Slow Horses Author Mick Herron Promises More Books Are on the Way

Mick Herron, best known for his Slow Horses (aka Slough House) series, has reassured fans that the story is far from over. Though he’s already mapped out the eventual demise of his lead character, Jackson Lamb, Herron says there are still many tales left to tell before that happens. The author’s comments arrive amid growing anticipation following the success of the television adaptation on Apple TV+.

Planning Lamb’s Final Fate — But Not Yet

During a Guardian literary event, Bleeding Cool reports that Herron revealed he has “already figured out when Jackson Lamb would finally die,” yet made it clear that readers—and viewers—should not expect that moment any time soon. In that same interview cycle, he added reassurance about the series’ continuation: “There will be more to come,” Herron told Radio Times. “I haven’t decided how many yet, but I’m enjoying myself and don’t plan to stop just yet.”

While the eventual endgame is in his mind, Herron is clearly not rushing to get there. The slow-burn nature of Slow Horses has always emphasized character, moral ambiguity, and institutional rot over big set-piece thrills—and it’s a pacing he seems determined to maintain.

Promised Slow Horses Novels Beyond the Known

Herron’s commitment to extending the series is welcome news to fans who feared Lamb’s fate might prematurely close the door on further installments. As Bleeding Cool put it, “he has since promised that he is planning to write several more novels in the series” before concluding the saga, “which should be a relief to readers.”

The prospect of multiple future books means the world of Slough House will continue to expand, possibly exploring other characters, operational challenges, and surprising internal betrayals.

The Slow Horses television series has helped broaden Herron’s audience. With its critical acclaim and extended multi-season commission, the show raises expectations for the books, too. Herron’s recent novel, Clown Town, is a sharp example: set partly in the present and partly decades earlier, it grapples with moral complexities involving intelligence operations, the Troubles in Northern Ireland, and the lasting repercussions of those tangled histories.

Given the alignment between the books’ dark tone and the show’s gritty realism, fans might reasonably expect future novels to continue in the same vein of introspection, institutional critique, and flawed heroism.

What Lies Ahead

Will Lamb survive to retire peacefully, or will the Slough House operation continue under a new torchbearer? Herron alone knows where the path leads. But with the author’s renewed promise of more books on the way—and his acknowledgment that he’s still finding joy in writing—it seems readers have many more twists and betrayals ahead.
