Seventeen years ago, Criminal Inspector Ewert Grens was called to the scene of a brutal crime. A family had been murdered, and the only survivor—and witness—was the five-year-old daughter. The girl was placed in the witness protection program, and the case went cold, but years later, Grens is still haunted by the seemingly random slaying, and the little girl who was spared. So when he learns that the apartment where the crime occurred is now the scene of a mysterious break-in, Grens immediately fears that someone is intent on silencing the only witness. He races to find her...before they do.
Grens is an immensely compelling character whose sharp intuition and dedication to justice are reminiscent of Harry Bosch. This tense, sophisticated procedural can stand alone, but readers will find themselves drawn to Grens’ seven earlier investigations.
With a story stretching from Stockholm to Montenegro and back, this is definitely a tense and detailed thriller, giving some interesting highlights into Swedish policework and their use of undercover agents ... Though not overly violent, the ending is a twist and a shocker, and only a reader skilled in picking out details will guess this story’s finish. The last three sentences resonate with sad and shocking irony.
Knock Knock would be noteworthy solely for the fact that it is Anders Roslund’s debut novel ... Knock Knock continues the Roslund/Hellström series featuring Stockholm Criminal Inspector Ewert Grens and former police informant turned security expert Piet Hoffman. I am happy to say that it meets and exceeds the expectations created by its predecessors ... shot through with images and scenes that are impossible to forget and are intertwined with a number of suspenseful vignettes. 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.
