THE NINTH BOOK IN THE SERIES BEHIND SLOW HORSES, AN APPLE ORIGINAL SERIES NOW STREAMING ON APPLE TV+

Jackson Lamb and the bad spies of Slough House are caught in a deadly battle between MI5's secret past and its murky future in this gripping, hilarious, and heartbreaking thriller by Mick Herron, “the le Carré of the future” (BBC).


“Old spies grow ridiculous, River. Old spies aren’t much better than clowns.” Or so David Cartwright, the late retired head of MI5, used to tell his grandson. He forgot to add that old spies can be dangerous, too, especially if they’ve fallen on hard times—as River Cartwright is about to learn the hard way.

David, long buried, has left his library to the Spooks’ College in Oxford, and now it turns out that one of the books has gone missing. Or perhaps it never existed. Now River, once a “slow horse” of Slough House, MI5’s outpost for demoted and disgraced spies, has some time to kill while awaiting medical clearance to return to work, and investigating the secrets of his grandfather’s library seems a harmless activity. But nothing involving the slow horses ever stays harmless for long.

Over at the Park, MI5 First Desk Diana Taverner is in a pickle. An operation carried out during the height of the Troubles revealed the ugly side of state security, and those involved are threatening to expose details. But every threat hides an opportunity, and Taverner has come up with a scheme in which the would-be blackmailer is a solution to a much newer problem. All she needs is the right dupe to get caught holding the bag.

Jackson Lamb, the enigmatic and odoriferous head of Slough House, does not want any of his joes involved. When Taverner starts plotting mischief people get hurt, and Lamb has no plans to send in the clowns. On the other hand, if the clowns ignore his instructions, any harm that befalls them is hardly his fault.

But they’re his clowns. And if they don’t all make it home, there’ll be a reckoning.
Praise for the Slough House Series

“What spurs me to keep reading each new installment is Herron’s absurdist voice, which could devolve into cheap cynicism but never does. That’s why the Slough House denizens, from Jackson Lamb to Roddy Ho to newcomer Ashley Kahn, maintain pathos in the face of parody—they may be bitter, but they have pride in themselves and their work.”
The New York Times Book Review

“Intricate plotting, full of twists . . . Herron can certainly write a real spy story, with all the misdirection and sleight of hand that requires. But it’s the surly Slough House mood, the eccentric characters, and Herron’s very black, very dry sense of humor that made me read one after the other without a break.”
—Slate.com

“I'll tell you what, to have been lucky enough to play Smiley in one's career; and now go and play Jackson Lamb in Mick Herron's novels—the heir, in a way, to le Carré—is a terrific thing.”
—Gary Oldman

“Confirms Mick Herron as the best spy novelist now working.”
—NPR's Fresh Air


“Compulsively readable, tightly plotted.”
Los Angeles Times

“Out of a wickedly imagined version of MI5, [Herron] has spun works of diabolical plotting and high-spirited cynicism, their pages filled with sardonic wit . . . Happily for Mr. Herron—if alas for us—events continue to produce rich material for his special gifts, and we hope he is scribbling away making good use of it all.”
The Wall Street Journal

“Heroic struggles, less-heroic failures and a shoot-out-cum-heist . . . with no let-up in the page turning throughout.”
Esquire

“The best in a generation, by some estimations, and irrefutably the funniest.”
The New Yorker

“Herron’s strength is in examining at close hand the absurdities, conflicts, and dangers of the intelligence agency as an institution at the center of some of the most central conflicts in the 21st century.”
