Small-town police detective Hanna Duncker has a past. Her deceased father was convicted of murder and arson long ago, and she has taken up residence and resumed her police career in her hometown after his death. She and her partner, Erik Lindgren, are called to investigate the disappearance of a father and his infant son from their home while his wife was away on a weekend trip. As the investigation unfolds, Hanna makes a breakthrough in her ongoing private investigation of her father’s crimes: a discovery that could change everything she thought she'd learned so far.

Police detective Hannah Duncker didn’t expect to return to her native Öland. She fled after her father’s murder conviction and returns to make peace with her shame. She has a new job with the local police and a nosy new partner. A 15-year-old’s death catapults her into a murder investigation that resurrects ghosts from her previous life. As she hunts for the truth, she must confront the people she abandoned. Not all are pleased to see her back home, and she soon learns that digging through the past comes with consequences.
