Detective Thomas Ravnsholdt, known as Ravn to friends and colleagues, is suspended from the police force since a breakdown he suffered after the murder of his girlfriend, Eva. Full of self-reproach over Eva’s death, Ravn escapes into devastating alcohol binges on his old boat in Christianshavn Canal in the center of Copenhagen. He is yanked out of his drunken despair when a close friend asks for help in finding a young woman who disappeared a few years earlier. The search forces Ravn back to his old workplace – although now as a private investigator – and down into the seedy underbelly of Copenhagen. Everything indicates that the girl has been sold to notorious trafficker Gusto Slavros, who has a network of brothels all around Europe. Since the traces of the girl lead to Stockholm, to a place darker than hell, Ravn reluctantly takes off on the dangerous journey. In a race against time he tries to find out if the girl is still alive. Ravn’s investigation is further complicated by an artistic serial killer who for years has ravaged Stockholm: a sadist who arranges his victims – all young prostitutes – like terrifying statutes on the city’s garbage dumps, and who is now setting his sights on his next victim…

Derailed is the first part of a new series about the skilled but self-destructive private investigator Ravn, based in Copenhagen.

Derailed is shortlisted for the Danish award MARTHA prisen 2014.


Unusual protagonist and well-composed action. The new crime series from one of Denmark’s best suspense writers is a very pleasant and suspenseful acquaintance. /…/ Again, Krefeld delivers an all-out superior and very convincing piece of work. /…/ Danish crime fiction at it’s best.
Litteratursiden, Denmark

Efficient and hardboiled.
Jyllands-Posten, Denmark

A tight plot crafted with high-voltage /…/ Just like a true bestseller should be. /…/ Derailed is like an incendiary flame, which gives the readers heated, sleepless nights.
Berlingske, Denmark

A story that maintains the suspense all the way – not least thanks to a well-composed cast of characters; from Ravn’s urban village setting by the Christianshavn Canal to the Eastern European gangsters, the abused women, and a few finely drawn cop colleagues in the periphery. Language and intrigue are successfully tightened up, giving the story energy, presence and nerve. /…/ This may well become a really good series.
Ekstra Bladet, Denmark

Ravn is a truly delightful acquaintance that there is a good reason to follow. With Derailed Katz Krefeld shows that he is still in the league he landed in last year when he received the Danish Crime Academy’s award for the Best Crime Novel of the Year: Among the best.
Politiken, Denmark

Michael Katz Krefeld tackles familiar themes, but he gives them his distinctive, rather foul colors. The protagonist, Ravn, is psychologically exciting, and he will without doubt be able to maintain the interest for several more volumes.
Dagbladenes Bureau, Denmark

Frightens enough for several sleepless nights /…/ Ravn is an acquaintance one wants to know more about.
Alt for Damerne, Denmark

The adrenaline boils all the way through… The suspense hits the red zone. The author has a relentless and firm grip on his reader. /…/ Come on, Krefeld, many of us are excitedly awaiting [the next installment].
Fyns Amts Avis, Denmark

Paints the picture of the derailed world of people, values and institutions with an exceptional care for the attraction of the crime plot, dynamism of the action and clarity and vividness of the narrative. Consequently the writer joins the ranks of those whose subsequent books we are impatiently waiting for.
Kryminalnapila, Poland

Book of the day! A convincing thriller for those who love the Scandinavian crime genre
