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

Wall Street Journal

A perfect example of Scandi noir

The Times

[A] complex, white-knuckle read

- Alison Flood, Observer

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

New York Times Book Review

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

The Bookreporter

From the first <i>Knock Knock</i> on the door of a murder scene to discovering the killers behind it, this novel is a breathless, suspenseful read...A <b>heart-pounding thriller</b>... 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.

Shelf Awareness
