When innkeeper Dorthe Hyllested is found murdered, the police are surprised and puzzled to discover a concealed nursery in her upstairs apartment. As far as her friends and family knew, the recently widowed Dorthe was childless—so who lived in this secret toy-strewn room? And more importantly, where is the child now?

Detective Louise Rick has just taken on a challenging new job as head of the freshly created Mobile Task Unit, which is charged with solving the most difficult cases all over Denmark. With Dorthe’s murder as her first investigation and the clock ticking to find the missing child, Louise is dismayed to learn that none of her handpicked group of seasoned investigators have been approved for transfer to her new unit. Instead, she must cobble together a brand-new, unproven team from a group of officers she’s never met. Worst of all, the case will necessitate collaborating with the Missing Persons Department—which will mean working closely with Louise’s former fiancé, Eik, who abruptly broke things off last year, leaving her devastated.

Could the mystery of Dorthe’s murder and the hidden child have something to do with the cabin in the woods behind the inn where men are often seen coming and going at all hours? With no witnesses to Dorthe’s murder and no real leads, and an unproven and potentially untrustworthy team behind her, Louise finds herself grasping at unlikely connections—but the twisted story she begins to uncover turns out to be darker and more dangerous than she ever imagined. . . .
