Hävass Mountain Hut is the remote refuge at the center of a night whose meaning changes as the murder investigation unfolds. Its guest register preserves the names of people who were there, but when that record is deliberately damaged, the hut becomes both the source of a crucial connection and the setting for a chain of mistaken beliefs that helps drive further killings.

Setting and access

The hut lies in the Ustaoset mountain region, about half a day’s walk from Ustaoset itself. The surrounding terrain is remote enough to make a stay there feel removed from ordinary life: reaching huts in the area entails long journeys on foot, and visitors may be far from help or other witnesses. In the wider landscape, Hallingskarvet rises over a snow-covered plateau. The mountain setting is not merely a backdrop; its isolation makes the visitors’ shared presence significant while limiting what any one of them can know about the others.

Records of travel and accommodation gradually establish the hut’s place in the investigation. Adele Vetlesen, reported missing by her partner in November, bought a Norwegian State Railways ticket from Drammen to Ustaoset for November 7. Borgny Stem-Myhre bought a ticket to the same destination for that date, travelling from Kongsberg. Separately, an account belonging to Iska Peller was charged for two beds in each of four huts, spaced roughly a day’s walk apart. Hävass Mountain Hut was the final hut on that route and was only half a day’s walk from Ustaoset. These separate records make the mountain destination a point of convergence, rather than an incidental stop on one person’s journey.

The night at the hut

Elias Skog later described waking during the night and seeing two people outside near the hut’s outhouse. He could not identify the man. At the time, he interpreted what he saw as a sexual encounter and went back to sleep, disappointed that he had not seen more. After news of the murders appeared, he reconsidered the scene: the woman’s movements might have been an attempt to get free, and the man’s hand over her mouth might have been intended to stop her calling for help. His account therefore arrives first as an uncertain observation, then as a possible sighting of violence.

Harry Hole initially learns of the incident as a possible assault on Adele Vetlesen by Tony Leike. That interpretation does not hold. A later realization makes clear that the encounter was not a rape and that this reversal supplies the motive Harry had been missing. Mikael Bellman offers a related explanation for the later danger: Tony may have feared that the people who witnessed him with Adele could identify him. The hut’s importance thus rests not only on who stayed there, but on the risk created by their having seen, or potentially seen, something Tony wanted concealed.

The guest register and the killings

Sigurd Altman returned to the hut after thinking over what had happened. He tore out the guest-register page listing the names and addresses of everyone who had been there that night. He then wrote Tony a letter implying that he had witnessed Tony with Adele and demanding money, signing it in Borgny Stem-Myhre’s name. Five days later, Altman read that Borgny had been found murdered. He said he had expected the threat to lead the police to Tony, not to produce another death.

When the police failed to connect the murders, Altman used additional names from the missing page to write further letters in the names of victims. Each purported writer claimed to know about the earlier letters and raised the price of silence. Altman also cut out photographs of the victims and put them on the wall of his sewing room at the Kadok Factory beside copies of the letters. He presented the scheme as an attempt to make Tony commit errors that would allow the police to catch him; the growing number of murders instead gave Tony more practice in violence and more reason to fear that witnesses were closing in.

Tony, too, went back to the hut to look at the register. Finding the page torn out, he could not establish who else had been present. After receiving a letter in Charlotte Lolles’s name, he killed her; he later killed Mark Olsen and Elias Skog. The missing page had been intended to identify the people connected to that night, but its absence kept Tony guessing. Bellman observes that only seven people had been at the hut, yet Tony had no way to sort that small group into known witnesses and imagined threats. The hut’s register therefore becomes a practical instrument of the plot: first a record of attendance, then a means of blackmail, and finally an absence that intensifies Tony’s suspicion.

The mountain’s larger significance

The hut also belongs to a wider geography that Harry must connect. At the hospital bedside of his dying father, he recognizes the link between Leike Farm and Ustaoset, between rumors of the missing boy from Utmo Farm haunting the mountains and Tony Leike’s claim to know those mountains as his own country. The connection extends to Tony’s childhood and family: the boy in the photograph, his violent father, and his beautiful mother. Tony later explains that he built a remote cabin in the mountains and searched the plateau year after year for his mother’s remains, working alone and away from other people. That cabin is not the hut, but both places belong to the isolated mountain world through which the novel gradually brings Tony’s past and the present murders together.

The narrative first presents the people connected to Hävass Mountain Hut as scattered clues: train journeys, an unusual lodging pattern, Elias’s uncertain memory, and the missing register page. Their convergence changes the reader’s understanding of the night and of the killings that follow. The hut is consequently more than a secluded setting. It is the point where a hidden encounter, incomplete records, and competing efforts to expose Tony become entangled—and where the absence of one page helps turn uncertainty into a succession of deaths.
