mechanics.

For Harris’s many admirers, Act of Oblivion is a worthy addition to his body of work, delivering the intelligent, immersive, well-researched historical storytelling that is his trademark. For readers new to him, it is an excellent introduction to a writer who understands, better than almost anyone, how to make the past feel urgent and alive.

Our rating: 4.1/5 — A gripping, meticulously researched transatlantic manhunt that turns a real seventeenth-century pursuit into vintage Robert Harris suspense.
