'The vibe is Taggart rewritten by Mick Herron' The Times

DCI Alison McCoist is up to the oxters in Glasgow's shadiest police unit, with a list of guilty secrets growing longer by the day.

Fran Forbes has just bolted from the scene of a gangland massacre with only a shite-stained tracksuit and a memory stick full of cryptocurrency to his name.

Ally is tasked with looking into this latest underworld rammy and ends up working with some bampots even dodgier than her polis pals. Can she keep Fran from being turned into mince by a Russian OCG and finally free herself from the fankle of police corruption she's caught in? An enemy from Ally's past is determined her story won't have such a happy ending...



Callum McSorley is a writer based in Glasgow, where he grew up. His debut thriller, Squeaky Clean, was published to great acclaim and went on to win the prestigious McIlvanney Prize for best Scottish Crime Book of the Year. The second Ally McCoist thriller, Paperboy, was also shortlisted for the McIlvanney Prize.



Beautifully plotted, chockful of shocks and oozing compassion, Rat Race is the perfect end to an outstanding trilogy. Filth has never been such fun



Like the illegitimate offspring of Irvine Welsh, Chris Brookmyre and Kathy Lette, Callum McSorley's funny, dark and violent take on gangland Glasgow has made him one of Britain's most exciting new crime writers... Fabulous characters, inventive swearing and stacks of gallows humour, the criminal underworld has rarely been so much fun



Rat Race is a full-tilt sprint through the darkest edges of the Glaswegian criminal underground. A viscerally hilarious and sometimes brutal crime thriller, it made me laugh, wince and gasp in equal measure. The inimitable DCI Alison 'Ally' McCoist continues her dangerous dance with the scariest people in the city, intertwining the everyday life of Glasgow with the terrifying violence bubbling just beneath the surface. A triumph of crime fiction and proof that Callum McSorley deserves his status as a rising star of the Scottish scene



Ally McCoist is back! (Not that one.) And this time she's chasing marathon runners, mob bosses and anti-corruption officers, while trying not to get smashed in the face. Authentically "Glesga" with the wit and banter to match, Rat Race is a brilliant thrill ride and an absolute belter of a novel



Oddball, kamikaze and a wee bit unhinged



A hat-trick for McCoist and McSorley, the conclusion to the Glasgow-set crime trilogy is as filthy, furious, and flippant as ever. A multi-layered masterpiece, McSorley brilliantly weaves a compulsive tale of Glasgow gangsters, dirty cops, and the hapless denizens caught between them. Taking in crypto, corruption and toxic masculinity with his trademark caustic wit and sharp eye, McSorley ends his trilogy on a high



A riotously funny roller-coaster ride through the seamier side of life with everyone's favourite detective. Rat Race is a darkly comic triumph



Hilarious and brutal in equal measure, Rat Race solidifies McSorley's status as a top-tier crime writer



A perfect end to a perfect trilogy. The magnificent Ali McCoist stumbles her way through dead bodies galore in hilarious fashion. Both bitingly funny and brutally painful, Rat Race is a masterclass in story-telling and Callum McSorley is as near to genius as makes no difference. Cannot wait to see what he does next



A new novel from McSorley is always cause for celebration. Not only does he know how to spin a yarn, but his prose is fizzy with banter, quips and surprising imagery. I found myself laughing at his deft turns of phrase as often as I gasped at a sudden burst of violence. Scotland has found its Tarantino



Another breathless, hilarious, endlessly-twisting romp through Glasgow's criminal underworld. Viewed through the technicolour lens of McSorley's imagination, Rat Race lives up to its predecessors and then some. Ally McCoist has never been better



An absolute stonker



-- PRAISE FOR CALLUM MCSORLEY



Twisting plots, grotesque lowlifes, black comedy, puns, over-the-top violence - and dialogue that bounces along to the rhythms of Glaswegian street slang



Callum McSorley has doubled down on what made Squeaky Clean such an amazing debut: his second novel is a cavalcade of gruesome violence, a welter of bodily fluids and a torrent of fantastically filthy language... A brilliant black comedy that repeatedly makes you squirm. Fizzing with energy and full of heart, it's one of those books that you simply don't want to end



The vibe is Taggart rewritten by Mick Herron. Gritty gang violence, plenty of black comedy, imaginative plot twists, wonderfully grotesque characters ... and reading them has also expanded my lexicon of insults



Plunges us straight back into the world we were introduced to in the first novel; a world of Weegie gangsters, Glasgow banter and truly horrible deaths. I mean, proper gory deaths. But funny, too. Which means, this is the opposite of cosy crime. The result is very Glasgow and all the better for it



Extremely funny, exciting and ultimately touching



A Glasgow noir that will thrill and amuse those with a wicked sense of humour and a love of gritty crime fiction



Brutally funny and brilliantly plotted, with an engaging cast of characters



The new star of tartan noir



McSorley consolidates his status among crime fiction's rising stars. Paperboy is energetic, inventive and witty, laying on the tension as it builds to a nerve-shredding finale



Just when you're thinking Squeaky Clean is probably the perfect crime novel, along comes Paperboy. The biggest laughs, the seediest urban underbelly, the most irreparably flawed yet inexorably engaging cast
