The Hanging Girl

Overview

First published in 2014, The Hanging Girl is a crime novel by Danish writer Jussi Adler-Olsen and the sixth installment in his Department Q series. The series follows a Copenhagen police unit assigned to cold cases. Carl Mørck is its nominal leader, but his assistants, the enigmatic Assad and the sharp-edged Rose, often do much to set investigations in motion. Their contrasting temperaments and evolving working relationship provide a continuing thread alongside the cases. This novel combines a retrospective murder investigation with the familiar team dynamic, while extending its inquiry from Denmark to Sweden.

The case

The central case reaches back to 1997 on the Danish island of Bornholm. Alberte Goldschmid, a young folk high school student, disappears and is later found hanging high in a tree. Her death has been treated as a hit-and-run accident, but local police officer Christian Habersaat has long believed that it was murder. He spends years trying to prove his suspicion and identify the person responsible. When he contacts Carl to ask Department Q to take over, Carl initially fails to give him the response he wants. Habersaat then dies by suicide, leaving the old case newly urgent and forcing Carl and his colleagues to confront both the evidence and the circumstances surrounding the officer’s final appeal.

Carl, Assad, and Rose follow the clues Habersaat left behind and investigate the people connected to Alberte, including her fellow students and the hidden relationships around her. Their inquiry uncovers a secret connection between Alberte and a charismatic man, and leads toward a sun-worshipping group. The trail eventually points to a spiritual academy in Sweden and a figure known as Frank. As the team works to establish what happened years earlier, the case acquires a present-day danger: the investigators must also try to prevent further killings. The plot therefore moves between reconstructing the past and responding to threats that have not ended with it.

Themes and place in the series

The novel explores obsession, memory, responsibility, and the power one person can exert over others. Habersaat’s determination to solve Alberte’s death suggests the moral value of refusing to let a victim be forgotten, but his years of fixation also show how an unanswered question can consume a life. The investigation asks how secrets survive within communities, how vulnerable people can be drawn into controlling groups, and how a mistaken or incomplete account of the past can continue to shape the present. Rather than treating the mystery as a puzzle alone, the book gives weight to the human relationships and psychological pressures surrounding it.

Its writing context is also that of an established series: Adler-Olsen builds a new cold-case plot while carrying forward the tensions, humor, and personal histories of the Department Q characters, with Gordon among the team’s newer members. The cold-case format lets the narrative compare old assumptions with evidence uncovered later, while the movement from Bornholm toward Sweden broadens the investigation. Readers and reviewers may differ over the novel’s length or its standing beside other entries, but its mix of procedural inquiry, dark subject matter, and the assistants’ lively interplay is characteristic of the series. As the sixth book, it further established Department Q as an internationally recognized crime-fiction series and sustained interest in Carl, Assad, and Rose beyond any single case.

About the Author

Jussi Adler-Olsen

Life and formation

Jussi Adler-Olsen was born in Copenhagen, Denmark, on 2 August 1950. A Danish crime novelist, he has also worked as a publisher, editor, and entrepreneur. Accounts of his childhood describe an unusual formative environment: because of his father’s work, he grew up in psychiatric hospitals. Biographical material connects this experience with his later interest in psychology and character. His crime fiction gives substantial attention to motives, emotional pressures, and relationships, rather than relying on violence alone.

He studied medicine, sociology, political history, and film; the available biographical information does not establish that he completed degrees in these fields. His working life extended across several areas, and he has also been described as a guitarist in a band and a film composer. These activities form a varied background rather than a conventional, single-track literary career. Sources distinguish his nonfiction debut, published in 1984, from his fiction debut in 1997. Other biographical accounts say that he began writing around 1995, a date that can refer to the beginning of his writing career rather than the publication of his first novel.

Books and career

Adler-Olsen is best known for Department Q, a crime series centered on a Copenhagen police unit investigating cold cases. Its first volume, The Keeper of Lost Causes, appeared in 2007 and introduced detective Carl Mørck and the series’ investigative framework. The next books followed in publication order: The Absent One in 2008, A Conspiracy of Faith in 2009, The Purity of Vengeance in 2010, and The Marco Effect in 2012. The Hanging Girl, the sixth installment, was published in 2014. Later volumes include Selfies (2016), Victim 2117 (2019), and Natrium Chlorid (2021), the ninth Department Q novel listed in his curriculum vitae. The books combine individual cases with continuing character development, allowing the investigative team’s relationships and personal histories to grow across the series.

His other works include the thriller The Washington Decree, published in 2006. It is separate from Department Q and demonstrates that his writing has not been confined to the cold-case series. Across his crime fiction, he has returned to questions of secrecy, power, responsibility, and the psychological consequences of violence, while varying the plot and setting from one book to another.

Recognition and reputation

The Department Q novels made Adler-Olsen an internationally prominent Danish crime writer. The series has been translated and marketed beyond Denmark, and its central characters—Carl, the mysterious Assad, and the resourceful Rose—have become its recognizable continuing ensemble. He received the Glass Key, a major Scandinavian crime-fiction award, for work associated with the series. In 2012, the English-language edition of The Keeper of Lost Causes received the American Barry Award, helping bring the series further recognition among English-speaking readers. His fiction has also attracted screen-adaptation interest, adding to the books’ wider cultural presence.

His lasting reputation rests on the combination of accessible mysteries and attention to character psychology. The cold-case structure supplies a clear investigative question, while the team’s friction, humor, and gradually revealed histories give the series continuity beyond the resolution of any one crime. He is widely regarded as one of Denmark’s leading bestselling crime writers and an important international representative of contemporary Nordic crime fiction. Adler-Olsen is living; the available material records no death. His varied work in publishing, editing, business, music, and film forms part of his broader career, but Department Q remains the achievement most closely associated with his name.
