Spies lie. They betray. It's what they do.

Slow horse River Cartwright is waiting to be passed fit for work. With time to kill, and with his grandfather - a legendary former spy - long dead, River investigates the secrets of the old man's library, and a mysteriously missing book.

Regent's Park's First Desk, Diana Taverner, doesn't appreciate threats. So when those involved in a covert operation during the height of the Troubles threaten to expose the ugly side of state security, Taverner turns blackmail into opportunity.

Over at Slough House, the repository for failed spies, Catherine Standish just wants everyone to play nice. But as far as Jackson Lamb is concerned, the slow horses should all be at their desks.

Because 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 and fool around, any harm that befalls them is hardly his fault.

But they're his clowns. And if they don't all come home, there'll be a reckoning.

Critic reviews

Masterly
Clown Town is a masterpiece (India Knight)
Over the last decade this series of novels about a community of cashiered spies has made the transition from "well-kept secret" to "household name". Herron is now an authentic megastar of the genre . . . It's Herron's line-by-line writing that really makes [the books] stand out. Has there been a more magnificently bossy narrative voice since Dickens? Or one more in love with the baroque flourish? (Sam Leith)
No one can rival Mick Herron . . . the series is increasingly acquiring a seriousness of heart that befits Herron's achievement
Funny, thrilling and shot through with real anger at the state of the nation
This isn't just a superb thriller about dysfunctional spooks. In these dark days, there are not many novels of any sort that make you laugh aloud. But this is one of them
Intricate plots of simmering tension, an intelligence service that hums with mundanity and mendacity, and X-rated dialogue delivering character assassination with every withering riposte. . . a series that continues to reinvigorate the spy fiction genre
Laced with Herron's mordant wit and whip-crack dialogue . . . Herron knits the threads together with his familiar verve
The jokes are as good as ever, the writing is glorious, the plot is deviously clever and the glimpses of real history add a layer of seriousness to the story . . . superb novel
A fabulous, funny book with a delicious sting in the tail
A twisty, comic tale centred on a covert operation from the heigh of the Northern Ireland Troubles
Herron at his masterly best, a stylish page-turner . . . the tales of the Slow Horses have matched the muddle, shoddiness and loss of status of post-Brexit Britain
Herron again blends satire with politics and page-turning pacing
Mick Herron has that rare gift of being able to write exquisitely and hilariously while keeping us on the edge of our seats. An IRA double agent and a corrupt politician are central to this story while Diana Taverner and Jackson Lamb slug it out once again. Thoroughly enjoyable, I now have a whole new bunch of insults to add to my collection (Liz Nugent, author of STRANGE SALLY DIAMOND)
Pure class: thrilling, funny and moving. By now it's obvious that the Slough House novels are not just suspenseful, laugh-out-loud entertainments, not just literary marvels, but important too, essential stories of the state of the UK in the twenty first century (Simon Mason, author of A VOICE IN THE NIGHT)
Clown Town is an absolute belter. No one is better than Mick at loading exactly the right words and taking aim at the egos and idiocies in Westminster and further afield. More satisfying than a squirty flower in the face of your least favourite politician (Sarah Hilary, author of SHARP GLASS)

As good as ever, though the main event was foreshadowed almost from the first page. Not sure what was up with the narration in part one but part two was a lot more up to standard. I’m not sure but this feels like an ending. I hope not.

Wow

I thought it was me - I was having so much difficulty understanding the 'accent' or 'poor diction' of the narrator. But I think this does Sean Barrett a dis-servie and actually it's some kind of problem with the audio quality as others have said. Makes this quite a hard listen - esp if like me you listen when you are out and about and there are ambient sounds. I'm a Mick Herron fan and this is a disappointment - I may even return the book to Audible - something I have almost never done. But I'm also keen to know what happens next in he plot. 50/50 whether I'll be able to finish the book or not. I'm hoping to hear Mich Herron talk about Clown Town at the Chetenham Literatur Festival in a few weeks time. I wonder if he'll be asked about this issue????

Really struggling with the audio quality

9th book in and still surprised by the twists. He knows how to keep you coming back for more. Looking forward to the next one!

Still got it.

Great spy thriller, yet again, but a spy novel that has so much dark and well written humour in it that I have spent the last couple of days walking around London listening, laughing out loud to myself in public, to the consternation of passers-by.
Sean Barrett is the perfect narrator for this series. Great job!

Murderously funny

The narrator is fantastic, the writing is phenomenal. I didn’t think this series could continue to improve but it does. Each new story adding a delicious layer to these wonderfully flawed and (in many ways) endearing characters.

Astonishingly good. Roll on the next one!
