Glasvinge The Butterfly House

The Copenhagen series #3

Saturday, October 14th. The coronary care unit at Rigshospitalet in Copenhagen. A nurse fills a syringe with an overdose of heart medicine and enters the room of an older male patient.

Monday, six days earlier. A deliveryman is doing his rounds in central Copenhagen when he makes a macabre find: the naked body of a dead woman in a fountain on the main pedestrian street. Bizarre, symmetrical cuts cover her skin. The cause of death appears to be exsanguination.

Police Sergeant Jeppe Kørner is assigned to the case, but this time he doesn’t have his partner Anette Werner by his side. Werner is on maternity leave – or should be, rather. The investigation takes Kørner, his new partner, and Werner into the heart of the healthcare system. It’s a world where great empathy and care is shown, but ambitions fester under the surface.

Meanwhile, Esther de Laurenti ought to be writing on her novel but is suffering from a case of writer’s block. And what could be depression, as well. As her friend is suddenly admitted to Rigshospitalet’s coronary care unit, Esther seeks help from a psychiatrist who unbeknownst to her has ties to the ongoing murder case. Esther and her friend are now both at the mercy of a system in decay that’s hiding a killer, and the hours till the next death have started ticking.

The noose tightens, but around whose throat will it close?

The Butterfly House is the third novel about the Police Sergeants Jeppe Kørner and Anette Werner.

“Katrine Engberg follows up on her successful debut novel The Tenant with a captivating story that one simply cannot stop reading.”
Anders de la Motte


  • “Well-crafted. /…/  By addressing the issue of society’s treatment of the mentally ill, Engberg brings the complexities of life into this superior Danish police procedural. Fans of Scandinavian noir will hope this series has a long run.”

    Publishers Weekly, US

  • The Butterfly House is impossible to put down /…/ My highest compliments; I really liked the previous novel Blood Moon, but this one is even better.”


    Bogfidusen, Denmark

  • “With The Butterfly House, Katrine Engberg has written a phenomenal crime novel.”


    Krimifan, Denmark

  • The Butterfly House is an absurdly good crime novel with a warm and touching crime story. Engberg’s prose is as sharp as her husband’s kitchen knives, a language that insists on constantly being enjoyable.”

    Vildmedkrimi, Denmark

  • “Remarkable Engberg. A solid performance!”


    Bogfriisen, Denmark

  • The Butterfly House is murder with a purpose. This will certainly advance the crime fiction genre and give reading a purpose.”

    Københavneravisen, Denmark

  • “A real page-turner, horrifying and thrilling. The plot is well-constructed and the entertainment level high.”

    Lektør, Denmark

  • “The third bulls-eye from Engberg. Intensely suspenseful from the first till the last page.”

    Familie Journal, Denmark

  • “Katrine Engberg’s The Butterfly House resembles a magic trick. It’s elegantly executed. Nothing more will be revealed here. Read for yourself.”

    Information, Denmark

  • “Engberg writes with a great momentum and an idiomatic language that excels in sporadically flowering, almost poetic descriptions and an understated edgy humor. /…/ As a plot maker, she is as solid as an old oak, and linguistically she is as light and playful as a – deathly – butterfly.”
