• "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
  • "Gritty as hell. I loved it! A great urban cop thriller"

    Ian Rankin
  • "Sirens was one of the best books published last year and this intense, blackly comic follow-up is just as good. Joseph Knox has conjured up a sense of evil and corruption you can almost smell it."

    Jake Kerridge, Sunday Express
  • "Razor-sharp urban noir – very special indeed."

    Lee Child
  • "Imperfect as Aidan Waits is, the Manchester DC is the shining light in a world peopled by the worst kinds of bad people. This is Knox's second Waits book in what holds the promise of a classic series."
