Amazing reviews of 'Den Sindssyge Polak' (The Night Ferry)

June 2014


”a terrific, thrilling and gripping novel with strong emotions and powerful political tones.”

”A novel of high international standard. And a novel that could - and should – make it to the big screen.”

”I was caught from first till last page and couldn’t put the book down, despite the fact that I wanted to save some pages for special moments. ’The Woodman’ is a thriller about deceit and betrayel, about intrigues and manipulation and political cynicism – all very realitically done.”
- Politikken


”Hammer and Hammer are linguistic naturals in the league of Arne Dahl and Håkan Nesser.”

”They can deliver a plot with one surprising twist after the other. And how refreshing for once in the genre, that both good and evil in society’s elite is depicted.”
- Jyllandsposten

”Not just a terrifically thrilling crime novel, but also an insight into what it is like for veterans to live with their traumas – without getting the necessary help.”
- Ugebladet Søndag


”The siblings Lotte and Søren Hammer take a tough stance in the fifth book in their crime series with the likeable Chief Detective Inspector Konrad Simonsen and his team from the Homicide Division in Copenhagen.”
- Dagbladenes Bureau
