Early 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)


Joseph’s new novel featuring Aidan Waits is available in book shops now.

‘He said he didn’t remember killing them…’   As a series of rolling blackouts plunge the city into darkness, Detective Aidan Waits sits on an abandoned hospital ward, watching a mass murderer slowly die. Transferred from his usual night shift duties and onto protective custody, he has just one job…  To extract the location of Martin Wick’s final victim before the notorious mass murderer passes away.  Wick has spent over a decade in prison, in near-total silence, having confessed to an unspeakable crime that shocked the nation and earned him the nickname of  The   Sleepwalker .  But when a daring premeditated attack leaves one police officer dead and another one fighting for his life, Wick’s whispered last words will send Waits on a journey into the heart of darkness…  Manipulated by a reticent psychopath from his past, and under investigation from his new partner, Detective Constable Naomi Black, Waits realises too late that a remorseless contract killer is at work.  Can Aidan Waits solve his last case before fleeing justice?   Or will his name be next on the hit list?
