A young woman is found strangled in a park, and a male journalist has been killed in the backyard of the Royal Hotel in Copenhagen. Detective Louise Rick is put on the case of the young girl but very soon becomes entangled in solving the other homicide, too, when it turns out her best friend, journalist Camilla Lind, knew the murdered man. Louise tries to keep her friend from getting too involved, but Camilla's never been one to miss out on an interesting story. And this time, Camilla may have gone too far.

It's clearly no ordinary drowning. When a young girl is pulled from the watery depths, a piece of concrete tied around her waist and two mysterious circular patches on the back of her neck, Detective Louise Rick is immediately called out to Holbaek Fjord. Her name was Samra, and when the police learn that she was a member of Holbaek's sizeable Muslim immigrant community, they immediately assume it was an honor killing. Yet her mother insists Samra had done nothing dishonorable.

A journey to a new life or a prison of despair and death? A shocking murder on Copenhagen's idyllic streets and an abandoned child reveal a perverse criminal underworld that crosses international borders. A young woman's body is found on the street with her throat slit, and the media is clamoring for the grisly details. Detective Louise Rick is investigating the gruesome murder when her friend Camilla Lind calls. Louise assumes it is because Camilla, a crime reporter, wants to be the first to hear of any juicy new developments.  

The only witness to a shocking murder is the victim's 10-year-old daughter, Margret. The police turn to the Children's House for their expertise in childhood trauma. The manager, Freyja, doesn't much like the police - especially the detective in charge, Huldar. But she does want to help them protect Margret. And when more people die - their murders heralded by strange messages, texts, and strings of numbers - they will have to work together to crack the riddle before they become targets themselves.

Detective Louise Rick gets a call from her son, Jonas. A school party has ended in terrifying chaos after a group of violent teenagers forced their way into the building in search of alcohol and valuables. Arriving at the scene, Louise discovers that one of the girls, 12 year-old Signe, attempted to run for help, but was struck and killed by a car. Signe's grief-stricken mother finds that her will to live instantly evaporates with the crushing loss of her only child - and she'll do anything to make those who harmed her child pay.
