Callum McSorley is a writer based in Glasgow whose short stories have appeared in Gutter Magazine, Monstrous Regiment and New Writing Scotland. Squeaky Clean was his debut novel, inspired by his years working at a car wash in Glasgow's East End. With it, Callum won the prestigious McIlvanney Prize for best Scottish crime novel of the year. Paperboy is the second Ally McCoist thriller. It follows the reputationally-challenged detective as she investigates a murder linked to a confidential paper-shredding business and stumbles across evidence of police corruption ? the sort of evidence that could get her killed if she doesn't handle it carefully...

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
