First reviews of The Sleepwalker

"Knox’s pitch-black novels are among crime fiction’s most compelling" (i)

"Fierce, funny and flint-sharp. Joseph Knox is the true grit of Brit noir" (Cara Hunter)

"Dark, gritty and compelling, this will have you turning the pages until the early hours of the morning" (The Independent)

"Oozing dread, full of surprises and with a powerful sense of outraged humanity, The Sleepwalker is Joseph Knox’s finest novel yet." (The Times)

"‘[An] ingenious plot … full of striking revelations’" (CrimeTime)


The Smiling Man, Joseph's second novel featuring Detective Aidan Waits, is now available in book shops and online. 

The Smiling Man reviewed:

'Knox writes electric novels. A major voice in fiction, and a writer of furious talent.' (A.J. Finn, author of The Woman in the Window)

'Knox’s first novel was pedal-to-the-floor stuff, and this is even more powerful. One thing is sure: Knox is no one-hit wonder.' (Barry Forshaw, The Guardian)

'If you liked Sirens, you will love The Smiling Man. Gritty, noir, and packing a punch from the very first page.' (Jane Harper, author of The Dry)

'Written with Knox’s powerful descriptive prose and underpinned with black humour, a plot full of perfectly gathered threads, and a bone-chilling, gut-wrenching intensity, this remarkable thriller is proof of an author with far more than one ‘big’ book to his name.' (Pam Norfolk, Lancashire Post)


Sirens is Joseph's debut novel. Available now at local book stores and online:

Sirens reviewed:

'Razor-sharp urban noir – very special indeed.' (Lee Child)

'Thrilling, breathless stuff.' (The Observer)

'Sirens immediately feels like a classic, not a debut . . . a book for every crime fan.' (Julia Heaberlin, author of Black Eyed Susans)

'Sirens is the best British crime debut of the last five years.' (Crimescene Magazine)

'Sirens is a powerhouse of noir. Joseph Knox owns Manchester and paints it in all its grimy colours.' (Val McDermid)

'Manchester throbs with lowlife in this startling debut . . . a page-turner with a beating heart. I loved it.' (Sarah Hilary)

'Knox presents the city as pungently and uncompromisingly as Ian Rankin does Edinburgh.' (The Guardian)

'A firecracker of a crime tale. His writing is taut, atmospheric and studded with eye-catching descriptions. An arresting new talent.' (Metro)
