Everything is peaceful in Tommerup, Denmark, until a young mother disappears in the middle of an idyllic summer day. There's no trace of the missing woman when Chief Superintendent Liam Stark and Superintendent Dea Torp are called to investigate. The small town is on edge, rumors begin to fly, and blame is cast on Charlotte's husband, who was the last to see her. When another person goes missing and Liam and Dea find a strange note linking the second missing person to the first crime, they suspect the disappearances may be the work of a serial killer.

As the investigation continues, dark secrets about the victims from the past are revealed. Is someone targeting them because of this? As more people vanish, it's a race against time for Liam and Dea, who find themselves face-to-face with horrifying footage that reveals what is happening to the victims--and what will happen to future targets if they can't stop the killer.

In this pulse-pounding thriller, Sara Blædel and Mads Peder Nordbo ratchet up the tension in a cat-and-mouse game where the killer is always one step ahead.
