The Butterfly House

In this chilling Nordic noir thriller set in Copenhagen, detectives Jeppe Kørner and Anette Werner investigate a series of brutal murders tied to a hospital, blending psychological suspense, police procedural, and dark social commentary in this sequel to the #1 international bestseller The Tenant that is "brimming with personality, eccentric characters, and plenty of mystery and intrigue" (Crime by the Book).

Hospitals are places of care-or so it seems. In the coronary unit of a leading Copenhagen hospital, a nurse quietly administers a fatal overdose to an elderly patient.

Days earlier, a paperboy makes a gruesome discovery in the heart of the city: the nude body of a young woman in a fountain, her arms marked by precise incisions, her body completely drained of blood.

Detective Jeppe Kørner, navigating the aftermath of divorce and a fragile new relationship, takes the lead. His partner, Anette Werner-on maternity leave but unwilling to stay sidelined-begins her own unofficial investigation. But working outside the system draws her into increasingly dangerous territory.

As the case unfolds, Jeppe and Anette uncover a horrifying pattern of exploitation and control lurking within caregiving institutions. What they find is as unsettling as it is deadly-and far closer than they ever imagined.

A "thrillingly nerve-racking" (Shelf Awareness) Scandinavian crime novel, this gripping installment delivers a dark, atmospheric mystery exploring power, vulnerability, and the chilling consequences of misplaced trust.
