Murder of Marit Olsen takes place at night at Frognerbadet, the enclosed public pool in Frogner Park. The killer forces the sitting member of Storting from a ten-metre diving tower, using a rope to make the fall fatal. The scene sets the victim’s clear desire to continue living against the deliberate arrangement of her death; later, Harry Hole identifies the killing as the third in a series of murders with a shared pattern.

Setting and Circumstances

The scene begins at about 10:45 p.m. The temperature is still nine degrees Celsius, and Marit remembers that the forecast promises even milder weather the next day. Frogner Park is empty. The pool, fenced off within the much larger park, seems to her like a place deserted out of season. That isolation is not merely atmosphere: the nearby city remains active, but its traffic and lights are too far away for anyone to hear her.

The setting also carries Marit back to childhood. She recalls stories of drowned fishermen said to haunt Tronholmen, where her grandparents lived, and remembers being frightened in the bedroom there. Those memories give the empty pool a private, ghostly significance. Yet Marit is not simply absorbed in fear or resignation. She notices that she is still breathing and thinks about the life she wants: travel to unfamiliar countries, seeing her nieces grow up, and hoping the world might become more reasonable. The contrast makes the scene’s central loss precise: her future remains imaginable to her even as the killer is closing it off.

The Assault and the Fall

Before the tower, Marit has been threatened with a knife and made to move through a gap in the pool’s fence. She had been ordered to climb over the fence but could not do so. Her fear prevents her from acting as she is told; when she tries to explain, the attacker silences her and directs her onward through the opening. The sequence establishes that she is being controlled and moved, not that she has chosen to enter the deserted pool or approach the tower.

At the top, Marit sees the empty basin and a large clock whose hands have stopped at 5:10. She wishes it were working so she could see the seconds she is still taking from death. The clock’s stopped time becomes a concrete counterpoint to her thoughts of the future: time appears suspended in the abandoned pool, while her own remaining time is being forced toward its end. The assailant tells her to jump. When his voice changes, Marit recognizes him, but the scene does not disclose his identity. A push sends her over the edge.

The rope is old-fashioned Bast-fibre rope, twisted from the fibres of linden and elm, with no elasticity. It tightens as Marit falls, but does not stop her body from striking the bottom of the pool. The account records the killing without presenting it as an accident: the rope and the tower are part of the method by which the attacker turns a forced jump into a fatal act. Once the body has fallen, the pool is quiet again.

Staging, Public Space, and Aftermath

Marit sees the empty stands as resembling a courtroom without spectators or a public execution without a crowd. The comparison gives her death a public dimension even though no audience is present. She understands that her final appearance may go unnoticed, and that she has not been able to make her fate into a signal that others will see. The scene thus distinguishes the physical publicness of the location from actual public attention: the pool is a civic leisure space, but at night it offers no witnesses to protect her.

At nine the following morning, police have cordoned off the pool by closing the entire fence and placing an officer at the entrance. Reporters circle the site and consider how to get close enough for pictures. Their interest is sharpened by Marit’s prominence as a member of Storting, with some treating that status as grounds for public access to images of the crime. The response reverses the emptiness of the night: the site is now crowded with people seeking access, but their presence comes after the murder and serves the appetite for a view rather than Marit’s safety.

Place in the Murder Investigation

Harry Hole later rejects the description of the case as a double murder and calls it a triple murder. His reasoning is that Marit is a woman alone at night, taken to a place where her life is ended by an unconventional method; he regards this as the third instance of the pattern in Oslo. His assessment links her murder to the other killings without, in this scene, explaining their individual circumstances or establishing the killer’s identity.

Gunnar Hagen agrees that keeping the inquiry small would reduce the risk of the Kriminalamt or the Norwegian Ministry of Justice learning that the murders are being investigated. He also sets a condition: if the investigation becomes public, it must not be connected to the Violent Crime Division. The consequence is an inquiry framed by secrecy and institutional risk. Marit’s murder therefore has two distinct forms of significance in the narrative: it is the end of a life whose future she still wanted, and it becomes evidence in Harry’s effort to recognize a wider sequence before the investigation can safely be acknowledged.
