The chestnut man

The chestnut man. The police make a terrible discovery in a suburb of Copenhagen. A young woman has been killed and dumped at a playground. One of her hands has been cut off, and above her hangs a small doll made of chestnuts. Young detective Naia Thulin is assigned the case. Her partner is Mark Hess, a burned-out investigator who's just been kicked out of Europol's headquarters in The Hague. They soon discover a mysterious piece of evidence on the chestnut man - evidence connecting it to a girl who went missing a year earlier and is presumed dead, the daughter of politician Rosa Hartung. A man confessed to her murder, and the case is long since solved. Soon afterwards, another woman is found murdered, along with another chestnut man. Thulin and Hess suspect that there's a connection between the Hartung case, the murdered women and a killer who is spreading fear throughout the country. But what is it? Thulin and Hess are racing against the clock, because it's clear that the murderer is on a mission that is far from over.
