At first the prisoner scratches at the walls until her fingers bleed. But there is no escaping the room. With no way of measuring time, her days, weeks, months go unrecorded. She vows not to go mad. She will not give her captors the satisfaction. She will die first. Copenhagen detective Carl Mørck has been taken off homicide to run a newly created department for unsolved crimes. His first case concerns Merete Lynggaard, who vanished five years ago. Everyone says she's dead. Everyone says it's a waste of time. He thinks they're right. The voice in the dark is distorted, harsh and without mercy. It says the prisoner's torture will only end when she answers one simple question. It is one she has asked herself a million times: WHY is this happening? A dark and mysterious story, Mercy establishes Jussi Adler-Olsen as the master of the Nordic thriller.

In The Keeper of Lost Causes, Jussi Adler-Olsen introduced Detective Carl Mørck, a deeply flawed, brilliant detective newly assigned to run Department Q, the home of Copenhagen’s coldest cases. The result wasn’t what Mørck—or readers—expected, but by the opening of Adler-Olsen’s shocking, fast-paced follow-up, Mørck is satisfied with the notion of picking up long-cold leads. So he’s naturally intrigued when a closed case lands on his desk: A brother and sister were brutally murdered two decades earlier, and one of the suspects—part of a group of privileged boarding-school students—confessed and was convicted. But once Mørck reopens the files, it becomes clear that all is not what it seems. Looking into the supposedly solved case leads him to Kimmie, a woman living on the streets, stealing to survive. Kimmie has mastered evading the police, but now they aren’t the only ones looking for her. Because Kimmie has secrets that certain influential individuals would kill to keep buried . . . as well as one of her own that could turn everything on its head.
