Every Wednesday since the middle of September, Gary Oldman has been scratching, belching and insulting his way through another episode of Slow Horses, and few of the people watching could pick the man who invented Jackson Lamb out of a crowd. Mick Herron seems to prefer it that way. For most of his writing life he was a subeditor on an employment-law bulletin in London, catching the train home to Oxford and giving fiction whatever hour was left in the evening.

That commute produced what many critics now call the best British spy fiction since John le Carré. The Slough House books follow a squad of domestic intelligence officers exiled for their blunders to a shabby building in Islington, far from headquarters at Regent’s Park, where they are supposed to die of boredom and instead keep stumbling into the real business of the Service. Herron is funny about failure in a way the genre had rarely allowed, and just as serious about what that failure costs.

Michael Herron was born in Newcastle upon Tyne on 11 July 1963, one of six children of an optician and a nursery-school teacher. He read English at Balliol College, Oxford, wrote poetry before he wrote novels, and stayed in the city, where he still lives. The day job, subediting the IDS Employment Law Brief for Incomes Data Services, lasted until 2017. He would get home at around six and write for an hour.

He started with crime. Down Cemetery Road (2003) introduced Zoë Boehm, a sardonic Oxford private investigator, and three more Boehm novels followed by 2009. Then came the London bombings of 7 July 2005. Commuting into the city where the attacks had happened, Herron began thinking about the security services, and specifically about the people inside them who get things wrong. The result was Slow Horses, published by Constable in 2010.

It did not sell. Constable turned down the sequel for the British market, and the series kept going thanks to Soho Press in the United States. Dead Lions won the Crime Writers’ Association Gold Dagger in 2013, and John Murray began reissuing the books in the UK from 2015. The run that followed kept collecting prizes and shortlists: Real Tigers, Spook Street (winner of the CWA Ian Fleming Steel Dagger in 2017), London Rules and Joe Country. In 2022 the seventh book took the Theakston Old Peculier Crime Novel of the Year award.

Jackson Lamb is the engine. Herron has said the character owes something to Reginald Hill’s Andy Dalziel, and he once told The Guardian that he looks at Lamb and thinks, “My God, did I write that? My mother reads this stuff!” A flatulent, chain-smoking Cold War veteran who appears to do nothing all day, Lamb protects his so-called slow horses with a ferocity he would never admit to. Around him Herron builds a precise satire of Whitehall: budget wars, leaks timed for the morning papers, Diana Taverner scheming at Regent’s Park, and junior officers left to pay for decisions taken far above them.

Herron never worked in intelligence, and he treats that as an advantage. His Service runs like any other office, petty and underfunded, full of people doing tedious work beside colleagues they cannot stand. He started reading le Carré at fourteen, and the debt shows in the moral weather of the books, but the tone is his own: sentences that swerve from a joke into a death without changing pace. In 2022 Jill Lepore asked in The New Yorker whether he was the best spy novelist of his generation, and the question has stuck to him ever since.

Television made him famous. Apple’s Slow Horses launched in April 2022 with Oldman, who had played George Smiley in the film of Tinker Tailor Soldier Spy, as Lamb, and Kristin Scott Thomas as Taverner. The adaptation has won the USC Scripter Award for television twice, and in September Saul Metzstein took the Emmy for drama directing for the finale of the fifth season. The sixth, which premiered on 16 September and ends on 21 October, folds Joe Country and the seventh novel into six episodes. Apple has already renewed the show for an eighth season, built on Clown Town.

The rest of his shelf is getting the same treatment. Down Cemetery Road arrived on Apple TV in October 2025 with Emma Thompson as Zoë Boehm and Ruth Wilson as the woman who hires her, and a second season was announced that December. On the page, Herron has kept widening the world: Bad Actors (2022), the standalone The Secret Hours (2023) and Clown Town (2025), a blackmail plot rooted in the Troubles that landed on several best-of-the-year lists. On 22 October Watch the Quiet Snow gathers the five Slough House novellas in a single hardback.

The establishment has caught up too. Herron was elected a Fellow of the Royal Society of Literature in 2024, and in 2025 the Crime Writers’ Association gave him the Diamond Dagger for a lifetime’s work, a prize le Carré himself once received. He is still in Oxford, still writing. The difference is that the people on his old train now know exactly who the slow horses are.
