'... a twisty and tense exploration of family secrets, survival, and the often blurred lines between fantasy and reality and predator and prey... Readers will likely think they know where this runaway train is headed, making the final twists that much more surprising… A creepy and darkly addictive thriller.'

'Beautifully crafted as you would expect - Barnett is a pseudonym for an unidentified bestselling author - it piles revelation upon revelation with devastating effect, leaving the reader gasping. If you think you can predict what's going to happen, think again. It is that good.'

A tense and detailed thriller...The ending is a twist and a shocker.

[Grens is] an eccentric, alienated, socially inept hero worthy of comparison with Swedish mystery master Henning Mankell's Inspector Kurt Wallander.

A perfect example of Scandi noir

[A] complex, white-knuckle read

If you thrill to the chills of Scandinavian noir, chances are you've read something by Anders Roslund. Roslund has two strong prose styles - dark and darker - and both are on show in Knock Knock.

Anders Roslund is a household name throughout most of the world as a master of crime fiction, and this book is a sterling example of why.

From the first Knock Knock on the door of a murder scene to discovering the killers behind it, this novel is a breathless, suspenseful read...A heart-pounding thriller... Roslund's serpentine plot and visceral character development brings each cliffhanging chapter to a staggering revelation on how tasty a dish of cold, karmic revenge can be.

Heart-pounding...This terrific mash-up of police procedural and crime thriller has strongly imagined characters, explosive action, and a twisty plot with an unexpected conclusion. It's a must for Scandinavian noir fans.

Grens is an immensely compelling character whose sharp intuition and dedication to justice are reminiscent of Harry Bosch... a tense, sophisticated procedural

An edge of your seat thriller about revenge and treachery during three fateful days.

Has punchy prose and plot twists that readers expecting another brooding Scandinavian noir won't see coming
