About this book

Book Summary

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 Cartwright, long buried, has left his library to the Spooks' College in Oxford, and now one of the books is missing. Or perhaps it never existed. 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 starts investigating the secrets of his grandfather's library.

Over at the Park, MI5 First Desk Diana Taverner is in a pickle. An operation carried out during the height of the Troubles laid bare 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. All she needs is the right dupe to get caught holding the bag.

Jackson Lamb, the enigmatic and odiferous head of Slough House, 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.

Media Reviews

"Overflowing with gritty action and mordant humor, this is as good as espionage novels get." —Publishers Weekly (starred review)

"The best news of all: The climax leaves the door open to further reports from the hilariously misnamed British Intelligence." —Kirkus Reviews (starred review)

"Since he first introduced the misfit spies of Slough House in 2008's Slow Horses, Herron has been compared to the likes of Graham Greene, Len Deighton, and John le Carré. But Herron's stories are entirely unique, and his writing style is unlike anyone else's, with a deliciously satirical edge...If there are any spy-fiction fans who haven't yet read Herron's books, now's a good time to rectify that." —Booklist
