The Kavalier Serial Murders are a chain of killings engineered to make Tony Leike appear responsible, while concealing the Kavalier’s own role and the violence’s personal motive. The case’s central reversal is that an apparent serial-murder pattern does not have a single explanation: the Kavalier exploits the crimes and evidence surrounding Leike to hide his own attacks and steer the investigation toward a false culprit.

Background and concealed pattern

The novel first frames the murders through a voice looking at newspaper photographs in a dark sewing room. The speaker has cut away the grieving families’ stories and the graphic accounts of the bodies, keeping only earlier photographs of victims smiling, apparently secure in lives that seemed to stretch ahead without obstruction. The carefully chosen images turn the victims’ former happiness into a stark counterpoint to their deaths, while the speaker’s own account casts killing as a universal human capacity and murder as a supposed act of mercy. That reasoning is presented as the speaker’s conviction, not as an established truth; its cold certainty makes the voice itself part of the mystery.

At this point, the police have not recognized a connection among the murders, though the speaker anticipates that they soon will. The gap between the killer’s confidence and the investigators’ incomplete understanding establishes the case’s governing tension: evidence can point toward a pattern without yet revealing who designed it, or why. The later investigation must therefore do more than connect victims. It must distinguish the real links among them from links deliberately planted to misdirect the police.

One important route into the pattern runs through the Hävasshütte. Missing-person inquiries establish that Adele Vetlesen and Borgny Stem-Myhre each bought a train ticket to Ustaoset for November 7. Records also show that Iska Peller paid for pairs of beds at four mountain huts, each roughly a day’s walk from the next; the last was the Hävasshütte, only half a day’s walk from Ustaoset. These travel and lodging details place separate people within the same remote route and bring the hut’s occupants into the investigation, although the records alone do not explain what happened there.

The isolation of the mountain setting gives the connection its practical importance. A recollection from Elias Skog later supplies a disturbing account of the night: awakened by sounds outside, he saw a man and a woman beneath the outhouse’s roof. Unable to see the man’s face, Elias initially mistook the woman’s movements and the hand over her mouth for signs of a sexual encounter. After the murders became public, he reconsidered what he had witnessed and wondered whether the woman had been struggling to escape. That belated change in interpretation turns an overlooked glimpse into a possible account of violence—and makes the Hävasshütte not merely a point shared by travelers, but the scene around which the concealed motive begins to form.

Motive and the false trail

The sight at the Hävasshütte first looked like a sexual assault, and Harry initially regarded Tony Leike as capable of violence. But the apparent assault did not explain the scene as he had first understood it. Harry suddenly saw the crucial reversal: it had not been a rape, and that difference supplied the motive. Adele Vetlesen had previously sent a friend an MMS while another man was having sex with her; according to her friends, she did not see the man from the hut again afterward. Harry interpreted the episode as a public betrayal that humiliated the man who witnessed it. Jealousy, rather than an unknowable impulse belonging to a mad serial killer, gave the crimes a personal cause.

That explanation could account for the killings of Adele and Tony Leike, but not by itself for the other victims. Harry proposed that they had been eliminated because they might have witnessed the Hävasshütte incident and told the police, supplying the missing motive. They also carried the knowledge of the Kavalier’s humiliation: for an unstable person, Harry argued, the prospect of others knowing about that public betrayal could itself be intolerable. The investigation’s apparent series thus encompassed both the original grievance and the removal of people who could expose it.

The Kavalier had also shaped the evidence to make Tony Leike look like the killer. Juliana Verni was paid to travel to the Congo, where the weapon had been obtained; because Leike had an economic project in that region, a Congolese connection would draw suspicion toward him. The call to Elias Skog from Leike’s home telephone seemed to reinforce the accusation, until Harry checked the office records: around the same time, three calls had gone out from Leike’s direct line at the Aker Brygge office. The home-phone call therefore did not establish that Leike had made it; it fitted a deliberate attempt to use his home and name as part of the frame.

The torn page from the Hävasshütte guestbook served the same design. By removing the names of the people who had stayed there, the Kavalier could learn who might have been present, locate them and kill them before the police could intervene. The missing page also kept his own name out of the investigators’ view. The false trail was therefore not simply a collection of clues pointing at Leike: it was a way to control who knew the hut’s connection, who could be identified as a witness, and whose identity remained concealed.

Escalation and deliberate visibility

The killings did not all serve the same immediate purpose, and the Kavalier changed how he handled the bodies as the investigation failed to follow his intended trail. Borgny Stem-Myhre was last known to have left the Mono after a fashion-magazine event, saying she wanted to go home to prepare for a jungle-and-punk-themed photo shoot. No taxi driver working nearby recognized her or recalled taking a fare to Sagene. Two Polish masons later found her fully dressed in the middle of a cellar after noticing its forced padlock. Her death had occurred between ten and eleven that night; Ketanomin was present in her blood, but she had drowned in blood from wounds in her mouth. The medical examiner counted twenty-four symmetrically arranged punctures, each exactly seven centimeters deep except those that had pierced her face. Investigators found no fingerprints, DNA, or shoe impressions; the concrete floor had been cleaned the day before. Two small gray-black stones that did not match the site’s gravel were recorded as potentially useful clues if similar stones turned up elsewhere.

In the following weeks, the Kavalier killed Borgny and Charlotte Lolles. Unlike in the killings of Adele Vetlesen and Juliana Verni, he no longer tried to hide the bodies. He instead left them where they could be found, expecting the deaths to make the police connect the women and search for the killer associated with the Leopoldsapfel. When the investigation still did not develop as he had planned, he widened the pressure: he killed Mark Olsen, a member of parliament, and displayed her at the Frognerbadet swimming pool. The increasingly public placement of victims was an attempt to force the police to see a pattern, not a retreat from concealment of his own identity.

The Kavalier then took a more direct risk to create another link to Tony Leike. While Leike was away, he entered the house through the cellar and used Leike’s telephone to call Elias Skog. On leaving, he stole a bicycle to make the intrusion resemble an ordinary break-in. He was not deterred by having left fingerprints on the desk: he knew that the police did not pursue minor cellar burglaries. He then went to Stavanger and killed Elias by gluing him to the bottom of a bathtub and turning on the water. The call, the stolen bicycle, and the choice of a seemingly routine burglary all formed part of the effort to make the murder appear connected to Leike while exploiting investigative practices that the Kavalier expected would leave his own actions unexamined.

Forensic residue and the limits of identification

A later addition to the medical examiner’s report recorded traces of iron and coltan on the inner surfaces of two of the victim’s molars. The finding adds a material trace to a case in which investigators could not identify the instrument responsible for the mouth wounds, but the report does not establish what object left the metals or who used it. Its significance therefore remains unresolved: the murders produce clues capable of inviting comparison, yet no single trace, by itself, closes the distance between a physical fact and the identity of the killer.
