Nicholas Wennö: Slow Horses Is the Quickest Spy Series Ever

Nicholas Wennö: Slow Horses Is the Quickest Spy Series Ever

Introduction: A critic’s answer to a genre relaunch

In a recent conversation, Swedish critic Nicholas Wennö asked why Mick Herron—and a cadre of British writers—are so deft at sketching bureaucratic and political intrigue. Herron’s reply was blunt and revealing: political chess runs in their blood, just as cricket, shame, and boozy nights do. That sly self-awareness frames Slow Horses not as a conventional espionage story, but as a sharp, burlesque reimagining of the spy novel.

Herron, now celebrated as one of his generation’s premier spy writers, has long been seen as John Le Carré’s conceptual heir. His books have sold in the millions, with the signed first edition of Slow Horses (2010) fetching high prices on the collectors’ market. The premise—MI5’s least glamorous operatives consigned to Slough House—turns the idea of the hero on its head and invites readers to root for the misfits, the “loosers, misfits and boozers” who stubbornly keep working against the odds.

The Slough House formula: misfits as antiheroes

Where traditional spy narratives orbit sleek agents and flawless missions, Herron centers on a dormitory of underachieving operatives who have fallen out of favor with the perfection of the bureau. Headed by the wry, sharp-tongued Jackson Lamb, Slough House is the place where failed operations end up not with a flourish but with a messy truth—the kind of truth that lurks beneath the surface of any grand espionage plot.

This cast—described in the books with a mix of cynicism and affection—reframes the spy genre. By focusing on bureaucratic bungling and moral ambiguity, Herron exposes the gaps, the delays, and the human flaws that real intelligence work can entail. The novels blend political satire with a burlesque office comedy, delivering tension and humor in equal measure. It was a gamble: critics praised the concept, but the market’s readiness for such a burlesque turned out to be uneven. The early reception was strong, yet the first edition did not immediately become a bestseller. Still, the appeal of Slough House endured, and slowly, the audience grew—hungry for a spy tale that felt both honest and acerbically entertaining.

From page to screen: Slow Horses on Apple TV+

The real turning point arrived when the books found a larger stage through television. Apple TV+ adapted Herron’s universe with a deft touch, thanks in part to writer-producer Will Smith, known for Veep and The Thick of It. The series preserves the books’ spirit: brisk dialogue, a subversive sense of humor, and a tense, puzzle-like plot where the stakes extend beyond a single mission. The standout performance of Gary Oldman as Jackson Lamb anchors the show, delivering the character’s junkyard charisma with unsettling fluency.

Just as Herron’s novels gained resonance with readers in the Brexit era, the TV adaptation struck a chord with a wider audience. The combination of espionage and satire—coupled with a memorable ensemble—has helped Slow Horses become a streaming unicorn: a critically acclaimed series that also attracts a broad, ongoing audience. There’s already talk of continued seasons, with Oldman confirming ongoing involvement and new seasons in production. The adaptation demonstrates how a sharp literary premise can translate into a potent televised experience without losing its bite.

Why the series feels contemporary—and timeless

Herron himself has noted an unsettling truth: no matter how far fiction advances, reality often outpaces it. In the last few years, as political events have unfolded with a pace that rivals a thriller, Slow Horses has managed to stay one step ahead by merging spy intrigue with a clear, darkly comic portrait of a dysfunctional bureaucracy. The books’ bedside manner—gritty, witty, and morally ambiguous—has allowed the series to age with the moment, turning politics into the backdrop for character-driven suspense rather than the loud center stage of plot-driving melodrama.

In a cultural moment hungry for smart, character-led storytelling, Slow Horses is more than a spy series; it’s a commentary on institutions, leadership, and the human cost of failure. Herron’s loyal readers found a bridge from page to screen, and the show’s reception suggests that the Slow Horses phenomenon is far from over. As new titles roll out—most recently Clown Town, the ninth novel—fans anticipate how the misfit squad will navigate a world that continues to surprise, alarm, and entertain in equal measure.

Looking ahead: what comes next

With each new installment, the Slough House crew tests the boundaries of what a spy story can be: witty, intimate, and unwilling to sugarcoat the uglier realities of espionage. For viewers and readers, the promise remains the same: a smart, unsparing look at the people who do the work of keeping secrets—and at the price they pay for it. If the past is any guide, Slow Horses will keep evolving, delivering fresh intrigue while staying true to its disenchanted, lovable misfits.
